Is it too late to reverse climate change?
No, it is not too late to reverse the trajectory of climate change or limit its worst impacts, though some changes are already irreversible on human timescales, and the window for effective action is rapidly closing. The scientific consensus (from IPCC, NASA, UNEP, and others) is clear: human-caused greenhouse gas emissions are driving warming, and deep, rapid cuts can still stabilize and eventually reduce temperatures, while every fraction of a degree of avoided warming reduces risks.
