Global Warming Might Cook Up Too Many Male Fish
Many reptiles have no sex chromosomes. Instead, their gender is determined by temperature. In crocodiles, for example, males are hot: eggs incubated in sand above a certain “pivotal temperature” almost always hatch males. That could spell trouble, because Earth is warming so fast that natural selection may not have time...

Oceans Running Low on Oxygen
Parts of the world's oceans are running low on oxygen, a new study finds. Fertilizers and other chemical pollutants in river runoff fuel blooms of algae that cause oxygen levels to dip precipitously when they die. A review of research into these so-called dead zones, detailed in the Aug. 15...

Tropical Trouble: Species to Struggle in Heat
Polar bears may be the poster children for the havoc that climate change could wreak on sensitive species, but animals and plants in the tropics could actually be in the greatest peril from global warming, a new study suggests. While temperature changes in the tropics are expected to be much...

Runaway Global Warming 635 Million Years Ago
A sudden and extreme case of runaway global warming 635 million years ago was caused by an abrupt release of methane, a powerful greenhouse gas, scientists said today. The methane seeped from ice sheets that covered much of the planet toward the end of a frigid era called Snowball Earth....

The Most Surprising Results of Global Warming
At the United Nations meeting on climate change next week, scientists will be discussing some of the potentially devastating effects of global warming, such as rising temperatures, melting ice caps and rising sea levels in the near future. But Earth's changing climate is already wreaking havoc in some very weird...

The Reality of 'Climategate'
At a Danish climate summit this week, one subject will certainly be raised: The theft of thousands of private e-mails and files recently hacked from computers at East Anglia university, a leading climate research center. The e-mails, which were made public and appear to show scientific misconduct, have fueled a...

Gravestones Hold Secrets to Earth's Climate Past
Gravestones may hold secrets of how the Earth's atmosphere has changed over the centuries, and scientists are now asking for the public's help to read these stones. Little by little, atmospheric gases dissolved in raindrops cause the marble in gravestones to erode. As such, headstones can serve as diaries of...

Time-Lapse Photos Show Dramatic Erosion of Alaska Coast
SAN FRANCISCO — Time-lapse photography of crumbling Alaskan coastlines is helping scientists understand the triple whammy of forces eroding the local landscape: declining sea ice, warming ocean waters and more poundings by waves. The erosion rates from these forces are greater than anything seen along the world's coastlines, with the...

Arctic Ice at 3rd Lowest in Recent Decades
The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center. Scientists have been watching the ice return with less...
