global warming

Main temperature database used by IPCC found to contain multiple errors

An audit of the HadCRUT4 dataset, the primary global temperature database used by the Intergovernmental Panel on Climate Change (IPCC) has found multiple errors.

HadCRUT4 is also the dataset at the center of “ClimateGate” from 2009, managed by the Climate Research Unit (CRU) at East Anglia University.

The paper, An Audit of the Creation and Content of the HadCRUT4 Temperature Dataset by John McLean (PhD), was first published as a PhD thesis and now as a book. Get the book for $8 here. Read the original thesis here (free download).

The audit found more than 70 areas of concern about data quality and accuracy.

Australian researcher John McLean says that HadCRUT4 is far too sloppy to be taken seriously even by climate scientists, let alone a body as influential as the IPCC or by the governments of the world.

Main points:

The Hadley data is one of the most cited, most important databases for climate modeling, and thus for policies involving billions of dollars.

McLean found freakishly improbable data, and systematic adjustment errors, large gaps where there is no data, location errors, Fahrenheit temperatures reported as Celsius, and spelling errors.

[The improper transposition of Fahrenheit temperatures to Celsius is serious. Fahrenheit 40 is a cool temperature but Celsius 40 is equivalent to 104 Fahrenheit. This erroneous transposition is real “man-made global warming.”]

Almost no quality control checks have been done: outliers that are obvious mistakes have not been corrected. For instance, one town in Columbia spent three months in 1978 at an average daily temperature of over 80 degrees C (176 F). One town in Romania stepped out from summer in 1953 straight into a month of Spring at minus 46°C. These are supposedly “average” temperatures for a full month at a time. St Kitts, a Caribbean island, was recorded at 0°C for a whole month, and twice!

Temperatures for the entire Southern Hemisphere in 1850 and for the next three years are calculated from just one site in Indonesia and some random ships.

Sea surface temperatures represent 70% of the Earth’s surface, but some measurements come from ships which are logged at locations 100km inland. Others are in harbors which are hardly representative of the open ocean.

When a thermometer is relocated to a new site, the adjustment assumes that the old site was always built up and “heated” by concrete and buildings. In reality, the artificial warming probably crept in slowly. By correcting for buildings that likely didn’t exist in 1880, old records are artificially cooled. Adjustments for a few site changes can create a whole century of artificial warming trends.

Details of the worst outliers:

For April, June and July of 1978 Apto Uto, Colombia had an average monthly temperature of 81.5°C, 83.4°C and 83.4°C respectively. (178 to 182 Fahrenheit)

The monthly mean temperature in September 1953 at Paltinis, Romania is reported as -46.4 °C (in other years the September average was about 11.5°C).

At Golden Rock Airport, on the island of St Kitts in the Caribbean, mean monthly temperatures for December in 1981 and 1984 are reported as 0.0°C. But from 1971 to 1990 the average in all the other years was 26.0°C.

Bad data and bad modeling assumptions make IPCC temperature simulations diverge widely from really. That’s why we should not believe the IPCC when they cry “wolf” and say it’s the end of the world unless we give them billions of dollars and get rid of fossil fuels.

The primary conclusion of the audit (as noted by Anthony Watts) is that the dataset shows exaggerated warming and that global averages are far less certain than have been claimed.

One implication of the audit is that climate models have been tuned to match incorrect data, which would render incorrect their predictions of future temperatures and estimates of the human influence of temperatures.

Another implication is that the proposal that the Paris Climate Agreement adopt 1850-1899 averages as “indicative” of pre-industrial temperatures is fatally flawed. During that period global coverage is low – it averages 30% across that time – and many land-based temperatures are very likely to be excessively adjusted and therefore incorrect.

 

Why is it that a PhD student working from home can find mistakes that the British Met Office, a £226 million institute with 2,100 employees, could not. Significantly, the Met Office, in a statement, said they do not disagree with any of his claims.

Maybe, as President Dwight D. Eisenhower said in his farewell address:

Today, the solitary inventor, tinkering in his shop, has been overshadowed by task forces of scientists in laboratories and testing fields. In the same fashion, the free university, historically the fountainhead of free ideas and scientific discovery, has experienced a revolution in the conduct of research. Partly because of the huge costs involved, a government contract becomes virtually a substitute for intellectual curiosity. For every old blackboard there are now hundreds of new electronic computers.

The prospect of domination of the nation’s scholars by Federal employment, project allocations, and the power of money is ever present – and is gravely to be regarded.

Yet, in holding scientific research and discovery in respect, as we should, we must also be alert to the equal and opposite danger that public policy could itself become the captive of a scientific-technological elite.

Harvard study shows that wind power could cause more warming than coal

As reported by James Temple in the MIT Technology Review:

A new study by a pair of Harvard researchers finds that a high amount of wind power could mean more climate warming, at least regionally and in the immediate decades ahead. The paper raises serious questions about just how much the United States or other nations should look to wind power to clean up electricity systems.

The study, published in the journal Joule, found that if wind power supplied all US electricity demands, it would warm the surface of the continental United States by 0.24 °C. That could significantly exceed the reduction in US warming achieved by decarbonizing the nation’s electricity sector this century, which would be around 0.1 °C.

