Impact of Paris Climate Accord and why Trump was right to dump it

The much touted Paris Climate Accord aims at worldwide reduction of carbon dioxide emissions in order to keep global temperatures from rising more than 2°C above pre-industrial levels. This goal is purely arbitrary and based not upon any physical evidence, but upon the unproven assumption that carbon dioxide emissions play a significant role in global warming. What the Paris Accord really does is to transfer trillions of dollars from industrialized countries, mainly the US, to the sticky-fingered United Nations and to developing nations. It has a very minimal effect on global warming.

Several studies estimate the actual effects of the Accord. The most recent is from Bjorn Lomborg, published in the peer-reviewed journal, Global Policy (read full paper). Here is the paper abstract:

This article investigates the temperature reduction impact of major climate policy proposals implemented by 2030, using the standard MAGICC climate model [developed at the National Center for Atmospheric Research, Boulder, US, and University of Adelaide, Australia].

Even optimistically assuming that promised emission cuts are maintained throughout the century, the impacts are generally small.

The impact of the US Clean Power Plan (USCPP) is a reduction in temperature rise by 0.013°C by 2100.

The full US promise for the COP21 climate conference in Paris, its so-called Intended Nationally Determined Contribution (INDC) will reduce temperature rise by 0.031°C.

The EU 20-20 policy has an impact of 0.026°C, the EU INDC 0.053°C, and China INDC 0.048°C.

All climate policies by the US, China, the EU and the rest of the world, implemented from the early 2000s to 2030 and sustained through the century will likely reduce global temperature rise about 0.17°C in 2100.

REPORT: $12.7 Trillion Needed To Meet Paris Climate Accord’s Goal

by Michael Bastasch, Daily Caller

A whopping $7.4 trillion will be spent globally on new green energy facilities in the coming decades, but another $5.3 trillion is needed to meet the goals of the Paris climate accord, according to a new report.

Bloomberg New Energy Finance (BNEF) is out with a new long-term energy outlook report, this time projecting a total of $12.7 trillion to keep projected global warming below 2 degrees Celsius by the end of the century — a goal of the Paris accord. Read more

“The current focus on CO2 emissions reductions risks having a massively expensive global solution that is more damaging to societies than the problem of climate change.” – Dr. Judith Curry

But the Accord will harm poor people in developing countries:

While the plan’s costs may range as high as $1 trillion annually, none of it would have any meaningful impact on the roughly three billion people in the developing world who currently have no real access to energy.

Much of the developing world still burns dung as their chief means of cooking and heating. Realistically, the most effective means of saving their lives and improving living conditions would be to provide the steady electricity generation needed for water and sewage treatment as well as lighting and cooking.

The Paris Accord, in contrast, essentially ends any chance to help them. While natural gas and coal power plants could provide reliable, affordable electricity for these populations, the Accord aims to steadily reduce fossil fuel usage. Read more

Estimates of the Accord’s effectiveness in reducing global warming as stated above are based on analysis of surface temperatures. However, “For the past 38 years, satellites have continually tracked global temperatures. And what they’ve recorded in that time is a temperature increase averaging 0.136 degrees Celsius per decade. That means on its current trajectory the Earth could see a potential surface temperature increase of 1.36 degrees Celsius over the entire 21st century.

Noting the current warming trajectory, it appears that by simply doing nothing, the world could accomplish the main goal of the Accord.” (IBID.)

Natural variation trumps CO2

Many climate scientists claim that our carbon dioxide emissions are the principal driver of global warming. I have asked several University of Arizona professors, who make such a claim, to provide supporting physical evidence. So far, none have been able to justify the claim with physical evidence.

In this article, we will examine the Earth’s temperature and the carbon dioxide (CO2) content of the atmosphere at several time scales to see if there is any relationship. I stipulate that the greenhouse effect does exist. I maintain, however, that the ability of CO2 emissions to cause global warming is tiny and overwhelmed by natural forces. The main effect of our “greenhouse” is to slow cooling.

There is an axiom in science which says: “correlation does not prove causation.” Correlation, however, is very suggestive of a relationship. Conversely, lack of correlation proves that there is no cause-and-effect relationship.

Phanerozoic time – the past 500 million years:


Estimates of global temperature and atmospheric CO2 content based on geological and isotope evidence show little correlation between the two. Earth experienced a major ice age in the Ordovician Period when atmospheric CO2 was 4,000ppm, 10 times higher than now. Temperatures during the Cretaceous Period were rising and steamy, but atmospheric CO2 was declining.

Notice also, that for most of the time, Earth’s temperature was much warmer than now and life flourished. There were some major extinction periods, all associated with ice ages.


Berner, R.A. and Kothavala, Z, 2001, GEOCARB III: A Revised Model of Atmospheric CO2 over Phanerozoic Time, American Journal of Science, Vol. 301, February, 2001, P. 182–204

Scotese, C.R.,

Our current ice age – the past 420,000 years:

During the latter part of our current ice age, glacial-interglacial cycles occurred with a periodicity of about 100,000 years which correlates with the changes in Earth’s orbit around the sun as it changes from nearly circular to elliptical with an eccentricity of about 9%. Here we see an apparent correlation between temperature and CO2. The data are from ice cores collected at the Vostok station in Antarctica. The scientists working on the Vostok core noticed that temperature changes PRECEDED changes in CO2 concentration by about 800 years. Again, we see that CO2 doesn’t have much influence on temperature, but temperature has great influence on CO2concentration because temperature controls CO2 solubility in the ocean.

