Climate change odds much worse than thought. New analysis shows warming could be double previous estimates.

Without rapid and massive action, the problem will be about twice as severe as previously estimated six years ago – and could be even worse than that.” (emphasis added).

Compared to other climate modeling studies, the MIT study is unique. “[T]he MIT model is the only [model] that interactively includes detailed treatment of possible changes in human activities as well – such as the degree of economic growth, with its associated energy use, in different countries.” 

The Study concluded that warming projections are more severe than we thought, “indicat[ing] a median probability of surface warming of 5.2 degrees Celsius by 2100, with a 90 percent probability range of 3.5 to 7.4 degrees.”
