Celsius by 2100: a first scenario does
so with a probability of about 50 percent, and a second scenario with a «likely»
chance (better than 66 percent).»
Peters is a researcher who is on the record stating that he thinks there's little
chance of holding warming to 2 degrees
Celsius unless we come up with
so - called «negative emissions» technologies that allow us to actively withdraw carbon dioxide from the atmosphere later in the century.
