An unusual substance known as "dry water," which resembles powdered sugar, could provide a new way to absorb and store carbon dioxide, the major greenhouse gas that contributes to global warming, scientists reported at the 240th National Meeting of the American Chemical Society. The powder shows bright promise for a number of other uses, they said. It may, for instance, be a greener, more energy-efficient way of jump-starting the chemical reactions used to make hundreds of consumer products....

Research by scientists at Queen Mary, University of London has found that a predicted rise in global temperature of 4°C by 2100 could lead to a 13% reduction in ecosystems' ability to absorb carbon dioxide (CO2) from the atmosphere. Writing in Philosophical Transactions of the Royal Society B, the scientists describe a new model to predict how the carbon storage capacity of ecosystems would respond to future global warming. They tested their predictions against data collected from...
