And how, exactly have we been 'accidentally' cooling the planet?
Tiny particles from the combustion of coal, oil and gas can reflect sunlight and spur the formation of clouds, shading the planet from the sun’s rays. Since the 1980s, those particles have offset between 40 and 80 percent of the warming caused by greenhouse gases.
OK, then here's an idea: How about we NOT STOP BURNING COAL, OIL, AND GAS?
Isn’t it Gates who has been working at shading earth?