The Holocene – the past 10,000 years:

The Holocene represents the current interglacial period. For most of the past 10,000 years, temperature was higher than now. CO2 was fairly steady below 300ppm (vs over 400ppm now). There were cycles of warm and cool periods at a periodicity of 1200 to 1500 years. This periodicity correlates with the interplay of the several solar cycles. The sun itself goes through cycles of solar intensity and magnetic flux. When the cycles are in a strong phase, the amount of cosmic rays entering the atmosphere is reduced, there are fewer clouds to block the sun, so it is warmer. When solar cycles wane, as is beginning to happen now, more cosmic rays enter the atmosphere and produce more clouds which block the sun, so it becomes cooler. The number of sunspots (hence magnetic flux) varies on an average cycle of 11 years. There are also 87-year (Gliessberg) and 210-year (DeVriess-Suess) cycles in the amplitude of the 11-year sunspot cycle which combine to form an approximately 1,500-year cycle of warming and cooling.

The 20th Century:


The first part of the 20th Century experienced warming in the 1920s and 1930s comparable to current temperatures. According to NASA, atmospheric CO2 rose from 295ppm in 1900 to 311ppm in 1940. Major emissions from burning fossil fuels, however, commenced after WWII in the mid 1940s. The period 1940-1970 saw a CO2 rise of 311ppm to 325ppm. That period also showed global cooling to such an extent that climate scientists were predicting a return to glacial conditions. From about 1980 to 2000, CO2 rose from 339ppm to 370ppm and we had warming during that period until the super El Nino of 1997/1998. Some of this data has been “corrected” by NOAA.

The 21st Century so far 

Microwave data from satellites converted to temperature.

Between the El Nino of 1997 and that of 2016, there have been temperature fluctuations but no net warming. Atmospheric CO2 rose from 363ppm to 407ppm today. It seems that there is no correlation between global temperature and CO2.

As I said at the beginning, while the CO2-induced greenhouse effect has some hypothetical warming potential, that warming is tiny and overwhelmed by the forces of natural variation. So far, I have seen no physical evidence to contradict my contention.

The Oman geoengineering scheme to save the planet

A story in the Arizona Daily Star, 4-14-17 (the great march for science issue) shows how some scientists create the most tenuous links between their research and climate change as a plea for funding.

This story is “Oman’s mountains may hold clues for reversing climate change.” (Link) The lede: “Deep in the jagged red mountains of Oman, geologists are searching for an efficient and cheap way to remove carbon dioxide from the air and oceans — and perhaps begin to reverse climate change. They are coring samples from one of the world’s only exposed sections of the Earth’s mantle to uncover how a spontaneous natural process millions of years ago transformed carbon dioxide into limestone and marble.”

The researchers are excited because the exposed mantle rock is mostly peridotite, a coarse-grained igneous rock made up of the minerals olivine and pyroxene, both magnesium silicates. “They hope to answer the question of how the rocks managed to capture so much carbon over the course of 90 million years — and to see if there’s a way to speed up the timetable.” A researcher goes on to say, ““Every single magnesium atom in these rocks has made friends with the carbon dioxide to form solid limestone, magnesium carbonate, plus quartz.”

A couple of nitpicks: Limestone is calcium carbonate, not magnesium carbonate (Calcium and magnesium together with carbonate form a rock called dolomite). Marble is a metamorphic rock which requires heat and/or pressure to form. That “spontaneous natural process” happened not only millions of years ago, but is a continuing natural process in the ocean when calcium ions derived from weathering of surface rocks combine with carbonate ions in the ocean. Basaltic ocean crustal rocks act as a buffer by continuously removing CO2 from the ocean by combining carbonate with calcium derived from surface weathering of rocks.

Their great scheme is this: “a drilling operation could cycle carbon-rich water into the newly formed seabed on oceanic ridges far below the surface. Just like in Oman’s mountains, the submerged rock would chemically absorb carbon from the water. The water could then be cycled back to the surface to absorb more carbon from the atmosphere, in a sort of conveyor belt.”

Perhaps the researchers made the climate change link to their research just to suck up grant money so they can continue studying. The geology is interesting, but their idea sounds like another crazy, expensive, and totally unnecessary geoengineering scheme. (See Wacky Geoengineering Schemes to Control Climate)

Carbon dioxide is necessary for life on Earth

Earth’s climate has been changing for at least four billion years in cycles large and small. Few in the climate debate understand those changes and their causes. Many are fixated on carbon dioxide (CO2), a minor constituent of the atmosphere, but one absolutely necessary for life as we know it. Perhaps this fixation derives from ulterior political motives for controlling the global economy. For others, the true believers, perhaps this fixation derives from ignorance.

Greenpeace co-founder Dr. Patrick Moore has written an excellent summary of the history of carbon dioxide on Earth titled, “The Positive Impact of Human CO2 Emissions On the Survival of Life on Earth.” In this 24-page paper, Moore notes that we came dangerously close to losing plant life on Earth about 18,000 years ago, when CO2 levels approached 150 ppm, below which plant life can’t sustain photosynthesis. Currently, atmospheric CO2 stands at about 400 ppm which is about one-third the level for optimum plant growth.

Phanerozoic temp CO2 moore

Here is the executive summary of Moore’s paper:

This study looks at the positive environmental effects of carbon dioxide (CO2) emissions, a topic which has been well established in the scientific literature but which is far too often ignored in the current discussions about climate change policy. All life is carbon based and the primary source of this carbon is the CO2 in the global atmosphere. As recently as 18,000 years ago, at the height of the most recent major glaciation, CO2 dipped to its lowest level in recorded history at 180 ppm, low enough to stunt plant growth.

This is only 30 ppm above a level that would result in the death of plants due to CO2 starvation. It is calculated that if the decline in CO2 levels were to continue at the same rate as it has over the past 140 million years, life on Earth would begin to die as soon as two million years from now and would slowly perish almost entirely as carbon continued to be lost to the deep ocean sediments. The combustion of fossil fuels for energy to power human civilization has reversed the downward trend in CO2 and promises to bring it back to levels that are likely to foster a considerable increase in the growth rate and biomass of plants, including food crops and trees. Human emissions of CO2 have restored a balance to the global carbon cycle, thereby ensuring the long-term continuation of life on Earth.

