McKitrick does it again; first he kills the hockey stick graph and now he puts the kibosh on AGW.



Global Warming Data Affected By Land-Use Change, Study Says

December 04, 2007 - News Release
Land-use modifications for urbanization and agriculture have affected climate change data more than previously thought, according to new research by a University of Guelph professor.
In a paper published online this week in the Journal of Geophysical Research-Atmosphere, economics professor Ross McKitrick says the resulting discrepancies may be leading to an overstatement of the role of greenhouse gases in the atmosphere. In fact, the study concludes that skewed data could account for as much as half the post-1980 warming trend over land.
"Much of the temperature data used by the Intergovernmental Panel on Climate Change (IPCC) to measure global warming comes from places where people have modified the land surface for economic activity, as well as from low-income countries where there are few resources for maintaining continuous climate records," McKitrick said.
"To identify climate changes due to greenhouse gases, scientists have to make adjustments to the data to remove biases created by these kinds of influences."
For the study, McKitrick and co-author Patrick Michaels, a meteorologist with the Cato Institute, a non-profit public research centre in Washington, D.C., examined how the pattern of warming and cooling trends around the world compares with the patterns of population growth, economic development, coal consumption and other socio-economic indicators.
According to standard assumptions, trends in adjusted global climate data should not be correlated with patterns of economic activity, McKitrick said.
“But we found large, statistically significant correlations exist, indicating that the climate ‘signal’ in a commonly used scientific database remains contaminated with sources of bias that were supposed to be removed at the adjustment stage.”
The researchers applied a series of tests to check their results. For example, they looked at data measured by weather satellites in the lower atmosphere.
"We found that the correlations with economic activity pretty much vanishes even though the effects of greenhouse gases should be similar at the two layers," McKitrick said. "That tells us there is a unique problem in the surface data.”
They also determined that the effects were especially strong in regions where economic growth is faster, which also points to local socio-economic development as the culprit, he said.
The scientists used their results to simulate what worldwide trends would look like if the contamination were removed.
“Our estimate is that the measured warming over land since 1980 would go down by nearly half, which implies that these data problems are larger than is currently supposed," McKitrick said.
This is the second study on this topic by the two researchers. In 2004, they examined part of the Earth’s land surface and found similar results. For the new study, they extended their coverage to all available land regions.
McKitrick said the findings may affect current interpretations of global climate data, including how much warming is happening and what is causing it.
"The IPCC and other users of climate data need to consider the possibility that the basic data being used to study global warming are contaminated.”

The Science of Gore's Nobel
[FONT=Garamond, Times]What if everyone believes in global warmism only because everyone believes in global warmism?[/FONT]
[FONT=Verdana, Times]
BY HOLMAN W. JENKINS JR.
Wednesday, December 5, 2007 12:01 a.m. EST

The Nobel Committee might as well have called it Al Gore's Inner Peace Prize, given the way it seems designed to help him disown his lifelong ambition to become president in favor of a higher calling, as savior of a planet.
The media will be tempted to blur the fact that his medal, which Mr. Gore will collect on Monday in Oslo, isn't for "science." In fact, a Nobel has never been awarded for the science of global warming. Even Svante Arrhenius, who first described the "greenhouse" effect, won his for something else in 1903. Yet now one has been awarded for promoting belief in manmade global warming as a crisis.
How this honor has befallen the former Veep could perhaps be explained by another Nobel, awarded in 2002 to Daniel Kahneman for work he and the late Amos Tversky did on "availability bias," roughly the human propensity to judge the validity of a proposition by how easily it comes to mind.
Their insight has been fruitful and multiplied: "Availability cascade" has been coined for the way a proposition can become irresistible simply by the media repeating it; "informational cascade" for the tendency to replace our beliefs with the crowd's beliefs; and "reputational cascade" for the rational incentive to do so.
Mr. Gore clearly understands the game he's playing, judging by his resort to such nondispositive arguments as: "The people who dispute the international consensus on global warming are in the same category now with the people who think the moon landing was staged in a movie lot in Arizona."
Here's exactly the problem that availability cascades pose: What if the heads being counted to certify an alleged "consensus" arrived at their positions by counting heads?


