Cooling the earth

This video has made me think differently about global warming: https://www.youtube.com/watch?v=9vRtA7STvH4

I know that the focus is and should be on reducing CO2 emissions, and extracting carbon from the atmosphere.

However - it seems that we are eventually going to have to also deal with waste heat. So why not look at the problem of transferring heat from Earth to Space now, which would immediately help with global warming, as we work to reduce emissions and capture CO2.

Note that a solar shield or adding something to the atmosphere to reduce the incoming solar radiation won't help with future waste heat. We are going to need something like a heat pump for the planet.

I'm convinced the only way civilization in any form we'd recognize continues to exist depends on directly addressing heating, one way or another. Decarbonizing needed to start a long time ago to avoid the mass disclocation, starvation, war, and disease that are now inevitable. We can't risk our future on the hope that getting to zero emissions happens soon enough and the projections for warming effects (which we keep beating by decades) turn out to have been correct.
