Forests of genetically altered trees and other plants could sequester several billion tons of carbon from the atmosphere each year and so help ameliorate global warming, according to estimates in the journal BioScience.
The study, by researchers at Lawrence Berkeley National Laboratory and Oak Ridge National Laboratory, outlines a variety of strategies for augmenting [...]
The soils in large areas of the Southern Hemisphere, including major portions of Australia, Africa and South America, have been drying up in the past decade, a group of researchers conclude in the first major study to ever examine “evapo-transpiration” on a global basis.
Most climate models have suggested that evapo-transpiration, which is the movement of [...]

That doesn’t sound much, but as well as warmer days and nights, rising sea [...]
Only about 7% of South Africa has a mean annual precipitation or MAP exceeding 800 mm. When the statistics are reviewed they indicate that KwaZulu-Natal is the wettest province, while the Western Cape has the highest variability of MAP within any of the provinces, and the highest individual point rainfall at an estimate of 3345 [...]

Dawie Groenewald, 42, the wealthy driving force behind Out of Africa Adventurous Safaris in Polokwane, his wife, Sariette, 34, and Tielman Erasmus, a [...]
Forget number crunching weather simulations. It now turns out tracking where termites build their mounds can help to predict climate change.
By using an airborne mapping system, scientists at the Carnegie Institution’s Department of Global Ecology mapped more than 40,000 termite mounds across 192 square miles in South Africa’s Kruger National Park.
The September 7 research, published [...]