It may seem strange that scientists would participate in such a phenomenon. It shouldn't. Scientists are human; they do not wait for proof; many devote their professional lives to seeking evidence for hypotheses (especially well-funded hypotheses) they've chosen to believe.

Less surprising is the readiness of many prominent journalists to embrace the role of enforcer of an orthodoxy simply because it is the orthodoxy. For them, a consensus apparently suffices as proof of itself.
With politicians and lobbyists, of course, you are dealing with sophisticated people versed in the ways of public opinion whose very prosperity depends on positioning themselves via such cascades. Their reactions tend to be, for that reason, on a higher intellectual level.
Take John Dingell. He told an environmental publication last year that the "world . . . is great at having consensuses that are in great error." Yet he turned around a few months later and introduced a sweeping carbon tax bill, which would confront Congress more frontally than Congress cares to be confronted with a rational approach to climate change if Congress really believes human activity is responsible.
Mr. Dingell is no fool. Is he merely trying to embarrass those who offer fake cures for climate change at the expense of out-of-favor industries such as Mr. Dingell's beloved Detroit?
Take Vinod Khosla, a venture capitalist working with Kleiner Perkins, a firm Mr. Gore joined last month to promote alternative energy investments. Mr. Khosla told a recent Senate hearing: "One does not need to believe in climate change to support climate change legislation. . . . Many executives would prefer to deal with known legislation even if unwarranted."
Mr. Khosla is no fool either. His argument is that the cascade itself is a reason that politicians can gain comfort by getting aboard his agenda.


Now let's suppose a most improbable, rhapsodic lobbying success for Mr. Gore, Mr. Khosla and folks on their side of the table--say, a government mandate to replace half the gasoline consumed in the U.S. with a carbon-neutral alternative. This would represent a monumental, $400 billion-a-year business opportunity for the green energy lobby. The impact on global carbon emissions? Four percent--less than China's predicted emissions growth over the next three or four years.

Don't doubt that this is precisely the chasm that keeps Mr. Gore from running for president. He could neither win the office nor govern on the basis of imposing the kinds of costs supposedly necessary to deal with an impending "climate crisis." Yet his credibility would become laughable if he failed to insist on such costs. How much more practical, then, to cash in on the crowd-pleasing role of angry prophet, without having to take responsibility for policies that the public will eventually discover to be fraudulent.
Public opinion cascades are powerful but also fragile--liable to be overturned in an instant when new information comes along. The current age of global warming politics will certainly end with a whimper once a few consecutive years of cooling are recorded. Why should we expect such cooling? Because the forces that caused warming and cooling in the past, before the advent of industrial civilization, are still at work.
No, this wouldn't prove or disprove a human role in warming, only that climate is variable and subject to complicated influences. But it would also eliminate the large incentive for politicians to traffic in doom-laden predictions--because such predictions would no longer command media assent and would cease to function as levers to redistribute resources.
Mr. Gore would have to find a new job. Mr. Jenkins is a member of The Wall Street Journal's editorial board. His column appears in the Journal on Wednesdays.

The Greenest Hypocrites of 2007

Thursday, December 06, 2007
By Steven Milloy


Green has traditionally been the color of the deadly sin of envy. But this year, a trendy upstart mounted a serious challenge to envy’s claim.

Here are green hypocrisy’s top 10 poster children for 2007.

1. Al Gore’s Inconvenient Lifestyle. While the former veep and nouveau-$100 millionaire jets around the world squawking about the “planet having a fever” and demanding that we all lower our standard of living, his own personal electricity use is 20 times the national average, including an indoor pool costing $500/month to heat.

While Gore deflected criticism of his inconvenient electric bill during March congressional testimony by saying he purchased “green” electricity, the truth is, he didn’t start doing so until 2007.

2. Google’s Sky Pig. A photo-op of Google founders Larry Page and Sergey Brin plugging-in a hybrid car was part of the search engine giant’s June announcement promising carbon neutrality by 2008. But how this PR-fluff squares with the so-called “Google party jet” — Page and Brin’s gargantuan personal Boeing 767, which burns about 1,550 gallons/hour — is any one’s guess.

