Here’s a letter sent to the UN by a distinguished list of scientists.
Dear Mr. Secretary-General,
Re: UN climate conference taking the World in entirely the wrong direction
It is not possible to stop climate change, a natural phenomenon that has affected humanity through the ages. Geological, archaeological, oral and written histories all attest to the dramatic challenges posed to past societies from unanticipated changes in temperature, precipitation, winds and other climatic variables. We therefore need to equip nations to become resilient to the full range of these natural phenomena by promoting economic growth and wealth generation.
The United Nations Intergovernmental Panel on Climate Change (IPCC) has issued increasingly alarming conclusions about the climatic influences of human-produced carbon dioxide (CO2), a non-polluting gas that is essential to plant photosynthesis. While we understand the evidence that has led them to view CO2 emissions as harmful, the IPCC’s conclusions are quite inadequate as justification for implementing policies that will markedly diminish future prosperity. In particular, it is not established that it is possible to significantly alter global climate through cuts in human greenhouse gas emissions. On top of which, because attempts to cut emissions will slow development, the current UN approach of CO2 reduction is likely to increase human suffering from future climate change rather than to decrease it.
The IPCC Summaries for Policy Makers are the most widely read IPCC reports amongst politicians and non-scientists and are the basis for most climate change policy formulation. Yet these Summaries are prepared by a relatively small core writing team with the final drafts approved line-by-line by government representatives. The great majority of IPCC contributors and reviewers, and the tens of thousands of other scientists who are qualified to comment on these matters, are not involved in the preparation of these documents. The summaries therefore cannot properly be represented as a consensus view among experts.
Contrary to the impression left by the IPCC Summary reports:
· Recent observations of phenomena such as glacial retreats, sea-level rise and the migration of temperature-sensitive species are not evidence for abnormal climate change, for none of these changes has been shown to lie outside the bounds of known natural variability.
· The average rate of warming of 0.1 to 0. 2 degrees Celsius per decade recorded by satellites during the late 20th century falls within known natural rates of warming and cooling over the last 10,000 years.
· Leading scientists, including some senior IPCC representatives, acknowledge that today’s computer models cannot predict climate. Consistent with this, and despite computer projections of temperature rises, there has been no net global warming since 1998. That the current temperature plateau follows a late 20th-century period of warming is consistent with the continuation today of natural multi-decadal or millennial climate cycling.
In stark contrast to the often repeated assertion that the science of climate change is “settled,” significant new peer-reviewed research has cast even more doubt on the hypothesis of dangerous human-caused global warming. But because IPCC working groups were generally instructed (see http://ipcc-wg1.ucar.edu/wg1/docs/wg1_timetable_2006-08-14.pdf) to consider work published only through May, 2005, these important findings are not included in their reports; i.e., the IPCC assessment reports are already materially outdated.
The UN climate conference in Bali has been planned to take the world along a path of severe CO2 restrictions, ignoring the lessons apparent from the failure of the Kyoto Protocol, the chaotic nature of the European CO2 trading market, and the ineffectiveness of other costly initiatives to curb greenhouse gas emissions. Balanced cost/benefit analyses provide no support for the introduction of global measures to cap and reduce energy consumption for the purpose of restricting CO2 emissions. Furthermore, it is irrational to apply the “precautionary principle” because many scientists recognize that both climatic coolings and warmings are realistic possibilities over the medium-term future.
The current UN focus on “fighting climate change,” as illustrated in the Nov. 27 UN Development Programme’s Human Development Report, is distracting governments from adapting to the threat of inevitable natural climate changes, whatever forms they may take. National and international planning for such changes is needed, with a focus on helping our most vulnerable citizens adapt to conditions that lie ahead. Attempts to prevent global climate change from occurring are ultimately futile, and constitute a tragic misallocation of resources that would be better spent on humanity’s real and pressing problems.
The list of signatories is below the fold.

...a distinguished list of scientists…
Nice cut-and-paste; did you notice that a full 25% of the scientists on this list are emeritus professors, i.e. retired? But I’m sure they’re on the cutting edge of research.
In other words, 75% of them are completely current and the emeritus professors possess the most experience?
Nice spin, Gordon.
it is irrational to apply the “precautionary principle” because many scientists recognize that both climatic coolings and warmings are realistic possibilities over the medium-term future.
Since when is it irrational to use precaution in decision making?
This is a conservative approach?
And that last part basically says they don’t know, any one of the TV channels can do better than that.
It would be nice to know what they mean by “medium-term future.” would it not?
Want to apply that coin toss approach to any other areas of public policy or international relations?

In other words they haven’t sold their souls for global warming research funding
The irrationality of applying the “precautionary principle” arises because in this case one cannot know if it precautionary.
