The rare spots of good news on climate change
The deadly consequences of climate change only grew clearer this year, as record-shattering heat waves, floods, and wildfires killed thousands and strained the limits of our disaster responders.
But amid these stark signs, there were also indications that momentum is beginning to build behind climate action. Indeed, there’s good reason now to believe that the world could at least sidestep the worst dangers of global warming.
So what are the signs of progress amid the climate gloom?
The grimmest scenarios that many fretted about just a few years ago look increasingly unlikely. That includes the 4 or 5 °C of warming this century that I and others previously highlighted as a possibility.
The UN climate panel’s earlier high-end emissions scenario, known as RCP 8.5, had found that global temperatures could rise more than 5 °C by 2100. Those assumptions have been frequently included in studies assessing the risks of climate change, delivering the eye-catching top-end results often cited in the press.