3. RFK Jr. Tilts at Windmills. Outspoken global warming activist Robert F. Kennedy Jr. recently railed against coal-produced electricity because “climate change is the most urgent threat to our collective survival.”

Meanwhile, Kennedy vigorously campaigns against a proposed Cape Cod wind farm that would generate CO2-free electricity because it would “impoverish the experience of millions of tourists and residents and fishing families who rely on the sound's unspoiled bounties.” Unmentioned in Kennedy’s tirades, however, is the windmill’s unfortunate proximity to his family’s famed Hyannis Port compound.

4. The U.N.’s ‘Bali High’. Early December will witness 10,000 climateers descending upon the paradisiacal island resort of Bali for the 13th annual U.N. global warming meeting. The reason for much jet and limo travel — and other prodigious greenhouse gas generating activity associated with such a mega-conference — is relatively modest: setting the agenda and timeframe for a post-Kyoto treaty. Sure seems like something that could have been handled in a less carbon-intensive way — either by Internet and video conferencing or, if meeting is necessary, somewhere in North America or Europe where most key attendees are based.

5. Nancy Nukes Nukes. Supposedly concerned that “global warming and energy independence…have profound implications for our nation’s economic competitiveness, national security, environmental quality and public health,” House Speaker Nancy Pelosi created the House Select Committee on Energy Independence and Global Warming to take the congressional lead on those issues.

So who did Speaker Pelosi pick to chair the committee? None other than long-time nuclear power opponent Rep. Ed Markey, D-Mass., who appeared with anti-nuke celebrities Bonnie Raitt and Jackson Browne at an October Capitol Hill press conference to denounce legislation promoting the development of ultra-green nuclear power.

6. Every home a Superfund site? “Mercury is highly toxic to everyone, but particularly to children and developing fetuses,” says the activist group Environmental Defense, a long-time campaigner against mercury from power plant emissions and in automobile convenience lighting.

So it came as quite a surprise when the group began advocating that consumers bring the “highly toxic” mercury into their homes in the form of compact fluorescent light bulbs in order to reduce power plant CO2 emissions. CFLs are so hazardous, according to public health officials however, that special safety precautions must be taken for disposal or if the bulbs break.

7. Doesn’t everyone own a NASA scientist? In March 2007, NASA’s climate alarmist-in-chief James Hansen criticized “special interests” campaigning against climate regulation.

“By larding the campaign coffers of numerous politicians, the fossil fuel industry has succeeded in subverting the democratic principle…Until the public indicates sufficient interest, and puts pressure on political systems, special interests will continue to rule.”

Though Hansen poses as a humble civil servant, it recently came to light that his alarmist efforts have been bankrolled by leftist billionaire and MoveOn.org sugar-daddy George Soros. Doesn’t Soros qualify as a “special interest,” Dr. Hansen?

8. Like a Virgin’s Carbon Footprint. London’s Daily Mail reported (“What planet are they on?, July 7) on the climate consciousness of Madonna and other Live Earth performers.

“[T]he pop stars headlining the concerts are the absolute antithesis of the message they promote with Madonna leading the pack of the worst individual rock star polluters in the world… Madonna alone has an annual carbon footprint of 1,018 tons… the average Briton produces just 10 tons… [her] Confessions tour last year produced 440 tons of carbon pollution in just four months, simply in flights between venues.”

That’s one small footprint for the average Brit, but one giant footprint for celebrity-kind.

9. The NBC Poppycock. NBC-Universal kicked-off of its “Green is Universal” initiative by dimming the studio lights — but not two giant video screens and advertisements — during a break in the Nov. 4 Cowboys-Eagles game.

Candle-lit host Bob Costas then cut to video of Today show personalities Matt Lauer, Al Roker and Ann Curry reporting about climate change from the Arctic, Amazon and Antarctic, respectively. None gave even a nod to the energy-hogging effort required to send them and crews to do such pointless broadcasts from exotic locales.

10. California’s Hypocritenator. Gov. Arnold Schwarzenegger declared in June 2005 that, “California will be a leader in the fight against global warming…the time for action is now.”

