Energy production of all types — wind, ethanol and mountaintop coal mining — is contributing to steep drops in bird populations, a new government report says. The first-of-its-kind report chronicles a four-decade decline in many of the country's bird populations.
A drastic climate shift such as a thaw of Greenland's ice or death of the Amazon forest is more than 50 percent likely by the year 2200 in cases of strong global warming, according to a survey of experts.
The poll of 52 scientists, looking 100 years beyond most forecasts, also revealed worries that long-term warming would trigger radical changes such as the disintegration of the ice sheet in West Antarctica, raising world sea levels.
According to the Department of Energy, there is enough spent nuclear waste in the United States to fill a football-field-sized hole 15 feet deep. From a plethora of proposals, scientists and politicians have selected on-site storage as the safest solution for the buildup. But it's a temporary solution. The waste will be fatal to humans and other animals for tens of thousands of years — yet the storage tombs are expected to last only a hundred years.
These scattered nuclear graveyards are emblematic of a failed U.S. nuclear energy policy — a policy that is rarely discussed even as regulators entertain proposals to build roughly 30 new nuclear power plants.
Global warming will wreck attempts to save the Amazon rainforest, according to a devastating new study which predicts that one-third of its trees will be killed by even modest temperature rises.
More bad news on climate change is expected as more than 2,000 climate scientists gather in Copenhagen.
The scientists are concerned that the 2007 reports of the Intergovernmental Panel on Climate Change (IPCC) are already out of date. Their data suggests greater rises in sea levels this century.
We are experiencing an accelerated obliteration of the planet’s life-forms—an estimated 8,760 species die off per year—because, simply put, there are too many people. Most of these extinctions are the direct result of the expanding need for energy, housing, food and other resources.
