RE "constant amount of sunlight", this is actually untrue. The suns energy output is increasing roughly 10% per billion years. So it's actually never been stronger. It also means that we have much less habitable time on earth than we thought
- zaik 4y ago> 10% per billion years So it's about 0.000029% more since humans have evolved?

- function_seven 4y agoAn annual sunlight increase of 0.00000001 % is close enough to "constant" to make no difference. And I didn't even bother with compounding, so the real number is even smaller. It's dwarfed by other solar cycles, and those are dwarfed by the near-doubling of CO2 in our atmosphere. I'm not automatically against geo-engineering approaches, but we do need to consider them desperate moves compared to the reduction of the GHGs
