Unprecedented droughts, fires and floods are not the “new normal”: Climate change gets nonlinearly worse from here on out. Like an avalanche, the physics of warming determines that a little more warming doesn’t create a little more extremeness, but a lot more. Until we reduce greenhouse gas warming, it gets a lot worse every year. Reducing emissions alone does not reverse warming until after 2300. To reduce warming, we must eliminate all greenhouse gas emissions by 2050, plus remove near 1,000 gigatons of already emitted greenhouse gases from the atmosphere, according to the new 1.5°C report from the Intergovernmental Panel on Climate change.

Meanwhile, a third unprecedented wildfire in California has happened in the last 12 months. At the time of writing, nearly 12,000 structures and 71 lives have been lost in Paradise, California, to the “Camp Fire” that began November 8.
