Half a Degree could Make a World of Difference
Observational records show us that half a degree of warming in the recent past has brought significant increases in extreme weather events, which provides another line of evidence for what an additional 0.5C of warming could entail. Differentiating climate impacts between 1.5C and 2C warming above pre-industrial levels has been a hot topic in climate science since the adoption of the 1.5C long-term temperature limit in the Paris Agreement and much research is underway for inclusion in the IPCC special report on impacts at 1.5C warming.
