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.

If emissions of greenhouse gases remain high, as many as 143 million “internal migrants” might move within their own countries by 2050.
Andrew Robertson is creating a forecasting system that will help societies adapt and become more resilient to the impacts of climate change.
Soil naturally absorbs a huge amount of carbon. Some scientists think we can use it to our advantage in the fight against global warming.
If carbon emissions hold steady, a new study in Science predicts that the European Union could face a massive influx by 2100.
A chronological guide to key talks and other events presented by Columbia University’s Earth Institute at the American Geophysical Union 2017 meeting.
Every four years Congress is provided with a state-of-the-art report on the impacts of climate change on the United States. The next National Climate Assessment is scheduled for 2018, but its scientific findings are scheduled to be published today. Here, two of its authors explain what to expect.
Human-influenced climate warming has already reduced rainfall and increased evaporation in the Mideast, worsening water shortages. Up to now, climate scientists had projected that rainfall could decline another 20 percent by 2100. But the Dead Sea cores suggest that things could become much worse, much faster.
A thousand years ago, powerful Viking chieftans flourished in Norway’s Lofoten Islands, above the Arctic Circle. In an environment frequently hovering on the edge of survivability, small shifts in climate or sea level could mean life or death. People had to constantly adapt, making their living from the land and the sea as best they could.
The rise of the Vikings was not a sudden event, but part of a long continuum of human development in the harsh conditions of northern Scandinavia. How did the Vikings make a living over the long term, and what might have influenced their brief florescence? Today, their experiences may provide a kind of object lesson on how changing climate can affect civilizations.
