We have always warned that climate change threatens national security because of the consequences for destabilisation of entire regions of the world, mass migration of millions of people and conflict over water or food supplies.

But the events of the last few weeks have shown this is a national security issue in our own country too with people's homes, businesses and livelihoods coming under attack from extreme weather. And we know this will happen more in the future.
