Comparing the world before and after the corona 19 became popular worldwide, it is inevitable. Experts say that even if a preventive vaccine or remedy comes out and Corona 19 is conquered, it will not be possible to return to the same society as before. The recovery of the stagnant economy caused by Corona19 is also an immediate challenge, but in fact, a bigger disaster is behind it. That is the climate change caused by global warming that we have forgotten for a while. Although the Earth seemed to be revived temporarily thanks to the Corona 19 countermeasures, such as social distance and movement restrictions, studies have been published that the global warming continues at this moment.
● Sea is more threatening to survive than land
University of Queensland Australia, Institute of Marine, Atmospheric and Biological Sciences, Federal Science Industry Research Institute, Sunshine Coast University, Nelson Mandela University, South Africa Ecological Protection Research Center, Hokkaido University of Japan, British Marine Science Research Society of Scotland, Albert Ludwig University of Germany, Helmholtz Marine Science Research Center On the 27th, a joint research team from the Philippine International Rice Research Institute announced on the 27th that the oceans are more affected by global warming than land, and that the survival of marine life is under serious threat. The results of this study were published on the 26th of May in the international journal of climate science, Nature Climate Change.The research team analyzed the global warming rate of land and sea for 50 years from 1955 to 2005, and the global warming scenario according to greenhouse gas emissions. Poorly predicted the rate of global warming between 2050 and 2100.
● Deep sea temperature rises 2 to 4 times faster
As a result, it was confirmed that seas with a temperature lower than that of land and sea level, but deeper than 1000m, are 2 to 4 times faster than the average global temperature rise rate in the second half of the 20th century, depending on the region. If greenhouse gases continue to be released at the current rate, the team predicted that the rate of temperature rise in the deep sea at the end of this century would be faster. The team also analyzed the ecological space occupancy patterns of 20,000 marine organisms to understand the degree of threat to biodiversity brought about by the rate of ocean climate change. Below the central sea, there are plankton, krill, and squid, which are the lowest part of the ocean food chain, and climate change threatens their survival, shaking the entire marine ecosystem and affecting fisheries.
● Move high-level marine life… Up to 6 times faster
Biologists, oceanologists, and climatologists from Picardie de Verne, France, Toulouse Paul Sabatie, Montpellier, Seattle University, Tennessee, and the United States are also unpredictable. It has been pessimistic. The results of this study were published in the May 26 issue of the journal Nature Ecology and Evolution.
The research team compared and analyzed the changes in distribution and trends in global warming from 1870 to 2018, targeting over 13,570 species of animals and plants on land and on the sea. As a result, according to the climate change caused by global warming, animals and plants are gradually moving to high-latitude regions, and especially marine species are moving up to 6 times faster than terrestrial species.
"The movement of species due to global warming may be accelerated or slowed by human activities such as fisheries, agriculture, and various urban planning," said Gael Grunoe Toulouse Paul Sabattier University professor. "The species seem to prefer the way they move their homes, rather than adapting to their current environment."
