Yesterday President Trump announced he is exiting the United States from the climate deal that the Obama administration pulled together against all odds with 190 nations from around the world. Trump justified the abrogation of the deal for several reasons, and cited an MIT study:
Even if the Paris Agreement were implemented in full, with total compliance from all nations, it is estimated it would only produce a two-tenths of one degree — think of that; this much — Celsius reduction in global temperature by the year 2100. Tiny, tiny amount.
But of course the study doesn’t stay that.
