From the Register's Opinion Page: What to say to a global warming advocate

ClimateGate – This scandal began the latest round of revelations when thousands of leaked documents from Britain's East Anglia Climate Research Unit showed systematic suppression and discrediting of climate skeptics' views and discarding of temperature data, suggesting a bias for making the case for warming. Why do such a thing if, as global warming defenders contend, the "science is settled?"

FOIGate – The British government has since determined someone at East Anglia committed a crime by refusing to release global warming documents sought in 95 Freedom of Information Act requests. The CRU is one of three international agencies compiling global temperature data. If their stuff's so solid, why the secrecy?

ChinaGate – An investigation by the U.K.'s left-leaning Guardian newspaper found evidence that Chinese weather station measurements not only were seriously flawed, but couldn't be located. "Where exactly are 42 weather monitoring stations in remote parts of rural China?" the paper asked. The paper's investigation also couldn't find corroboration of what Chinese scientists turned over to American scientists, leaving unanswered, "how much of the warming seen in recent decades is due to the local effects of spreading cities, rather than global warming?" The Guardian contends that researchers covered up the missing data for years.

HimalayaGate – An Indian climate official admitted in January that, as lead author of the IPCC's Asian report, he intentionally exaggerated when claiming Himalayan glaciers would melt away by 2035 in order to prod governments into action. This fraudulent claim was not based on scientific research or peer-reviewed. Instead it was originally advanced by a researcher, since hired by a global warming research organization, who later admitted it was "speculation" lifted from a popular magazine. This political, not scientific, motivation at least got some researcher funded.

PachauriGate – Rajendra Pachauri, the IPCC chairman who accepted with Al Gore the Nobel Prize for scaring people witless, at first defended the Himalaya melting scenario. Critics, he said, practiced "voodoo science." After the melting-scam perpetrator 'fessed up, Pachauri admitted to making a mistake. But, he insisted, we still should trust him.

PachauriGate II – Pachauri also claimed he didn't know before the 192-nation climate summit meeting in Copenhagen in December that the bogus Himalayan glacier claim was sheer speculation. But the London Times reported that a prominent science journalist said he had pointed out those errors in several e-mails and discussions to Pachauri, who "decided to overlook it." Stonewalling? Cover up? Pachauri says he was "preoccupied." Well, no sense spoiling the Copenhagen party, where countries like Pachauri's India hoped to wrench billions from countries like the United States to combat global warming's melting glaciers. Now there are calls for Pachauri's resignation.

SternGate – One excuse for imposing worldwide climate crackdown has been the U.K.'s 2006 Stern Report, an economic doomsday prediction commissioned by the government. Now the U.K. Telegraph reports that quietly after publication "some of these predictions had been watered down because the scientific evidence on which they were based could not be verified." Among original claims now deleted were that northwest Australia has had stronger typhoons in recent decades, and that southern Australia lost rainfall because of rising ocean temperatures. Exaggerated claims get headlines. Later, news reporters disclose the truth. Why is that?

SternGate II – A researcher now claims the Stern Report misquoted his work to suggest a firm link between global warming and more-frequent and severe floods and hurricanes. Robert Muir-Wood said his original research showed no such link. He accused Stern of "going far beyond what was an acceptable extrapolation of the evidence." We're shocked.

AmazonGate – The London Times exposed another shocker: the IPCC claim that global warming will wipe out rain forests was fraudulent, yet advanced as "peer-reveiwed" science. The Times said the assertion actually "was based on an unsubstantiated claim by green campaigners who had little scientific expertise," "authored by two green activists" and lifted from a report from the World Wildlife Fund, an environmental pressure group. The "research" was based on a popular science magazine report that didn't bother to assess rainfall. Instead, it looked at the impact of logging and burning. The original report suggested "up to 40 percent" of Brazilian rain forest was extremely sensitive to small reductions in the amount of rainfall, but the IPCC expanded that to cover the entire Amazon, the Times reported.

