STATES CHRONICLE – A new study has been conducted by NASA, which shows that the Antarctica ice sheets are not melting, but gaining snow.
There is a snow accumulation in the arctic region, which began some 10 000 years ago and which is now adding enough snow to make up for whatever mass the glaciers are losing via global warming and, thus, via melting.
Of course, the study in itself and its results are highly controversial, as they come against everything we have come to know about that part of the globe in the past years. It has become general knowledge that the ice caps are melting, sea levels are rising and the waters, as well as the climate itself are getting warmer. And now this study comes forth to say that the ice sheet is actually gaining snow, not losing it.
The study states it has used data received from satellites, which show that the Antarctic sheet has gained an average of 112 billion tons of ice each year between 1992 and 2001. Indeed, according to the global warming theory, it did decrease between 2003 and 2008, from the reported 112 billion to 82 billion tons each year.
The lead author of the study, Jay Zwally, a glaciologist with the NASA Goddard Space Flight Center says he and his team do indeed agree with the classic studies on melting glaciers at the poles, but only concerning the Antarctic Peninsula and the Thwaites and Pine Island region of West Antarctica.
They do not, however, agree with the classical studies and theories when it comes to East Antarctica and the interior of West Antarctica. Here, they say, ice gains are superseding the losses in other areas.
Even so, if this seems like good news, it’s only good news for now, Zwally, warns us. In just a matter of decades, this might very well change and the ice sheet variations to reverse. The losses in the Antarctic Peninsula and in the West of the Antarctic, in just the space of 20 or 30 years, might increase so much that the snow gain in the other parts mentioned might not be enough to compensate anymore.
The whole process of gaining snow began 10 000 years ago, at the end of the last Ice Age, when the weather became warmer and more humidity was carried over the continent, doubling the quantity of snow that fell on the ice sheet. That snow has been accumulating over the past thousands of years, slowly turning into ice and thickening the ice sheets.
