Despite the strong 2 "> C02 emissions and the drastic climate changes, we have not yet reached the point of no return and there is still time to save the polar bears, heavily threatened by the increase in temperature, the main cause of the melting of the glaciers.
This was revealed by the latest climate study published by the journal Nature, where the possibility of saving the natural habitat of polar bears.
The study is based on analyzes carried out in 2007, which show how the current rate of decrease in the volume of Arctic glaciers will not allow bears to live much longer; according to forecasts in fact only a third of the more than 22.000 polar bears (species defined as endangered by the IUCN, World Union for the Conservation of Nature) will be able to reach 2050. But there is still the possibility of avoiding this phenomenon, limiting the consequences, if all industrial countries really commit to cutting C02 emissions.
Scientists from the US Geological Survey, led by Steven Amstrup, came to this conclusion through the application of a climate model designed specifically for the Arctic area, which shows the possible consequences of a net cut in global greenhouse gas emissions.
"What we have found - said Amstrup - is that the point of no return has not yet been reached, and that in the presence of a decrease in gases the quantity of Arctic ice could reverse the current trend, which is a drastic decrease," and stabilize in the coming decades, thus saving the bears “.
“Our current research has highlighted that it is not too late to save polar bears from extinction - explained DeWeaver, atmospheric scientist - we have searched the hotspots of sea ice exposed to global warming, and we have not found any. In the end, therefore, the result will depend on how much greenhouse gas is released into the atmosphere in the future “.
