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:

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.”

Climate Madness 12, California is craziest

Climate on this planet has been changing all by itself for about four billion years. Now, either through ignorance or presumed political advantage, some politicians think they can stop climate change. That policy represents the real danger of global warming. Their magic formula is to stop carbon dioxide emissions from burning fossil fuels. Instead, they promote generation of electricity mainly from utility-scale solar or wind installations. As I have written before, solar and wind generation cannot respond to demand and are ultimately very unreliable and very expensive for ratepayers. Solar and wind would not exist without mandates and subsidies.

(See Vote NO on Arizona proposition 127 the renewable energy mandate and the references in that article.)

The United Nations Intergovernmental Panel on Climate Change (IPCC) has produced five major reports none of which contain any credible proof that carbon dioxide emissions are the principal cause of global warming. In the third report, the IPCC admits: “In climate research and modeling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that the long term prediction of future climate states is not possible.”

Following are some of the most recent manifestations of climate madness. We start with California climate craziness.

Climate Activists Want Gov. Brown To Shut Down Fossil Fuel Production In Calif.

By John Glennon

On the heels of Judge William Alsup’s decision to dismiss San Francisco’s and Oakland’s climate change lawsuits, local California officials are turning to new symbolic tactics, including pressuring Governor Jerry Brown ahead of his Global Climate Action Summit.

A group of 150 local elected officials sent an open letter to Governor Jerry Brown last week to chastise him for not completely shutting down fossil-fuel production in the state.

In the letter, the local officials demanded that Governor Brown pursue a meaty list of harmful and unrealistic policies:

“Recognizing that we are in a climate emergency, as you have rightly done, and given the grave public health and environmental justice consequences of fossil fuel production in California, we respectfully urge you to make a new statewide commitment and lay out a plan for California to achieve the following:

“End the issuance of permits for new fossil fuel projects, including permits for new oil and gas wells, infrastructure for fossil fuels, and petrochemical projects in California.

“Design a swift, managed decline of all fossil fuel production, starting with a 2,500-foot human health buffer zone around all occupied structures, public parks, and farms to protect public health and vulnerable communities.

“Commit the state to 100% clean, renewable energy, starting with significant investments in disadvantaged communities and areas that are already suffering the most from the negative impacts of fossil fuel extraction.” Read more Update: By a vote of 44 to 33, lawmakers in the California State Assembly passed SB 100, a bill that calls for the state to transition to emissions-free electricity production in less than three decades. Under the guidelines of the legislation, California must obtain 60 percent of its energy from renewable sources by 2030. The state’s electricity generation must be completely carbon free by 2045. The bill still needs to pass the CA senate. (Source)

 

Analysis: California’s Solar Panel Mandate Lowers CO2 Emissions by 0.32%

By Elizabeth Harrington

California will mandate solar panels on new homes out of concern for climate change, a policy that will raise prices in the most expensive home market in the country and does little to decrease the state’s carbon footprint. MIT reports: “California estimates that the new rule will cut emissions by 1.4 million metric tons over three years, which is a small fraction of the 440 million tons the state generated in 2015.” Emissions would be reduced by 0.32 percent. Read more

 

Utility blaming climate change, not its fallen power lines, for California wildfires

By Thomas Lifson

My cable news viewing is frequently interrupted by commercials instructing Northern Californians that climate change is responsible for the state’s current ordeal with multiple large wildfires. This is a contemptible attempt by utilities to evade responsibility for the damages caused by their power lines located near combustible forests (made much more combustible by policies preventing harvesting “old growth” and clearing deadwood). Read more

 

California and the L. A. Times latest climate alarmist absurdities

by Larry Hamlin

The Times article fails to note the UN IPCC conclusions regarding the undisputed inadequacy of “climate models” which it described in its AR3 climate report as “In climate research and modeling, we should recognize that we are dealing with a coupled non-linear chaotic system, and therefore that the long term prediction of future climate states is not possible.”

The Times article provides speculative alarmist “model driven” assertions about future coastal sea level rise contained in the state’s report which it characterizes as “Until recently, scientists and state policymakers worked with a projection that sea level rise by the end of this century could amount to about 5.48 feet in California under the worst case scenario. But the latest reports and state policies are now accounting for the extreme possibility that sea level rise could exceed 9 feet.”

