Former NASA Scientist Dispels Notion Global Warming Is ‘Settled’ Science

Former NASA Scientist Dispels Notion Global Warming Is ‘Settled’ Science

A former NASA climate scientist has put out a new report criticizing the argument that global warming is settled science.

“It should be clear that the science of global warming is far from settled,” said Dr. Roy Spencer, a former NASA scientist who now co-runs a major satellite temperature dataset at the University of Alabama-Huntsville.

“Uncertainties in the adjustments to our global temperature datasets, the small amount of warming those datasets have measured compared to what climate models expect, and uncertainties over the possible role of Mother Nature in recent warming, all combine to make climate change beliefs as much faith-based as science-based,” Spencer wrote in a report published by the conservative Texas Public Policy Foundation.

“Until climate science is funded independent of desired energy policy outcomes, we can continue to expect climate research results to be heavily biased in the direction of catastrophic outcomes,” Spencer wrote.

Spencer’s report covers a wide swath of climate science topics from the factors behind global warming, to how scientists make adjustments to climate data, to the “97 percent” consensus figure often cited by politicians and environmentalists.

“Besides, if global warming is settled science, like gravity or the Earth not being flat, why isn’t the agreement 100 percent?” Spencer asked. “And since when is science settled by a survey or a poll? The hallmark of a good scientific theory is its ability to make good predictions.”

“From what we’ve seen, global warming theory is definitely lacking in this regard,” Spencer wrote.

Spencer also explained why climate models tend to over-predict how much warming will occur as greenhouse gas emissions rise. Spencer argues a warming bias is built into the models themselves.

“Since climate models can be ‘tuned’ to produce a rather arbitrary amount of warming, they were tuned to be ‘sensitive’ enough so increasing carbon dioxide alone was sufficient to cause the observed warming,” he wrote.

“It was assumed that there was no natural component of the warming, since we really don’t know the causes of natural climate variations,” he wrote. “As a result, none of the models were prepared for the global warming “hiatus” we have experienced since about 1997, because their climate sensitivity was set too high. The models continued to warm after 2000, while the real climate system essentially stopped warming.”

Indeed, Spencer’s satellite data, which measures the average temperature of the lowest few miles of the atmosphere, showed no significant global warming trend for more than 21 years before an incredibly powerful El Nino warming event hit late last year.

El Nino is a naturally occurring warming of the tropical Pacific Ocean and tends to warm the planet. Satellite temperatures are extremely sensitive to El Ninos (and La Nina cooling events), so mid-tropospheric readings spiked in early 2016.

But temperatures have come down after El Nino faded, and now it looks like a La Nina is setting in. Some even expect the so-called “hiatus” in global warming to return after this year’s La Nina ends.

Top Scientist Resigns Admitting Global Warming Is A Big Scam

Top Scientist Resigns Admitting Global Warming Is A Big Scam

Share on Tumblr

Top US scientist Hal Lewis resigned from his post at the University of California after admitting that global warming was a big scam, in a shocking resignation letter.

From the Telegraph

The following is a letter to the American Physical Society released to the public by Professor Emeritus of physics Hal Lewis of the University of California at Santa Barbara

Sent: Friday, 08 October 2010 17:19 Hal Lewis
From: Hal Lewis, University of California, Santa Barbara
To: Curtis G. Callan, Jr., Princeton University, President of the American Physical Society
6 October 2010

Dear Curt:

When I first joined the American Physical Society sixty-seven years ago it was much smaller, much gentler, and as yet uncorrupted by the money flood (a threat against which Dwight Eisenhower warned a half-century ago).

Indeed, the choice of physics as a profession was then a guarantor of a life of poverty and abstinence – it was World War II that changed all that. The prospect of worldly gain drove few physicists. As recently as thirty-five years ago, when I chaired the first APS study of a contentious social/scientific issue, The Reactor Safety Study, though there were zealots aplenty on the outside there was no hint of inordinate pressure on us as physicists. We were therefore able to produce what I believe was and is an honest appraisal of the situation at that time. We were further enabled by the presence of an oversight committee consisting of Pief Panofsky, Vicki Weisskopf, and Hans Bethe, all towering physicists beyond reproach. I was proud of what we did in a charged atmosphere. In the end the oversight committee, in its report to the APS President, noted the complete independence in which we did the job, and predicted that the report would be attacked from both sides. What greater tribute could there be?

How different it is now. The giants no longer walk the earth, and the money flood has become the raison d’ĂȘtre of much physics research, the vital sustenance of much more, and it provides the support for untold numbers of professional jobs. For reasons that will soon become clear my former pride at being an APS Fellow all these years has been turned into shame, and I am forced, with no pleasure at all, to offer you my resignation from the Society.

It is of course, the global warming scam, with the (literally) trillions of dollars driving it, that has corrupted so many scientists, and has carried APS before it like a rogue wave. It is the greatest and most successful pseudoscientific fraud I have seen in my long life as a physicist. Anyone who has the faintest doubt that this is so should force himself to read the ClimateGate documents, which lay it bare. (Montford’s book organizes the facts very well.) I don’t believe that any real physicist, nay scientist, can read that stuff without revulsion. I would almost make that revulsion a definition of the word scientist.

So what has the APS, as an organization, done in the face of this challenge? It has accepted the corruption as the norm, and gone along with it…

I do feel the need to add one note, and this is conjecture, since it is always risky to discuss other people’s motives. This scheming at APS HQ is so bizarre that there cannot be a simple explanation for it. Some have held that the physicists of today are not as smart as they used to be, but I don’t think that is an issue. I think it is the money, exactly what Eisenhower warned about a half-century ago. There are indeed trillions of dollars involved, to say nothing of the fame and glory (and frequent trips to exotic islands) that go with being a member of the club.

UN Official: The Real Reason For The Global Warming Scare Is To Kill Off Capitalism

UN Official: The Real Reason For The Global Warming Scare Is To Kill Off Capitalism | Truth And Action

This confession is either quite arrogant in the fact that she feels she can admit such a thing without consequence, or the U.N. is backpedaling as the world wakes up to this massive fraud our leaders have perpetrated on us all.

Economic Systems: The alarmists keep telling us their concern about global warming is all about man’s stewardship of the environment. But we know that’s not true. A United Nations official has now confirmed this.

At a news conference last week in Brussels, Christiana Figueres, executive secretary of U.N.’s Framework Convention on Climate Change, admitted that the goal of environmental activists is not to save the world from ecological calamity but to destroy capitalism.

“This is the first time in the history of mankind that we are setting ourselves the task of intentionally, within a defined period of time, to change the economic development model that has been reigning for at least 150 years, since the Industrial Revolution,” she said.

Referring to a new international treaty environmentalists hope will be adopted at the Paris climate change conference later this year, she added: “This is probably the most difficult task we have ever given ourselves, which is to intentionally transform the economic development model for the first time in human history.”

The only economic model in the last 150 years that has ever worked at all is capitalism. The evidence is prima facie: From a feudal order that lasted a thousand years, produced zero growth and kept workdays long and lifespans short, the countries that have embraced free-market capitalism have enjoyed a system in which output has increased 70-fold, work days have been halved and lifespans doubled.

Figueres is perhaps the perfect person for the job of transforming “the economic development model” because she’s really never seen it work. “If you look at Ms. Figueres’ Wikipedia page,” notes Cato economist Dan Mitchell: Making the world look at their right hand while they choke developed economies with their left.
