In an unusual new study, scientists say they have detected a growing fingerprint of human-driven global warming on global drought conditions starting as far back as 1900.

Access to adequate fresh water supplies is a critically important societal challenge posed by climate change. With rising heat and shifting rainfall patterns, and reduced water storage resilience, fresh water supplies are already diminishing in the western United States, Mexico, the Middle East, and Mediterranean. Water shortages have been implicated in recent international conflict, and a recent Department of Defense study underscores the geopolitical importance of this problem.

Aaron Putnam sits atop a boulder high in the Sierras of central California, banging away with hammer and chisel to chip out a sample of ice age history. Each hunk of rock is a piece of a vast puzzle: How did our climate system behave the last time it warmed up like it’s doing today?

As the American Southwest grows hotter, the risk of severe, long-lasting megadroughts rises, passing 90 percent likelihood by the end of the century if greenhouse gas emissions continue at their current pace, a new study says. If we aggressively reduce greenhouse gas emissions, however, we can cut that risk substantially, the authors write.
