It’s getting hot out there. For a stretch of 16 months running through August 2016, new global temperature records were set every month.[1] Ice cover in the Arctic sea hit a new low this past summer, at 525,000 square miles less than normal.[2] And apparently we’re not doing much to stop it: according to Professor Kevin Anderson, one of Britain’s leading climate scientists, we’ve already blown our chances of keeping global warming below the “safe” threshold of 1.5 degrees.[3]
If we want to stay below the upper ceiling of 2 degrees, though, we still have a shot. But it’s going to take a monumental effort. Anderson and his colleagues estimate that in order to keep within this threshold, we need to start reducing emissions by a sobering 8-10% per year, from now until we reach “net zero” in 2050.[4] If that doesn’t sound difficult enough, here’s the clincher: efficiency improvements and clean energy technologies will only win us reductions of about 4% per year at most.
