Bjørn Lomborg, a self-styled “sceptical environmentalist” who has long opposed international curbs on carbon emissions, is now urging world leaders to invest heavily in clean energy.
Erm, that’s not actually a great change from his previous views.
In fact, I don’t see it as a change at all. He has always said that climate change is happening and that we’re causing it. He’s also always bought into the basic economic approach: either a carbon tax or cap and trade plus adaptation. Mitigation only makes sense so far as it it improves the general lot of mankind.
He’s also always said that over and above this there should be government led R&D into non and low carbon technologies. This is all in his first book so I really don’t see what the change is.
