Fear of the birth of global warming ocean fish such as dead zones difficult to survive

Research report released today shows that global warming may be causing in the marine "Dead Zones", which fish and other seafood are difficult to survive, but will continue as long as 2000 years. 
The study's author said that the world must cut carbon emissions to curb this trend, because it may be disrupting the marine ecological system, so that future generations can not obtain food from the oceans. 

According to the "natural earth sciences (Nature Geoscience)" Journal published on the Internet report, the Danish scientists established a computer model to simulate the next 10 million years of climate change in the situation. 

This mode is the core of two-to-use program, the use of carbon dioxide in the atmosphere for the temperature indicators. Carbon dioxide is the main cause of global warming gases. 

Based on the situation of the worst program in 2100, when atmospheric carbon dioxide concentrations will reach 1168ppm, which is about three times today's concentration. If the basis for a more optimistic pattern, then in 2100 when the concentration of carbon dioxide will be 549ppm, which is more than today's concentrations increased by about 50%. 

Relevant factors into consideration, scientists predict the worst case, the temperature may be higher than before the industrial age 5-7 degrees Celsius, and if the situation better, then the temperature will rise 2-4 degrees Celsius. 

Denmark University of Science and Technology (Technical University ofDenmark) physicist Speed Health (Jens Olaf PepkePedersen) said that no matter what kind of situation, on the marine are bad news. 

If the worst case, the ocean temperature increases, the current slowdown will lead to lower oxygen content of the oceans, resulting in the so-called "death zone", fish and shellfish and other higher forms of marine life can not survive, and may in 1500-2000 years are unable to restore.
