The horrifying effects of Global Warming have started coming on to the surface. The new research has indicated that the melting of the Antarctic glaciers due to global warming are pouring fresh water into the oceans around them. This freshening of the ocean’s water is blocking a process in which salty and cold water sinks below the sea surface in winter. This whole process results in the formation of the densest water on the Earth. This research has been conducted by Alessandro Silvano – a researcher from the University of Tasmania.
Two years back, one of the leading researchers James Hansen has also suggested that gigantic pulses of fresh water from melting glaciers could upend the circulation of the oceans. This may eventually lead to fast rising in the sea levels and even results in superstorms. The new research appears to have confirmed this research.
The researcher further explains the whole process. It further suggests that when cold surface water doesn’t sink deep into the ocean, a deeper layer of warm ocean current can travel and reach the bases of glaciers. This warm ocean current retains its heat because of the above cold water. This warm water currents result in the rapid melting of the glaciers along with the large floating ice shelves. Technically, the melting of Antarctica’s glaciers further triggering a “feedback” loop, which eventually results in more melting. The trapping of the cold fresh water and setting of the warmer water beneath it, creates more melting, eventually rising seas. Silvano further said that the research is not only modeling but it is something which is actually happening in the real ocean. Further claimed that it is the first time that they get the actual evidence of this mechanism.
In a recently published article, another oceanographer Matthew Long supports the research saying that the research is a consistent and large body of existing literature are supporting the warming and freshening of the deep ocean in the southern hemisphere. Long further said that this study can be considered as an evidence suggesting that the world’s oceans are changing and this change is taking place at an accelerated pace.
Pointing out concern, lead author Silvano said that apart from melting by the ocean, Antarctica could also start melting as a result of global warming. As a result, more meltwater forming in the ocean. Due to the feedback between the ocean and the glaciers, the problem of rising sea levels would remain the same.
