Scientists have long sounded the alarm about the problem of global warming. From the melting of glaciers, entire countries can go under water, and the consequences for all mankind will be catastrophic.
If the situation does not change, then, according to estimates, half of the 215 thousand existing glaciers may disappear. But that is not all. Recently, scientists have said that melting glaciers are likely to slow down the flow of water in the oceans. This will not only damage the stability of the ice shelves, but also disrupt the food chain for marine life. The details were told by Al Jazeera.
Recent studies show that in a few decades, that is, by 2050, deep-sea water flows in Antarctica can be reduced by an impressive figure – by 40%. And the consequences of humanity will be felt for centuries.
The changeover circulation of the waters of the World Ocean is very important, because it carries vital nutrients, carbon and oxygen. It is caused by the movement of denser water towards the ocean floor.
Matthew England, a scientist at the University of New South Wales, noted that if such predictions and computer simulations materialize (which is likely), “the trajectory along which the deep current will move will lead to collapse.”
Let’s take a look at a simple diagram. Water temperatures are rising and glaciers are melting. Fresh water from them ends up in the ocean. The salinity and density of the water is decreasing, as is the downward flow to the seabed.
According to John Church of the University of New South Wales, humanity must urgently reduce greenhouse emissions and take action to prevent a global catastrophe.
Slowing the flow of water will reduce the overall circulation and the amount of phytoplankton and nutrients rising from the ocean floor.
Earlier, GLOBAL HAPPENINGS said that scientists had discovered a new threat inside the Doomsday Glacier. A 130 km wide ice flow inside the glacier could expand significantly in the next 20 years.
