Nothing will change until developed rich countries are starting to hurt. And I don't think it's going to hurt enough in 10 or 20 years. The pain will come slowly, people won't see it. It's like going back to the middle age so slowly, that the population don't realize or feel it. And honestly, wars and trump are making climate concerns so difficult to think about.

I initially supported this comment but no, I think it's worse than this. As rich countries cut back, dirty energy becomes cheaper and developing nations just use more. They'll need to use more just to fight the climate. India, for instance, is going to need a whole lot of air conditioning just to survive.

Sure, blame developed nations for getting us here, but the path forward isn't solely in the hands of those developed nations.

The initial pain will be diffuse and not obviously caused by global warming. For example, destabilization of equatorial countries due to wet bulb temperatures, through multiple causal paths: worse education outcomes (many days off school during hot months), worse economy (can't work outside), worse life satisfaction -> more autocracies, more water scarcity. Then you get more emigration to the colder north, more confl…

Wasn't a drought originally part of the cause of Syria's collapse into civil war? Climate change is already causing unrest in equitorial countries, mass migration and a corresponding rise in authoritarianism / right wing populism in Europe.

You're making the "It's snowing there can't be global warming" argument in reverse.

One local drought can't be attributed to or be proof of global warming.

It's like smoking causing lung cancer; (the following numbers are made up) 5 in 100 non-smokers might get lung cancer but 20 in 100 smokers do. 5 of those smokers would have gotten lung cancer anyway and 15 wouldn't have but there's no way to know which individuals are in which cohort.

The main driver of this is human-produced CO2, and there are meaningful ways to reduce usage. -Switch to an electric vehicle -Migrate from gas appliances (range, furnace, water heater) to electric (induction, heat pumps) -If your power grid isn’t clean, add rooftop or balcony solar -Encourage friends and family to do the same

And don't fly

And eat vegan and regional produce

And don't build things out of concrete

And better get a few room mates

FWIW my personal assessment is that this acceleration is both real and largely out of our control. Models in the past did not attempt to account for non-anthropogenic carbon emissions, but as we experience further warming, most especially in the Arctic, feedback loops and tipping points mean that this (carbon emissions caused by “natural” processes) are becoming more evident. This is especially sensitive because a la…

> Oh and roughly 65M of sea level rise as the planet shifts to a snow/ice-free mode.

Where is this new figure coming from? It seems about 60X what's being published elsewhere.

I don't see the US doing anything about global warming regardless of who's in charge. China has won on manufacturing cheap wind/solar energy and is scaling up their cheap EV manufacturing right now. Trump is definitely accelerating China's future dominance by completely forgoing anything related to developing or manufacturing green tech in favor of fossil fuels, but I think both parties would rather get into a confli…

At this point, one possible 50-years projection of outcomes here is that China eventually declares the US an existential threat to humanity's continued existence and deploys economic or military power to stop it unless the US gets its act together on carbon emissions. Can't build those AI datacenters if China has physically embargoed the chips. That may seem extreme, but the Chinese culture is more collectivist than…

Albedo modification (stratospheric aerosols) seems much cheaper than direct air capture, as a stopgap.

China creates about 30–35% of global emissions. India about 8% but it is climbing fast. What rich countries do is they just export their factories to other countries and say: look we do not pollute.

US is the largest historical emitter… responsible for something like 25% of all man made CO2 emissions

The entire west world contributes 28.8%. US is about 11%. [1]

Relying on DAC is putting our fate in the hands of a technology we've never deployed beyond some pitifully small pilot projects, and expecting that we're going to be able to deploy that at a larger scale than we've deployed any technology since electricity itself.

We're going to have to resort to geoengineering alright, but it's gonna likely be stratospheric sulfate injection given how cheaply that can be done. Is it ideal? Nope. Better than global warming itself? Time will tell.