Moore presents a concise history of CO2 beginning in the Cambrian Period 540 million years ago when CO2 was about 7,000 ppm. He follows that with a discussion of how carbon is distributed today between the atmosphere, oceans, plant life, and rocks.

In his concluding remarks, Moore briefly discusses the politics of CO2 and notes: ” Lost in all these machinations is the indisputable fact that the most important thing about CO2 is that it is essential for all life on Earth and that before humans began to burn fossil fuels, the atmospheric concentration of CO2 was heading in a very dangerous direction for a very long time.”

There is no physical evidence that our CO2 emissions from burning fossil fuels will produce catastrophic climate change. Moore asks, “Given that the optimum CO2 level for plant growth is above 1,000 ppm and that CO2 has been above that level for most of the history of life, what sense does it make to call for a reduction in the level of CO2 in the absence of evidence of catastrophic climate change?”

You can read Moore’s full paper here.

Also of interest is a 40-page paper published by the Canadian Friends of Science Society entitled “A Confluence of Carbonbaggers.” – great title. Here is part of the executive summary:

Given that in most industries, margins of error are required to be small, this paper reviews the substantial failings of the IPCC in everything from the original premise that human activity producing greenhouse gases was the primary cause of recent warming, to vast statistical errors in climate models that are 500 and 600% off trend.

Few average citizens have any knowledge of these goings on – despite the fact that billions of their tax dollars are vanishing every year on causes proclaimed by this august organization and echoed around the world by enthusiastic Environmental Non-Governmental Organizations (ENGOs) who find climate catastrophe predictions the easiest way to raise money to ‘save the planet’ – all the while demonizing traditional industries that have provided jobs, energy and resources that have created our modern, industrialized world.

This report is a compilation of errors, false and wildly exaggerated predictions, and the IPCC’s claim that it in fact ‘makes no recommendation of any kind on any topic’ – effectively washing its hands of responsibility for the damage its reports and meetings have done in the Western world. National economies have been ruined, investment markets distorted, industries devastated, thousands have died prematurely due to sharp rise in power prices across the UK and Europe as the poor and middle class have been pushed into ‘heat-or-eat’ poverty – and yet governments still persist in designing faulty climate and economic policies based on flawed documents from the IPCC – cited as ‘the authority on climate change.’

A Modest Proposal: Triple Your Carbon Footprint

Patrick Moore asks – Should We Celebrate Carbon Dioxide?

At the annual meeting of the Global Warming Policy Foundation, Dr. Patrick Moore, a founder of Greenpeace, put carbon dioxide in perspective and showed why policies and efforts to reduce atmospheric carbon dioxide are not only futile, but also dangerous to life on Earth. You can read the full transcript of the speech here. Dr. Moore left Greenpeace when that organization lost its strong humanitarian orientation and became radicalized with the belief that humans are the enemies of the earth.

Dr. Moore believes that the current concentration of carbon dioxide in the atmosphere, 400ppm, is dangerously low and much lower that it has been for most of Earth’s history. He says we and the planet would be better off with a concentration closer to 2,000ppm.

Here are some excerpts from his speech:

Let’s begin with our knowledge of the long-term history of the Earth’s temperature and of CO2 in the Earth’s atmosphere. I will focus on the past 540 million years since modern life forms evolved. It is glaringly obvious that temperature and CO2 are in an inverse correlation at least as often as they are in any semblance of correlation. Two clear examples of reverse correlation occurred 150 million years and 50 million years ago. At the end of the Jurassic temperature fell dramatically while CO2 spiked. During the Eocene Thermal Maximum, temperature was likely higher than any time in the past 550 million years while CO2 had been on a downward track for 100 million years. This evidence alone sufficient to warrant deep speculation of any claimed lock-step causal relationship between CO2 and temperature.

The Devonian Period beginning 400 million years ago marked the culmination of the invasion of life onto the land. Plants evolved to produce lignin, which in combination with cellulose, created wood which in turn for the first time allowed plants to grow tall, in competition with each other for sunlight. As vast forests spread across the land living biomass increased by orders of magnitude, pulling down carbon as CO2 from the atmosphere to make wood. Lignin is very difficult to break down and no decomposer species possessed the enzymes to digest it. Trees died atop one another until they were 100 metres or more in depth. This was the making of the great coal beds around the world as this huge store of sequestered carbon continued to build for 90 million years. Then, fortunately for the future of life, white rot fungi evolved to produce the enzymes that can digest lignin and coincident with that the coal-making era came to an end.

A well-documented record of global temperature over the past 65 million years shows that we have been in a major cooling period since the Eocene Thermal Maximum 50 million years ago. The Earth was an average 16C warmer then, with most of the increased warmth at the higher latitudes. The entire planet, including the Arctic and Antarctica were ice-free and the land there was covered in forest.

The ancestors of every species on Earth today survived through what may have been the warmest time in the history of life. It makes one wonder about dire predictions that even a 2C rise in temperature from pre-industrial times would cause mass extinctions and the destruction of civilization. Glaciers began to form in Antarctica 30 million years ago and in the northern hemisphere 3 million years ago. Today, even in this interglacial period of the Pleistocene Ice Age, we are experiencing one of the coldest climates in the Earth’s history.

Coming closer to the present we have learned from Antarctic ice cores that for the past 800,000 years there have been regular periods of major glaciation followed by interglacial periods in 100,000 year-cycles. These cycles coincide with the Milankovitch cycles that are tied to the eccentricity of the Earth’s orbit and its axial tilt. It is highly plausible that these cycles are related to solar intensity and the seasonal distribution of solar heat on the Earth’s surface. There is a strong correlation between temperature and the level of atmospheric CO2 during these successive glaciations, indicating a possible cause-effect relationship between the two. CO2 lags temperature by an average of 800 years during the most recent 400,000-year period, indicating that temperature is the cause, as the cause never comes after the effect.

