National security threatened by climate crisis, UK defence chiefs due to warn

Report by joint intelligence committee delayed, with concerns expressed that it may not be published

The UK’s national security is under severe threat from the climate crisis and the looming collapse of vital natural ecosystems, with food shortages and economic disaster potentially just years away, a powerful report by the UK’s defence chiefs is due to warn.

However, the report, which was supposed to launch on Thursday at a landmark event in London, has been delayed, and concerns have been expressed to the Guardian that it may not now be published.