“If your perspective is the next 10 years, wind power actually has—in some respects—more climate impact than coal or gas,” coauthor David Keith, a professor of applied physics and public policy at Harvard, said in a statement. “If your perspective is the next thousand years, then wind power is enormously cleaner than coal or gas.”

The core problem is that wind turbines generate electricity by extracting energy out of the air, slowing down wind and otherwise altering “the exchange of heat, moisture, and momentum between the surface and the atmosphere,” the study explains. That can produce some level of warming. The new research suggests we can’t put too many turbines to close together or the whole group become far less efficient. That means we need 5 – 20 times as much land as previously thought (at least as thought by academics) Read more

Testing Basic Assumptions of the CO2-induced Global Warming Hypothesis

This is a repost of a paper review by CO2Science.org which shows there is no correlation between temperature and carbon dioxide.  See the post in its original here:

http://www.co2science.org/articles/V21/sep/a9.php 

Paper Reviewed
Liu, X. and Chen, J. 2017. CO2 seasonal variation and global change: Test global warming from another point of view. Sciences in Cold and Arid Regions 9: 0046-0053, DOI: 103724/SP.J.1226.2017.00046.

In this posting we review the work of two Chinese scientists, Liu and Chen (2017), who performed a significant and thorough investigation of the relationship between atmospheric carbon dioxide and temperature, challenging the fundamental argument of the IPCC that rising atmospheric CO2 is causing rising global temperature. For the past year and a half a printout of this article has remained buried under a pile of papers on a desk in our office intended for review and posting on CO2Science. Now, after a long wait (and overdue cleaning of our office), this important work gets the attention it deserves.

Setting the stage for their work, Liu and Chen note that “the core theory of CO2-caused global warming proposed by the IPCC is based on three assumptions: (1) The Earth acts like a greenhouse, and the greenhouse effect of increasing CO2 is capable of raising temperature. (2) The available instrumental temperature records over the last century accurately reflect global temperature trends. (3) The rising atmospheric CO2 is the result of the increasing consumption of fossil fuel.” And they go on to say that “the conclusions by IPCC are logical deductions that should be tested and proven (or challenged) by facts.”

As their contribution to science, the two scientists thus proceed to present just such a challenge by examining the relationship between temperature and CO2 using data from Mauna Loa, Hawaii and other observing stations across the globe. Their analyses revealed several important findings, which are discussed in detail below, often using direct quotes from the authors’ paper.

Finding #1. “The monthly variations in CO2 and temperature at Mauna Loa, Hawaii, do not correlate with each other (R2 = 0.0355). From 1958-2013, CO2 rose while temperature remained flat. Hence, we seriously question whether CO2 is the driving force behind temperature variation.”

Finding #2. “Both the instrumental CO2 and temperature records at the Mauna Loa, Hawaii, station show seasonal rises and falls. But there is a 6-month difference in seasonal CO2 and temperature fluctuations between the records in the Northern Hemisphere and the Southern Hemisphere. As we know, the reversal of seasons is determined by the changes in solar radiation. Thus, it is most likely that these seasonal rises and falls of both CO2 and temperature are driven by changes in solar radiation.”

Finding #3. “By studying the monthly relationship between CO2 and temperature over several decades, we established a theoretical transfer function between CO2 and temperature. Using this function, the rise of 81.86 [ppm] in CO2 at Mauna Loa, Hawaii, between 1958 and 2012 should have resulted in a 72.86 °C rise in temperature, when in fact the temperature only rose -0.62 °C. Thus, we submit that changes in atmospheric CO2 may not be the cause of global temperature changes.”

Finding #4. “In contrast to [the] IPCC’s suggestion that global temperature rose 0.85 °C over the last century, from 1958 to 2012, temperatures at Mauna Loa, Hawaii, did not rise over this period. Mauna Loa is far from cities, where temperature variations are most affected by the urban heat island effect. Independent studies in North America, Europe, Australia, and China have shown that the urban heat island effect could lead to recorded temperature rises <1 °C. Thus, we suggest that the IPCC’s 0.85 °C temperature rise over the last century could be sufficiently explained by the urban island heat effect.”

Finding #5. “The global monthly mean temperature produced by GISS (2013) shows a high correlation with Hawaii CO2 (R2 = 0.7655). However, R2 = 0.024 is obtained by 188 selected records from individual stations around the world. This test indicated global monthly mean temperature showing high correlation with Hawaii CO2 (R2 = 0.7655) was inappropriately corrected and calculated during data process[ing].”

In light of all the important findings listed above, Liu and Chen conclude their paper by writing “an untrue picture is therefore created [based on global monthly mean temperature], that CO2 emission by human activity drives global warming.”

A summary of climate change principles and state of the science – a rebuttal of climate alarmism

This post collects several past articles which review the science and bring together some main points on the state of the climate debate. These points show that the politically correct, carbon dioxide driven meme is wrong. Readers can use these articles to counter climate alarmist. Read each article for more details.