PeerReviewGate – The U.K. Sunday Telegraph has documented at least 16 nonpeer-reviewed reports (so far) from the advocacy group World Wildlife Fund that were used in the IPCC's climate change bible, which calls for capping manmade greenhouse gases.

RussiaGate – Even when global warming alarmists base claims on scientific measurements, they've often had their finger on the scale. Russian think tank investigators evaluated thousands of documents and e-mails leaked from the East Anglia research center and concluded readings from the coldest regions of their nation had been omitted, driving average temperatures up about half a degree.

Russia-Gate II – Speaking of Russia, a presentation last October to the Geological Society of America showed how tree-ring data from Russia indicated cooling after 1961, but was deceptively truncated and only artfully discussed in IPCC publications. Well, at least the tree-ring data made it into the IPCC report, albeit disguised and misrepresented.

U.S.Gate – If Brits can't be trusted, are Yanks more reliable? The U.S. National Climate Data Center has been manipulating weather data too, say computer expert E. Michael Smith and meteorologist Joesph D'Aleo. Forty years ago there were 6,000 surface-temperature measuring stations, but only 1,500 by 1990, which coincides with what global warming alarmists say was a record temperature increase. Most of the deleted stations were in colder regions, just as in the Russian case, resulting in misleading higher average temperatures.

IceGate – Hardly a continent has escaped global warming skewing. The IPCC based its findings of reductions in mountain ice in the Andes, Alps and in Africa on a feature story of climbers' anecdotes in a popular mountaineering magazine, and a dissertation by a Switzerland university student, quoting mountain guides. Peer-reviewed? Hype? Worse?

ResearchGate – The global warming camp is reeling so much lately it must have seemed like a major victory when a Penn State University inquiry into climate scientist Michael Mann found no misconduct regarding three accusations of climate research impropriety. But the university did find "further investigation is warranted" to determine whether Mann engaged in actions that "seriously deviated from accepted practices for proposing, conducting or reporting research or other scholarly activities." Being investigated for only one fraud is a global warming victory these days.

ReefGate – Let's not forget the alleged link between climate change and coral reef degradation. The IPCC cited not peer-reviewed literature, but advocacy articles by Greenpeace, the publicity-hungry advocacy group, as its sole source for this claim.

AfricaGate – The IPCC claim that rising temperatures could cut in half agricultural yields in African countries turns out to have come from a 2003 paper published by a Canadian environmental think tank – not a peer-reviewed scientific journal.

DutchGate – The IPCC also claimed rising sea levels endanger the 55 percent of the Netherlands it says is below sea level. The portion of the Netherlands below sea level actually is 20 percent. The Dutch environment minister said she will no longer tolerate climate researchers' errors.

AlaskaGate – Geologists for Space Studies in Geophysics and Oceanography and their U.S. and Canadian colleagues say previous studies largely overestimated by 40 percent Alaskan glacier loss for 40 years. This flawed data are fed into those computers to predict future warming.

Fold this column up and lay it next to your napkin the next time you have Al Gore or his ilk to dine. It should make interesting after-dinner conversation.

Whoops forgot this one...... <a href=http://joannenova.com.au/2010/02/scandinavia-gate/>Scandinavia-gate</a>

[CdnRepublican]

From the CRU code file osborn-tree6/briffa_sep98_d.pro , used to prepare a graph purported to be of Northern Hemisphere temperatures and reconstructions.

;
; Apply a VERY ARTIFICAL correction for decline!!
;
yrloc=[1400,findgen(19)*5.+1904]
valadj=[0.,0.,0.,0.,0.,-0.1,-0.25,-0.3,0.,- 0.1,0.3,0.8,1.2,1.7,2.5,2.6,2.6,$
2.6,2.6,2.6]*0.75 ; fudge factor
if n_elements(yrloc) ne n_elements(valadj) then message,’Oooops!’
;
yearlyadj=interpol(valadj,yrloc,timey)

This, people, is blatant data-cooking, with no pretense otherwise. It flattens a period of warm temperatures in the 1940s 1930s — see those negative coefficients? Then, later on, it applies a positive multiplier so you get a nice dramatic hockey stick at the end of the century.

