What is the danger we're trying to avoid, though? We don't talk about this enough. It may cost 100 trillion to reduce temperature in 2100 by 0.1F .... Likely we'll slowly wean off usage as fusion/nuclear become more popular and we have a battery breakthrough or two. We have very little to fear from climate change, as far as I can tell. We need to rapidly advance, as there are far greater dangers. Before you say blah blah catastrophic thing is going to happen: think about the last 20k years. There have probably been quite a few extremely crazy events that are much more devastating than 1 degree in average temperature change. (i.e. 12k years ago we had 100ft sea level rise ... uhh)

We are looking at 3 degrees right now. The previous ice age was ~4 degrees colder than pre-industrial levels. So 3 degrees sounds pretty much in that context.

    Seems my information is out of date. https://news.ucar.edu/132755/scientists-nail-down-average-temperature-last-ice-age https://news.ucar.edu/132755/scientists-nail-down-average-te... claims it's more like 5 degrees compared to pre-industrial levels (6 compared to now). Still though. If 5 degrees is the difference between the early 1800s and an ice age, that we've already done ~1 degree seems enormously alarming.

      That's what I thought. I've seen 10 degrees as well. Sorry man huge hard disagree. 100 trillion to maybe reduce temperature by a tiny tiny amount is clearly not worth it. "But but but, something might happen!" There's plenty already happening. Increase supply of healthcare, for example ...

        You're confused. We shouldn't spending "100 trillion to maybe reduce temperature by a tiny tiny amount". We should spend that to not raise the temperate indefinitely. Clearly we can't just raise the temperate 50 degrees. Everyone dies then. But the no-climate-action idea will in fact end up there. It will just take centuries. So we have to put a line in the sand at some point. We literally can't go on pumping CO2 into the atmosphere and de-terraform Earth. We know roughly what is safe, and we're shooting way past it.

        > indefinitely ...? Yea. If we keep burning fossil fuels. I mean, they will run out, but it's not going to happen in a long time. Long enough for us to change the climate way past human survivability on most of Earth. > we're not in any danger from our climate What? Of course we are. That's the entire point. You lower the average temperature 6 (5 from pre-industrial levels) degrees and you've got an ice age. Half of Europe literally covered in several kilometers of ice! We've already raised the temperature 1 degree above baseline. That's a LOT.

That's a LOT. we're coming out of an ice age