Climate change in perspective

Climate change is a major issue of our times. Concern is affecting environmental, energy, and economic policy decisions. Many politicians are under the mistaken belief that legislation and regulation can significantly control our climate to forestall any deviation from “normal” and save us from a perceived crisis. This post is intended as a primer for politicians so they can cut through the hype and compare real observational data against the flawed model prognostications.

The data show that the current warming is not unusual, but part of a natural cycle; that greenhouse gases, other than water vapor, are not significant drivers of climate; that human emissions of carbon dioxide are insignificant when compared to natural emissions of greenhouse gases; and that many predictions by climate modelers and hyped by the media are simply wrong.

 

A simple question for climate alarmists – where is the evidence

“What physical evidence supports the contention that carbon dioxide emissions from burning fossil fuels are the principal cause of global warming since 1970?”

(Remember back in the 1970s, climate scientists and media were predicting a return to an “ice age.”)

I have posed that question to five “climate scientist” professors at the University of Arizona who claim that our carbon dioxide emissions are the principal cause of dangerous global warming. Yet, when asked the question, none could cite any supporting physical evidence.

 

Carbon dioxide is necessary for life on Earth

Rather than being a “pollutant.” Carbon dioxide is necessary for life on Earth as we know it. 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.

 

Carbon Dioxide and the Greenhouse Effect

The “greenhouse effect,” very simplified, is this: solar radiation penetrates the atmosphere and warms the surface of the earth. The earth’s surface radiates thermal energy (infrared radiation) back into space. Some of this radiation is absorbed and re-radiated back to the surface and into space by clouds, water vapor, methane, carbon dioxide, and other gases. Water vapor is the principle greenhouse gas; the others are minor players. It is claimed that without the greenhouse effect the planet would be an iceball, about 34∘C colder than it is.* The term “greenhouse effect” with respect to the atmosphere is an unfortunate usage because it is misleading. The interior of a real greenhouse (or your automobile parked with windows closed and left in the sun) heats up because there is a physical barrier to convective heat loss. There is no such physical barrier in the atmosphere.*There is an alternate hypothesis:

 

What keeps Earth warm – the greenhouse effect or something else?

Scottish physicist James Clerk Maxwell proposed in his 1871 book “Theory of Heat” that the temperature of a planet depends only on gravity, mass of the atmosphere, and heat capacity of the atmosphere. Temperature is independent of atmosphere composition. Greenhouse gases have nothing to do with it. Many publications since, have expounded on Maxwell’s theory and have shown that it applies to all planets in the Solar System.

The Grand Canyon of Arizona provides a practical demonstration of this principle.

 

Evidence that CO2 emissions do not intensify the greenhouse effect

The U.S. government’s National Climate Assessment report and the UN IPCC both claim that human carbon dioxide emissions are “intensifying” the greenhouse effect and causing global warming. The carbon dioxide driven global warming meme makes four specific predictions. Physical evidence shows that all four of these predictions are wrong.

“It doesn’t matter how beautiful your theory is; it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong.” – Richard Feynmann

 

An examination of the relationship between temperature and carbon dioxide

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.

 

How much global warming is dangerous?

The United Nation’s IPCC and other climate alarmists say all hell will break loose if the global temperature rises more than an additional 2º C (3.6ºF). That number, by the way, is purely arbitrary with no basis in science. It also ignores Earth’s geologic history which shows that for most of the time global temperatures have been much warmer than now. Let’s look back at a time when global temperatures are estimated to have been as much as 34ºF warmer than they are now. Hell didn’t break loose then.

 

Effects of global warming on humans

The EPA’s “endangerment finding” classified carbon dioxide as a pollutant and claimed that global warming will have adverse effects on human health. Real research says the opposite: cold is deadlier. The scientific evidence shows that warming is good for health.

 

Geology is responsible for some phenomena blamed on global warming

Melting of the Greenland and West Antarctic ice sheets have been blamed on global warming, but both have a geologic origin. The “Blob” a recent warm ocean area off the Oregon coast, responsible in part for the hot weather and drought in California, has been blamed on global warming, but that too may have a geologic cause.

 

The 97 percent consensus for human caused climate change debunked again

It has been claimed that 97% of climate scientists say humans are causing most of the global warming. An examination of the numbers and how those numbers have been reached show that only 8.2% of scientists polled explicitly endorse carbon dioxide as the principal driver.

Conclusion:

The basic conclusion of this review is that carbon dioxide has little effect on climate and all attempts to control carbon dioxide will be a futile and expensive exercise to no end. All the dire predictions are based on flawed computer models. Carbon dioxide is a phantom menace.

 

“The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary.” – H. L. Mencken

Nitrogen in rocks identified as major plant fertilizer not considered by climate models

Organic nitrogen compounds such as ammonia (NH3) act as plant fertilizers. Robust plant growth consumes more atmospheric carbon dioxide during the process of photosynthesis. However, atmospheric nitrogen (N2) is relatively inert. It is converted to organic nitrogen compounds by bacteria in the top soil layers. (See nitrogen fixation) Climate models have assumed that the atmosphere is the only source of nitrogen and have therefore underestimated its fertilization effect and also underestimated the capability of plants to remove carbon dioxide from the atmosphere. New studies show that much nitrogen comes from rocks, some already in useable organic form. Weathering of rocks releases this organic nitrogen.