All you apologists weakly protesting that this is research business as usual and there are plausible explanations for everything in the emails? Sackcloth and ashes time for you. This isn’t just a smoking gun, it’s a siege cannon with the barrel still hot.

UPDATE2: Now the data is 0.75 scaled. I think I interpreted the yrloc entry incorrectly last time, introducing an off-by-one. The 1400 point (same as the 1904) is omitted as it confuses gnuplot. These are details; the basic hockey-stick shape is unaltered.

UPDATE3: Graphic is tenmporily unavailable due to a server glitch. I’m contacting the site admins about this.

Any programmer looking at their 'models' would just laugh.

I wrote a program for a client once - it was completely random and bs but seem to give him what he wanted. Ie we cooked the data - much like the girls at CRU did to satisfy their political masters.

[CdnRepublican]

This is not, sadly, all that unusual. Simply put, scientists aren’t software engineers. They don’t keep their code in nice packages and they tend to use whatever language they’re comfortable with. Even if they were taught to keep good research notes in the past, it’s not unusual for things to get sloppy later. But put this in the context of what else we know from the CRU data dump:

1. They didn’t want to release their data or code, and they particularly weren’t interested in releasing any intermediate steps that would help someone else

2. They clearly have some history of massaging the data — hell, practically water-boarding the data — to get it to fit their other results. Results they can no longer even replicate on their own systems.

3. They had successfully managed to restrict peer review to what we might call the “RealClimate clique” — the small group of true believers they knew could be trusted to say the right things.

Climategate: The Big Picture

As new fraud is revealed almost daily, the full story of how the AGW scam came to pass is taking shape.
February 19, 2010 - by Charlie Martin


It’s been less than three months since the Climategate files were first revealed to the world, and an amazing lot has happened — so much that I think it’s worth bringing things together in one place.

This is an extension of the “fast facts” post I wrote a couple months ago. The facts and threads are now coming together into a narrative, a big picture combining what we learned from the letters and what we have learned since. <a href=http://pajamasmedia.com/blog/climategate-the-big-picture/>full story</a>

Climategate 2010: The Inconvenient Facts About Global Warming

Scientists, economists, and other experts present the case against manmade global warming fears at the Heartland Institute’s Fourth International Conference on Climate Change. (DON'T MISS PJTV: LIVE COVERAGE AND INTERVIEWS FROM THE CHICAGO CLIMATE CONFERENCE.)
In the wake of the Climategate scandal, panelists and audience members at the Fourth International Conference on Climate Change (ICCC4) indicated growing confidence that the tide is turning in favor of those who believe that manmade global warming is not a crisis.

More than 700 people — including a good many scientists, along with economists, policy analysts, and legislators — have gathered together since Sunday night, discussing the once-settled but increasingly controversial proposition of an anthroprogenic global warming (AGW) crisis. Any triumphalism was averted by a general agreement to explore real-world facts and test the assertions of alarmists. The presenters and audience members continually asked whether the data says what the modelers say it does. <a href=http://pajamasmedia.com/blog/climategate-2010-the-inconvenient-facts-about-global-warming/>continued</a>

Amazongate: the smoking gun
More than five months after the IPCC was accused of making assertions on the fate of the Amazon forest on the basis of a non-peer reviewed WWF report, it now appears that the original source of the IPPC's claim is a Brazilian educational website which was taken down in 2003 (pictured - click to enlarge).

Furthermore, it appears that this is the only source of the IPCC's claim that made up the basis of "Amazongate" – that the IPCC was, once again, using unsubstantiated material which exaggerated the threat. This website, therefore, is the "smoking gun", the latest evidence to suggest that the IPCC is breaking its own rules. <a href=http://eureferendum.blogspot.com/2010/07/amazongate-smoking-gun.html>continued</a>

Killing the green wave

Most people understand what an independent public inquiry is

By LORRIE GOLDSTEIN, QMI Agency

Last Updated: July 13, 2010
Most people understand what an independent public inquiry is.

