Honestly....we're pretty much already past the point of no return now.
The only thing anyone can do is try to limit how hellish hell gets to be.
The difference between a 3 degree warming and worst case 8 degree warming is pretty immense. 8 degrees is the end of human civilisation.
3 degrees is still immensely shit but not doomsday.
People are right though - stopping at 2.5-3 degrees change requires MASSIVE changes. We're talking about every single person in Western countries reducing their living standards by 30% and developing countries stopping development.
The only way that will happen is when the shit really starts to hit the fan....obviously we're already starting to see the impact with huge wildfires, increase in the number and intensity of hurricanes, deaths in heatwaves, etc....but I mean Govts won't legislate to the degree needed until things are ten times worse than this.
By then it will be too late 🤷🏻♀️
Looking on the bright side we (UK) will be less impacted by climate change than most of the world. I foresee in 30-40 years we'll close our borders to climate refugees (and immigrants), have an authoritarian Govt with a shoot to kill policy for any refugees trying to get into the country, rationing (forever), etc.
There will be a huge influx of people moving further North in Canada, Russia, Greenland, etc.
Southern Europe, South & Central America and the southern US states as well as much of Australia will be desert. The Amazon will be gone.
This is all in the IPCC climate change report - not some kind of fanciful story.
If people think there immediate problems are more pressing than this they're most likely wrong. Our children will be living in a different world to us.
