Hotter seas threaten marine wildlife with extinction, researchers warn

LONDON: Polar bears and different iconic animals might be extinct via the end of the century if ocean temperatures continue to upward push on the present rate, marine biologists warned on Monday.

Warming temperatures brought about via climate changing emissions might result in a catastrophic lack of marine wildlife and drastic adjustments to ocean food webs via 2100, scientists on the Florida Institute of Technology and the University of North Carolina stated in a paper printed in the journal 'Nature Climate Change'.

Much present marine life won't be able to tolerate ocean temperatures which might be projected to increase via 2.8 levels celsius on reasonable, according to the study.

"With warming of this magnitude, we expect to lose many, if not most, animal species from marine protected areas by the turn of the century," stated the study's lead author, John Bruno, a biologist on the University of North Carolina-Chapel Hill.

Marine safe spaces, established as sanctuaries for polar bears, coral reefs and different wildlife threatened via human activities equivalent to fishing and oil extraction, have failed to offer protection to species from the affects of worldwide warming, the scientists stated.

In Florida Keys National Marine Sanctuary, a large number of corals already have been destroyed via bleaching and illnesses related to higher temperatures, the study famous.

The protections in position can be ineffective via 2100 if greenhouse fuel emissions continue to upward push on the present rate, researchers stated.

Reduced oxygen concentrations in the ocean - one end result of worldwide warming - will make marine safe spaces uninhabitable to most species, they argued.

Richard Aronson, a co-author of the study and head of the dep. of ocean engineering and marine sciences at Florida Tech, instructed the Thomson Reuters Foundation that wildlife in the Arctic and Antarctic is particularly at risk.


"Oceanic warming is happening most rapidly at the poles. Warming will threaten polar ecosystems generally, including iconic wildlife like polar bears and penguins," he stated in an e mail.


Around 90 in keeping with cent of the heat trapped via greenhouse gases is absorbed via oceans, Aronson stated.


"We have to take bold steps individually and as a society to control emissions. Shifting away from our dependence on fossil fuels would be a major step in the right direction," he stated.


"Stabilising emissions over the next few decades could cut the rate of warming in half," he added.
