I agree. We've been engineering the atmosphere for hundreds of years by burning fossil fuels. We have to continue engineering it by blocking heat energy or radiating it away from the planet somehow. We'll still have to then sequester the carbon we'll continue to emit in various niche industries, and sequester the massive amount of historical emissions.

I was thinking with the cheapened cost of space flight in the next couple of decades, couldn't we lift a huge solar reflector sail in between our planet's poles and the sun? Just block 1% of the heat energy or so, would that be possible?
