Antarctica turns greener as climate changes: Study
Antarctica is getting greener as a result of climate change, scientists said Thursday.
In a study published in the U.S. journal Current Biology, researchers reported that plant life on Antarctica, especially moss, is growing rapidly, in the last 50 years.
Plant life only exists on about 0.3 percent of Antarctica, but the new findings suggested "major changes in the biology and landscape of this iconic region" under future warming, according to the study.
"In short, we could see Antarctic greening to parallel well-established observations in the Arctic," Professor Dan Charman of the University of Exeter, who led the research project, said in a statement.
The Antarctic Peninsula is known to have been one of the most rapidly warming regions on Earth. Annual temperatures there have crept up about 0.5 degrees Celsius each decade since the 1950s.
The researchers realized they could learn a lot about how rising temperatures have affected the ecology of the Peninsula by studying core samples taken from moss banks, which are well preserved in Antarctica's cold conditions.
In the new study, they looked at five moss bank cores at three sites from an area spanning about 400 miles (644 kilometers).
Those sites include three Antarctic islands -- Elephant Island, Ardley Island, and Green Island -- where the deepest and oldest moss banks grow.
The scientists analyzed data for the last 150 years, and found clear evidence of "changepoints" -- points in time after which biological activity clearly increased -- in the past half century.
"Temperature increases over roughly the past half century on the Antarctic Peninsula have had a dramatic effect on moss banks growing in the region," said lead author 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 researchers said they'll continue to examine core records dating back over thousands of years to test how much climate change affected ecosystems before human activity started causing global warming.

Amendment of Education Act: A betrayal to capable candidates
Not all, but many of the temporary teachers who have been wishing to become permanent, no doubt, appointed on the basis of their political ideologies. They couldn't succeed in the examinations despite repeated attempts. They carried the bags of those parties during their teaching career.
The Doklam dilemma
Being a buffer state between the two giant neighbors, Nepal should conduct its foreign policy vis-à-vis China and India in a very sensitive manner. Nepal has always maintained that it would not allow its soil to be used against any neighbor. At the same time, Nepal should make sure that its own national interests are never compromised.

To dogs, with love
Many find talking about basic animal rights stupid when no basic rights of people are guaranteed. However, there are still few people who are aware how humane behavior has turned toward cruelty and indifference which can be vividly seen through the way street dogs and other animals are abused around us.
Unanswered questions on recent leftist alliance
Although they seem to be very much communist while in opposition, whether about the 'Indian semi-colonial status' in Nepal or American hegemony, this has never been evident while they actually come into power and rule Nepal.

What we need to learn from Thailand?
Thailand is a developing country. But it seemed like a developed country at first sight. It is hard to believe that Thailand is a developing country. There are big buildings, and clean and broad roads. The city is clean with no trace of pollution.
Traffic Police in Kathmandu
As busy and hassling as the traffic system in Kathmandu is, the Traffic Police here have to handle an equally strenuous job. Over 1,400 traffic officers in and around the Kathmandu Valley battle against the pestering traffic and air pollution each day.