Looking at the past 50,000 years of temperature and CO2 we can see that changes in CO2 follow changes in temperature. This is as one could expect, as the Milankovitch cycles are far more likely to cause a change in temperature than a change in CO2. And a change in the temperature is far more likely to cause a change in CO2 due to out-gassing of CO2 from the oceans during warmer times and an in-gassing (absorption) of CO2 during colder periods. Yet climate alarmists persist in insisting that CO2 is causing the change in temperature, despite the illogical nature of that assertion.

Coming back to the relationship between temperature and CO2 in the modern era we can see that temperature has risen at a steady slow rate in Central England since 1700 while human CO2 emissions were not relevant until 1850 and then began an exponential rise after 1950. This is not indicative of a direct causal relationship between the two. After freezing over regularly during the Little Ice Age the River Thames froze for the last time in 1814, as the Earth moved into what might be called the Modern Warm Period.

There was a 30-year period of warming from 1910-1940, then a cooling from 1940 to 1970, just as CO2 emissions began to rise exponentially, and then a 30-year warming from 1970-2000 that was very similar in duration and temperature rise to the rise from 1910-1940. One may then ask “what caused the increase in temperature from 1910-1940 if it was not human emissions? And if it was natural factors how do we know that the same natural factors were not responsible for the rise between 1970-2000.” You don’t need to go back millions of years to find the logical fallacy in the IPCC’s certainty that we are the villains in the piece.

Coming to the core of my presentation, CO2 is the currency of life and the most important building block for all life on Earth. All life is carbon-based, including our own. Surely the carbon cycle and its central role in the creation of life should be taught to our children rather than the demonization of CO2, that “carbon” is a “pollutant” that threatens the continuation of life. We know for a fact that CO2 is essential for life and that it must be at a certain level in the atmosphere for the survival of plants, which are the primary food for all the other species alive today. Should we not encourage our citizens, students, teachers, politicians, scientists, and other leaders to celebrate CO2 as the giver of life that it is?

It is a proven fact that plants, including trees and all our food crops, are capable of growing much faster at higher levels of CO2 than present in the atmosphere today. Even at the today’s concentration of 400 ppm plants are relatively starved for nutrition. The optimum level of CO2 for plant growth is about 5 times higher, 2000 ppm, yet the alarmists warn it is already too high. They must be challenged every day by every person who knows the truth in this matter. CO2 is the giver of life and we should celebrate CO2 rather than denigrate it as is the fashion today.

Let’s look at where all the carbon is in the world, and how it is moving around.

Today, at just over 400 ppm CO2 there are 850 billion tons of CO2 in the atmosphere. By comparison, when modern life-forms evolved over 500 million years ago there was nearly 15,000 billion tons of CO2 in the atmosphere, 17 times today’s level. Plants and soils combined contain more than 2,000 billion tons of carbon, more that twice as much as the entire global atmosphere. The oceans contain 38,000 billion tons of dissolved CO2, 45 times as much as in the atmosphere. Fossil fuels, which were made from plants that pulled CO2 from the atmosphere account for 5,000 – 10,000 billion tons of carbon, 6 – 12 times as much carbon as is in the atmosphere.

But the truly stunning number is the amount of carbon that has been sequestered from the atmosphere and turned into carbonaceous rocks. 100,000,000 billion tons, that’s one quadrillion tons of carbon, have been turned into stone by marine species that learned to make armour-plating for themselves by combining calcium and carbon into calcium carbonate. Limestone, chalk, and marble are all of life origin and amount to 99.9% of all the carbon ever present in the global atmosphere. The white cliffs of Dover are made of the calcium carbonate skeletons of coccolithophores, tiny marine phytoplankton.

The vast majority of the carbon dioxide that originated in the atmosphere has been sequestered and stored quite permanently in carbonaceous rocks where it cannot be used as food by plants.

Beginning 540 million years ago at the beginning of the Cambrian Period many marine species of invertebrates evolved the ability to control calcification and to build armour plating to protect their soft bodies. Shellfish such as clams and snails, corals, coccolithofores (phytoplankton) and foraminifera (zooplankton) began to combine carbon dioxide with calcium and thus to remove carbon from the life cycle as the shells sank into sediments; 100,000,000 billion tons of carbonaceous sediment. It is ironic that life itself, by devising a protective suit of armour, determined its own eventual demise by continuously removing CO2 from the atmosphere. This is carbon sequestration and storage writ large. These are the carbonaceous sediments that form the shale deposits from which we are fracking gas and oil today. And I add my support to those who say, “OK UK, get fracking”.

The past 150 million years has seen a steady drawing down of CO2 from the atmosphere. There are many components to this but what matters is the net effect, a removal on average of 37,000 tons of carbon from the atmosphere every year for 150 million years. The amount of CO2 in the atmosphere was reduced by about 90% during this period. This means that volcanic emissions of CO2 have been outweighed by the loss of carbon to calcium carbonate sediments on a multi-million year basis.

If this trend continues CO2 will inevitably fall to levels that threaten the survival of plants, which require a minimum of 150 ppm to survive. If plants die all the animals, insects, and other invertebrates that depend on plants for their survival will also die.

How long will it be at the present level of CO2 depletion until most or all of life on Earth is threatened with extinction by lack of CO2 in the atmosphere?