“A considerable amount of the nitrogen in igneous and sedimentary rocks exists as ammonium ions held within the lattice structures of silicate minerals. In sedimentary rocks, the ammonium is held by secondary silicate minerals; in igneous rocks, the ammonium is contained largely within potassium-bearing primary minerals. Analyses indicated that most of the nitrogen in igneous rocks, and from one-tenth to two-thirds of that in sedimentary rocks (shales) occurred as fixed ammonium.” (Source)

Nitrate deposits in arid and semi-arid regions provide another source of nitrogen.

“Nitrogen bearing rocks are globally distributed and comprise a potentially large pool of nitrogen in nutrient cycling that is frequently neglected because of a lack of routine analytical methods for quantification. Nitrogen in rock originates as organically bound nitrogen associated with sediment, or in thermal waters representing a mixture of sedimentary, mantle, and meteoric sources of nitrogen.” (Source)

A new study, reported by Science Daily, concerns research conducted by University of California – Davis published April 6, 2018.

“For centuries, the prevailing science has indicated that all of the nitrogen on Earth available to plants comes from the atmosphere. But a study from the University of California, Davis, indicates that more than a quarter comes from Earth’s bedrock.”

“The discovery could greatly improve climate change projections, which rely on understanding the carbon cycle. This newly identified source of nitrogen could also feed the carbon cycle on land, allowing ecosystems to pull more emissions out of the atmosphere, the authors said.”

“Geology might have a huge control over which systems can take up carbon dioxide and which ones don’t.”

“While there were hints that plants could use rock-derived nitrogen, this discovery shatters the paradigm that the ultimate source of available nitrogen is the atmosphere. Nitrogen is both the most important limiting nutrient on Earth and a dangerous pollutant, so it is important to understand the natural controls on its supply and demand. Humanity currently depends on atmospheric nitrogen to produce enough fertilizer to maintain world food supply. A discovery of this magnitude will open up a new era of research on this essential nutrient.”

Looks like “climate science” is still not settled. For instance, a 2003 study published in the same Science journal claimed, “there will not be enough nitrogen available to sustain the high carbon uptake scenarios.” Investor’s Business Daily opines: “with more nitrogen available, plant life might be able to absorb more CO2 than climate scientists have been estimating, which means the planet won’t warm as much, despite mankind’s pumping CO2 into the atmosphere.”

A Simple Question for Climate Alarmists

Tuvalu and other Pacific islands resist sea level rise and add land area

Climate alarmists have long been predicting that global warming induced sea level rise would make low-lying Pacific islands disappear and cause thousands of “climate refugees” to seek new homes. Here are some examples:

Smithsonian.com, August, 2004: Will Tuvalu Disappear Beneath the Sea? Global warming threatens to swamp a small island nation.

Mother Jones, December, 2009: What Happens When Your Country Drowns?

Washington Post, August, 2014: Has the era of the ‘climate change refugee’ begun?

Bloomberg, November, 2017: A Tiny Island Prepares the World for a Climate Refugee Crisis.

The University of Arizona has been complicit in this hype; see my Wryheat post: University of Arizona dances with sea level.

These alarmist claims have not come to pass because of the geologic processes that build these islands.

A new paper published in Nature Communications on Feb. 9, 2018, shows that despite sea level rise, most islands are increasing in land area.

A University of Auckland study (Patterns of island change and persistence offer alternate adaptation pathways for atoll nations, Paul S. Kench, Murray R. Ford & Susan D. Owen) examined changes in the geography of Tuvalu’s nine atolls and 101 reef islands between 1971 and 2014, using aerial photographs and satellite imagery. The paper claims that local sea level has risen at twice the global average (~3.90 + 0.4 mm.yr-1). That translates to about six inches over the 43-year period. However, the study found eight of the atolls and almost three-quarters of the islands grew during the study period, increasing Tuvalu’s total land area by 2.9 percent, even though sea levels in the country rose at twice the global average. (Read Full paper in Nature).

Here is figure 3 from that paper followed by its caption:

Caption for Tuvalu fig 3 (ha = hectares): Examples of island change and dynamics in Tuvalu from 1971 to 2014.

A Nanumaga reef platform island (301 ha) increased in area 4.7 ha (1.6%) and remained stable on its reef platform.

B Fangaia island (22.4 ha), Nukulaelae atoll, increased in area 3.1 ha (13.7%) and remained stable on reef rim.

C Fenualango island (14.1 ha), Nukulaelae atoll rim, increased in area 2.3 ha (16%). Note smaller island on left Teafuafatu (0.29 ha), which reduced in area 0.15 ha (49%) and had significant lagoonward movement.

D Two smaller reef islands on Nukulaelae reef rim. Tapuaelani island, (0.19 ha) top left, increased in area 0.21 ha (113%) and migrated lagoonward. Kalilaia island, (0.52 ha) bottom right, reduced in area 0.45 ha (85%) migrating substantially lagoonward.

E Teafuone island (1.37 ha) Nukufetau atoll, increased in area 0.04 ha (3%). Note lateral migration of island along reef platform. Yellow lines represent the 1971 shoreline, blue lines represent the 1984 shoreline, green lines represent the 2006 shoreline and red lines represent the 2014 shoreline.

