Fact check: Tim Spector’s frightening climate claims

The BBC just can’t seem to stop itself trying to frighten people over climate change. On Tuesday morning it was the turn of Radio 4’s Food for Life by King’s College London professor Tim Spector. The show began with an extraordinary claim: ‘Most predictions concur that if we don’t change our habits fast, by 2050 the Earth will have lost most of its trees and habitable areas.’

Really? I contacted Spector over where he sourced this claim and was told that the claims were ‘in the IPCC reports’. But are we really on course to lose most of our trees in just 26 years’ time? The IPCC’s latest Special Report on Climate Change and Land does not appear to make any confident prediction for future tree cover, and there is not a lot of support for Spector’s claim from data from the UN Food and Agriculture Organisation.