Of course as is always the case with these wild and absurd sea level rise claims actual California coastal sea level rise measured NOAA tide gauge data with records going back more than 100 years is completely ignored by the state and L. A. Times because it shows absolutely no coastal sea level rise acceleration occurring at the states coastal locations with sea level rise occurring at steady rates between about 3 to 8 inches per CENTURY. Read more

REPORT: How The Billion-Dollar-A-Year Climate Industry Weaponized State Attorneys General

by Michael Bastasch, Daily Caller

A new report based on documents collected over two-and-a-half years through open records requests outlines an “elaborate campaign” by the “billion-dollar per year climate industry” to weaponize state attorneys general (AGs) in service of the global warming agenda.

That campaign culminated in what the report labels “law enforcement for hire” because it allows political donors to pay for state prosecutors “in the service of an ideological, left-wing, climate policy agenda.”

“It represents private interests commandeering the state’s police powers to target opponents of their policy agenda and to hijack the justice system as a way to overturn the democratic process’s rejection of a political agenda,” Competitive Enterprise senior fellow Chris Horner wrote in his report, a copy of which was given to The Daily Caller News Foundation. Read more

Smart meters: Data spy or key energy device

The United States Court of Appeals for the Seventh Circuit has handed down a landmark ruling, stating that data collected by smart meters is protected by the Fourth Amendment.

The court pointed out that the smart devices, in fact, collect information for a deeper insight which can be obtained by thermal imaging tech. Furthermore, the court held that residents have a reasonable expectation of privacy and government access of this data constitutes, in essence, a search.

Jamie Williams, staff attorney at the Electronic Frontier Foundation, said: “The Seventh Circuit recognized that smart meters pose serious risks to the privacy of all of our homes, and that rotely applying analog-era case law to the digital age simply doesn’t work.”

This has shone the spotlight on whether or not smart meters can be used to spy on consumers. Through the collection of usage data at high frequencies (every five, 15 or 30 minutes), a clear picture can be garnered of activity occurring on the property.

Individual lifestyles can be examined, such as predicting daily routine, sleep patterns, meal times and periods away from the property. Read more

Climate Craziness, Politics, and Hypocrisy

Forest thinning needed to save water

Dense forests suck up surface and groundwater and dump it into the atmosphere through the process of evapotranspiration. This means that there is less water for other uses.

“There are too many trees in Sierra Nevada forests, say scientists affiliated with the National Science Foundation (NSF) Southern Sierra Critical Zone Observatory (CZO).”

A new study supported by the National Science Foundation published in the journal Ecohydrology (see press release) proclaims “Billions of gallons of water saved by thinning forests.” The study of the Sierra Nevada Mountains in California notes that “excessive evapotranspiration may harm a fragile California water system, especially during prolonged, warm droughts.”

The primary methods of good forest thinning are fire and logging.

Forest Service policy exacerbated sound forest management. Remember Smokey the Bear, “only you can prevent forest fires?” But fire is nature’s way of managing forests. Logging was largely reduced for misguided environmental reasons such as saving the spotted owl.

From the NSF study:

“Forest wildfires are often considered disasters,” said Richard Yuretich, director of NSF’s CZO program, which funded the research. “But fire is part of healthy forest ecosystems. By thinning out trees, fires can reduce water stress in forests and ease water shortages during droughts. And by reducing the water used by plants, more rainfall flows into rivers and accumulates in groundwater.”

Using data from CZO measurement towers and U.S. Geological Survey satellites, researchers found that over the period 1990 to 2008, fire-thinned forests saved 3.7 billion gallons of water annually in California’s Kings River Basin and …17 billion gallons of water annually in the American River Basin — water that would otherwise have been lost through evapotranspiration.

Forest thinning has increased in recent decades in an effort to stave off disastrous wildfires fueled by dense forests. This study shows that restoring forests through mechanical thinning or wildfire can also save California billions of gallons of water each year.

Perhaps we should take guidance from the first land managers in North America, the Indians. In my article “The Pristine Myth” I note the following:

Archaeological and anthropological research during the last 25 years or so, shows that much of what we thought was pristine in the Western Hemisphere, even the Amazon rain forest, is actually human-formed landscape created by the first New World inhabitants, the Indians. It seems that American Indians, from North America, Mexico and South America, were the ultimate land managers, and they transformed the land to suit their needs. They constructed the world’s largest gardens.

American Indians built cities and civilizations, cultivated forests and farms, and developed more than half of the crops grown worldwide today. Indians, rather than subsist passively on what wild nature provided, instead survived by cleverly exploiting their environment. Their principal tool was fire. They did not domesticate animals for meat, but instead used fire to change whole ecosystems to raise deer, elk, and bison.

