Global warming is very close to becoming irreversible

It seems that the phenomenon of global warming, with all its consequences, is very close to the point where it will not be stopped or reduced, despite the efforts of mankind. Although estimates vary researchers at the details, the average global temperature will increase by about 6 degrees Celsius by 2100.
How gas emissions responsible for the greenhouse effect continues to grow instead of being stopped, scientists warn that our planet is close to reaching a limit point that global warming will be irreversible, and emphasized the melting polar caps and disappearance of tropical forests.
“For a decade we all are very sensitive if not try to fix the situation even last minute, I just went,” warns Will Steffen, executive director of the Department of Climatology of the Australian National University.
Despite alarming new reports, a new global climate treaty that would force large polluting countries like China and U.S. to adopt restrictive measures, will take place until 2015 and will take effect from 2020.
Point limit has been exceeded in the two ice caps at the poles, which act as huge “refrigerators” role to regulate global temperature. West Antarctic ice sheets has decreased continuously over the last decade, and ice sheets in Greenland annually lost about 200 cubic kilometers of ice since 1960.
Many climatology experts agreed that the Amazon rainforest will become more arid with continued warming of the planet. Approximately 1.6 billion tons of carbon have been lost in 2005 due to cutting of trees in tropical forests, the figure rising to values ​​of 2.2 billion tons in the year 2010.
One of the most serious concerns about irreversible global warming refers to the melting Siberian permafrost layer, which holds huge amounts of carbon in soil frozen carbon that, once released into Earth’s atmosphere would lead to incalculable consequences for the future of life on Earth .
In the worst case scenario, 30-40 billion tons of carbon per year may be issued so until 2040. By comparison, all vehicles in the world fossil fuel emit about 10 billion tons of carbon annually, which would add catităţile huge carbon will be released from Siberia.
