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.
While the northeastern is recovering from the third major winter storm this month, the Arctic is experiencing one of the warmest winters on record.
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.
Fishermen fishing close to the shore in the Baltic Sea have seen a steady decline in herring and Baltic herring catches over many years. Large-scale trawling further out at sea could be one of the reasons behind it.
Which is worse: getting eaten, or drowning? Read on.
Hospital staff in protective gear are suffering as central Sweden experiences a heatwave.
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
Eva-Liv Island in the Franz Josef Land Archipelago has almost lost a peninsula. A 3-km-long strait has formed between the main land and the melted part where Cape Mesyatsev is located. Russian Arctic National Park employees discovered the missing land during an expedition to study walruses.
Drought conditions across Upcountry Maui have prompted the county to update its water shortage status for the unforeseeable future. Demand for water in the area currently exceeds supply by 20% — which moves its status from Stage 1 to Stage 2, county officials said Thursday.
About 20 to 30 medium-sized birds with black backs and white bellies were found spaced out along the entire beach of the island.
Around 60 ice seals have been reported dead across northern and western Alaska this month. The cause of the strandings and deaths is not known.
These windy conditions have started to negatively impact sea ice coverage in the Bering Strait. Based on satellite imagery and observations from residents across the region, more open water has started to appear along coastlines and thicker ice has been pushed around, climatologist Rick Thoman said. He noted that sea ice conditions are drastically different in the Bering Strait than they were five days ago.
A respiratory pathogen once thought to only affect sheep and goats has been found in Alaska caribou and moose. The bacterium, called mycoplasma ovipneumoniae, or "Movi," has also been implicated in the death of an emaciated caribou from the Fortymile herd last month.
Bird flu, or avian influenza, has struck the Swedish poultry industry hard this winter. Since November, thousands of turkeys and more than one million chickens have been culled. Malin Grant, an epidemiologist at the National Veterinary Institute, says the virus can be deadly for domestic poultry but the strains currently circulating don't easily infect or spread between people.
African swine fever is harmless to humans but deadly to pigs and wild boars. An outbreak in Serbia, Bosnia and Croatia this summer has led farmers there to cull thousands of animals.
