Well it depends where you live. Many people have already had to leave their homes. It is reckoned that the Syria war was caused by climate change. People from the country unable to grow their food eventually got very cross and went into the cities and from that things sparked off.
But it is pretty much here now for us all. In the IPCC's latest report
Climate Change 2022: Impacts, Adaptation and Vulnerability
they say that if we do not change our usage of fossil fuels in only 8 years we will be at 3 degrees warming. Sadly I believe that will happen as I do not see Governments in a panic to stop this happening, even though most will still be alive. instead we are playing at wars one of the worse things for the climate. Too busy playing at being big boys to do the decent thing and provide a liveable world for everyone who will be alive in 8 years and after.
(It is worth pointing out that until now the IPCC's reports have always erred on the side of saying things would be less bad than they turned out to be.)