But just two years later, the Los Angeles Times reported that state efforts had been derailed by the governor’s mismanagement and deceit. Schwarzenegger even fired the state’s chief regulator for refusing to limit the number of greenhouse gas regulations. Columnist Debra Saunders noted that, “Schwarzenegger boasts that he is a world leader in the fight against global warming — but his advocacy shouldn't keep him from flying in private jets or driving a Hummer.”

The one thing these honorees all have in common is that their real-life actions belie their carefully crafted green public images. If they don’t take their commitment seriously, why should you?

[FONT=Arial, helvetica]Dishonest political tampering with the science on global warming [/FONT]
[FONT=Arial, Helvetica]- Wednesday, December 05, 2007[/FONT] Christopher Monckton, Denpasar, Bali
As a contributor to the IPCC's 2007 report, I share the Nobel Peace Prize with Al Gore. Yet I and many of my peers in the British House of Lords - through our hereditary element the most independent-minded of lawmakers - profoundly disagree on fundamental scientific grounds with both the IPCC and my co-laureate's alarmist movie An Inconvenient Truth, which won this year's Oscar for Best Sci-Fi Comedy Horror.

Two detailed investigations by Committees of the House confirm that the IPCC has deliberately, persistently and prodigiously exaggerated not only the effect of greenhouse gases on temperature but also the environmental consequences of warmer weather.
My contribution to the 2007 report illustrates the scientific problem. The report's first table of figures - inserted by the IPCC's bureaucrats after the scientists had finalized the draft, and without their consent - listed four contributions to sea-level rise. The bureaucrats had multiplied the effect of melting ice from the Greenland and West Antarctic Ice Sheets by 10.
The result of this dishonest political tampering with the science was that the sum of the four items in the offending table was more than twice the IPCC's published total. Until I wrote to point out the error, no one had noticed. The IPCC, on receiving my letter, quietly corrected, moved and relabeled the erroneous table, posting the new version on the internet and earning me my Nobel prize.
The shore-dwellers of Bali need not fear for their homes. The IPCC now says the combined contribution of the two great ice-sheets to sea-level rise will be less than seven centimeters after 100 years, not seven meters imminently, and that the Greenland ice sheet (which thickened by 50 cm between 1995 and 2005) might only melt after several millennia, probably by natural causes, just as it last did 850,000 years ago. Gore, mendaciously assisted by the IPCC bureaucracy, had exaggerated a hundredfold.
Recently a High Court judge in the UK listed nine of the 35 major scientific errors in Gore's movie, saying they must be corrected before innocent schoolchildren can be exposed to the movie. Gore's exaggeration of sea-level rise was one.
Others being peddled at the Bali conference are that man-made "global warming" threatens polar bears and coral reefs, caused Hurricane Katrina, shrank Lake Chad, expanded the actually-shrinking Sahara, etc.
At the very heart of the IPCC's calculations lurks an error more serious than any of these. The IPCC says: "The CO2 radiative forcing increased by 20 percent during the last 10 years (1995-2005)." Radiative forcing quantifies increases in radiant energy in the atmosphere, and hence in temperature. The atmospheric concentration of CO2 in 1995 was 360 parts per million. In 2005 it was just 5percent higher, at 378 ppm. But each additional molecule of CO2 in the air causes a smaller radiant-energy increase than its predecessor. So the true increase in radiative forcing was 1 percent, not 20 percent. The IPCC has exaggerated the CO2 effect 20-fold.
