Climate policies saved the world from catastrophic warming, say leading climate scientists. On September 1, a consortium that produces analyses for the UN Intergovernmental Panel on Climate Change (IPCC) released new scenarios. They say the new worst-case scenario is just 3.3 degrees Celsius of warming by 2100 over pre-industrial temperatures. That’s down from 4.6 to 4.9 degrees of the last three generations of climate scenarios used by the IPCC. “Our business-as-usual projection of 3C of war...

“And then the expected happened,” Ausubel said about the IPCC. “Opportunists flowed in. By 1992, I stopped wanting to go to climate meetings." https://t.co/XCIsULFRv9

"The 8.5 scenario originated in the year 2000. But the Business-As-Usual scenario in the first IPCC report in 1990 was equally extreme. As a reviewer of the first IPCC report, Jesse [Ausubel] critiqued the BAU scenario as “Brezhnevite” but his review was totally ignored." From his review: "In a peculiar choice of words, the Intergovernmental Panel on Climate Change in 1990 designated as 'Business-as-Usual' its scenario which stifled and even reversed the 130-year trend. 'Business as Usual' wa...

Already by the 1970s, top energy analysts knew abundant natural gas would displace coal, resulting in lower emissions. And so Malthusian scientists, in order to create their outlandishly apocalyptic scenarios, demonized them as climate deniers and drove them out of the IPCC. https://t.co/5hvDvYNf0U https://t.co/eW00eKLW2O [Quoted] Climate policy prevented the IPCC’s high emissions scenario, say the media. It didn’t. The scenario was never possible as it predicted burning 5x more coal than is...

Governments, banks, and corporations across the developed world have for nearly four decades treated the United Nations Intergovernmental Panel on Climate Change (IPCC) as the final word on the science of climate change. The Obama and Biden administrations regulated carbon dioxide as a pollutant on the strength of IPCC findings. The European Union built its emissions trading system around IPCC scenarios. The United Kingdom anchored its 2008 Climate Change Act in projections drawn from the pan...

Climate policy prevented the IPCC’s high emissions scenario, say the media. It didn’t. The scenario was never possible as it predicted burning 5x more coal than is known to exist, even as natural gas was replacing it. The IPCC must be radically reformed or shut down. https://t.co/vIbVRNnNyF

After years of apocalyptic climate alarmism, …. ‘The worst-case scenarios that guide the work of climate scientists and feed into the major reports of the Intergovernmental Panel on Climate Change have been dramatically, quietly and officially revised down’: https://t.co/KazxIWq624
