Echoing the kind of climate change scenario 5 year old kids have seems kind of cruel the week thousands of people in Libya died of events that are exasperated by the climate crisis. People are already dying of climate related causes, like crop failures and natural distasters.

Man-made dams broke.

Right? The climate is fine as long as you don’t depend on man made objects

How is something critical if it has been transgressed and we are still alive? Or on the very first moment every single one is past we all suddenly die?

Ha, good point, let's not focus on the main issue and instead argue semantics shall we... /s To ELI5 like you seem to prefer, the iceberg breaching the hull of the Titanic seems like a critical transgression, but the ship stayed afloat another hour or so...

They are not arguing semantics, they are getting to the very premise/context of the paper.

What happens to the environment is not governed by "humanity's best interest", it's governed by whomever has the most power and the biggest stick. These entities act in their own best interest.

Everyone acts in their own interests. The gilets jaunes were a grassroots protest against a gas tax increase. You see similar gas-station sticker-shock pressure exerted by voters in the United States.

There are coordination problems to climate change. But it's less a prisoner's dilemma than a time-horizon problem: the fruits of a green transition won't yield for decades. (Economies of scale help with this. Geopolitical decoupling gets in the way of that--this is the only domain where I see the prisoner's dilemma that you allude to.)

What you are saying is technically not wrong, but misleading, as it omits the fact the dams broke due to a natural disaster, Storm Daniel, which previously also "affected Greece, Bulgaria, and Turkey with extensive flooding.".

pretty sure we have enough solar and batteries to power the world. Sure ok we could use nuclear in some places too. aerosols... that's from burning fossil fuels, no? fake meat will go a long way to reclaiming farmland.

micro / nano plastics everywhere sucks. going to have to think hard about how to fix that one.

can we take cell samples of all the species just in case we need to conjure them up again? (or is at least one required to "boot")

Give it some time. Good news is that "faster than expected" seems to be a very common saying among people studying these areas, so you might not have to wait as long as the geological time might suggest!

Honestly, as someone who has been very concerned about climate for a while now, I'm surprised how much visible disruption of the climate system we've directly been able to observe. Earlier in my life I thought that, though dire, this was certainly a problem that would impact future generations but not so much ours. It turns out I might have been quite wrong on that front.

No kidding, but to say that climate change did this when hurricanes have been on the decline the last thirty years is misleading. This is weather and engineering failures. https://www.nature.com/articles/s41467-021-24268-5
