10,000 simulations show warming range of 1.4 to 3 degrees by 2050
Posted: 03 Apr 2012 11:04 AM PDT
A project running almost 10,000 climate simulations on volunteers' home computers has found that a global warming of 3 degrees Celsius by 2050 is 'equally plausible' as a rise of 1.4 degrees.
Coral links ice sheet collapse to ancient 'mega flood'

Coral off Tahiti has linked the collapse of massive ice sheets 14,600 years ago to a dramatic and rapid rise in global sea-levels of around 14 meters.
Is bioenergy expansion harmful to wildlife?
Posted: 03 Apr 2012 08:18 AM PDT
Despite the predicted environmental benefits of biofuels, converting land to grow bioenergy crops may harm native wildlife. Researchers have developed a way to study the effects of increased energy crop cultivation
on farmland bird populations.