Except climate scientists and politicians.

In a public inquiry, a third party with no interest in the outcome — typically a judge — is appointed by government with a mandate to investigate an issue of public concern.

The inquiry has its own legal counsel, investigators and budget.

It has the power to compel witnesses to testify publicly, to cross-examine them, to demand documents and call in outside experts.

By that standard, the three official “inquiries” into “Climategate” — the last of which recently “exonerated” scientists at the Climatic Research Unit (CRU) of the University of East Anglia (UEA) — again were farces.

Two were cases of the UEA appointing sympathetic academics to investigate itself.

The third was a one-day hearing before a British parliamentary committee in a country that has been at the forefront of global warming hysteria.

Climategate involved the unsanctioned release of thousands of e-mails and documents by leading climate scientists.

The most infamous came from former CRU director Phil Jones about using a “trick” to “hide the decline” in temperatures, plus discussing with colleagues ways to hide data from freedom of information requests under U.K. law.

The latest “inquiry” found what the two previous ones did — the science of climate change is sound (surprise!), but researchers were unprofessionally secretive.

While warmists declared “victory” with each predictable report, and are still fighting skeptics over the credibility of various claims in the 2007 report of the UN’s Intergovernmental Panel on Climate Change, which basically described global warming as an existential threat, much of the public has stopped listening.

International polls show concern over climate change dropping — even in countries such as Germany, which has heavily invested in renewable energy — and most significantly in the U.S., the world’s No. 2 greenhouse gas emitter.

With China, the world’s largest emitter, refusing to accept hard emission targets, global negotiations to draft a successor agreement to the (widely ignored) Kyoto accord, which expires in 2012, are stalled.

There’ll be another attempt in Cancun this November after talks all but fell apart in Copenhagen last December, but the effort is losing steam.

One reason is the realization global, centrally-imposed diktats to cut emissions over mandated time frames — mindful of the former Soviet Union’s absurd five-year plans for the production of tin — don’t work.

Another is politicians now have to move from promising to lower emissions, which is easy, to lowering them, which, as the public is discovering, is ruinously expensive, doesn’t work and will lead to power shortages.

Optimists might say, as Newsweek did Monday in an essay, “A Green Retreat: Why the environment is no longer a surefire political winner,” that climate change is finally being put into perspective as one of many challenges we face, not necessarily the most significant.

Unfortunately, the global political fight never has been about the environment, but about expanding government power domestically and creating, internationally, a socialist, money-sucking scheme to transfer wealth from the first world to the third. That effort is proceeding.

It’s how Stephen Harper accurately described Kyoto, before he became prime minister and stopped talking about the issue honestly.

As for the opposition parties, they’re so uninformed about the devastating economic consequences of what they’re advocating, it’s just scary.

My Global Warming Skepticism, for Dummies
July 17th, 2010 by Roy W. Spencer, Ph. D.
http://www.drroyspencer.com/2010/07/my- ... r-dummies/

I receive many e-mails, and a recurring complaint is that many of my posts are too technical to understand. This morning’s installment arrived with the subject line, “Please Talk to Us”, and suggested I provide short, concise, easily understood summaries and explanations “for dummies”.

So, here’s a list of basic climate change questions, and brief answers based upon what I know today. I might update them as I receive suggestions and comments. I will also be adding links to other sources, and some visual aids, as appropriate.

Deja vu tells me I might have done this once before, but I’m too lazy to go back and see. So, I’ll start over from scratch. (Insert smiley)

It is important to understand at the outset that those of us who are skeptical of mankind’s influence on climate have a wide variety of views on the subject, and we can’t all be right. In fact, in this business, it is really easy to be wrong. It seems like everyone has a theory of what causes climate change. But it only takes one of us to be right for the IPCC’s anthropogenic global warming (AGW) house of cards to collapse.