Forest thinning may increase runoff and supplement our water supply

A new study (“Effects of Climate Variability and Accelerated Forest Thinning on Watershed-Scale Runoff in Southwestern USA Ponderosa Pine Forests” published October 22, 2014) conducted by The Nature Conservancy and Northern Arizona University recommends accelerated forest thinning by mechanical means and controlled burns in central and northern Arizona forests. The study estimates that such thinning will increase runoff by about 20 percent, add to our water supply, and make forests more resilient.

Renewable energy mandates and politics versus science

Competing renewable energy mandate legislation will appear on the Arizona this fall. You can read about them in two Arizona Daily Star stories:

Arizona utility APS crafts renewable-energy initiative with escape clause

Arizona Senate puts utility-written renewable energy plan on ballot

Neither addresses the real issue: electricity produced from utility-scale solar and wind is unreliable, expensive, plays havoc with electrical grid stability, and is not as green as advertized. Rather than play with tricky fixes, the Arizona legislature should repeal the Arizona Corporation Commission’s renewable energy mandate and forbid the ACC from mandating how electricity is generated. I can find no place in the Arizona Constitution nor in the Arizona Revised Statutes that gives the ACC authority to impose such mandates.

For background of ACC action, read a report from the Goldwater Institute: “Rediscovering the ACC’s Roots: Returning to the Original Purpose of the Arizona Corporation Commission” (link)

Here is the executive summary of the 26-page report:

The Arizona Corporation Commission was established through the state constitution to regulate corporations, public utilities, securities, and other investments. But in an unprecedented move, the Arizona Corporation Commission sought to single-handedly determine alternative energy policy in Arizona with a bold and unconstitutional energy mandate in 2006.1 This mandate forced energy producers to embrace state-favored alternatives instead of deciding for themselves which options are most attractive in Arizona.

Arizonans now face the real threat that the Arizona Corporation Commission will continue to seize power meant to be held by the state’s legislative branch. Important decisions about energy policy, corporate governance, and other areas have been removed from the legislative process which, for all its faults, offers more transparency, citizen input, and accountability than the opaque and bureaucratic proceedings of the Arizona Corporation Commission.

The framers of the Arizona Constitution had serious concerns about the Commission’s potential to abuse its authority. Records of the state constitutional debate show the constitution’s authors intentionally limited the Commission’s powers to prevent interference with internal business decisions. The framers’ fears have been borne out.

The Commission’s attempt to act as the state’s de facto energy czar clearly oversteps its original role.

Arizona courts should re-establish a proper balance between the Commission and legislative power. Courts in other states with similar utility regulatory commissions already have concluded such agencies don’t have constitutional authority to mandate statewide policy. The Legislature also can reassert its authority by ordering an audit of the Commission that would recommend ways to streamline the agency and to restore it to its proper role. Finally, the state constitution could be amended to transfer necessary functions to other agencies and decommission the ACC to stop its policymaking power grabs, which Arizona’s founders specifically aimed to prevent.

See these articles for more detail on the consequences of the ACC mandate:

Six reasons Arizona should repeal its renewable energy standards mandate

The economic impact of Arizona’s renewable energy mandate

The high cost of electricity from wind and solar generation

The more installed solar and wind capacity per capita a country has, the higher the price people pay for electricity.

Political correctness versus science:

The alleged rationale for these mandates is that we must reduce carbon dioxide emissions to forestall dread global warming. But, there is no physical evidence that emissions from fossil fuels play a significant role in driving global temperature. See these ADI posts for more detail:

A Simple Question for Climate Alarmists

“What physical evidence supports the contention that carbon dioxide emissions from burning fossil fuels are the principal cause of global warming since 1970?” I 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, none could cite any supporting physical evidence.

Evidence that CO2 emissions do not intensify the greenhouse effect

The “greenhouse” hypothesis of global warming makes four major predictions of what we should see if the “greenhouse effect” is intensified by adding carbon dioxide to the atmosphere. All four predictions are shown by physical evidence to be wrong.

Failure of climate models shows that carbon dioxide does not drive global temperature

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

Illustrating the failure of the climate movement – in one graph

This post is reblogged from

People like Bill McKibben of 350.org make a big deal out of the “successes” of carbon divestment, where the 350.org organization bullies convinces some hapless organization to divest from coal and petroleum stocks in investment portfolios. Besides the fact that this has no real impact, since when one person or group “divests”, another one buys the shares up, this graph shows why 350.org, Sierra Club, Greenpeace, NRDC, and the whole lot of climate campaigners are just practicing an exercise in futility.

