What does obesity have to do with climate change? Plenty, say some ...

While climate change reduces food production through drought and flood, replacing costly healthy foods with cheaper ones promotes obesity.

… A rise in food prices caused by climate change will lead to higher, not lower, obesity rates in the United States. The spikes in food prices observed in 2008 and again in 2010 were highest for the healthier foods, particularly vegetables and fruit. The current drought conditions have damaged crops and will lead to food-price increases in 2013, especially for dairy, eggs, and meat. As food prices continue to increase, refined grains, added sugars, and vegetable fats will replace healthier options, first for the poor and later for the middle class.
