New research: Manker of Oxygen changes the largest mass massage of the earth in # 39; an oceans

While the recent report will be lost by the United Nations Intergovernmental Panel on Climate Change (IPCC) for precedent catastrophic species if we come to an increasing temperature of 1.5 ° C (2.7 ° F), the current situation is not in relation to the Permian Triassic Expression, the greatest event of their species in the history of ' the earth. Both 96% of all Navy species and 70% of earthly species are in that event created by the 252 million years ago. New research from the University of Washington and Stanford University has now shown why so many naval types were lost: Earning Early Earnings & # 39; metabolism – marine animals – that meant more oxygen – while the warm water did not have enough oxygen to survive.
In study, in & # 39; published on December 7th Science, researchers used a climate model with green hairdies that require the level to increase tropical ocean temperature temperature 10 ° C (20 ° F) higher than today's simulation performances at that time. The results show that the oceans like 80% of their oxygen are lost, with deeper water completely free oxygen. The scientists would model how these influences influence 61 modern navy types – from crustaceans and fish to corals and hooves – on the future that Permic animals & # 39; Tolerance for temperature and oxygen levels are compared by the comparable environmental conditions in which they were developed. The model found that high breeding species were almost completely drained, while many tropical species also extinct.
The increase in greenhouse gas in the late Permy is no different than the situation today. "Under a business-like ordinary emissions, after 2100 warmth in the top ocean marine will be 20 percent of the heat in the late Permy, and around the year 2300, it is between 35 and 50 percent , "said the first author Justin Penn, a University of Washington, a doctorate in oceanography. "This research marks the potential for a massage therapy that emerges from a similar mechanism under anthropogenic climate change."