Why so large and crucial an exaggeration? Answer: the IPCC has repealed the fundamental physicalthe Stefan-Boltzmann equation - that converts radiant energy to temperature. Without this equation, no meaningful calculation of the effect of radiance on temperature can be done. Yet the 1,600 pages of the IPCC's 2007 report do not mention it once.
The IPCC knows of the equation, of course. But it is inconvenient. It imposes a strict (and very low) limit on how much greenhouse gases can increase temperature. At the Earth's surface, you can add as much greenhouse gas as you like (the "surface forcing"), and the temperature will scarcely respond.
That is why all of the IPCC's computer models predict that 10km above Bali, in the tropical upper troposphere, temperature should be rising two or three times as fast as it does at the surface. Without that tropical upper-troposphere "hot-spot", the Stefan-Boltzmann law ensures that surface temperature cannot change much.
For half a century we have been measuring the temperature in the upper atmosphere - and it has been changing no faster than at the surface. The IPCC knows this, too. So it merely declares that its computer predictions are right and the real-world measurements are wrong. Next time you hear some scientifically-illiterate bureaucrat say, "The science is settled", remember this vital failure of real-world observations to confirm the IPCC's computer predictions. The IPCC's entire case is built on a guess that the absent hot-spot might exist.
Even if the Gore/IPCC exaggerations were true, which they are not, the economic cost of trying to mitigate climate change by trying to cut our emissions through carbon trading and other costly market interferences would far outweigh any possible climatic benefit.
The international community has galloped lemming-like over the cliff twice before. Twenty years ago the UN decided not to regard AIDS as a fatal infection. Carriers of the disease were not identified and isolated. Result: 25 million deaths in poor countries.
Thirty-five years ago the world decided to ban DDT, the only effective agent against malaria. Result: 40 million deaths in poor countries. The World Health Organization lifted the DDT ban on Sept. 15 last year. It now recommends the use of DDT to control malaria. Dr. Arata Kochi of the WHO said that politics could no longer be allowed to stand in the way of the science and the data. Amen to that.
If we take the heroically stupid decisions now on the table at Bali, it will once again be the world's poorest people who will die unheeded in their tens of millions, this time for lack of the heat and light and power and medical attention which we in the West have long been fortunate enough to take for granted.
If we deny them the fossil-fuelled growth we have enjoyed, they will remain poor and, paradoxically, their populations will continue to increase, making the world's carbon footprint very much larger in the long run.
As they die, and as global temperature continues to fail to rise in accordance with the IPCC's laughably-exaggerated predictions, the self-congratulatory rhetoric that is the hallmark of the now-useless, costly, corrupt UN will again be near-unanimously parroted by lazy, unthinking politicians and journalists who ought to have done their duty by the poor but are now - for the third time in three decades - failing to speak up for those who are about to die.
My fellow-participants, there is no climate crisis. The correct policy response to a non-problem is to have the courage to do nothing. Take courage! Do nothing, and save the world's poor from yet another careless, UN-driven slaughter. The writer is an international business consultant specializing in the investigation of scientific frauds.