As I like to say, taking measurements of the climate system is much easier than figuring out what those measurements mean in terms of cause and effect. Generally speaking, it’s not the warming that is in dispute…it’s the cause of the warming.

If you disagree with my views on something, please don’t flame me. Chances are, I’ve already heard your point of view; very seldom am I provided with new evidence I haven’t already taken into account.

1) Are Global Temperatures Rising Now? There is no way to know, because natural year-to-year variability in global temperature is so large, with warming and cooling occurring all the time. What we can say is that surface and lower atmospheric temperature have risen in the last 30 to 50 years, with most of that warming in the Northern Hemisphere. Also, the magnitude of recent warming is somewhat uncertain, due to problems in making long-term temperature measurements with thermometers without those measurements being corrupted by a variety of non-climate effects. But there is no way to know if temperatures are continuing to rise now…we only see warming (or cooling) in the rearview mirror, when we look back in time.

2) Why Do Some Scientists Say It’s Cooling, while Others Say that Warming is Even Accelerating? Since there is so much year-to-year (and even decade-to-decade) variability in global average temperatures, whether it has warmed or cooled depends upon how far back you look in time. For instance, over the last 100 years, there was an overall warming which was stronger toward the end of the 20th Century. This is why some say “warming is accelerating”. But if we look at a shorter, more recent period of time, say since the record warm year of 1998, one could say that it has cooled in the last 10-12 years. But, as I mentioned above, neither of these can tell us anything about whether warming is happening “now”, or will happen in the future.

3) Haven’t Global Temperatures Risen Before? Yes. In the longer term, say hundreds to thousands of years, there is considerable indirect, proxy evidence (not from thermometers) of both warming and cooling. Since humankind can’t be responsible for these early events, this is evidence that nature can cause warming and cooling. If that is the case, it then opens up the possibility that some (or most) of the warming in the last 50 years has been natural, too. While many geologists like to point to much larger temperature changes are believed to have occurred over millions of years, I am unconvinced that this tells us anything of use for understanding how humans might influence climate on time scales of 10 to 100 years.

4) But Didn’t the “Hockey Stick” Show Recent Warming to be Unprecedented? The “hockey Stick” reconstructions of temperature variations over the last 1 to 2 thousand years have been a huge source of controversy. The hockey stick was previously used by the IPCC as a veritable poster child for anthropogenic warming, since it seemed to indicate there have been no substantial temperature changes over the last 1,000 to 2,000 years until humans got involved in the 20th Century. The various versions of the hockey stick were based upon limited amounts of temperature proxy evidence — primarily tree rings — and involved questionable statistical methods. In contrast, I think the bulk of the proxy evidence supports the view that it was at least as warm during the Medieval Warm Period, around 1000 AD. The very fact that recent tree ring data erroneously suggests cooling in the last 50 years, when in fact there has been warming, should be a warning flag about using tree ring data for figuring out how warm it was 1,000 years ago. But without actual thermometer data, we will never know for sure.

5) Isn’t the Melting of Arctic Sea Ice Evidence of Warming? Warming, yes…manmade warming, no. Arctic sea ice naturally melts back every summer, but that meltback was observed to reach a peak in 2007. But we have relatively accurate, satellite-based measurements of Arctic (and Antarctic) sea ice only since 1979. It is entirely possible that late summer Arctic Sea ice cover was just as low in the 1920s or 1930s, a period when Arctic thermometer data suggests it was just as warm. Unfortunately, there is no way to know, because we did not have satellites back then. Interestingly, Antarctic sea ice has been growing nearly as fast as Arctic ice has been melting over the last 30+ years.

6) What about rising sea levels? I must confess, I don’t pay much attention to the sea level issue. I will say that, to the extent that warming occurs, sea levels can be expected to also rise to some extent. The rise is partly due to thermal expansion of the water, and partly due to melting or shedding of land-locked ice (the Greenland and Antarctic ice sheets, and glaciers). But this says nothing about whether or not humans are the cause of that warming. Since there is evidence that glacier retreat and sea level rise started well before humans can be blamed, causation is — once again — a major source of uncertainty.

