Two new papers find that the line that divides the moist East and arid West is edging eastward due to climate change—and the implications for farming and other pursuits could be huge.
The landlocked are surrounding the Dead Sea suffered long megadroughts in the past. Now, climate change threatens to inflict such conditions again on this already sere, volatile region.
Humans migrated out of Africa to escape a drying climate, about 60,000 years ago, according to a new study in the journal Geology.
Richard Seager and Park Williams discuss how water will be affected by warmer temperatures, and how their research increases understanding of these issues.
Seager, a climate scientist at Lamont-Doherty Earth Observatory, discusses his research on drought in the North American Southwest.
How did our climate system behave the last time it warmed up like it’s doing today?
Park Williams explains the influence of climate change on droughts and wildfires in the western United States.
A new study says that human-induced climate change has doubled the area affected by forest fires in the U.S. West over the last 30 years.
As the Southwestern U.S. grows hotter, the risk of long-lasting megadroughts rises, passing 90% this century if greenhouse gas emissions continue at their current pace.
Scientist Park Williams, recipient of a Climate and Life Fellowship, is examining the influence of climate change on droughts and wildfires.
One scientist is focusing on food security and climate shocks. The other is exploring the influence of climate change on droughts and wildfires.
Using tree rings, a new drought atlas maps the reach and severity of dry and wet periods across Europe and the Mediterranean over the past 2,000 years.
Ancient pollen is providing new insights into historic droughts in Southern California, including how a series of mega-droughts that changed the ecological landscape.
A new study by Lamont-Doherty Earth Observatory scientists says a record drought that ravaged Syria in 2006-2010 was likely stoked by ongoing manmade climate change, and that the drought may have helped propel the 2011 Syrian uprising.
During the second half of the 21st century, the U.S. Southwest and Great Plains will face drought worse than anything seen in times ancient or modern, a new study says.
