Science and Technology Daily, Beijing, August 26 (Reporter Zhang Mengran) A climate study published on the 26th in the journal "Science Reports" under Natural Science Research pointed out that depending on the greenhouse gas emissions in the first half of the 21st century, there may be 35.
6% to 95.
% Of the sea surface climate in the 20th century will disappear by 2100.
The sea surface climate here is defined by the surface water temperature, pH value, and mineral aragonite concentration
.
The research results also show that 10.
The research team including Katy Rothhorse, a researcher at Northeastern University’s Marine Science Center, simulated the global ocean climate in three periods: the early 19th century (1795-1834) and the late 20th century (1965) Year-2004), late 21st century (2065-2104)
.
In order to assess the future climate, the fifth assessment report of the United Nations Intergovernmental Panel on Climate Change adopted four greenhouse gas concentration scenarios, ranked RCP2.
The research team derived from the comparison which ocean climates in the 19th and 20th centuries may disappear in the 21st century, and which climates that did not exist in the 18th and 20th centuries will appear in the 21st century (new climate)
.
Their research shows that although the ocean climate has not changed significantly in the 19th and 20th centuries, by 2100 there may be 10% to 82% of the ocean surface with higher temperatures, more acidic pH, and lower aragonite saturation.
Researchers believe that although some marine species are currently adapting to the changing ocean climate by spreading to new habitats, if the current ocean climate disappears, such adaptation may no longer be possible, and those species that cannot quickly adapt to the new climate Will also disappear
