The window to address the threat of Climate Change is closing rapidly. A half-billion people already live in places turning into desert, and soil is being lost between 10 and 100 times faster than it is forming. Floods, drought, storms and other types of extreme weather threaten to disrupt, and over time shrink, the global food supply.
A particular danger is that food crises could develop on several continents at once. The potential risk of multi-breadbasket failure is increasing. Food shortages are likely to affect poorer parts of the world far more than richer ones. That could increase a flow of immigration that is already redefining politics in North America, Europe and other parts of the world. Between 2010 and 2015 the number of migrants from El Salvador, Guatemala and Honduras showing up at the United States' border with Mexico increased fivefold, coinciding with a dry period that left many with not enough food and was so unusual that scientists suggested it bears the signal of climate change.Around the World

Higher concentrations of carbon dioxide in the atmosphere will also reduce food's nutritional quality. On the whole, even with longer growing seasons, climate change is already hurting the availability of food. One point, soon, we will reach a breaking point with land itself and its ability to grow food and sustain us.
