Even the crotchetiest and most out-of-touch people I know basically accept that the Earth is warming now. They just either disagree on the cause or proportion. Some people just naturally resist hyperbole or sensationalist rhetoric, and I find it very helpful to reframe the argument from doom and gloom and fire and brimstone to something more realistic and grounded: "The longer we put off doing something, the harder a…

The problem with Pascal's wager logic is you have to change your behavior based on all kinds of crazy low-probability events. You must worship every god, be an AI-doomer, a climate-doomer, a nuclear-doomer. Pascal's wager is generally agreed to be logically unsound, so it's somewhat insane that we've revived it in all these modern contexts. If you believe in it, at least be consistent and sacrifice a goat to Zeus eve…

Here’s a video called “Is AI safety a Pascal’s Mugging?”: https://youtu.be/JRuNA2eK7w0

I haven’t watched it back but from what I remember the main point of the video is that kind of situation happens when the probability involved is vanishingly small, and all the events you listed don’t have a vanishingly small probability, so they are not Pascal’s wager situations, just a normal rational safety concerns with particularly high consequences

Presuming that you yourself have "graduated" (what from is unclear), it's particularly audacious that you make this claim because it shows rather cleanly how poor a marker of quality an education is. The answer has never laid in ever more elaborate designs to disenfranchise particular members of the population. It's always been in building community. A community is what helps stabilize, helps tighten up distributions…

The parent comment said high school which is compulsory, free, and a very low bar. Our nation and world is largely being wrecked by the malicious on behalf of the stupid. Having some bar doesn't seem unreasonable.

>If people in the US try to turn climate action into a blame game, it will end very very poorly for the US. Pure fantasy. What will happen to the US and who will do it to us?

The US can't even get countries to enter trade agreements anymore, because it's throwing around threats of large tariffs and annexation of others' lands. The world could drop the dollar as the reserve currency, something that was gradually happening but is now accelerating. If the US starts trying to force other countries into climate action without taking into account its own contributions, the US will likely cut ou…

The US defines the terms of the vast majority of global trade agreements and there’s no indication that will ever change. Americans get it — global academia hates Trump and to some extent America itself. In a way it’s understandable because you all seem to believe in your “right” to pick winners and losers. The world doesn’t actually work that way.

Why does NASA even have to do this? Build some cool rockets and get us to mars.

Living on Mars long-term is a practical impossibility. Certainly much, much harder than living on even a climate-changed Earth.

I’ve been living on a climate-changed earth for my entire life and it’s not been too difficult.

fossil fuels were a proxy for energy. China continues to show the world that energy independence can come via electricity that you generate within your borders, and that it can be cheaper than importing foreign oil.

China is in no way energy independent. Their fossil fuel imports are extremely high and not decreasing.

China's gasoline use is down substantially. Industrial use is up, but much of that is re exported via plastic etc.

The earth did have warm periods before. it appears to be part of an mini-interglacial period which happens every few hundred years. We had the Medieval Warm Period, the Roman WP and Bronze age warm period. There is a vast body pf evidence in particular for the MWP showing that life on earth got better as the deserts retreated.

This is a nice graph that makes the problem pretty obvious: https://xkcd.com/1732/

I accept radiative physics. I question whether we have correctly quantified the system's natural noise floor, and whether adaptation might outperform mitigation for human flourishing.

A troll response I presume. Or perhaps sarcasm without the indicator.

Not a troll comment. China produces as much or more CO2 as much as the next 5 countries combined. It's logical to start with the king of greenhouse emissions if you want to stop global warming.

Nothing? China is solving the problem on their own. They already make substantially less carbon per person that most of the west. If we want to be like China it's a simple proposition: be OK with Manhattan project level investments in power transmission from places that have lots of renewables to places that need renewables.

Climate is determined by total CO2 output, not per capita. That’s a real problem, because China, and all the poor countries in Asia and Africa aren’t going to stop increasing their CO2 output per capita until they reach western standards of living.
