The American Geophysical Union fall meeting takes place Dec. 10-14 in Washington, D.C. Here is a guide to key talks and other events from Columbia’s Earth Institute.
drought Archives - State of the Planet
Park Williams, a bioclimatologist at Lamont-Doherty Earth Observatory, has found that rising temperatures influence wildfires in the American West.
The Global Famine was one of the worst humanitarian disasters in history, killing as many people as World War II. A new analysis suggests it could happen again, only worse because of climate change.
An interview with Ed Cook, one of the founding directors of the Tree-Ring Laboratory at Lamont-Doherty Earth Observatory.
As the world population continues to grow, global demand for food could increase dramatically by 2050. Yet the impacts of climate change threaten to decrease the quantity and quality of our food supplies.
Scientists are unraveling the driving forces of one of the worst environmental disasters in human history, in hopes of predicting and preparing for the next global drought.
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.
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.
Richard Seager and Park Williams, climate scientists at Lamont-Doherty Earth Observatory, discuss how water will be affected by warmer temperatures, and how their research increases understanding of these issues.
Colin Kelley, an associate research scientist with the International Research Institute for Climate and Society, studies regional climate in vulnerable areas like the Middle East in order to improve our ability to make forecasts, plan ahead and become more resilient to drought and other climate shifts.
