Yeah. Screw this 'climate change' nonsense. Let's see if we can vaporize the mantle by 2100. The second law exists and climate change is just the first of many

The second law exists and climate change is just the first of many symptoms of running face first into it.
2kW is a sensible limit for living on a planet and having it still be a planet worth living on. You might push it up an order of magnitude or two without cooking humans by fully transforming most habitable land and carefully rejecting 30% of the sunlight whilst using the rest, but that would destroy most ecosystems.
If you want a barren rock to bake, go live on the moon.
- hoseja 4y agoJust to check, have you ever looked up the total solar irradiation wattage? You might be surprised. Climate change isn't "Grug burn too many fire, fire make hot.", it's a comparatively tiny shift in a delicate balance.
- Schroedingersat 4y agoYes. Sunlight that makes it to the surface is about 170PW. Primary energy is about 17TW this is roughly on the order of what can be utilized without drastically altering the planet. GHG emissions shift the balance by about 200TW which is enough to be extremely harmful. 20kW is 170TW which is enough to be similarly harmful (although not to escalate to being apocalyptic). 2000MW per person is enough to raise the temperature of the entire earth (the whole thing, not the surface) by 25 degrees a year.