 

The reason that these islands are gaining area is that as the sea rises, coral reefs grow higher and trap coral debris and sand to build up the island. The science of coral reef atolls is not new. This process was first described by Charles Darwin in 1842: The structure and distribution of coral reefs. Being the first part of the geology of the voyage of the Beagle, under the command of Capt. Fitzroy, R.N. during the years 1832 to 1836. London: Smith Elder and Co. (Link to Darwin’s full description).

This figure from Darwin’s paper shows that coral atolls originate around a volcanic island or seamount. As sea level rises (or land sinks) the corals grow to remain in shallow water and the coral debris and sand cause an atoll island to form. That the corals were able to overcome a recent six-inch rise in sea level may not seem very much, but remember that these islands have been around a long time and dealt with a 400-foot rise in sea level since the depths of the last glacial epoch.

The findings of the new paper cited above support previous studies. For instance:

Kench et al., 2015, Coral islands defy sea-level rise over the past century: Records from a central Pacific atoll, Geological Society of America, in Geology Magazine, March 2015. (Source)

“Funafuti Atoll, in the tropical Pacific Ocean, has experienced some of the highest rates of sea-level rise (~5.1 + 0.7 mm/yr), totaling ~0.30 + 0.04 m over the past 60 yr. We analyzed six time slices of shoreline position over the past 118 yr at 29 islands of Funafuti Atoll to determine their physical response to recent sea-level rise. Despite the magnitude of this rise, no islands have been lost, the majority have enlarged, and there has been a 7.3% increase in net island area over the past century (A.D. 1897–2013). There is no evidence of heightened erosion over the past half-century as sea-level rise accelerated. Reef islands in Funafuti continually adjust their size, shape, and position in response to variations in boundary conditions, including storms, sediment supply, as well as sea level. Results suggest a more optimistic prognosis for the habitability of atoll nations and demonstrate the importance of resolving recent rates and styles of island change to inform adaptation strategies.”

Climate Craziness, Politics, and Hypocrisy

In my opinion, the greatest danger we face from global warming is that politicians think they can stop it. Politicians decree that we must reduce carbon dioxide emissions from use of fossil fuels even though there is no physical evidence that those emissions play a significant role is controlling global temperature. (See: Evidence that CO2 emissions do not intensify the greenhouse effect)

The policy of reducing CO2 emissions is costing billions, even trillions, of dollars that could be put to better use. For instance, Germany will have to spend more than 1 trillion euros ($1.2 trillion) to meet even the lower end of the European Union’s 2050 target to reduce carbon dioxide emissions, according to a draft of a study commissioned by the BDI German industry group. (Source).

Several counties and municipalities in California as well as New York City have filed lawsuits against energy companies. These suits are seeking to force oil and gas companies to pay reparations for severe weather and infrastructure advancements to guard against future storms and rising sea levels. Read more However, as noted by Valerie Richardson in The Washington Times, the risks posed by human-caused climate change were apparently alarming enough to prompt seven California municipalities last year to sue ExxonMobil, but not serious enough to disclose in full to their investors. “Notwithstanding their claims of imminent, allegedly near-certain harm, none of the municipalities disclosed to investors such risks in their respective bond offerings, which collectively netted over $8 billion for these local governments over the last 27 years,” said ExxonMobil in its petition in Texas District Court. Read more.

Back in the year 2000, Dr David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia, predicted that within a few years winter snowfall will become “a very rare and exciting event. Children just aren’t going to know what snow is. Snowfalls are now just a thing of the past.” (Source) Residents of the northeast U.S. would disagree due to the very cold weather and snowfalls this winter.

Also, at the World Economic Forum in Davos, Switzerland (January, 2018), climate activists set up a base camp to educate world leaders about man-made global warming. Mother Nature didn’t cooperate, however, as the “Gore Effect” kicked in and dumped about six feet of snow on their little stunt during the last six days. The weather at Davos did not deter the arrival of 1,000 private jets owned or chartered by elites who lecture the rest of us about limiting our “carbon footprint.” The hosting organization for the Davos forum has a formal sustainability policy that vows to “limit our environmental impact” and addresses such issues as climate change and deforestation.

Just plain crazy:

Researchers at The University of Manchester have carried out the first ever study looking at the carbon footprint of sandwiches, both home-made and pre-packaged. They considered the whole life cycle of sandwiches, including the production of ingredients, sandwiches and their packaging, as well as food waste discarded at home and elsewhere in the supply chain. Of the recipes considered, the most carbon-intensive variety is a ready-made ‘all-day breakfast’ sandwich which includes egg, bacon and sausage. Read more

Researchers at the University of Arizona set out to learn more about how people’s perception of the threat of global climate change affects their mental health. They found that while some people have little anxiety about the Earth’s changing climate, others are experiencing high levels of stress, and even depression, based on their perception of the threat of global climate change. Read more

Alarmist scientists have found a terrifying new ‘climate change’ threat: mutant transgender turtles.

