TED.com talk Like all predictions of the future the precis nature of the scenario will be different and the timing may be out. BUT ...............

with global warming as fact (debate the cause not the observation - please) there will be a squeeze, if not called a crisis. And almost (I hope) in my lifetime.
We have wars over water supply, which is directly about food production. The usable geography of a given food production is moving away from the equator. New Scientist reports findings: yields will reduce too.

The talker above talks in calories not tonnage and Africa is thus a net importer of calories. China is a net exporter, compare that to the BBC R4 Extra programme from a journalist who lived through the excesses of Mao and didn't see the full extent of starvation until after. (30 Million deaths - 5% of population).
They learned, will we?

Surely with "global warming as a fact" any discussion based on a lack of 'calories', and a future shortage of 'calories' is doomed to failure.

Weather extremes hit crop yields. In a warming world with more extreme events crops become increasingly vulnerable. A starting point below.

Dunno about food risks. I've just been reading about Bangladesh. Almost the whole country is below twelve metres above sea level and much of it is a lot lower than that. The population of the country is already fully half that of the United States and going up. Global warming, sea level rise, anyone?
