Many prominent scientists no longer agree with the predictions espoused by the highly politicized “science” of man-made global warming.
Here are a few cases of interest…
We are doomed, say climate change scientists associated with the United Nations Intergovernmental Panel on Climate Change, the United Nations body that is organizing most of the climate change research occurring in the world today. Carbon dioxide from man-made sources rises to the atmosphere and then stays there for 50, 100, or even 200 years. This unprecedented buildup of CO2 then traps heat that would otherwise escape our atmosphere, threatening us all.
“This is nonsense,” says Tom V. Segalstad, head of the Geological Museum at the University of Oslo and formerly an expert reviewer with the same IPCC. He laments the paucity of geologic knowledge among IPCC scientists — a knowledge that is central to understanding climate change, in his view, since geologic processes ultimately determine the level of atmospheric CO2.
“The IPCC needs a lesson in geology to avoid making fundamental mistakes,” he says. “Most leading geologists, throughout the world, know that the IPCC’s view of Earth processes are implausible if not impossible.”
Defectors from IPCC Report Speak
A United Nations climate change conference in Poland got a surprise from 650 leading scientists who scoff at doomsday reports of man-made global warming – labeling them variously a lie, a hoax and part of a new religion.
Their voices will also be heard in a U.S. Senate minority report quoting the scientists, many of whom are current and former members of the U.N.’s own Intergovernmental Panel on Climate Change.
About 250 of the scientists quoted in the report have joined the dissenting scientists in the last year alone.
In fact, the total number of scientists represented in the report is 12 times the number of U.N. scientists who authored the official IPCC 2007 report.
Here are some choice excerpts from the report:
* “I am a skeptic … . Global warming has become a new religion.” — Nobel Prize Winner for Physics, Ivar Giaever.
* “Since I am no longer affiliated with any organization nor receiving any funding, I can speak quite frankly … . As a scientist I remain skeptical.” — Atmospheric Scientist Dr. Joanne Simpson, the first woman in the world to receive a Ph.D. in meteorology and formerly of NASA who has authored more than 190 studies and has been called “among the most pre-eminent scientists of the last 100 years.”
UN Blowback: More Than 650 International Scientists Dissent Over Man-Made Global Warming Claims
Richard Tol, a professor of economics at the University of Sussex in the United Kingdom and an expert on climate change, removed his name from the latest Intergovernmental Panel on Climate Change (IPCC) report. While he considers much of the science sound and supports the underlying purpose of the IPCC, Tol says the United Nations agency’s inflammatory and alarmist claims delegitimize the IPCC as a credible and neutral institution.
“In the SPM [Summary for Policymakers], and much more largely in the media, we see all these scare stories,” Tol tells National Review Online. “We’re all going to die, the four horsemen of the apocalypse . . . I felt uncomfortable with the direction [the IPCC report] was going.”
Tol, who has been working with the IPCC since 1994, was the lead author of Chapter 10 of the report, on key economic sectors and services. He was also a contributor to Chapters 17 and 19, on the economics of adaptation to climate change and emergent risks, respectively.
He took his name off of the final summary because he felt the IPCC did not properly account for human technological ingenuity and downplayed the potential benefits of global warming.
One of the world’s most eminent climate scientists – for several decades a warmist – has defected to the climate sceptic camp.
Lennart Bengtsson – a Swedish climatologist, meteorologist, former director of the Max Planck Institute for Meteorology in Hamburg and winner, in 2006, of the 51st IMO Prize of the World Meteorological Organization for his pioneering work in numerical weather prediction – is by some margin the most distinguished scientist to change sides.
“He’s a big, big player. The biggest by far to change sides,” says the GWPF’s Benny Peiser. “What’s particularly significant is that his speciality is climate modelling – and computer models, as you know, are at the heart of global warming theory. He is the most significant figure to admit, as many modellers are beginning to notice, that there is an increasing discrepancy between what the models predicted and what the real world data is actually telling us.
Lennart’s is just the latest in a series of defections from the climate alarmist camp to the cause of realism.
James Lovelock; English scientist; inventor of Gaia Theory; godfather of Green.
Formerly an arch-exponent of man-made climate doom theory, predicting as recently as 2007, that “billions of us will die; few breeding pairs of people that survive will be in Arctic”. Now admits: “The problem is we don’t know what the climate is doing. We thought we did 20 years ago.” Pro-nuclear; mildly pro-fracking; anti-wind farms.
Judith Curry – American climatologist and chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology.
Though still a self-described “luke warmer”, Curry was probably the most senior member of the warmist establishment – up until Bengtsson’s defection – to fraternise with the enemy. This has earned her the badge of honour of being labelled “anti-science” by Michael Mann. In her blog Climate Etc she tries to encourage climate alarmists to show a sense of proportion and admit the limits of their knowledge. Of the National Climate Assessment report, she wrote:
My main conclusion from reading the report is this: the phrase ‘climate change’ is now officially meaningless. The report effectively implies that there is no climate change other than what is caused by humans, and that extreme weather events are equivalent to climate change.
Fritz Vahrenholt – German professor; environmental activist; one of the founders of the German green movement; former Environmental Senator of Hamburg.
Vahrenholt’s climate-sceptical bestseller Die Kalte Sonne (translated as The Neglected Sun) sent shock waves through the German green movement. It earned him the title “eco-reactionary” from the left-liberal German media which was appalled at what they saw as his betrayal of the Cause. Vahrenholt argued that the sun – not CO2 – was the most significant driver of climate change; that predictions of man-made climate doom had been overdone; and that science had been corrupted by political indoctrination.
Sigmar Gabriel – German vice-chancellor; ex environment minister; formerly an enthusiast for green energy policy; now admits that Germany’s Energiewende – its transition to renewables – has been pointless and destructive.
George Monbiot – humorist; Guardian scribe; environmental campaigner; scourge of climate sceptics; has since divided the green movement over his removal of the Atomkraft? Nein Danke sticker on the back of his florally-decorated VW Kombi and his decision that nuclear energy is, after all, the way forward. For this crime he is now being harried by green campaigners who are offering a £100 reward to anyone prepared to arrest him for his “crimes against the environment and humanity.”
Highly trained scientists changed their mind. They no longer believe the CO2 causes the earth to warm. How can you be so sure it does? They changed their mind. So can you.
