Global experts: Warming could double food prices

CANCUN, Mexico — Even if we stopped spewing global warming gases today, the world would face a steady rise in food prices this century.

But on our current emissions path, climate change becomes the "threat multiplier" that could double grain prices by 2050 and leave millions more children malnourished, global food experts reported Wednesday.

Beyond 2050, when climate scientists project temperatures might rise to as much as 11.5 degrees over 20th century levels, the planet grows "gloomy" for agriculture, said senior research fellow Gerald Nelson of the International Food Policy Research Institute.

The specialists of the Washington-based institute said they fed 15 scenarios of population and income growth into supercomputer models of climate and found that "climate change worsens future human well-being, especially among the world's poorest people."

The study, issued the annual U.N. climate conference, said prices will be driven up by a combination of factors: a slowdown in productivity in some places caused by warming and shifting rain patterns, and an increase in demand because of population and income growth.

Change apparently already is under way. Returning from northern India, agricultural scientist Andrew Jarvis said wheat farmers there were finding warming was maturing their crops too quickly.
