Of course Climate Change is not the End of the World. It has the potential to be the end of Humans (if taken to it logical conclusion). It would be the end of safe and easy access to some food, some water, and some occupied locations.
If the plural multi Celsius degree increases occurs, there was predictions of Southern Canada becoming the new bread basket, except that 340 million USAsians don’t live in Canada. If average sea level increases enough, half of coastal and port cities get destroyed every time there’s a storm search (Like New Orleans, but much more frequent).
The World will continue on, but potentially not with 8+ billion humans with it.
