Antarctica, May 20,2017-One of the coldest areas in the world is getting greener, and researchers say it’s because of global warming.

Researchers from the University of Exeter in England who first studied the increase of moss and microbes in the Antarctic Peninsula in 2013, now say the greening of the region is widespread.


“This gives us a much clearer idea of the scale over which these changes are occurring,” says lead author Matthew Amesbury of the University of Exeter.

“Previously, we had only identified such a response in a single location at the far south of the Antarctic Peninsula, but now we know that moss banks are responding to recent climate change across the whole of the Peninsula.”

The peninsula, researchers say, is one of the more rapidly warming area in the world, adding that temperatures have risen by about a half-degree Celsius each decade since the 1950s.

For their study, researchers looked at five more core samples from three areas of moss banks over 150 years old. The new samples included three Antarctic Islands off the peninsula.

The cores, researchers say, showed “increased biological activity” over the past 50 years as the peninsula warmed. Researchers say their findings show “fundamental and widespread change,” and that the change was “striking.”

The changes are likely to continue.

“Temperature increases over roughly the past half-century on the Antarctic Peninsula have had a dramatic effect on moss banks growing in the region, with rapid increases in growth rates and microbial activity,” says Dan Charman, who led the research. “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 next step for researchers is to look back even further in history to see how climate change affected the region before humans made an impact.

The findings appeared in Current Biology on May 18. (VOA)

EMI is known as equated monthly installments. It is a fixed payment made by the borrower each month to repay the loan amount. The EMI is divided into two loan components. One is the principal amount, and the second is the interest amount. Whether you are applying for a personal loan, business loan, home loan, car loan, or education loan, EMIs are easy to calculate using the EMI loan calculator.

Swastika, one of the sacred symbols used by many religions like Hinduism, Jainism, and Buddhism.

The symbol of Swastika is known to signify peace, prosperity, and good fortune in the religious cultures of Eurasia. In fact, this symbol is considered very significant in Hinduism, Buddhism, and Jainism. But, at the same time, it has become one of the most misunderstood religious symbols and has been globally banned in many countries.

The reason why the symbol of Swastika is banned in many countries is because of its association with Adolf Hitler's extreme political ideology, Nazism, as Swastika as its official symbol.

Since emerging into the public eye with a historic gold medal at the junior world championships in 2016, he has maintained a high level of performance

India celebrated a historic day on August 7, as 23-year-old Neeraj Chopra became the first Indian to win an Olympic gold medal in athletics. In the men's javelin throw event, he achieved his greatest triumph, throwing the javelin 87.58 meters on his second try.

Neeraj Chopra was born on December 24, 1997, in Khandra village in Haryana's Panipat district. He grew up in a Haryanavi family of farmers. He is the brother of two sisters. He graduated from Dayanand Anglo-Vedic College in Chandigarh and is now enrolled in Lovely Professional University in Jalandhar, Punjab, pursuing a Bachelor of Arts degree. Chopra was bullied due to his obesity as a kid, which prompted his father to enroll him in a nearby gym. He then joined a gym in Panipat, where Jaiveer Choudhary, a javelin thrower, noticed his potential and coached him. When the 13-year-old Chopra finished training under Jaiveer for a year, he was enrolled at the Tau Devi Lal Sports Complex in Panchkula, where he began training under coach Naseem Ahmed.
