Here's how Antarctica is causing global climate change and rise in sea level
New Delhi : In an attempt to study the global climate change, scientists, for over 200 years, are working hard to find new organisms and data that could reveal Earth's climate history and signs of a climate changes.
But, Antarctica is not known for human population. Therefore, the United States and other 11 countries signed the Antarctic treaty in 1959 to ban military activities and invest into scientific investigations. Now, more than 40 other countries have joined the agreement since then, and the research station on the continent has grown rapidly.
Recently, the data collected by NASA shows that Antarctic has been losing more than a hundred cubic kilometres of ice every year since 2002. The Grace satellite confirms that the region is losing ice at an accelerated rate.
The ice loss rate has tripled since 2012 and has resulted in the increase of global sea levels by 0.12 inch (3 millimetres).
The team looked at the mass balance of the Antarctic ice sheet from 1992 to 2017 and found that the global sea level raised by 0.3 inches (7.6 millimetres).
These increasing rates of ice melting from Antarctica is causing sea level rise faster than any time in past 25 years.
Before 2012, the ice loss was at a steady rate of about 83.8 billion tons per year, contributing about 0.008 inches to the sea level rise every year.
Scientist in 2013, released 20 balloons into the air under mission BARREL to study Radiation-belt Relativity Electron Losses, led by physicist Robyn Millan of Dartmouth College in Hanover.
Experts launched a balloon every day or two into the circumpolar winds that circulate around the pole. Interestingly, the balloon floated anywhere from three to forty days, measuring X-rays produced by fast-moving electrons high up in the atmosphere.
The final balloon was released by the researchers on August 30, 2016, to study how electrons precipitate into earth's atmosphere.
A total of eight payloads were launched. The team was able to observe parts of near-Earth space at the same time as other important NASA missions.
