IMO we're doing it all wrong. We should be pumping more crap into the atmosphere to reduce the amount of harmful sunlight getting through
Global warming reared it's head after we decided that smog and industrial pollution was bad for us
What we need is another Krakatoa . . .
In the year following the 1883 Krakatoa eruption, average Northern Hemisphere summer temperatures fell by as much as 1.2 °C (2.2 °F).[12] Weather patterns continued to be chaotic for years, and temperatures did not return to normal until 1888.
