When 64-year-old Jimale Irobe was a young man, he guided his herds of cows and camels through knee-high grass.

And a September report by the International Food Policy Research Institute predicted that the worldwide effects of climate change will lead to twenty-five million additional children becoming malnourished by 2050.
