Photo Essay: The Dead Sea, Living Waters and Megadrought
Thousands of years before Biblical times, during a period when temperatures were unusually high, the lands around the Dead Sea now occupied by Israel, Jordan and surrounding nations suffered megadroughts far worse than any recorded by humans. Warming climate now threatens to return such conditions to this already hard-pressed region.

Rising Temperatures Load the Dice for Megadrought Risk
As the American Southwest grows hotter, the risk of severe, long-lasting megadroughts rises, passing 90 percent this century if greenhouse gas emissions continue at their current pace, a new study from scientists at Lamont-Doherty Earth Observatory says. Aggressively reducing emissions can cut that risk.

Learning from El Niño as La Niña Odds Rise
Although El Niño is weakening, its ramifications continue to be felt around the world. Drought and resulting food insecurity is one of the major implications for southeast Asia, eastern and southern Africa, Central America and the Caribbean. Sixty million are in need of emergency relief today, according to the United Nations.
