Either the world accepts that nuclear energy along with wind and solar is part of the solution to climate change, or we will be forced into geoengineering solutions. We may have already reached that point.

There are lots of nuclear reactors being built world wide currently. The problem is that it takes forever to build nuclear reactors and we would need twenty times as much nuclear as we have right now just to replace coal. An additional twenty times as much as we have now to replace oil. And an additional fifteen times as much as we have right now to replace gas. Nuclear is not particularly cheap either.

We’re past the point that nuclear can help. We broke the planet. But hey. “Needs more study.” and academics are living large, unlike the poor billionaires.

This is defeatist and also not true. We adopt nuclear, invest in carbon capture technologies, and employ geoengineering strategies as needed until fusion comes online. This is a solvable technical problem with significant political hurdles.

There is no reason to believe that fusion power will be cheap.

The Earth's greatest temperature was before humans ever existed

What's your point?

“Point” seems generous. Looking at their post history their either a shill or a troll. That said I’ve heard real people in real life with alleged “real ideas” that say that because system warming has happened in the planet’s distant past we should just accept it as Gosh’s Will or whatever and accept whatever divine punishment we deserve or something. It always gets very fuzzy on how we actually continue to have a world with these problems but with religious fanatics I expect that Sky Daddy will come save them personally so they are unconcerned

As with all things I feel like a little from column A, a little from column B

Quip: But when the patient's temp is high enough, everyone in the ER knows that you gotta go straight to the ice-water bath.

How many square miles of solar reflector could each Starship launch carry to a stable-ish region near the Earth-Sun L1 point?

It came broken in the mail?

It broke many times throughout its history. There is just zero evidence that we cannot adjust, mitigate, prevent etc. - otherwise we might as well do nothing because we are all doomed anyway.

I read your comment as meaning that humans are not responsible for climate change. But now I think you meant that humans may be responsible but they can fix it. Well, all I can say is that I hope that they can.

There are people saying we should not just not stop, but even increase sulfur injection: https://en.wikipedia.org/wiki/Stratospheric_aerosol_injectio... The thing is, this is not a one time solution. We would have to do it continuously, or else the temperature would quickly rise again. And we would have to increase sulphur injection if the CO2 level keeps rising. It could be a temporary solution though, e.g. until al…

Yeah I just read this, not really sure what the alternatives are now? Looks like the situation is spiraling out of control so...?? Cover Greenland in a reflective blanket? Sounds like it is time to panic...and actually do what needs to be done.

The time to panic was 1980. We’re well past that point by now, and have already committed to at least a whole degree of warming, if not more.

> Cover Greenland in a reflective blanket?

Ha! I want to see a study on this now. Greenland already has high albedo so it wouldn’t be that effective; it would protect the ice sheet but also be covered by new snow, if any.

Go back to the Hadean era, bro.

Nuclear is dead, it's better to install 10x as much solar and batteries right now. "Carbon capture" is also highly dubious. Direct air capture is the only realistic version and it'll take a significant portion of world GDP (8% to 20%) on an ongoing basis, which we are not spending. I'll keep you posted when that changes. Fusion is not coming online in our lifetimes.

We're not headed for +8C, but we're never going to see +1C or below again in our lifetimes. Maybe in the 2300s they'll have it under control.