The irrationality of applying the “precautionary principle” arises because in this case one cannot know if it precautionary.
So you can’t know if it is or is not, right.
Hence precaution. Get it?
When the lake freezes for the first time do you throw a rock out first to see if it cracks or maybe walk out?
Or do you just drive the pickup right on out there?
No pjr, read the letter. If you don’t know future trends, then the action proposed may in fact be harmful and hence not precautionary, get it?
The great majority of IPCC contributors and reviewers, and the tens of thousands of other scientists who are qualified to comment on these matters, are not involved in the preparation of these documents. The summaries therefore cannot properly be represented as a consensus view among experts.
And how many thousands signed this letter?
action proposed may in fact be harmful and hence not precautionary
And how would any of this proposed action be harmful to our climate?
And where is that stated in the letter?
“...it is irrational to apply the “precautionary principle” because many scientist recognize that both climatic coolings and warmings are realistic possibilities over the medium term future.”
If one attempts to heat the globe as a precaution against cooling, but instead the globe is warming, the outcome could be harm and vice versa.
In other words, 75% of them are completely current and the emeritus professors possess the most experience?
Sure, 75% appear to be current in various capacities, ranging from an adjunct (i.e. temporary) professor of mechanical engineering to a “Professor for Innovation and Technology Management, Production Management and Logistics,” whatever that is. A thin minority specialize in climate science.
And the 25% who are retired? They absolutely have experience, but you’d agree that most are decades past their days of active research.
If one attempts to heat the globe as a precaution against cooling, but instead the globe is warming, the outcome could be harm and vice versa.
So by reducing the unnatural levels of CO2 created by industrialization and development we would be allowing the earth and its climate to return to it natural and inevitable cycles referred to in the letter and not influence any natural heating and cooling cycles.
Yep, I get it.
Oh and Owen singularly objective reaction to 113 year old data was;
And exactly how many thermometers were there in 1895 throughout the world? And how accurately were the records kept?
And then you steadfastly accept this;
The average rate of warming of 0.1 to 0. 2 degrees Celsius per decade recorded by satellites during the late 20th century falls within known natural rates of warming and cooling over the last 10,000 years.
My reaction is, exactly how many thermometers were there in 8000 BC throughout the world? And how accurately were the records kept? And by whom?
You’re beginning to grasp the concept of error, pjr. you’ve become a global warming sceptic.
Seems like global warming is getting debunked faster and faster. The believers won’t give up just as they believe that welfare is still good and high taxes are a good thing.
Seems like global warming is getting debunked faster and faster.
Are you serious? According to what, the conservative blogs you visit? Op ed pieces? Jesus, no wonder the United States is ranked so poorly in science.
I’d wager that you’ve never bothered to look at the basic science, so here goes. Let’s focus on just warming caused by the gas you burn in your car. A gallon of gasoline weighs 6.2 pounds, consisting mostly of carbon, plus some hydrogen. When the gas burns, each carbon atom combines with two atoms of oxygen, resulting in 19.8 pounds of carbon dioxide in the atmosphere.
Just in America, we burn about 120 billion gallons of gas every year. That results in two trillion, three hundred seventy-six billion pounds of carbon dioxide.
The earth naturally recycles about 225 billion tons of carbon dioxide each year from processes like respiration, decay, and fires. That means that just through burning gas we’re adding 5.5 billion tons to a formerly closed system. That’s a small but significant amount.
So what does that added carbon dioxide do? Carbon dioxide absorbs and traps more heat than oxygen and nitrogen, so when there’s more of it in the atmosphere, more heat is absorbed and less reflected into space. It’s elementary.
That’s the simple overview. The past 20 years have been spent refining the science and what we know. We now understand global warming better than virtually any other environmental mechanism on the planet. The only reason there’s a “debate” is because there are various political, business and religious reasons for people to feel threatened by the implications of global warming.
Discuss.
Gordon, I’ve noted that in general there is an inverse correlation between the fervor of global warming alarmists and the number of science courses they voluntarily took. That’s why Hollywood is such a big fan - unencumbered by any scientific knowledge. At one time Milwaukee was covered by a mile of ice and then it all melted without a single SUV to blame. Hmmmm. How did that happen? My big problem with this hysteria is that obsessing about CO2 takes our eye off of REAL environmental problems such as heavy metals, PCBs, etc. I’m still waiting for an apology from Al Gore for his help in destroying the US nuclear industry.
Gordon, I’ve noted that in general there is an inverse correlation between the fervor of global warming alarmists and the number of science courses they voluntarily took.