During this Pleistocene Ice Age, CO2 tends to reach a minimum level when the successive glaciations reach their peak. During the last glaciation, which peaked 18,000 years ago, CO2 bottomed out at 180 ppm, extremely likely the lowest level CO2 has been in the history of the Earth. This is only 30 ppm above the level that plants begin to die. Paleontological research has demonstrated that even at 180 ppm there was a severe restriction of growth as plants began to starve. With the onset of the warmer interglacial period CO2 rebounded to 280 ppm. But even today, with human emissions causing CO2 to reach 400 ppm plants are still restricted in their growth rate, which would be much higher if CO2 were at 1000-2000 ppm.

Here is the shocking news. If humans had not begun to unlock some of the carbon stored as fossil fuels, all of which had been in the atmosphere as CO2 before sequestration by plants and animals, life on Earth would have soon been starved of this essential nutrient and would begin to die. Given the present trends of glaciations and interglacial periods this would likely have occurred less than 2 million years from today, a blink in nature’s eye, 0.05% of the 3.5 billion-year history of life.

There is much more in Moore’s speech; follow the link above to read the whole thing.

EPA emission standards for trucks: heavy cost, no benefit

At a cost of only $30 billion, new EPA regulations may save us from 0.0026°C of global warming by the year 2100.

According to an EPA report (971 pages) [link]: “The Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA), on behalf of the Department of Transportation, are each proposing changes to our comprehensive Heavy-Duty National Program that would further reduce greenhouse gas emissions (GHG) and increase fuel efficiency for on-road heavy-duty vehicles,…”

The National Center for Policy Analysis estimates that “The Environmental Protection Agency’s second round of heavy-duty truck efficiency standards could cost more than $30 billion.” – costs that will be passed on to consumers.

“Auto manufacturers and the freight and long-haul transportation industry already understand the importance of fuel efficiency. Nearly 3 million heavy-duty Class 8 trucks carry approximately 70 percent of America’s freight, consuming more than 50 billion gallons in fuel and spending more than $140 billion in diesel costs. The industry operates on razor-thin margins and plans its driving routes down to the tenth of a mile to save on fuel costs.” – Nicolas Loris, The Daily Signal

The Obama administration says these new regulations are necessary to meet Obama’s carbon dioxide reduction goals.

The EPA claims “The proposed standards are expected to lower CO2 emissions by approximately 1 billion metric tons…”

So, what benefit will we get for $30 billion? EPA’s own figures show no benefit to the environment and no effect on global climate.

According to the EPA report linked above, the new regulations will accomplish the following (page 6-45): “As a result of the proposal’s emissions reductions from the proposed

alternative relative to the baseline case, by 2100 the concentration of atmospheric CO2 is

projected to be reduced by approximately 1.1 to 1.2 parts per million by volume (ppmv), the

global mean temperature is projected to be reduced by approximately 0.0026 to 0.0065°C, and

global mean sea level rise is projected to be reduced by approximately 0.023 to 0.057 cm.” Wow!

Among the first things the next President should do is to issue an executive order forbidding federal agencies from regulating carbon dioxide emissions and rescind all regulations that do so.

The U.S. Supreme Court recently ruled against the EPA on certain power plant emissions (see here). It remains to be seen whether the principles cited in that case will be extended to motor vehicles.

Berkeley scientists claim to have directly measured carbon dioxide warming the Earth – So what?

The scientific press is hyping research by Lawrence Berkeley National Laboratory that claims to have, for the first time, measured radiative forcing by carbon dioxide. Even if they have, it’s no big deal because such forcing is assumed from basic physics. They also claim that their measurement provides proof of anthropogenic global warming. But, as we shall see, they may be putting effect before cause.

Seth Borenstein, the Associated Press’ chief climate alarmist, writes “Scientists have witnessed carbon dioxide trapping heat in the atmosphere above the United States, chronicling human-made climate change in action.”

The Berkeley press release is titled “First direct observation of carbon dioxide’s increasing greenhouse effect at the Earth’s surface.” The paper, published in Nature, is somewhat more modest in its claim: “Observational determination of surface radiative forcing by CO2 from 2000 to 2010.”

Within the press release, one of the scientists is quoted as saying, “”We see, for the first time in the field, the amplification of the greenhouse effect because there’s more CO2 in the atmosphere to absorb what the Earth emits in response to incoming solar radiation.”

First, some background on what was done.

The scientists measured down-welling infrared radiation using Atmospheric Emitted Radiance Interferometer spectra from two stations located in Oklahoma and Alaska over the period from 2000 to 2010 during which atmospheric carbon dioxide increased by 22 parts per million. They claim to have 3300 measurements from Alaska and 8300 measurements from Oklahoma. Keep those numbers in mind.

They found that the down-welling radiation increased during that period and attribute that increase to the rise of carbon dioxide.

Some possible problems:

I wonder why the specific time period was chosen. In 2010 a strong La Nina produced a relatively cool tropospheric temperature, while in 2010 a strong El Nino produced a relatively warm tropospheric temperature. The difference was about half a degree Centigrade. A warmer atmosphere will intrinsically produce more down-welling infrared radiation regardless of its composition. So, was the increased down-welling radiation due to increased CO2 or increased temperature? I think they may be confusing cause and effect.

Also curious is that another study (See Evidence that CO2 emissions do not intensify the greenhouse effect ), using the same type of instruments, made 800,000 measurements during the period 1996 to 2010 and found a significant decrease in down-welling infrared radiation.

The Berkeley researchers claim that only about 10 percent of their increased down-welling radiation came from carbon dioxide. As far as I can tell, however, the emissions from carbon dioxide fall within the spectra emitted by water vapor, but the researchers claim a mathematical manipulation allows them to distinguish the 10 percent of radiation from carbon dioxide versus the 90 percent from water vapor and other gases in the atmosphere.

