Statement of Patrick Moore, Ph.D. Before the Senate Environment and Public Works Committee, Subcommittee on Oversight
February 25, 2014
Natural Resource Adaptation: Protecting ecosystems and economies
Chairman Whitehouse, Ranking Member Inhofe, and members of the Committee. Thank you for the opportunity to testify at todays hearing.
In 1971, as a PhD student in ecology I joined an activist group in a church basement in Vancouver Canada and sailed on a small boat across the Pacific to protest US Hydrogen bomb testing in Alaska. We became Greenpeace.
After 15 years in the top committee I had to leave as Greenpeace took a sharp turn to the political left, and began to adopt policies that I could not accept from my scientific perspective. Climate change was not an issue when I abandoned Greenpeace, but it certainly is now.
There is no scientific proof that human emissions of carbon dioxide (CO2) are the dominant cause of the minor warming of the Earths atmosphere over the past 100 years. If there were such a proof it would be written down for all to see. No actual proof, as it is understood in science, exists.
The Intergovernmental Panel on Climate Change (IPCC) states: It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century. (My emphasis)
Extremely likely is not a scientific term but rather a judgment, as in a court of law. The IPCC defines extremely likely as a 95-100% probability. But upon further examination it is clear that these numbers are not the result of any mathematical calculation or statistical analysis. They have been invented as a construct within the IPCC report to express expert judgment, as determined by the IPCC contributors.
These judgments are based, almost entirely, on the results of sophisticated computer models designed to predict the future of global climate. As noted by many observers, including Dr. Freeman Dyson of the Princeton Institute for Advanced Studies, a computer model is not a crystal ball. We may think it sophisticated, but we cannot predict the future with a computer model any more than we can make predictions with crystal balls, throwing bones, or by appealing to the Gods.
Perhaps the simplest way to expose the fallacy of extreme certainty is to look at the historical record. With the historical record, we do have some degree of certainty compared to predictions of the future. When modern life evolved over 500 million years ago, CO2 was more than 10 times higher than today, yet life flourished at this time. Then an Ice Age occurred 450 million years ago when CO2 was 10 times higher than today. There is some correlation, but little evidence, to support a direct causal relationship between CO2 and global temperature through the millennia. The fact that we had both higher temperatures and an ice age at a time when CO2 emissions were 10 times higher than they are today fundamentally contradicts the certainty that human-caused CO2 emissions are the main cause of global warming.
Today we remain locked in what is essentially still the Pleistocene Ice Age, with an average global temperature of 14.5°C. This compares with a low of about 12°C during the periods of maximum glaciation in this Ice Age to an average of 22°C during the Greenhouse Ages, which occurred over longer time periods prior to the most recent Ice Age. During the Greenhouse Ages, there was no ice on either pole and all the land was tropical and sub-tropical, from pole to pole. As recently as 5 million years ago the Canadian Arctic islands were completely forested. Today, we live in an unusually cold period in the history of life on earth and there is no reason to believe that a warmer climate would be anything but beneficial for humans and the majority of other species. There is ample reason to believe that a sharp cooling of the climate would bring disastrous results for human civilization.
Moving closer to the present day, it is instructive to study the record of average global temperature during the past 130 years. The IPCC states that humans are the dominant cause of warming since the mid-20th century, which is 1950. From 1910 to 1940 there was an increase in global average temperature of 0.5°C over that 30-year period. Then there was a 30-year pause until 1970. This was followed by an increase of 0.57°C during the 30-year period from 1970 to 2000. Since then there has been no increase, perhaps a slight decrease, in average global temperature. This in itself tends to negate the validity of the computer models, as CO2 emissions have continued to accelerate during this time.
The increase in temperature between 1910-1940 was virtually identical to the increase between 1970-2000. Yet the IPCC does not attribute the increase from 1910- 1940 to human influence. They are clear in their belief that human emissions impact only the increase since the mid-20th century. Why does the IPCC believe that a virtually identical increase in temperature after 1950 is caused mainly by human influence, when it has no explanation for the nearly identical increase from 1910- 1940?
It is important to recognize, in the face of dire predictions about a 2°C rise in global average temperature, that humans are a tropical species. We evolved at the equator in a climate where freezing weather did not exist. The only reasons we can survive these cold climates are fire, clothing, and housing. It could be said that frost and ice are the enemies of life, except for those relatively few species that have evolved to adapt to freezing temperatures during this Pleistocene Ice Age. It is extremely likely that a warmer temperature than todays would be far better than a cooler one.
I realize that my comments are contrary to much of the speculation about our climate that is bandied about today. However, I am confident that history will bear me out, both in terms of the futility of relying on computer models to predict the future, and the fact that warmer temperatures are better than colder temperatures for most species.
If we wish to preserve natural biodiversity, wildlife, and human well being, we should simultaneously plan for both warming and cooling, recognizing that cooling would be the most damaging of the two trends. We do not know whether the present pause in temperature will remain for some time, or whether it will go up or down at some time in the near future. What we do know with extreme certainty is that the climate is always changing, between pauses, and that we are not capable, with our limited knowledge, of predicting which way it will go next.
Thank you for the opportunity to present my views on this important subject.
Attached please find the chapter on climate change from my book, Confessions of a Greenpeace Dropout: The Making of a Sensible Environmentalist. I would request it be made part of the record.
What does it say about an organization whose butt was kicked ... by France.
BTT. Burn the heretic!

Ah, yes. The “Rainbow Submarine.”
It takes a PhD to figure this out?
-10 this AM in Minneapolis and it’s dang near MARCH!!!
I was hoping he would explain how the CO2 emmision 500 million years ago could be known. - Tom
Pat Moore is a real NWO kind of guy.

-10 in Minneapolis?
We are having a heat wave here in blaisdell Nd....4 above
“Then an Ice Age occurred 450 million years ago when CO2 was 10 times higher than today.”
Wow! I just learned something new today!
Great article ping
Great article.

By analysis of gases in inclusions of minerals when formed.
Would ice core samples also yield such information?
Having seen that reference, I ordered the kindle edition from Amazon and, after skimming the first few chapters I couldn't stop laughing.
The IPCC and the clowns they deem experts, who produce the trash are an endless source of laughter and outright guffaws!
To call themselves "scientists" is a bigger fraud than the entire "Global Warming/Climate Change" invention by political and science incompetents!
Is it possible for "Science" to have a Keystone Kops subculture?
As an example, claiming that the data on which draconian negative changes are proposed for the entire world are "proprietary," and not subject to review and checking should set off loud and clear alarm bells for anyone with an IQ over 70!
Thanks
When scientists speak to the general public it would help for them to say things like "Analysis of gases in inclusions of minerals when formed indicate there was 10 times as much CO2 in the atmosphere 500 million year ago than there is now." -Tom
