Flirting with the 1.5°C Threshold

Global leaders are meeting in New York this week to sign the Paris climate agreement. One of the expressed purposes of the document is to limit warming to “well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C.” A Climate Central analysis shows that the world will have to dramatically accelerate… Read More
