Gernot Wagner: Holy wow, +3.5 ppm CO₂ last year, up from +2.4 ppm average the past decade, and +0.6 ppm in the 1960s. It gets scarier the closer you look at it. All this is a stress test for the planet, and it's buckling. Two big reasons for the massive increase: wildfires, and the ocean sinks are shutting down.
