You need to be albedomaxxing.

You need to be spending all your time blotting out the sun for the greater good. You need to be casting the largest possible shadow. You need to reflect so much light back into space that a new Ice Age begins. You need to shine so brightly you slice holes in clouds.

You need to transform into billions of white swifts and take to the skies. You need to be reflecting so sharply that Earth quadruples in luminous intensity. You need to make Earthshine a viable source of photovoltaic power on the moon.
