I actually don't see climate change as the most immediate threat because we can come up with strategies to mitigate the worst of its effects. Things like severe weather, greater sea levels etc can all be somewhat mitigated and it's a slow change that will happen progressively over a long period.
What is never discussed at these conferences though is the real problem and that's the destruction of the natural environment. For example, people keep going on that we'll be able to give up meat and eat insects to reduce Co2, however the fact is that insect populations have declined by over 40% in just 30 years! In 50 years time there will be no insects left.
I think you can see it on this forum where the irony of it all is we moan about climate change but then we moan about the price of houses and how we need to build more of them which destroys the environment further.
With all of this in mind it's obvious why it isn't going to work because we are too busy thinking about how much electric cars will cost instead of thinking how we can do without having a car at all. Again it's ironic that Prince William passed on getting the Range Rover built up the road to his Earthshot conference but he happily took an £80k electric Audi. This is an Audi that was no doubt built in a carbon guzzling factory in Germany, sent on a carbon guzzling ship to his front door. Why didn't he just get the train?
Perhaps the only way technology will save us is thanks to people like Elon Musk who acknowledges the planet is eventually going to be stuffed so he's coming up with as many ways as possible to get us off it....
The ongoing sixth mass extinction may be the most serious environmental threat to the persistence of civilization, because it is irreversible. Thousands of populations of critically endangered vertebrate animal species have been lost in a century, indicating that the sixth mass extinction is...
