"would go back to normal"

But what is normal? The climate we are prepared to cope with in our modern lifes? The climate we built our houses* for and designed our ACUs?

Or 'normal' such as in the past period of a couple of million years with hugh recurring changes?

We are definitely not doomed, no matter how real or irreversible or human-made global warming is. It is simply a question of natural selection: those who are able to fit with the change will survive - be it animals, plants, human beings or politicians and journalists.

*not exactly in the UK. British houses were surely built for the warm future climate which we will soon suffer from or enjoy; all depends on the individual attitude.
