The Arctic region has warmed four times faster than the rest of the planet, scientists have reported. Litzow called what’s happening in the Bering Sea a “bellwether” of what’s to come.
About 10 billion snow crabs disappeared from the Bering Sea between 2018 and 2021. Now we know the sad reason why. ... typically live in water temperatures no more than 2°C, they can easily ...
October 20, 2023 at 3:04 AM. Billions of snow crabs have disappeared from the ocean around Alaska in recent years, and scientists now say they know why: Warmer ocean temperatures likely caused ...
If sea temperatures continue to rise, then some fauna may move to cooler water and some range-edge species may disappear from regional waters or experience a reduced global range. [115] Change in the abundance of some species will alter the food resources available to marine mammals, which then results in marine mammals' biogeographic shifts.
Habitat destruction. Map of the world's biodiversity hot spots, all of which are heavily threatened by habitat loss and degradation. Habitat destruction (also termed habitat loss and habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or ...
A leopard seal (Hydrurga leptonyx) Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), sea otters and polar bears. They are an informal group, unified only ...
The IPCC (2019) says marine organisms are being affected globally by ocean warming with direct impacts on human communities, fisheries, and food production. [67] It is likely there will be a 15% decrease in the number of marine animals and a decrease of 21% to 24% in fisheries catches by the end of the 21st century because of climate change. [68]
Scientists have identified several new marine species in a pristine underwater ecosystem recently discovered in international waters -- and they expect to find more. Modern technology that allows ...
