But lately, nothing concerns Grantham more than climate change and its effects on commodity prices and food supplies.
He discusses it in a new piece for Nature.com:
I have yet to meet a climate scientist who does not believe that global warming is a worse problem than they thought a few years ago. The seriousness of this change is not appreciated by politicians and the public. The scientific world carefully measures the speed with which we approach the cliff and will, no doubt, carefully measure our rate of fall. But it is not doing enough to stop it. I am a specialist in investment bubbles, not climate science. But the effects of climate change can only exacerbate the ecological trouble I see reflected in the financial markets — soaring commodity prices and impending shortages.
One of the most urgent aspects of this impending crisis is the shrinking supply of fertilizer, most of which comes from just three parts of the world.
