I’ve been hoping a volcano would do it for us. I prefer the planet’s natural self-correction system to human attempts to fool with Mother Nature.
And to think, back in the 1970s there was a hare brained scheme to mine coal, grind it to dust, mix it with oil and spray it on the ice fields to increase absorption of heat from the sun to prevent THE COMING ICE AGE!
On 9-11 when the government ordered ALL aircraft grounded the earth temp in the US actually went up a couple of degrees. Maybe what we need is more contrails from jet aircraft!
Depending on your age, you’ll likely get more cooling than you want during the rest of our life.
