There’s still time to fix climate — about 11 years: Scientific American
28 Oct 2021
ON October 31 world leaders will descend on Glasgow, Scotland, for the United Nations Climate Change Conference, or COP26, in a last-ditch effort to defuse the climate emergency by limiting global warming to less than 1.5 degrees Celsius.
