We will see millions of people relocating due to climate change, so if you enjoy the idea of far more people coming to our shores than they do currently, then continue not caring. This is in a time frame of most people's lives, and is avoidable. Whereas an asteroid type disaster is not expected in any reasonable timeframe.
What my personal impact is, is unimportant. For example, I'm not going to judge an American who lives in a car centric city, where they have to drive to do anything. They live in a high carbon economy. The UK is heading towards that in many ways, despite taking measures to counter it. There is little they can do to change that system in which they live. Short of voting for someone who will change things, or pushing those in power to do the right thing.
I do cycle most places, but I'm not going to judge people that don't. Most people I work with live too far from work to do this.
So people will come to the UK because they are being fried to death elsewhere... Can you give any examples of where this is happening? Or when it will happen?
Presumably if they're all fried to death we won't have anything to worry about... or, wait, won't the sea levels have risen to quench all the burning flames?
I'm losing count of the bizarre, doom laden scenarios. Didn't some plonker at the UN say there would be global boiling? Will that be existing liquids or will all solids enter a molten phase?
