Projected temperatures well above targets agreed to at last year’s historic Paris climate talks
The world’s current game plan to combat climate change will miss the mark. Crunching the numbers on 187 nations’ climate action proposals announced in advance of the December 2015 Paris Agreement, researchers estimate that the efforts will limit global warming to 2.6 to 3.1 degrees Celsius above preindustrial levels. That’s far above the goal agreed upon in Paris of limiting warming to well below 2 degrees by 2100 (SN: 1/9/16, p. 6).
The 2-degree goal is not out of reach yet, though. More ambitious climate action — such as greater emissions reductions and removing carbon from the atmosphere – could keep warming in check, the researchers report June 29 in Nature.
Society doesn’t have much leeway when it comes to combatting climate change, notes the research team