Dr. Roger Pielke writes on Twitter:

I’m preparing some slides for an upcoming talk (on climate policy, yowza!). The attached is an effort to show in a readily understandable way the mind-bending scale of the energy challenge associated with deep decarbonization. What do you think?

This graph of global fossil fuel consumption tells the true story: green efforts to reduce fossil fuel use have not succeed with any impact at all. With a 57% increase in fossil fuel use since 1992, their efforts have been completely without effect.

Winter Weather forecast – NOAA vs Old Farmer’s Almanac

The U.S. National Oceanic and Atmospheric Administration (NOAA) has just issued its prediction for temperature and precipitation for the winter of 2017-2018. You can see NOAA maps and a video here.

In general, NOAA predicts a colder and wetter winter in the northwest, and a warmer and drier winter in the southwest. Here are the NOAA maps:

The Old Farmer’s Almanac predicts the opposite. Go to https://www.almanac.com/weather/longrange and click on a region on the map for detailed predictions.

 

For the southwest (region 14). OFA predicts:

Winter will be colder than normal, with above-normal precipitation. The coldest periods will be from late November into early December and in late December and mid-January. Snowfall will be above normal in the east and near to below normal in the west, with the snowiest periods in late December, early and mid-January, and early February. April and May will be slightly rainier than normal, with temperatures below normal in the east and near normal in the west. Summer will be slightly hotter than normal, with the hottest periods in mid- and late June and early August. Rainfall will be below normal in the northwest and above normal in the southeast. September and October will be cooler and drier than normal.

 

For the deep south (region 8) OFA predicts “Winter will be rainier and slightly cooler than normal, with near- or above-normal snowfall.” NOAA is predicting warmer and dryer.

 

NOAA predictions are based on observation and computer modeling (sometimes with false assumptions as to what drives climate). The Old Farmer’s Almanac forms its predictions by comparing solar patterns and historical weather conditions with current solar activity. (Read more)

Print out this post and check back at the end of February to see which organization came closer to reality. Much depends upon whether or not we see a La Niña develop this winter.

Trump, the National Climate Assessment report, and fake news

The New York Times recently obtained a draft of the up-coming National Climate Assessment report. NYT is worried that the Trump administration will suppress the report. However, according to scientists who worked on the report, it has been available online since last January. (See Daily Caller story) You can download the 545-page 3rd draft report here, but don’t bother.

Besides the “fake news” story in the New York Times, we have a “fake news” story from the Associated Press printed by the Arizona Daily Star. Within that story is this sentence: Contradicting Trump’s claims that climate change is a “hoax,” the draft report representing the consensus of 13 federal agencies concludes that the evidence global warming is being driven by human activities is “unambiguous.”

Definition of unambiguous: “Admitting of no doubt or misunderstanding; having only one meaning or interpretation and leading to only one conclusion.”

Because of that statement and this one: “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, I downloaded the report to see just how unambiguous the evidence is. Here is what I found.

1) All their evidence consists of computer modeling. There is no physical evidence. That’s just like the previous National Climate Assessment report. They are, in essence, claiming that evidence of warming is evidence of the cause of warming.

2) On page 139, they discuss how they attribute causes:

Detection and attribution of climate change involves assessing the causes of observed changes in the climate system through systematic comparison of climate models and observations using various statistical methods. An attributable change refers to a change in which the relative contribution of causal factors has been evaluated along with an assignment of statistical confidence.

3) Beginning on page 144, they discuss “major uncertainties.” Oops, not so “unambiguous.”

The transient climate response (TCR) is defined as the global mean surface temperature change at the time of CO2 doubling in a 1%/year CO2 transient increase experiment. The TCR of the climate system to greenhouse gas increases remains uncertain, with ranges of 0.9° to 2.0°C (1.6° to 3.6°F) and 0.9° to 2.5°C (1.6° to 4.5°F) in two recent assessments. The climate system response to aerosol forcing (direct and indirect effects combined) remains highly uncertain, because although more of the relevant processes are being in included in models, confidence in these representations remains low. Therefore, there is considerable uncertainty in quantifying the attributable warming contributions of greenhouse gases and aerosols separately. There is uncertainty in the possible levels of internal climate variability, but current estimates likely  range of +/- 0.1°C, or 0.2°F, over 60 years) would have to be too low by more than a factor or two or three for the observed trend to be explainable by internal variability.

