The highlands of Ethiopia are home to the majority of the country’s population, the cooler climate serving as a natural buffer against malaria transmission. New data now show that increasing temperatures over the past 35 years are eroding this buffer, allowing conditions more favorable for malaria to begin climbing into highland areas.
In the 2004 disaster movie “The Day After Tomorrow,”, global warming accelerated the melting of polar ice, disrupting circulation in the North Atlantic Ocean and triggering violent changes in the weather. Could climate change shut down the Gulf Stream?
A new analysis of global satellite observations shows that vegetation can powerfully alter atmospheric patterns that influence climate and weather.
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 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.