“Climategate” comes back to bite the University of Arizona

“The University of Arizona has been ordered to surrender emails by two UA scientists that a group claims will help prove that theories about human-caused climate change are false and part of a conspiracy.” (Arizona Daily Star) The professors involved are Malcolm Hughes, who is still with the UA, and Jonathan Overpeck, who left earlier this year.

The backstory begins in 2009:

In 2009, it was revealed that someone hacked in to the files of the Climatic Research Unit (CRU) based at the University of East Anglia, in England. The CRU has been a major proponent of anthropogenic global warming and a principal in report preparation for the Intergovernmental Panel on Climate Change (IPCC).

More than 1,000 internal emails and several reports from CRU have been posted on the internet and the blogosphere had gone wild with the implications of the revealed messages. Dr. Phil Jones, head of CRU, confirmed that his organization has been hacked and that the emails are accurate. This disclosure did not include any Emails at other institutions such as Penn State or the University of Arizona.

The emails reveal a concerted effort on the part of a small group of scientists to manipulate data, suppress dissent, and foil the dissemination of the information by “losing” data and skirting Britain’s Freedom of Information Act. The emails reveal that the contention of dangerous human-induced global warming is not supported by the data, that those supporting that contention knew it, and sought to control the discussion so as to hide the unreliable nature of what they were claiming.

Part of the controversy involved the infamous “hock stick” graph devised by Michael Mann of Penn State and subsequently adopted by the IPCC.

In the “battle of the graphs” the bottom panel shows temperatures based on proxy data and measurements. It shows that the Medieval Warm Period of 1,000 years ago was much warmer than now. Mann’s hockey stick did away with the Medieval Warm Period and showed only a large spike of recent warming – hence the name “hockey stick”. The “hockey stick” made its debut in the journal Geophysical Research Letters in 1999 in a paper by Michael Mann, Raymond Bradley, and Malcolm Hughes that built upon a 1998 paper by the same authors in the journal Nature which detailed the methodology for creating a proxy temperature reconstruction.

There are problems with the Hockey Stick according to Canadian researchers Steve McIntyre and Ross McKitrick. “The first mistake made by Mann et al. and copied by the UN in 2001 lay in the choice of proxy data. The UN’s 1996 report had recommended against reliance upon bristlecone pines as proxies for reconstructing temperature because 20th-century carbon-dioxide fertilization accelerated annual growth and caused a false appearance of exceptional recent warming. Notwithstanding the warning against reliance upon bristlecones in UN 1996, Mann et al. had relied chiefly upon a series of bristlecone-pine datasets for their reconstruction of medieval temperatures. Worse, their statistical model had given the bristlecone-pine data sets 390 times more prominence than the other datasets they had used.

Furthermore, the statistical algorithms in Mann et al. where shown to be flawed. McIntyre ran the Mann’s algorithm 10,000 times, having replaced all palaeoclimatological data with randomly-generated, electronic “red noise”. They found that, even with this entirely random data, altogether unconnected with the temperature record, the model nearly always constructed a “hockey stick” curve similar to that in the UN’s 2001 report.” (See their detailed report)

Mann had another problem. Their proxy data began to rise, but then took a plunge into cooler temperatures. They hid this decline by truncating the proxy data and substituting rising measured temperatures without telling anyone. This became known as “Mike’s Nature Trick”. (Read more)

One other incident: In my article A Simple Question for Climate Alarmists I posed this question: “What physical evidence supports the contention that carbon dioxide emissions from burning fossil fuels are the principal cause of global warming since 1970?” In a public forum, I had the opportunity to pose this question to then UofA professor Jonathan Overpeck. He could not cite any supporting physical evidence.

 

Effects of global warming on human health

The EPA’s “endangerment finding” classified carbon dioxide as a pollutant and claimed that global warming will have adverse effects on human health. Real research says the opposite: cold is deadlier.  The scientific evidence shows that warming is good for health. This is discussed in detail in chapter 7 of Climate Change Reconsidered II: Biological Impacts published by the Heartland Institute. See links to the entire publication at: http://climatechangereconsidered.org/climate-change-reconsidered-ii-biological-impacts/

Here are the key findings based on extensive review of the scientific literature:

• Warmer temperatures lead to a net decrease in temperature-related mortality, including deaths associated with cardiovascular disease, respiratory disease, and strokes. The evidence of this benefit comes from research conducted in every major country of the world.

• In the United States the average person who died because of cold temperature exposure lost in excess of 10 years of potential life, whereas the average person who died because of hot temperature exposure likely lost no more than a few days or weeks of life.

• Some 4,600 deaths are delayed each year as people in the U.S. move from cold northeastern states to warm southwestern states. Between 3 and 7% of the gains in longevity experienced by the U.S. population over the past three decades is due simply to people moving to warmer states.

• Cold-related deaths are far more numerous than heat-related deaths in the United States, Europe, and almost all countries outside the tropics. Coronary and cerebral thrombosis account for about half of all cold-related mortality.

• Global warming is reducing the incidence of cardiovascular diseases related to low temperatures and wintry weather by a much greater degree than it increases the incidence of cardiovascular diseases associated with high temperatures and summer heat waves.