Does that sound like the evidence is unambiguous?

“There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.” – Mark Twain, Life on the Mississippi

UPDATE: The material above refers to the third draft of the report. The fifth draft has just become available. One analyst noticed “that the latest draft climate report, published in June, had seemingly left out a rather embarrassing table from the Executive Summary, one that had previously been written into the Third Draft, published last December.” What has been omitted is the fact “that the hottest temperatures, (averaged over the US), were not only much, much higher in the 1930s. They were also higher during the 1920s. Indeed there have been many other years with higher temperatures than most of the recent ones.” (Source)

I would not call it a hoax as does President Trump; I’d call it a scam. The National Climate Assessment itself is fake news; a political, rather than a scientific document.

“It is difficult to get a man to understand something, when his salary depends on his not understanding it.” – Upton Sinclair.

Additional reading:

Alan Carlin, a former senior EPA analyst, says computer models fail because: The bottom-up GCM was a bad approach from the start and should never have been paid for by the taxpayers. All that we have are computer models that were designed and then tuned to lead to the IPCC’s desired answers and have had a difficult time even doing that.

So not only are the results claiming that global temperatures are largely determined by atmospheric CO2 wrong, but the basic methodology is useless. Climate is a coupled, non-linear chaotic system, and the IPCC agrees that this is the case. It cannot be usefully modeled by using necessarily limited models which assume the opposite. Read more

Dr. Tim Ball: Uncovered: decades-old government report showing climate data was bad, unfit for purpose. In 1999, the National Academy of Sciences, the research arm of the National Research Council, released a study expressing concern about the accuracy of the data used in the debate over climate change. They said there are,

“Deficiencies in the accuracy, quality and continuity of the records,” that “place serious limitations on the confidence that can be placed in the research results.”

Pima County Az tilting at climate change

In the novel “The Ingenious Nobleman Mister Quixote of La Mancha” by Miguel de Cervantes, first published in 1605, the protagonist, Don Quixote, imagines that windmills are giants to be destroyed. Don Quixote attacks the windmills with his lance, an action called “tilting,” all to no avail. From this story comes the idiom “tilting at windmills” which means confrontations where adversaries are incorrectly perceived, or courses of action are based on misinterpreted or misapplied heroic, romantic, or idealistic justifications. We can add the motivation of political correctness to the Pima County, Arizona, plan to reduce carbon dioxide emissions.

Since President Trump has withdrawn the U.S. from the Paris Climate Accord, Pima County Supervisors have approved their own version of the Paris Accord and pledge to reduce the County’s carbon dioxide emissions.

In a previous article, “Impact of Paris climate accord and why Trump was right to dump it” I show that if all countries fully comply with their promises under the Paris Accord, it would make a difference of only 0.17°C by the year 2100.

According to an article in the Arizona Daily Star, Pima County government will attempt to cut its greenhouse-gas emissions by 42 percent from current levels by 2025, mainly by using more solar energy. The county government will attempt to get 40 percent of its electricity from very unreliable solar generation. The county will also buy 20 new electric-powered sedans for its vehicle fleet a year, at $30,000 to $40,000 apiece.

These electric vehicles are much more expensive than gasolene-powered versions of the same model. According to a new paper published in the journal Issues in Science and Technology entitled Electric Vehicles: Climate Saviors, Or Not?, driving an electric vehicle rather than a conventional petroleum-powered vehicle effectively does nothing to reduce global-scale CO2 emissions. The net carbon dioxide emissions depend greatly on how the electricity for recharge is generated.

The Star story also notes that the county government’s share of regional greenhouse gas emissions is minuscule. It generated less than 0.1 percent of all emissions produced in eastern Pima County in 2014.

In my opinion, Pima County’s action with regard to reducing carbon dioxide emissions is simply a quixotic exercise in political correctness that will have absolutely no effect on global temperature nor on Tucson temperature. The action also diverts taxpayer money from projects that would actually benefit county citizens, such as repairing roads.

“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, Third Assessment Report, IPCC.

US Summers Are Getting Much Cooler

Reblogged from Tony Hellers RealClimate Science:

Every single metric shows that summer maximum temperatures are cooling in the US, and that heatwaves are becoming shorter, less intense and covering a smaller area.

Climate scientists say the exact opposite of the data, because they are consultants being paid to push the global warming scam.
