Two research teams from Japan and Australia, recently passed separate study drew a similar conclusion: if global greenhouse gas emissions is still not under control, we are currently experiencing, since 1997 global warming ” suspend “state is likely to be the last. After that, a sustained rise in global temperatures will lead to disastrous consequences. The first research team was led by scientists from Japan, consisting of several related papers published in “Nature Climate Change” magazine. Another research team was led by scientists from the University of New South Wales, Australia, who are the papers published in “Geophysical Research Letters” magazine.

Although the concentration of carbon dioxide in the atmosphere is increasing, but since 1997 the average global temperature has entered a plateau, and no obvious increase. Not only that, in recent years, many areas of the northern hemisphere has repeatedly appeared arctic weather. Therefore, it seems global warming seems to have entered a “pause” state, many scientists believe that the role of ocean heat storage is the main cause of this phenomena. The deep ocean to absorb heat slowed the rate of global surface temperature rises, enhanced the Pacific trade winds and sub-tropical circulation of heat will be transported to the surface of the deep Pacific Ocean, slowing the rate of increase in sea surface temperature. In addition, ground volcanic eruptions also to some extent slowed down the process. But with the end of the ocean endothermic effect, the global temperature will continue to rise.

Japanese research team used climate records and computer climate models of the world’s major regional climate data over the past 30 years were studied. The results showed that we are now experiencing global warming “pause” state, the possibility of subsequent re-emergence will be getting lower and lower. Specifically, their model shows that in the 1980s the natural movement of the atmosphere to slow global warming but also play a role in 50 percent; and turn of the century in the early 1990s, 10 years, this ratio has declined from 38% to 27%. They predict future impacts of human activities on global warming will be more significant, nature sound regulatory mechanism will gradually fail earlier.

Another Australian research team, through the 31 environmental model study concluded: if greenhouse gases continue at the current rate but also emissions, the possibility of another suspension period is close to zero in the global warming trend. Worse, they believe that the world’s oceans since the previous endothermic effect of storing a large amount of additional heat, which will be released to further accelerate the global warming process.

Physicist organizational networks reported on September 3, said the study’s two research groups show that global warming in a not too distant future will continue, and have disastrous consequences, and if we can reduce greenhouse gas emissions, it is still possible that adverse avoided. But no matter what, for the purposes of the Earth this really is the last chance.
