Drought
The Intergovernmental Panel on Climate Change’s (IPCC) Fourth Assessment Report predicted that there’s a 66 percent chance that there will be a rise in the number of droughts around the world because the air’s temperature increases and is able to hold larger amounts of water, making crops scarce and raising the prices of groceries. “As time goes on, the poor countries that are in the warmer and drier parts of the planet will feel the crop yield decreases early,” said Michael Oppenheimer, professor of geosciences and international affairs at Princeton University. “When you get above two degrees and into the three- and four-degree range, adaptation becomes less effective, and even some of the wealthy countries that have advanced agriculture start suffering.”
