The Paris climate agreement, which is intended to limit the severity of climate change, will likely be a substantial benefit to most of the world's economies, argue researchers in a study published in the journal Nature. Not placing limits on climate-warming carbon emissions, however, would be costly for nearly everyone. The world's three largest economies — the U.S., Japan, and China — are all expected to benefit from meeting the 1.5 Celsius carbon target, although the researchers found the poorest nations in the world, which are generally also the hottest, serve to benefit the most. Rhodium Group's Kate Larsen, a member of the Impact Lab, explains that even if nations don't meet the 1.5 Celsius target, the benefits of mitigating climate change can still be momentous.
