Exceeding Global Warming Limit

The generally accepted conservative limit to global warming that avoids widespread environmental disaster is 2C. It now looks like we are 95% likely to exceed that limit by the end of the century. As mentioned previously, the stated numbers are typically the conservative ones to minimize controversy. The range of expected values is between 2C and 4.9C.

The limit that would save many Pacific Islands is 1.5C.

Now that we’ve learned more and have acquired sufficient data, the result shifts the conversation for concerned people from “Can we stop it?” to “How we will adapt?”
