It is the black before dawn at the gate to the Kanha Tiger Reserve, in the highlands of central India. The still air carries a dank, penetrating chill. But it is hardly quiet. A buzzing line of tourists is forming at the ticket booth, peddlers are pouring steaming cups of tea. Groups of green-uniformed rangers chat… read more
The onset of flu season each year comes as no surprise. But what is surprising is that we don’t know exactly how the flu spreads. Jeffrey Shaman is working on that.
A warming climate is not just melting the Arctic’s sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country’s waters, says a new study.
Christine McCarthy, a geophysicist at the Lamont-Doherty Earth Observatory, scrunches blocks of ice between hunks of rock to study how ice behaves under pressure. Her work provides an important piece of the puzzle of how glaciers move, what makes them speed up, and how they are contributing to sea level rise as the climate warms.
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.
