Human-induced climate change reduces chance of flooding in Okavango Delta
Researchers at the University of Cape Town, Berkeley Lab and the United Nations Development Programme have analyzed how human-induced climate change has affected recent flooding in an ecologically and geographically unique river basin in southern Africa—the Okavango River. After running a number of simulations, they found that greenhouse gas emissions have substantially reduced the chance of the floods in the region. Read More »
A New Mathematics for Experimental Science
In the age of high-resolution detectors and international research collaborations, math has the potential to transform science and accelerate discovery.
