Billions could go hungry by 2100 due to global warming

post #1 of 3

David Battisti, Professor of Atmospheric Sciences at the University of Washington led a study (published in Science magazine) which focused on temperatures during growing seasons around the world, which allowed them to determine the effect on food supplies.

Their results show there is a 90% chance that average temperatures in the tropics and subtropics will be higher than the hottest heat waves of the past century. With more than 3 billion people living in those areas, most of whom rely heavily on locally produced crops for both food and income, the effects could be catastrophic.

Oh dear...that's pretty scary.  And in 91 years, who knows what will be going on with the health of the oceans.  So all of those people who rely on fish, etc to feed themselves...they might not have too many options either.

That's true, particularly when you consider ocean acidification.

 

This story goes along with the fact that the California state Dept of Water Resources recently announced that we may be on the verge of the worst drought in California history, and California is the largest agricultural producer in the country.

 

Steven Chu also recently said

 

"I don't think the American public has gripped in its gut what could happen," he said. "We're looking at a scenario where there's no more agriculture in California." And, he added, "I don't actually see how they can keep their cities going" either.