7) Is Increasing CO2 Even Capable of Causing Warming? There are some very intelligent people out there who claim that adding more carbon dioxide to the atmosphere can’t cause warming anyway. They claim things like, “the atmospheric CO2 absorption bands are already saturated”, or something else very technical. [And for those more technically-minded persons, yes, I agree that the effective radiating temperature of the Earth in the infrared is determined by how much sunlight is absorbed by the Earth. But that doesn't mean the lower atmosphere cannot warm from adding more greenhouse gases, because at the same time they also cool the upper atmosphere]. While it is true that most of the CO2-caused warming in the atmosphere was there before humans ever started burning coal and driving SUVs, this is all taken into account by computerized climate models that predict global warming. Adding more “should” cause warming, with the magnitude of that warming being the real question. But I’m still open to the possibility that a major error has been made on this fundamental point. Stranger things have happened in science before.

8 ) Is Atmospheric CO2 Increasing? Yes, and most strongly in the last 50 years…which is why “most” climate researchers think the CO2 rise is the cause of the warming. Our site measurements of CO2 increase from around the world are possibly the most accurate long-term, climate-related, measurements in existence.

9) Are Humans Responsible for the CO2 Rise? While there are short-term (year-to-year) fluctuations in the atmospheric CO2 concentration due to natural causes, especially El Nino and La Nina, I currently believe that most of the long-term increase is probably due to our use of fossil fuels. But from what I can tell, the supposed “proof” of humans being the source of increasing CO2 — a change in the atmospheric concentration of the carbon isotope C13 — would also be consistent with a natural, biological source. The current atmospheric CO2 level is about 390 parts per million by volume, up from a pre-industrial level estimated to be around 270 ppm…maybe less. CO2 levels can be much higher in cities, and in buildings with people in them.

10) But Aren’t Natural CO2 Emissions About 20 Times the Human Emissions? Yes, but nature is believed to absorb CO2 at about the same rate it is produced. You can think of the reservoir of atmospheric CO2 as being like a giant container of water, with nature pumping in a steady stream into the bottom of the container (atmosphere) in some places, sucking out about the same amount in other places, and then humans causing a steady drip-drip-drip into the container. Significantly, about 50% of what we produce is sucked out of the atmosphere by nature, mostly through photosynthesis. Nature loves the stuff. CO2 is the elixir of life on Earth. Imagine the howls of protest there would be if we were destroying atmospheric CO2, rather than creating more of it.

11) Is Rising CO2 the Cause of Recent Warming? While this is theoretically possible, I think it is more likely that the warming is mostly natural. At the very least, we have no way of determining what proportion is natural versus human-caused.

12) Why Do Most Scientists Believe CO2 is Responsible for the Warming? Because (as they have told me) they can’t think of anything else that might have caused it. Significantly, it’s not that there is evidence nature can’t be the cause, but a lack of sufficiently accurate measurements to determine if nature is the cause. This is a hugely important distinction, and one the public and policymakers have been misled on by the IPCC.

13) If Not Humans, What could Have Caused Recent Warming? This is one of my areas of research. I believe that natural changes in the amount of sunlight being absorbed by the Earth — due to natural changes in cloud cover — are responsible for most of the warming. Whether that is the specific mechanism or not, I advance the minority view that the climate system can change all by itself. Climate change does not require an “external” source of forcing, such as a change in the sun.

14) So, What Could Cause Natural Cloud Changes? I think small, long-term changes in atmospheric and oceanic flow patterns can cause ~1% changes in how much sunlight is let in by clouds to warm the Earth. This is all that is required to cause global warming or cooling. Unfortunately, we do not have sufficiently accurate cloud measurements to determine whether this is the primary cause of warming in the last 30 to 50 years.