The Berkeley researchers claim to have found a radiation increase of “0.2 Watts per square meter per decade.” How much is that? German physical chemist Dr. Siegfried Dittrich notes:

“The number for the increase in CO2-dependent back radiation given by Nature of 0.2 watt/m2 per decade is indeed in reality nothing more than trifle. Why would the earth be shocked when 1367 watts per square meter strikes the surface at noon along the equator? The ever-changing deviations from this so-called solar constant mean value are in fact considerably greater than the above given 0.2 watts/m2.” An additional complication is that the measurements by Berkeley researchers was for only cloud-free areas.

Another paper in Geophysical Research Letters: “On the Incident Solar Radiation in CMIP5 Models” finds sampling errors much larger than the 0.2 Watts per square meter that the Berkeley researchers claim to have measured. Here is the paper abstract:

“Annual incident solar radiation at the top of atmosphere (TOA) should be independent of longitudes. However, in many Coupled Model Intercomparison Project phase 5 (CMIP5) models, we find that the incident radiation exhibited zonal oscillations, with up to 30 W/m2 of spurious variations. This feature can affect the interpretation of regional climate and diurnal variation of CMIP5 results. This oscillation is also found in the Community Earth System Model (CESM). We show that this feature is caused by temporal sampling errors in the calculation of the solar zenith angle. The sampling error can cause zonal oscillations of surface clear-sky net shortwave radiation of about 3 W/m2 when an hourly radiation time step is used, and 24 W/m2 when a 3-hour radiation time step is used.”

The alleged measurement could easily be instrument error.

There is still a question about whether they saw what they claimed to have seen. This may be an example of confirmation bias, they saw what they wanted to see based on equivocal evidence.

But in the end, to paraphrase a prominent politician: what difference does it make at this point in time?


Surprising results from NASA’s Orbiting Carbon Observatory

Results from NASA’s Orbiting Carbon Observatory show that atmospheric concentration of carbon dioxide is highest in the Southern Hemisphere (or very close to the equator) – not in the areas of all that fossil-fuel burning in the Northern Hemisphere.

In July, 2014, NASA launched a satellite which is dedicated to measure atmospheric carbon dioxide concentration from space. NASA describes it as follows:

“The Orbiting Carbon Observatory 2 (OCO-2) is NASA’s first dedicated Earth remote sensing satellite to study atmospheric carbon dioxide from Space. OCO-2 will be collecting space-based global measurements of atmospheric CO2 with the precision, resolution, and coverage needed to characterize sources and sinks on regional scales. OCO-2 will also be able to quantify CO2 variability over the seasonal cycles year after year.”

NASA has just released data from that satellite for the period October 1 through November 11, 2014. Brighter colors on the map show areas with higher concentrations of carbon dioxide in the atmosphere. Presumably, those areas are emitting carbon dioxide. The surprise is that the Southern Hemisphere is the big emitter during this time period, not the Northern Hemisphere where we are burning fossil fuels to generate electricity, run our automobiles, and heat our homes and businesses. The only exception seems to be China where they are burning great quantities of coal.

OCO NASA Nov2014

So what accounts for all those emissions in the Southern Hemisphere? Here I will do some speculation.

Hot spots occur in the Amazon and in sub-tropical Africa. There, carbon dioxide emissions could be coming from rotting vegetation and/or from burning to clear jungle for agriculture.

The hot spots in the Western Pacific (right side of graphic above) are interesting. Martin Hovland, Geophysicist and Professor Emeritus, Center for Geobiology, University of Bergen, Norway, suggests these carbon dioxide emissions are from volcanoes and tectonically active areas on the sea floor. (See his post here).

Hovland presents an annotated version of the map above:

OCO Hovland

Hovland writes:

“Using the Smithsonian Volcano database, it is seen that these CO2-hotspots occur above seafloor features which are suspected to issue CO2, CH4 and occasionally large amounts of heat (especially for FH and EH). Here, it can be seen that the TH occurs over a deep-water accretionary subduction wedge. This is a collision zone, where huge amounts of oceanic sediments pile up before they sink into and are swallowed up beneath the island masses to the north. In such settings, it is well-known that continuous seepage of methane occurs out of the seafloor. Therefore, it is here speculated that the underwater and aerial oxidation of this excess methane gas provides the regional CO2-anomaly detected by OCO2.

The seafloor beneath the FH is also highly tectonized (Fig. 3), but in a completely different fashion to that of the TH. At Fiji, there are both colliding plates and rifting zones. The whole region is highly contorted and there are lots of seepage, both hot vents and cold, methane-dominated vents. Transmittal of methane and CO2 to the atmosphere is likely also here.”

(Note: methane quickly reacts with oxygen to produce carbon dioxide.)

These tectonically active areas contain many sub-marine volcanoes.

NASA has (perhaps unwittingly) provided proof that natural carbon dioxide emissions are responsible for most of the rise seen in atmospheric carbon dioxide. In fact, in 2001, the Energy Information Administration produced a table which shows (with a little arithmetic) that anthropogenic activities account for only 3 percent of the total annual carbon dioxide flux.

Global CO2 emissions EIA IPCC

Now, look back at the first graphic. Notice that the mapped range is 387ppm to 402ppm, a difference of 15ppm. Near-surface daily variation can be greater than 30ppm, but NASA claims that variation range decreases with altitude.

Some questions: Is NASA measuring something real? What is the actual range of instrumental error? Does the human contribution fall within that error range? See if you can figure out instrumental error from a rather dense NASA document here.

For some perspective, I remind you that your exhaled breath contains 40,000ppm carbon dioxide.

By the way, back in November, NASA released a computer-generated animation video of global carbon dioxide concentrations based on computer modeling conducted in 2006. The input data were surface measurements of carbon dioxide emissions from burning fossil fuels and completely ignored natural sources. That computer-based model is pretty, but seems to be contradicted by actual measurements by the satellite system. The video, for some reason, puts the highest carbon dioxide concentrations in the Arctic. Another case of garbage in, garbage out. Take a look here.