Yes...the Kennedy's and Cape Wind. The leaders in the fight of alternative fuel providing it does not effect their summer yachting off Hyannis. That is where the wind farm is going to go and the Kennedy's are suddenly against clean power...at least in their back yard and they consider the waters off Hyannis "THEIR" back yard!

A convenient £50m for green Gore



Steven Swinford


WHO would have thought that saving the planet could be such a lucrative business? Al Gore, the former US vice-president turned environmental campaigner, has made more than £50m in just seven years from his books, speeches and shrewd investments in technology and green ventures.
Gore, 59, a failed presidential candidate, has already reinvented himself from the nearly man of American politics into the first global green celebrity. This week he will pick up the Nobel peace prize in Oslo before flying to Bali to take centre stage at the United Nations climate change conference.
Today Gore commands between £50,000 and £85,000 a speech, holds stock options in Google worth £15m and has made as much as £4m from advances on his book deals. He is also advising a US venture capital company on how to invest a $600m green technology fund.
He has come a long way since losing the 2000 presidential election to George W Bush when, according to official documents, Gore was worth just £1m. His biggest assets were his two homes in Nashville, Tennessee, and Arlington, Virginia, valued at £375,000, and £500,000 invested in oil company shares.
But rather than dwell on his disappointment, Gore threw himself into the world of business.
Joel Hyatt, who chaired the democratic finance committee during the 2000 election and is now Gore’s business partner, said: “Al’s bouncing back from that experience has been quite extraordinary. It’s hard to move on from something like that but the fact he did is an incredible testament to his character.”
Gore began by joining Google as an adviser in 2001. At the time it was a relatively new and rising internet search engine. In March 2003 he joined the board of Apple, where he holds stock options that are now valued at about £3m. According to Hyatt, his interest in technology is long-standing. “Al has always had a real mind for gadgets and technology. He is a real geek in that regard.”
Gore has also invested a significant proportion of his wealth in Current TV, a cable channel on which viewers can broadcast their own video clips. It has 38m subscribers in the US and is now being shown in 8m homes in Britain.
At the same time Gore’s interest in green issues was coming to the fore, and his rise as a climate-change celebrity has proved highly lucrative.
Since the release of his documentary film An Inconvenient Truth, Gore has given 150 speeches a year.
His spokesman emphasised, however, that Gore waives his lecture fees for charities and schools and gives a proportion of his income to the Alliance for Climate Protection, of which he is chairman.
A contract for one of his speaking arrangements, released by the University of California under freedom of information requirements, reveals that Gore demands first class travel and accommodation and £500 a day for meals, phone calls and other expenses.
The contract stipulates that Gore’s car from the airport should be “a sedan, not a sports utility vehicle”.
Gore has written nine books, with advances worth between £3m and £4.5m, and has another planned for next year.
In 2003 he sold MetWest, an asset management firm he had started two years earlier, picking up a payout rumoured to be another £15m. In April 2004 he used the money to co-found Generation Investment Management, a London-based company that specialises in “sustainable” investments.
Today it manages more than £500m of assets, ranging from Novo Nordisk, a Danish drug maker, to Whole Foods Market, an organic retailer.
This month Gore joined the board of Kleiner Perkins Caulfield & Byers, venture capitalists whose investment helped fuel the dotcom boom and fund companies such as Amazon. Kleiner is now going green and has started a £300m fund for technologies that aim to reduce carbon dioxide emissions.
It has already invested in 26 companies that make everything from electric cars to microbes that scrub oil wells.

I guess the fact that there's been warming and cooling on this planet for thousands of years doesn't play into any of this?? While the planet may be warming, chances are it's because we had an era of "ice" so now we're swinging the other way...and, eventually, it'll go back to being ice etc., etc. ??????

Just askin'

That's not to say we shouldn't be responsible in our care of "Mother earth" but to say categorically that we're to blame seems a bit...oh, I don't know - just sounds like a lot of "jingle" in some individual/corporate pockets that the average joe won't see, and, in fact, will pay through the nose for.

What does it matter if the cooling is natural or manmade?

Its a little like complaining if a killer virus is natural or man made.

Regardless of who is to blame (if anyone) people will die if it is left unchecked, people are starting to now.

Regardless of what caused it, we have been quite aware of how to cause global cooling for some time.

Global cooling? I thought the worry was global warming. Of course it matters if climate change is man made or not because if it is man made then it is more likely we will be able to influnece the change. That said the cost of trying to change the weather must always be weighed against the cost of adaptation.

Since I wasn't participating in any debate on that particular paste, I only used the recorder (one of thousands such) as one example why I am extremely skeptical of it. As has been explained clearly already.
One of thousands yes, one of thousands placed like that, well one station doesn't prove that.
No. Neither do the rest of the thousands that are improperly used. And I don't know if they study used them at all. I merely posted that as an example of why I am skeptical of such studies. As I have already stated repeatedly. You must get it by now.

Who brought Mann into this again? Oh that's right it was you:roll:
Well, you did ask where you said that was a strawman. Merely refreshing your memory.
What you presented is fringe work, which hasn't passed the litmus test. I could actually post some studies that are legitimate if you'd like. That would be better suited for a discussion on the process of peer review.
It's called facts. Evidence. Reality.
It's reporting. Not a study. I never claimed it was a study. The aim wasn't a new investigation, it's the data from temperature measurements.
And that's what makes me skeptical. I've seen the accuracy of some of those measuring stations. Not saying they were used in that "reporting" (although I can't think where else they would get that data.)

Yes, I know they cause drops. They can also cause increases. In the past when there were faster rises and falls, like you said,but they were conditions which aren't comparable to ours. Active volcanism, changes in Milankovitch cycles, and solar activity. They do not compare to our present situation. There is very little volcanism, we're in between the extreme ends of the Milankovitch cycles, and solar activity has had a negligible effect since the 50's. So unless there is some other cause to the large swings in the past, that we don't know about, the science leads us to what we know currently. Greenhouse gases increase temperature. Greenhouse gases are increasing. The Earth doesn't have the capacity to remove all of our emissions. The result is warming.

