Antarctica is turning green! Is a bad sign or good sign??



As we all know, there is a big Ice chunk on the bottom of the earth called “Antarctica” which is the most inhospitable region with −63 °C average temperature. But Antarctica will no longer to be Icey as it is.
The recent study has found a steady growth of moss in Antarctica over the last half a decade as temperatures increased which result of Global Warming. Plant life on Antarctica has been growing and spreading rapidly across the continent.
"Temperature rises over roughly the last 50 years on the Antarctic Peninsula have had a dramatic effect on moss banks growing in the region," said Dr. Matt Amesbury, of the University of Exeter. "If this continues, and with increasing amounts of ice-free land from continued glacier retreat, the Antarctic Peninsula will be a much greener place in the future”. The study says “the results suggest Antarctica’s ecosystems will alter rapidly under future warming, leading to major changes in the biology and landscape of this iconic region”.

But after reading this news, we come up with the question, Antarctica is turning green! Is a bad sign or good sign?
Green Antarctica as a good sign:
Research says, rapidly growing amount of moss on continent leads to complete change in the ecosystem from abiotic to biotic, which leads to a key change in future. Also, green Antarctica is good to decrease a temperature globally; if we consider all continents from Antarctica with full of moss and plant life on it rather than ice, decrease the chances of reflecting sunlight back to space and comes to our planet in terms of global warming.
In short, White continent reflecting sunlight in the air more than a green continent and vice versa. So green Antarctica will be great news in coming future to the overall planet environment as well as for Mother Nature.
Green Antarctica as a bad sign:
As a bad sign of green Antarctica; we consider all ice of Antarctica is melting and we all know the result that the level of sea water is going to increase. If all ice melted, global sea level increases by 60m. As per the research, in last 20 years, it has risen .13 inches per year. That’s twice as fast as the 80 years before. Even a small increase in sea level can be overwhelming. It became destructive erosion, flooding of wetlands, and impurity of soil and loss of habitat for many fish plants, birds. When large storms hit land, powerful storms will come to destroy everything in their path.

Millions of people of the world live in sensitive beachfront areas that will become more defenseless to flooding. Some low-lying islands will be completely underwater. It seems like bad news for beachfront cities, real estate market but not for Antarctica at this point.
