8,000 Strange Blue Lakes Appear In Antarctic, Threaten Our Existence




We all know that Greenland and Antarctic are in serious trouble due to man-made global warming. What we all don’t know is the magnitude of their troubles, which have far-reaching consequences — for us.

A satellite-based study published in July revealed that Greenland’s ice sheet lost about 90 billion tons a year last century, but this century the average has reached about 269 billion tons a year. The Greenland ice sheet lost a whopping 1 trillion tons of ice between 2011 and 2014 alone; and a big portion of it, found the study, came from just five glaciers.

According to GIZMODO, these lakes are a sign of global warming and a cause of ice sheet collapse: as meltwater from the lakes drains into the underlying ice, it can lubricate the ice sheet’s foundation, causing it to weaken and causing it to eventually break apart.

This is the same process that apparently melted Greenland’s glaciers and resulted in unprecedented loss of 1 trillion tons of ice; scientists are worried now that the worrisome trend has been observed in Antarctica — part of the Earth that largely resisted climate change until now.



Stewart Jamieson, a glaciologist at UK’s Durham University and one of the study’s authors, told The Washington Post:

 “That’s the part of the continent where people have for quite a long time assumed that it’s relatively stable, there’s not a huge amount of change, it’s very, very cold, and so, it’s only very recently that the first supraglacial lakes, on top of the ice, were identified. 

“What we find is that the appearance of these lakes, unsurprisingly, is correlated directly with the air temperature in the region, and so the maximum number of lakes, and the total area of the lakes, as well as the depth of the lakes, all of these things peak when the air temperatures peak.

“The size of the lakes are probably not big enough to do much at present, but if climate warming continues in the future, we can only expect the size and number of these lakes to increase… It’s not hitting the glacier really hard at the moment, this process, but of course, as things warm up, we’d expect it to start doing more damage, like we see in Greenland.”
