Rising seas from global warming, coming after years of coral reef destruction, are forcing thousands of indigenous Panamanians to leave their ancestral homes on low-lying Caribbean islands. Seasonal winds, storms and high tides combine to submerge the tiny islands, crowded with huts of yellow cane and faded palm fronds, leaving them ankle-deep in emerald water…

BP Plc removed a containment cap from its stricken Gulf of Mexico oil well on Saturday in the first step toward installing a bigger cap to contain all the crude gushing into the sea and fouling the coast. The maneuver released a torrent of oil that will spew unrestrained into the Gulf for four to…

Exporters, livestock feeders and ethanol makers are going through the U.S. corn stockpile faster than farmers can grow the crops, the government said on Friday. Despite record crops in two of the past three years and another record within reach this year, the Agriculture Department estimated the corn carryover will shrink to the lowest level…

Integrated environmental modeling is a discipline of developing a system of models where models from two or more academic disciplines are integrated such that they behave like a unit to external stimuli. At least one of the models in the system is from environmental domain while others may come from other academic disciplines such as…

The polar bear has long been a symbol of the damage wrought by global warming, but now biologist Andrew Derocher and his colleagues have calculated how long one southerly population can hold out. Their answer? No more than a few decades, as the bears’ decline closely tracks that of the Arctic’s disappearing sea ice.

A provocative new study suggests that mice raised in spacious cages with lots of toys and companions are more resistant to cancer than mice living in standard cages. The work, which finds that exercise alone doesn’t explain the anticancer effect, is drawing both excitement and skepticism.

A giant glider-like aircraft has completed the first night flight propelled only by solar energy, organizers said on Thursday. Solar Impulse, whose wingspan is the same as an Airbus A340, flew 26 hours and 9 minutes, powered only by solar energy stored during the day. It was also the longest and highest flight in the…

Upper atmospheric lightning or upper atmospheric discharge are terms sometimes used by researchers to refer to a family of electrical breakdown phenomena that occur well above the altitudes of normal lightning. The preferred current usage is transient luminous events (TLEs) to refer to the various types of electrical discharge phenomena in the upper atmosphere, because…

I have to bite my tongue when I hear people claim how progressive Europe is when it comes to sustainability and consumerism. Take Amsterdam, where in May I worked and traveled for two weeks. True, bicycles are everywhere, public transport works, and you can find great locally grown food. But step into an Albert Heijn…

The surest sign of a warming Earth is the steady melting of its ice zones, from disappearing sea ice in the Arctic to shrinking glaciers worldwide. Now, scientists are using increasingly sophisticated satellite technology to measure the extent, thickness, and height of ice, assembling an essential picture of a planet in transition.
