It makes me happy that it's possible that future humans might live again on an earth 12,000 years in the future which has cooled again after our civilisation has boiled the planet.
- usrusr 3y agoWhy would it cool in 12k years? We are loading the atmosphere with carbon sequestered over much longer periods. Some of which even happened in a phase of massive imbalance in the evolutionary "war" between plants and plant consumers: trees had found a way to never rot (be consumed) which is rather tragic for incumbent biological systems but a crazy boost for carbon sequestering. The problem is not that we produce heat, the problem is that we change the balance point between energy influx from the sun and energy emission to space. That changed balance point will remain changed much, much longer than 12k years. If we don't have a technological miracle, humans 12k in the future will live in tiny habitable zones near the poles.
