Antarctica seriously degrades biodiversity when sea water heats up

As long as the Antarctic seawater rises to 1 to 2 degrees Celsius, the biodiversity of this sea will be severely reduced, according to a study published Sept. 1.

Scientists from the British Antarctic Discovery program and the Smithsonian Environmental Research Center have conducted experiments by placing seabed heating panels in the Antarctic region to measure the impact of the change. climate with local marine species.

Although it only warms the surface water, this increase in temperature has caused "tremendous impacts on biodiversity " , the scientists concluded.

This increase in temperature has caused "tremendous impacts on biodiversity".

Marine biologist Jonny Stark told Xinhua that the findings were "surprising". During the observation period of up to 9 months, this study shows how large the impact of climate change can be on some regions of the world.

For example, in Australia the temperature of the sea often varies from 10 to 20 degrees Celsius for a year, making the organisms well adapted to temperature changes. But in Antarctica the temperature of the sea here is almost unchanged.

"It's certainly a concern, I don't think anyone wants to change just a few degrees and the environment changes so much, " Stark said.

The study also showed that the number of species will disappear because of changing habitats, but some special species grow and proliferate. Two types of pests with scientific names, Romanchella perrieri and Fenestrulina rugula, have increased the number of individuals up to 70% in the area of ​​the research scientists.
