The New Yorker coverage of the IPCC special report on 1.5°C, quoting Climate Analytics' Dr Adelle Thomas. “Robust scientific literature now shows that there are significant differences between 1.5 and 2 degrees,” Adelle Thomas, a geographer from the Bahamas and also one of the report’s lead authors, told me. “The scientific consensus is really strong. It’s not just a political slogan: ‘1.5 to stay alive.’ It’s true.”

INCHEON, South Korea — A landmark report from the United Nations’ scientific panel on climate change paints a far more dire picture of the immediate consequences of climate change than previously thought and says that avoiding the damage requires transforming the world economy at a speed and scale that has “no documented historic precedent.” The report “is quite a shock, and quite concerning,” said Bill Hare, an author of previous I.P.C.C. reports and a physicist with Climate Analytics, a nonprofit organization. “We were not aware of this just a few years ago.”
A landmark report released Sunday from the world's top climate change group said "rapid, far-reaching and unprecedented changes in all aspects of society" are required to ward off the worst impacts of global warming. This report shows the longer we wait, "the more difficult, the more expensive and the more dangerous it will be,” said Bill Hare, a physicist with the nonprofit group Climate Analytics.
There is no scenario to keep global warming to 1.5°C (2.7°F) that allows coal to be burned for electricity by the middle of this century, a major United Nations (UN) climate report says. The UN’s Intergovernmental Panel on Climate Change (IPCC) report concludes human-caused greenhouse gas emissions have already pushed global average temperatures up by 1°C since the second half of the 19th century. Dr. Bill Hare, CEO of Climate Analytics, took part in the IPCC meeting as a science advisor to Small Island Developing States and was accredited to the Grenada delegation. He said the report “has sent the strongest message yet from the scientific community that the era of fossil fuels has to end soon if we are to protect the world from dangerous climate change and limit warming to 1.5°C.”
The Earth has already warmed 1 degree Celsius (1.8 degrees Fahrenheit) since the 19th century. Now, a major new United Nations report has looked at the consequences of jumping to 1.5 or 2 degrees Celsius. “If you’re looking at this one region, which is already water-scarce today and sees a lot of political instability, half a degree makes a really big difference,” said Carl-Friedrich Schleussner, the head of climate science and impacts at Climate Analytics. “It’s a good reminder that no one experiences the global average temperature.”
