Before anyone can answer the question: "Are we doomed?," we must determine who "we" is, and what "doomed" means. If we take it to mean the near-term extinction of our species, there's no reason to believe that will happen, even if the worst of the projected climate scenarios occurs between now and the end of the century. That being said, some people are doomed. Even under the most optimistic climate scenarios, sea levels will continue to rise, heat waves will become more severe and more frequent, as will wild fires, floods, droughts, etc. Some people will die as a result of these natural disasters. Which people? It's more likely to be people who live in relatively poor, unstable countries, and less likely to be people who live in relatively wealthy, stable countries.

The long and short of it is: some people are doomed, but many, if not most people, will probably be just fine.

I don't know about irreversibly, but the remarkable and consistent gains in solar technology especially are extremely exciting.

As soon as one of these prototype next-gen batteries hit, that's it for fossil fuel.

It's already not worth it to continue using fossil fuel commercially, but as soon as the next-gen power storage is able to be produced on scale, power plants are changing, phones, computers, cars, everything's going to change.

I can't see that being more than a decade out, but even if nexgen battery tech doesn't hit, the constant improvement on s***** traditional battery tech now is improving rapidly.

It is a very exciting time and energy production and storage.

That is uplifting news! Thanks for sharing!

Ooh, too bad big tech is devouring all that renewable energy (and then some) for forcing unwanted AI into our everything, making even more fossil fuel consumption necessary. That's okay though. Over made my peace with our inevitable extinction.
