For years, researchers thought an infectious pathogen was behind sea star wasting disease. A new study found that multiple species of bacteria deplete oxygen from the water effectively suffocating sea stars. These microbes thrive when there are high levels of organic matter in warm water and create the low oxygen conditions.
The risk associated with any climate change impact reflects intensity of natural hazard and level of human vulnerability. Previous work has shown that a wet-bulb temperature of 35°C can be considered an upper limit on human survivability. On the basis of an ensemble of high-resolution climate change simulations, we project that extremes of wet-bulb temperature in South Asia are likely to approach and, in a few locations, exceed this critical threshold by the late 21st century under the business-as-usual scenario of future greenhouse gas emissions. The most intense hazard from extreme future heat waves is concentrated around densely populated agricultural regions of the Ganges and Indus river basins. Climate change, without mitigation, presents a serious and unique risk in South Asia, a region inhabited by about one-fifth of the global human population, due to an unprecedented combination of severe natural hazard and acute vulnerability.
Orca whales appear to be killing great white sharks and eating their livers and, in some cases, their hearts.
As climate change opens new regions to mosquitoes, Nepal suffers an outbreak of the painful viral disease that has sickened more than 9,000 people.
Which is worse: getting eaten, or drowning? Read on.
Belugas and narwhals can apparently breed. Scientists have confirmed the only known specimen of beluga-narwhal hybrid.
Quriyat, Oman just blasted past a 24-hour minimum-temperature record, beating the previous "highest low," which was also set in Oman.
Scientists scramble to explain unusual bloom of Sargassum
That's right, California sea lions. As populations of native Steller sea lions decline, Maniscalco says a growing number of California sea lions are showing up on Steller sea lion rookeries and haul-outs across the state. According to his research, some 33 sightings have been recorded. And some of those California sea lions have made their way as far west as the Pribilof Islands in the Bering Sea.
The precipitation, although lasting just a few days, was good news for dams supplying water to more than 15 million people in the city. Just a few weeks after a drought alert, dams have seen a rise in their water levels.
The last time it was this cold was in 1916, with a low temperature of -0.6°C.”
The Hatcher Pass Road in Alaska has opened for the summer season, but deep snow remains at higher elevations, with crews spending the last week digging out the road over the pass before opening it.
There were 305,000, 10 lb Atlantic salmon when the pen at the fish farm in the San Juan Islands burst open on Saturday.
Forecasters say they are expecting significant coastal erosion from Utqiagvik to Unalakleet from the second severe-weather event to hit the region in three weeks.
Two villages along the Lower Yukon River have begun evacuating their most vulnerable residents from a tundra fire.The fire late Thursday was burning less than eight miles from St Mary’s and nearby Pitkas Point, and wind continues spreading the flames closer to the villages with a combined population of over 700 people. Yute Commuter Service is sending all its planes to St. Mary’s to evacuate residents, and Grant Aviation is prepared to assist.
The collapse last week of an ice shelf the size of New York City was the first time scientists have ever seen an ice shelf collapse in this cold area of Antarctica.
The low temperature in Vancouver hit a chilling 1.6°C, breaking an all-time low that's stood in place since 1937 when temperature gauges hit 2.8°C.