Are you saying that the climatologists who overwhelmingly say that climate change is real and is the result of human activity didn’t actually take any science classes? You sure about that?
At one time Milwaukee was covered by a mile of ice and then it all melted without a single SUV to blame. Hmmmm. How did that happen?
Charlie, no one is saying that the Earth’s climate is perfectly static. It’s been hotter in the past, and it’s been colder in the past. The science takes this into consideration. Global warming basically describes a very fast warming attributable to human activity, not any larger natural cycles.
Simply elegant.

This isn’t about science any longer. It’s about the anthropogenic global warming crowd saving face. Temp’s have been going down. The data to show that their doom & gloom scenarios is bunk is out there. But before enough momentum comes along to thwart their efforts, they must get global legislation passed.
The reason: so they can claim victory when nothing happens (and believe me, none of these ridiculous scenarios they portray will happen).
In 2050, when we will have seen another half-century come out just as average as the last one, they have to be able to claim it was because of them. Granted, most of them (including most of us on this comment space) probably will not be around in 2050, the true basis for their panic will be: Marxist doctrine.
As long as they can Karl’s spirit alive through this kind of fear mongering they can die at peace with themselves.
(And no, I’m not calling all the commenters here a bunch of Marxists for believing in global warming. I’m calling the research grant/funding whores formerly known as “scientists” and über-wealthy world elites who push this agenda and wish to hold onto their power, popularity, and money the Marxists. Everyone around here touting this stuff is unfortunately just gullible - or too proud to admit when they’ve been duped. Nothing wrong with that; we’ve all done it.)

I’m calling the research grant/funding whores formerly known as “scientists” and über-wealthy world elites who push this agenda and wish to hold onto their power, popularity, and money the Marxists.
My wife is among those “funding whores,” David. So are most of her friends and colleagues. And you know what? You’re a moron. If she and her fellow researchers simply wanted more money, they would jump ship to Monsanto and double their salaries overnight. They wouldn’t have to rely on donations and paltry grants that corporations dole out mainly to benefit public relations. “Push this agenda?” What agenda? That’s like saying cancer researchers have an agenda against carcinogens! Or that tire-makers have an agenda against skidding. You’re politicizing it, not the scientists just doing a job.
The data to show that their doom & gloom scenarios is bunk is out there.
I love it. The “data.” What data? You can’t make a solid point, so you point to…nothing. How well do you know the science? How many primary sources have you checked out? How “research grant/funding whores” do you know, David? How many scientists? How many teachers? What do you read beyond the self-affirming blog posts that support what you already think?
Sorry this pisses me off. I know too many scientists and teachers and researchers, both friends and family, and for years I’ve been reading this bizarre attack on the only people who actually dig into the science rather than just spewing opinion, so yeah, when people come along and generalize and spout complete idiocy, it strikes a nerve.
So what does that added carbon dioxide do? Carbon dioxide absorbs infra red radiation of 1-10 micrometers wavelength, whereas oxygen and nitrogen are diathermanous. The IR absorption of carbon dioxide overlaps the IR absorption of water anywhere from 88-95% of the total radiant absorption between 1 and 15 micrometers (at 1 atmosphere), depending on relative concentrations and temperature. The vapour pressure of water is some 125 times the partial pressure of carbon dioxide at 15 deg.C (assuming 320 ppm carbon dioxide in the atmosphere), so at saturation water vapour accounts for 97- 98 percent of all radiant heat that is not re-radiated to space. This is at the ideal case of a diathermanous stratosphere, which is almost certainly not true. In fact it is possible for more heat to be re-radiated in the presence of carbon dioxide than without it, and here’s how: the local evaporation rate of ground water can be decreased (assuming radiant heat exchange with the night shy) in the presence of carbon dioxide in the atmosphere, by absorbing the heat loss by radiation of the water on the ground. This reduces humidity and therefore reduces total radiation absorbed by water in the atmosphere.
That’s a simple view of some of the phenomena that can occur. The past 20 years have been spent refining the science and what we know. We now understand global warming about as well as we did when we realized, forty years ago, that the increase in atmospheric temperature that results from water vapour in the atmosphere is somewhere between 10 and thirty degrees Celsius, and the amount of increase depends on the initial conditions. There is no way to place any global value on it. Nor is there any way to assign the possible contribution of carbon dioxide to that increase – as natural warming phenomena are responsible for 2-10 times the temperature variation that carbon dioxide is. The only reason there’s a “debate” is because no measurement techniques could possibly discern any increase in local or global temperature even if all natural variations were accounted for. The point being 1) to the post-modernist, the effect does not exist if it cannot be measured, even in theory or 2) to the pragmatist, there are far more important things to worry about.
