Another strange phenomenon. This recently has come under the attention of U.S government scientists is that the Arctic ocean’s floating ice cover has shrunk to its second-lowest extent. According to satellite records which were made known in 1979. Until recently after nearly the last 42 years has earth’s frozen skull cap has been covered less than 4 million square kilometers. What does this mean? Is melting artic poses danger in other ways? or is contributing to something way more serious than what we’re led to believe? Read on more to know more bout the impacts the melting ice on the Arctic has over the environment.
What are the problems diminishing ice level poses?
Researchers observed in their studies that the sea ice has diminished to an alarming 14 % percent over the decade. And in 2035, there is a possibility that the Arctic will experience it’s first ice-free summer. But the melting of the ice levels in the Arctic doesn’t guarantee the boosting of sea levels than melted ice cubes overflow the glass of water. Which you might be wondering what does this have to do with it.
One thing’s for certain that it will lead to the extinction of polar bears. Which their numbers are dwindling and nearly going extinct. And leading to drastic changes in the region’s marine ecosystem affecting whales and phytoplankton. This leads it to a very crucial question as to how will it affect humanity? Turns out there’s more to it which we need to watch out for.
It creates a Feedback loop, according to geophysicist at Columbia University Earth Institute Marco Tedesco. “Sea ice removal creates dark ocean, which in turn creates a powerful feedback mechanism”. Freshly fallen snow bounces 80% of the sun’s radiative force back into space. Imagine if that snow is gone, oceans already absorb 90% of the excess heat generated by greenhouse gases. Which is already harming the planet at a greater pace with massive marine heatwaves, altered chemistry, and dying coral reefs.
