Committee on Science, Space, and Technology Chairman Lamar Smith: 'The President and others often claim that 97 percent of scientists believe that global warming is primarily driven by human activity. However, the study they cite has been debunked. When asked today whether the science of climate change is settled or if uncertainties remain, witnesses unanimously said that the science is not settled. They also discussed concerns with the IPCC process, including lack of transparency in author and study selection, and inconsistent approaches to data quality, peer review, publication cut-off dates, and the cherry-picking of results.'
“Academics who research climate change out of curiosity but find less than alarming things are ignored, unless they rise to prominence in which case they are harassed and smeared,” said Richard Tol. - “Other eminent meteorologists have been treated like Bengtsson was… merely for sticking to the academic literature, as reflected by the IPCC, that there is no statistical evidence that the impact of natural disaster has increased because of climate change,” Tol said.
Tol gained notoriety when reports came out that he removed his name from the IPCC’s fifth climate assessment because it had become too “alarmist”. Since then Tol says he has been attacked by environmentalists and left-leaning media for not agreeing that global warming would bring catastrophe.
“Governments nominate academics to the IPCC – but we should be clear that it is often the environment agencies that do the nominating,” Tol said in his written testimony, adding that it’s “rare that a government agency with a purely scientific agenda takes the lead on IPCC matters.”
“As a result, certain researchers are promoted at the expense of more qualified colleagues,” Tol said. “Other competent people are excluded because their views do not match those of their government. Some authors do not have the right skills or expertise, and are nominated on the strength of their connections only.”
“The United States is by far the IPCC's largest funder - over $43 million since the beginning (over four times more than second-place Germany), and that's just for the basic UN bureaucracy, not including many more millions for technical support, experts, meetings, and translations. But it's true that the U.S. administration makes its wishes known to the IPCC through State Department delegations of political appointees.”