• The adverse health impacts of cold temperatures, especially with respect to respiratory health, are more significant than those of high temperatures in many parts of the world, including Spain, Canada, Shanghai, and Taiwan. In the subtropical island of Taiwan, for example, researchers found low minimum temperatures were the strongest risk factor associated with outpatient visits for respiratory diseases.

• A vast body of scientific examination and research contradict the claim that malaria will expand across the globe and intensify as a result of CO2-induced warming.

• Concerns over large increases in vector-borne diseases such as dengue as a result of rising temperatures are unfounded and unsupported by the scientific literature, as climatic indices are poor predictors for dengue disease.

• While climatic factors largely determine the geographical distribution of ticks, temperature and climate change are not among the significant factors determining the incidence of tick-borne diseases.

• The ongoing rise in the air’s CO2 content is not only raising the productivity of Earth’s common food plants but also significantly increasing the quantity and potency of the many health-promoting substances found in their tissues, which are the ultimate sources of sustenance for essentially all animals and humans.

• Atmospheric CO2 enrichment positively impacts the production of numerous health-promoting substances found in medicinal or “health food” plants, and this phenomenon may have contributed to the increase in human life span that has occurred over the past century or so.

• There appears to be little reason to expect any significant CO2-induced increases in human health-harming substances produced by plants as the atmosphere’s CO2 concentration continues to rise.

Fourth National Climate Assessment is junk science

Fourth National Climate Assessment is junk science

The U.S. Global Change Research Program (USGCRP) has just released the final version of its Fourth National Climate Assessment report, one that many were claiming that the Trump administration would suppress because, like its predecessors, it is mainly a political document rather than a true scientific assessment . You can read the full 477-page report here: https://science2017.globalchange.gov/

The main conclusion is: “This assessment concludes, based on extensive evidence, that it is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the mid-20th century.”

The “extensive evidence” is based entirely on climate modeling rather than on observations. The results produced by models diverge widely from reality. The new report makes the same claims and invokes the same junk science as the previous 2014 report which I analyzed here: National Climate Assessment Lacks Physical Evidence.

As an example of unfounded claims made in the new report we see this statement in the executive summary: “Heatwaves have become more frequent in the United States since the 1960s, while extreme cold temperatures and cold waves are less frequent.”

But plots from the EPA and NOAA show that the most intense heat waves occurred in the 1930s.

 

Another example:

Claim in the report: “The incidence of large forest fires in the western United States and Alaska has increased since the early 1980s and is projected to further increase in those regions as the climate changes, with profound changes to regional ecosystems.” This statement is technically correct but it represents cherry-picking and lying by omission.

The National Interagency Fire Center has a table listing the number of fires and acreage burned from 1960 through 2016 (see: https://www.nifc.gov/fireInfo/fireInfo_stats_totalFires.html ).

We see from the table that there were 18,229 fires reported in 1983 which increased to 67,743 fires reported in 2016. What the report doesn’t mention is that the number of fires from 1960 to 1982 were all in the six figure range, e.g., in 1960 there were 103,387 fires and in 1981 there were 249,370 fires. The number dropped to 174,755 fires in 1982.

Fire frequency does not necessarily increase with warming. In many parts of the world, fire frequency decreases with warming. See my post “Wildfires And Warming – relationship not so clear.”

A third example of unfounded claims:

Section 2.6.1 of the report discusses the “greenhouse effect.” They claim: “As increasing GHG [greenhouse gases] concentrations warm the atmosphere, tropospheric water vapor concentrations increase, thereby amplifying the warming effect.” Climate models depend on this assumption. But NOAA’s own data show that global humidity has been decreasing with warming.

Comments by others:

Theoretical physicist Steve Koonin has an op-ed in the Wall Street Journal entitled “A Deceptive New Report on Climate.”

Koonin was undersecretary of energy for science during President Obama’s first term and is director of the Center for Urban Science and Progress at New York University. The WSJ article is pay-walled but you can read extensive excerpts here.

Among his comments:

One notable example of alarm-raising is the description of sea-level rise, one of the greatest climate concerns. The report ominously notes that while global sea level rose an average 0.05 inch a year during most of the 20th century, it has risen at about twice that rate since 1993. But it fails to mention that the rate fluctuated by comparable amounts several times during the 20th century. The same research papers the report cites show that recent rates are statistically indistinguishable from peak rates earlier in the 20th century, when human influences on the climate were much smaller. The report thus misleads by omission.

Note: The rate of sea level rise and fall tends to be cyclical on decadal and bi-decadal periods. See my article: The Sea Level Scam.

Koonin also comments on heat waves: The report’s executive summary declares that U.S. heat waves have become more common since the mid-1960s, although acknowledging the 1930s Dust Bowl as the peak period for extreme heat. Yet buried deep in the report is a figure [6.3] showing that heat waves are no more frequent today than in 1900.

Comments by Dr. Patrick J. Michaels, director of the Center for the Study of Science at the Cato Institute, past president of the American Association of State Climatologists, and former program chair for the Committee on Applied Climatology of the American Meteorological Society. He was a research professor of Environmental Sciences at University of Virginia for 30 years. Read full post “What You Won’t Find in the New National Climate Assessment.”