Evidence that CO2 emissions do not intensify the greenhouse effect

Why Your Carbon Footprint doesn’t Matter

National Climate Assessment lacks physical evidence

Many people cite the latest National Climate Assessment report as an authority that proves human carbon dioxide emissions are the main cause of recent warming. But reading the report shows a different story.

The 2014 National Climate Assessment (NCA) claims on page 7: “Multiple lines of independent evidence confirm that human activities are the primary cause of the global warming of the past 50 years.”

What physical evidence does the NCA give as proof that human carbon dioxide emissions play a significant role in global temperature? In my opinion they present no unequivocal evidence.

NCA cites three main lines of “evidence” in the report (pages 23 & 24):

NCA: “The first line of evidence is our fundamental understanding of how certain gases trap heat, how the climate system responds to increases in these gases, and how other human and natural factors influence climate.”

My response: That’s a claim, not evidence. If their “fundamental understanding” is so good, why then do modeled atmospheric temperature projections diverge so widely from actual measurements? (Graph source)

Spencer models vs real temp

NCA: “The second line of evidence is from reconstructions of past climates using evidence such as tree rings, ice cores, and corals. These show that global surface temperatures over the last several decades are clearly unusual, with the last decade (2000-2009) warmer than any time in at least the last 1300 years and perhaps much longer.”

My response: First, evidence of warming does not constitute evidence of the cause of warming. Second, physical evidence shows that current warming is not unusual.

The temperature reconstruction below using tree ring data shows current temperatures are not unusual, and, in fact cooler than the past.

09_geo_tree_ring_northern_europe_climate1.jpg  1873×726

A closer look at the reconstructed temperature shows the current warming is nothing unusual.

2000 year reconstructed tempJPG


NCA: “The third line of evidence comes from using climate models to simulate the climate of the past century, separating the human and natural factors that influence climate.”

My response: Again, computer model simulations are not physical evidence, they are merely speculations that depend on input assumptions. The computer simulations were exercises in curve fitting, massaging the data until it produced the desired result. To show how ridiculous this is, an Australian science writer produced a “tongue-in-cheek” correlation between U.S. First Class postal rates and temperature. (Source) The correlation of postal rates with temperature is better than that of CO2. The graph runs from 1880 to 2009. This demonstrates that correlation does not prove causation.



NCA also claims additional “evidence” in Appendix 3 which begins on page 735. Let’s take a look.

NCA Supplemental message 1:
“…the natural greenhouse effect is being artificially intensified by human activities.”

My response: If the greenhouse effect has been intensified, then we should see a decrease in outgoing long-wave infrared radiation. However, satellite measurements from NOAA show a slight increase. (See discussion here).

Outgoing radiation vs temp NOAA

While more infrared radiation is escaping to space, there has been a decrease in down-welling infrared radiation from greenhouse gases, that is radiation from the atmosphere to the surface. An independent study, published in the Journal of Climate, based on 800,000 observations, find there has been a significant decrease in long-wave infrared radiation from increasing greenhouse gases over the 14 year period 1996-2010 in the US Great Plains. CO2 levels increased about 7% over this period and according to AGW theory, down-welling long-wave infrared radiation should have increased over this period with buildup of carbon dioxide.

Two independent measures of the “greenhouse effect” show that it is weakening even though we are putting more CO2 in the atmosphere. Why is this happening? In my opinion it is happening because a much stronger greenhouse gas, water vapor, is decreasing. That alone shows that CO2 has very little influence on global temperature.  The graph below shows how relative humidity has been decreasing since 1948 (humidity data from NOAA).


NCA Supplemental Message 2:
“Global trends in temperature and many other climate variables provide consistent evidence of a warming planet.”

My response: As stated above, evidence of warming does not speak to cause.

NCA Supplemental Message 3:
“Natural variability, including El Niño events and other recurring patterns of ocean-atmosphere
interactions, influences global and regional temperature and precipitation over timescales ranging from months up to a decade or more.”

My response: I agree.

NCA Supplemental Message 4:
“Human-induced increases in atmospheric levels of heat-trapping gases are the main cause of observed climate change over the past 50 years. The ‘fingerprints’ of human-induced change also have been identified in many other aspects of the climate system, including changes in ocean heat content, precipitation, atmospheric moisture, and Arctic sea ice.”

My response: According to climate models, the rate of warming should increase by 200-300% with altitude in the tropics, peaking at around 10 kilometers – a characteristic “fingerprint” for greenhouse warming. However, measurements by weather balloons and satellites show the opposite result: no increasing temperature trend with altitude.  In the graphic below, the computer predicted temperature distribution is on the left; measured observations, i.e., reality is on the right.

Models vs data

 The remainder of the “messages”  deal with computer modeling and some propaganda, not evidence.
Bottom Line: NCA presents no unequivocal evidence that supports their contention of significant human induced warming.

P.S. It should be noted also that the UN’s IPCC, in the thousands of pages that constitute five major reports, similarly fails to provide any physical or observational evidence supporting the contention that human carbon dioxide emissions play a significant role in global climate change.

The reasons for rejecting efforts to regulate and reduce carbon dioxide

Ready for a pop quiz? Name a colorless, odorless, tasteless gas that is found in the atmosphere in relatively minute quantities and is essential to nearly all life on earth. ___________. Time’s up! The answer is carbon dioxide.

Carbon dioxide, or CO2, was probably not the first molecule you thought to name. After all, in today’s world CO2 is given a bad rap. Ironically, some people even refer to the emission of this life-giving and life-sustaining gas into the atmosphere as “carbon pollution.” They fear its accumulation in the air because of computer model projections, which forecast a future of dangerous global warming and a host of other climate- and extreme-weather-related catastrophes if atmospheric CO2 concentrations continue to rise. And, therefore, in an effort to alleviate their concerns, these individuals seek government regulation of CO2 emissions as part of their overall objective to reduce the CO2 content of the air.