15) How Significant is the Climategate Release of E-Mails? While Climategate does not, by itself, invalidate the IPCC’s case that global warming has happened, or that humans are the primary cause of that warming, it DOES illustrate something I emphasized in my first book, “Climate Confusion”: climate researchers are human, and prone to bias.

16) Why Would Bias in Climate Research be Important? I thought Scientists Just Follow the Data Where It Leads Them When researchers approach a problem, their pre-conceived notions often guide them. It’s not that the IPCC’s claim that humans cause global warming is somehow untenable or impossible, it’s that political and financial pressures have resulted in the IPCC almost totally ignoring alternative explanations for that warming.

17) How Important Is “Scientific Consensus” in Climate Research? In the case of global warming, it is nearly worthless. The climate system is so complex that the vast majority of climate scientists — usually experts in variety of specialized fields — assume there are more knowledgeable scientists, and they are just supporting the opinions of their colleagues. And among that small group of most knowledgeable experts, there is a considerable element of groupthink, herd mentality, peer pressure, political pressure, support of certain energy policies, and desire to Save the Earth — whether it needs to be saved or not.

18) How Important are Computerized Climate Models? I consider climate models as being our best way of exploring cause and effect in the climate system. It is really easy to be wrong in this business, and unless you can demonstrate causation with numbers in equations, you are stuck with scientists trying to persuade one another by waving their hands. Unfortunately, there is no guarantee that climate models will ever produce a useful prediction of the future. Nevertheless, we must use them, and we learn a lot from them. My biggest concern is that models have been used almost exclusively for supporting the claim that humans cause global warming, rather than for exploring alternative hypotheses — e.g. natural climate variations — as possible causes of that warming.

19) What Do I Predict for Global Temperature Changes in the Future? I tend to shy away from long-term predictions, because there are still so many uncertainties. When pressed, though, I tend to say that I think cooling in our future is just as real a possibility as warming. Of course, a third possibility is relatively steady temperatures, without significant long-term warming or cooling. Keep in mind that, while you will find out tomorrow whether your favorite weather forecaster is right or wrong, no one will remember 50 years from now a scientist today wrongly predicting we will all die from heat stroke by 2060.

Concluding Remarks

Climate researchers do not know nearly as much about the causes of climate change as they profess. We have a pretty good understanding of how the climate system works on average…but the reasons for small, long-term changes in climate system are still extremely uncertain.

The total amount of CO2 humans have added to the atmosphere in the last 100 years has upset the radiative energy budget of the Earth by only 1%. How the climate system responds to that small “poke” is very uncertain. The IPCC says there will be strong warming, with cloud changes making the warming worse. I claim there will be weak warming, with cloud changes acting to reduce the influence of that 1% change. The difference between these two outcomes is whether cloud feedbacks are positive (the IPCC view), or negative (the view I and a minority of others have).

So far, neither side has been able to prove their case. That uncertainty even exists on this core issue is not appreciated by many scientists!

Again I will emphasize, some very smart people who consider themselves skeptics will disagree with some of my views stated above, particularly when it involves explanations for what has caused warming, and what has caused atmospheric CO2 to increase.

Unlike the global marching army of climate researchers the IPCC has enlisted, we do not walk in lockstep. We are willing to admit, “we don’t really know”, rather than mislead people with phrases like, “the warming we see is consistent with an increase in CO2″, and then have the public think that means, “we have determined, through our extensive research into all the possibilities, that the warming cannot be due to anything but CO2″.

Skeptics advancing alternative explanations (hypotheses) for climate variability represent the way the researcher community used to operate, before politics, policy outcomes, and billions of dollars got involved.

[winespius]

All the above are perfectly correct and all are good reason for caution before committing billions to a problem that doesn't exist..however. the politicians of almost all western countries will continue thier commitments to pour billions ijn tax dollars to save the planet from AGW...even now the 3 biggest Canadian provinces are figuring out how to initiate a cap and trade scheme with some us states...it won't go away regardless of the science..