Under the U.S. Global Change Research Act of 1990, the federal government has been charged with producing large National Climate Assessments (NCA), and today the most recent iteration has arrived. It is typical of these sorts of documents–much about how the future of mankind is doomed to suffer through increasingly erratic weather and other tribulations. It’s also missing a few tidbits of information that convincingly argue that everything in it with regard to upcoming 21st century climate needs to be taken with a mountain of salt.

The projections in the NCA are all based upon climate models. If there is something big that is systematically wrong with them, then the projections aren’t worth making or believing.

The report does not tell you that:

1) Climate model predictions of global temperature diverge widely from observations.

2) No hot spot over tropics: The models predict that there should have been a huge “hot spot” over the entire tropics, which is a bit less than 40% of the globe’s surface. Halfway up through the atmosphere (by pressure), or at 500 hPa, the predicted warming is also twice what is being observed, and further up, the prediction is for seven times more warming than is being observed.

The importance of this is paramount. The vertical distribution of temperature in the tropics is central to the formation of precipitation.

Missing the tropical hot spot provokes an additional cascade of errors. A vast amount of the moisture that forms precipitation here originates in the tropics. Getting that wrong trashes the precipitation forecast, with additional downstream consequences, this time for temperature.

When the sun shines over a wet surface, the vast majority of its incoming energy is shunted towards the evaporation of water rather than direct heating of the surface. This is why in the hottest month in Manaus, Brazil, in the middle of the tropical rainforest and only three degrees from the equator, high temperatures average only 91 F (not appreciably different than humid Washington, DC’s 88 F). To appreciate the effect of water on surface heating of land areas, high temperatures in July in bone-dry Death Valley average 117 F.

Getting the surface temperature wrong will have additional consequences for vegetation and agriculture. In general, a wetter U.S. is one of bumper crops and good water supplies out west from winter snows, hardly the picture painted in the National Assessment.

If the government is going to spend time and our money on producing another assessment report, that report should be based on empirical evidence, not climate models. Note that USGCRP is a conglomeration of 13 federal agencies that had a 2016 budget of $2.6 billion for the climate assessment project. Did you get your money’s worth?

Climate modelers make some outlandish predictions, but occasionally there is a glimmer of honesty:

“The forcings that drive long-term climate change are not known with an accuracy sufficient to define future climate change.” — James Hansen, “Climate forcings in the Industrial era”, PNAS, Vol. 95, Issue 22, 12753-12758, October 27, 1998.

“In climate research and modeling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that the prediction of a specific future climate state is not possible.” — Final chapter, Draft TAR 2000 (Third Assessment Report), IPCC.

And remember: “The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary.” – H. L. Mencken

One other point:

Temperatures recorded by the US Climate Reference Network (USCRN) show no statistically significant trend since this network was established in 2004. This data is from state-of-the-art ultra-reliable triple redundant weather stations placed on pristine environments. As a result, these temperature data need none of the adjustments that plague the older surface temperature networks, such as USHCN and GHCN, which have been heavily adjusted to attempt corrections for a wide variety of biases. Using NOAA’s own USCRN data, which eliminates all of the squabbles over the accuracy of and the adjustment of temperature data, we can get a clear plot of pristine surface data.

 

BACKGROUND:

USGCRP Science?
What is now called the USGCRP has a murky, politicized past. It was established in 1989 and mandated by Congress in 1990 to “assist the Nation and the world to understand, assess, predict, and respond to human-induced and natural processes of global change.” It is to produce a National Climate Assessment every four year. Since 1990, it has produced four reports. The last full report, the 3rd National Climate Assessment, was in May 2014. Apparently, after the election of Mr. Trump, the USGCRP decided on the CSSR, released last week. As with prior NSGCRP reports, it ignores the “natural processes of global change”, which is part of its Congressional mandate.

Such political games are part of USGCRP’s established history. After the election of Mr. Bush, in 2000, under a prior name, the USGCRP released the 2000 U.S. National Assessment of Climate Change report. As shown in the 2008 report of the Nongovernmental International Panel for Climate Change (NIPCC) (Fig 16 & pp 14 to 16), the government report had projections / predictions that were nonsense. The government entity had two different climate models for climate change to 2090, which produced dramatically different results for perception, by regions. The worst example was for the Red River watershed in the Dakotas and Minnesota. One model had a precipitation drop of about 80%, turning the region into a desert, the second model had a precipitation increase of about 80%, resulting in dramatic flooding. The disparity between two models is but one example how inadequately tested global climate models may be used to project / predict almost anything. The federal courts found that the 2000 report did not meet the standards of the Data Quality Act, also called the Information Quality Act. The recent reports of the UN Intergovernmental Panel on Climate Change (IPCC) and the USGCRP have tried to cover up the disparities in the results of their global climate models by blending them into an ensemble. Usually, there are too few runs of any model to establish realistic forecasts for that model. The forecasts change with each run.

Further, the major problem remains, the models are not adequately tested to be used to form government policies on global warming / climate change. As comments by Patrick Michaels carried in last week’s TWTW illustrate, USGCRP ignores the existence of the important problem between the forecasts of atmospheric temperature trends by the global climate models with actual atmospheric temperature trends. The USGCRP ignores physical science.
