David Wasdell, Director of the Meridian Programme, a world-renowned expert in the dynamics of climate change, delivered the bad news.

Consequently, not only will every tonne of CO2 emitted from now on have to be recovered and sequestered before its full heating effect has developed but some past emissions will have to be recovered too.
