If U.S. sulfur dioxide emissions are cut to zero by 2100, as some researchers have projected they will be, rainfall over Africa’s Sahel region could increase up to 10 percent from 2000 levels, computer simulations suggest.
For years, scientists have been warning of a so-called “hot spot” of accelerated sea-level rise along the northeastern U.S. coast. But accurately modeling this acceleration as well as variations in sea-level rise from one region to another has proven challenging. Now new research offers the first comprehensive model for understanding differences in sea level rise along North America’s East Coast.
In recent years, scientists have revealed that we are depleting our global groundwater reserves at an alarming rate. Now researchers have shown that a significant share of this unsustainable water use fuels the global food trade, which means water exhaustion in supplier nations could ripple outward, causing food crises half way across globe.
For Mexico City’s biggest businesses and its poorest neighborhoods, rainwater harvesting could help address an enormous water crisis plaguing the city, a recent Columbia Water Center study found.
A new paper shows that rising temperatures have increased the risk of fires even during non-drought years in Indonesia, possibly making mild fire seasons in the country a thing of the past.
Cities in the developing world may soon see dramatic spikes in electricity consumption for heating and cooling, according to a new study led by researchers from the Earth Institute’s Quadracci Sustainable Engineering Lab.
Michelle Ho grew up in Australia, the driest inhabited continent, with an appreciation for the value of having a clean glass of water to drink. Now, she conducts research for the Columbia Water Center on America’s water systems.
A new four-step “framework” aims to test the contribution of climate change to record-setting extreme weather events.
The word fossils typically conjures images of T-Rexes and trilobites. Pratigya Polissar thinks micro: A paleoclimatologist, he digs into old sediments and studies molecular fossils—the microscopic remains of plants and animals that can tell us a lot about what was living in a particular time period.
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.