Efforts to regulate CO2 and reduce its concentration in the atmosphere, however, are way off the mark. Carbon dioxide is not a pollutant; and its increase in the air will have little, if any, impact on future climate. Literally thousands of scientific studies have demonstrated such. The recent work of the Nongovernmental International Panel on Climate Change (NIPCC), for example, highlights many of the problems, inconsistencies and outright contradictions that exist between climate model projections and real-world observations. In a 1,000-page report released this past September, the NIPCC concluded there is nothing unusual, unnatural or unprecedented about Earth’s current climate and that the impact of rising CO2 on future climate will be small, if not negligible, which conclusion is a far cry from climate catastrophe.

Another damning indictment of the rising-CO2-will-cause-dangerous-global-warming narrative is seen in the failure of the climate models to predict the current plateau in global temperature. Despite an eight percent increase in atmospheric CO2, over the past 17 years, the earth experienced no net increase in temperature, yet all of the computer models upon which the vision of dangerous global warming is based projected it should have warmed.

Aside from having a rather benign – or possibly even nil – effect on climate, there are other reasons for rejecting efforts to regulate and reduce carbon dioxide.

Atmospheric CO2 is the building block of life. It is the primary raw material or “food” that plants utilize during the process of photosynthesis to construct their tissues and grow. And, as conclusively demonstrated in the peer-reviewed scientific literature, the modern rise in CO2 is benefiting the biosphere in multiple ways.

In general, atmospheric CO2 enrichment endows plants with three main benefits. The first and most recognized is enhanced plant productivity. Typically, a 300-parts-per- million (ppm) increase in the air’s CO2 content (which is expected to occur by the end of this century) will raise the productivity of most herbaceous plants by about one-third and most woody plants by about one-half. Such stimulation is generally manifested by an increase in the number of branches and tillers, more and thicker leaves, more extensive root systems and more flowers and fruit, and it portends great benefits for the biosphere. One obvious consequence is greater crop productivity; and many researchers acknowledge the yield-enhancing benefits of the historical and still-ongoing rise in the air’s CO2 content on past, present and future crop yields. According to one recent study, rising CO2 concentrations boosted the value of global crop production over the past 50 years by a staggering $3.2 trillion. An additional $9.8 trillion in monetary gains are estimated to accrue in the future in response to the projected rise in atmospheric CO2 between now and 2050.


The second major benefit is increased water use efficiency. Plants exposed to elevated levels of atmospheric CO2 generally do not open their leaf stomatal pores as wide as they do at lower CO2 concentrations. The result is a reduction in most plants’ rates of water loss by transpiration. The amount of carbon (biomass) they gain per unit of water lost – or water-use efficiency – therefore typically rises for a doubling of CO2 on the order of 70 to 100 percent. And as a result, at higher atmospheric CO2 concentrations numerous studies show plants need less water to produce the same or an even greater amount of biomass than they do at lower CO2 concentrations. One implication of this benefit is that plants will be able to grow and reproduce in locations where it was previously too dry for them to even exist; and they may therefore win back lands previously lost to desertification.


The third major benefit of atmospheric CO2 enrichment is an amelioration of environmental stresses and resource limitations. Higher levels of CO2 tend to help reduce detrimental growth effects of high soil salinity, high air temperature, low light intensity and low levels of soil fertility. They also reduce the severity of low temperature stress, oxidative stress and the stress of herbivory. What is more, the relative percentage growth enhancement produced by an increase in the air’s CO2 content is often greater when comparing plants growing under stressful and resource-limited conditions than when growing conditions are ideal.

Altogether, with the plant productivity gains that result from the aerial fertilization effect of the ongoing rise in atmospheric CO2, plus its transpiration-reducing effect that boosts plant water use efficiency along with its stress-alleviating effect that lessens the negative growth impacts of resource limitations and environmental constraints, the world’s vegetation possesses an ideal mix of abilities to reap a tremendous benefit in the years and decades to come. And based on a multitude of observations, the future is now. As evidence from around the globe indicates, the terrestrial biosphere is presently experiencing a great planetary surge in growth, likely due in large measure to the approximate 40 percent increase in atmospheric CO2 that has occurred since the beginning of the Industrial Revolution.

Real-world evidence of such is apparent in the long-term observation of forests. Tree growth at locations all around the globe over the past two centuries, for example, reveals trends that are not consistent with the usual climatic variables attributable to growth stimulation, such as temperature or precipitation. In these instances, researchers acknowledge the steady influence of rising atmospheric CO2 concentrations on growth trends, which trends are often manifested as increases in both the density and aerial coverage of woody species.

Other evidence of a CO2-induced stimulation of vegetation in recent years is seen in grassland and desert ecosystems, as well as for the world as a whole. With respect to all land plants, for example, satellite-based studies reveal net terrestrial primary productivity has increased by six to 13 percent since the 1980s. Other research shows the annual global carbon uptake has doubled from 2.4 ± 0.8 billion tons in 1960 to 5.0 ± 0.9 billion tons in 2010. What makes these observations appear even more astonishing, however, is the fact that they occurred in spite of the many recorded assaults of both man and nature on planetary vegetation over this time period, including fires, disease, pest outbreaks, deforestation and climatic changes in temperature and precipitation. That the biosphere experienced any productivity improvement, let alone a doubling, is truly amazing; and it demonstrates, in part, the powerful impact atmospheric CO2 enrichment is exerting on global vegetation.

As a society, it is high time for us to recognize and embrace the truth. Contrary to misguided assertions, political correctness and government edicts, carbon dioxide is not a pollutant. It’s a colorless, odorless, tasteless atmospheric gas that is essential to nearly all life on earth. Please remember that, especially the next time you are quizzed about its virtues.