It's a positive forcing. That's straight physics, and has been around for well over a hundred years, going all the way back to Tyndall.
CO2 is a very effective greenhouse gas, but the first 20 ppm does 3 degrees of the warming. It takes a further 260 ppm to warm another 3 degrees. Doubling the amount again would have negligible effect, as the narrow infrared frequencies are absorbed, further CO2 in the atmosphere will find little available frequencies to absorb. This is well established science. I know you've claimed (as have other alarmists) that recent solar activity is inadequate to cause the current warming, but others disagree, and since the temp fluctuations are pretty much in lockstep with solar activities, it would appear that solar activity is indeed the cause of warming. The bumblebee flies anyway.

Dr. Bob Carter explains it very well in 4 parts here.

They sure do care about the truth, don't they.

The United Nations has rejected all attempts by a group of dissenting scientists seeking to present information at the climate change conference taking place in Bali, Indonesia. The International Climate Science Coalition (ICSC) has been denied the opportunity to present at panel discussions, side events, and exhibits; its members were denied press credentials. The group consists of distinguished scientists from Africa, Australia, India, New Zealand, the United Kingdom, and the United States.
The scientists, citing pivotal evidence on climate change published in peer-reviewed journals, have expressed their opposition to the UN’s alarmist theory of anthropogenic global warming.

You'd find this article interesting, Ton.

Scientists who attribute warming to greenhouse gases argue that their climate models cannot reproduce the surface trends from natural variability alone. They then attribute it to greenhouse gases, since (they assume) all other human influences have been removed from the data by the adjustment models. If that has not happened, however, they cannot claim to be able to identify the role of greenhouse gases. Despite the vast number of studies involved, and the large number of contributors to the IPCC reports, the core message of the IPCC hinges on the assumption that their main surface climate data set is uncontaminated. And by the time they began writing the recent Fourth Assessment Report, they had before them a set of papers proving the data are contaminated. [...] Confronted with published evidence of an anthropogenic (but non-greenhouse) explanation for warming, they dismissed it with an unproven conjecture of natural causes. Who's the "denialist" now?

And that's what makes me skeptical. I've seen the accuracy of some of those measuring stations. Not saying they were used in that "reporting" (although I can't think where else they would get that data.)

What you or I think is irrelevant. What matters is the proof. I think we can agree on that.:lol:

CO2 is a very effective greenhouse gas, but the first 20 ppm does 3 degrees of the warming. It takes a further 260 ppm to warm another 3 degrees. Doubling the amount again would have negligible effect, as the narrow infrared frequencies are absorbed, further CO2 in the atmosphere will find little available frequencies to absorb. This is well established science. I know you've claimed (as have other alarmists) that recent solar activity is inadequate to cause the current warming, but others disagree, and since the temp fluctuations are pretty much in lockstep with solar activities, it would appear that solar activity is indeed the cause of warming. The bumblebee flies anyway.

Dr. Bob Carter explains it very well in 4 parts here.

We've discussed this before, as to the absorption bands. The atmosphere is not a homogeneous system. The absorption bands are narrow closer to ground, but they are broad in the upper reaches of the atmosphere. This relates to the pressure, and this so happens to be where radiant energy determines the heat balance of Earth. Those bands are not saturated.

We have a perfectly good tool to display this fact. It's the NASA DSCOVR satellite sitting in a secure facility. It was built to measure the energy reaching the sunlit side of Earth every day, and to measure how much is re-emitted out of our atmosphere. It seems it maybe destroyed, as top level politics and funding 'priorities' at NASA have it on the block, despite requests from other bodies like the NOAA to purchase and finance the launch of the crucial satellite.

May I suggest that if the absorption is different at different altitudes it is due to gas stratification. That is the absorption is different at different altitudes because the gas composition of the atmosphere is different at different altitudes and not because the pressure change in the earth atmosphere has any significant effect on the absorption characteristics of CO2.

Visible light is typically absorbed because of vibrational modes in the molecule. These wave functions are only significantly altered when there is a large amount of pressure like in a sun. The effect is called pressure broadening.
