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.
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.
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.
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.
A mother and child lost their lives in an avalanche on Tuesday while skiing at Pallastunturi in northwestern Finnish Lapland.
The Food Authority noted that it might be possible that foxes are more susceptible to avian flu infections than mink. However, the agency also suggested that infection prevention protocols may not have worked as well at fox farms compared to facilities that raise mink. The authority has now confirmed avian influenza cases at a total of 42 fur farms in Finland.
One spark was all it took. The driver of the forest harvester was working a logging site at Renko in Kanta-Häme. The grapple of the machine hit a stone, throwing a spark that set the underbrush ablaze.
Finland is experiencing warm and sunny weather with temperatures ranging between 20 and 25 degrees Celsius, and an advisory for strong ultraviolet radiation has been issued for the south and southwest.
The sale of fishing permits has been suspended for two sites where water temperatures have risen to critically high levels, especially for salmon.
Strong winds and heavy snowfall have led to flights being delayed, trains being cancelled, and motorists told to avoid unnecessary journeys.
There was a slight rise in population numbers of the very rare animals last year.
Harju said that due to its long tusks, she guessed that it was an older walrus, adding that the animal was calm during the hour that she watched it lay on the beach.
Meteorologists recorded a high temperature of 25.2 degrees Celsius (77 F) in the eastern town of Lappeenranta, marking the city's 40th 'hot' day this year, according to Yle forecaster Anne Borgström.
