A couple of important videos

The first is an interview with Guy McPherson, who writes Nature Bats Last blog. In it he mentions ‘global dimming’. I’d seen it referred to but wasn’t really up to speed on it. It’s what happens when particulates from the burning of fossil fuels (which is actually pollution) collect in the atmosphere and reflect incoming sunlight back into space, providing a cooling effect to oppose the heating effect from CO2 in the atmosphere, also caused by the burning of fossil fuels. It’s a catch 22 situation—one cools, one heats. If we stop burning fossil fuels we lose the dimming/cooling effect and the earth cops the full brunt of the warming caused by CO2. If we continue burning fossil fuels, we add more CO2 and we get more warming.

Here’s Guy :
