Increasing Antarctic ice with global warming!

According to RCO News AgencyNASA’s satellite data shows that a sudden change in Antarctica has increased the volume of ice in the continent. Scientists, however, believe that this increase in ice volume is not a sign of the reversal of the global warming process and is a temporary abnormalities.

A new study shows that the Antarctic continent (Antarctica) has hosted more ice in recent years despite rising global average temperature and climate change.

Researchers at the University of Tongji in Shanghai have tracked changes in the volume of Antarctic ice for more than two decades using NASA satellite data. The overall trend shows a significant decline in ice on the continent, but from year 1 to 2, the Antarctica has re -regained some of its lost ice.

However, this is not a sign of the reversal of global warming and climate change. Imagine a large ski resort with a small jumping platform at the end. This is the image that shows the chart of changes in the volume of Antarctic ice. Although there has been an increase in the amount of ice recently, this is not even a start to compensate for the volume of ice for almost five years.

Much of this increase has occurred due to anomaly in the Rainfall in Antarctica. Rainfall has caused more ice formation. The surface of South Antarctic ice fluctuates annually, and this rise seems to have been slower since the end of the study period at the beginning of the year. The levels reported by NASA so far are similar to the level reported in year 2 and just before the sudden increase in the volume of ice.

According to the Antarctic and Southern Ocean Coalition, this frost, which covered the Antarctica, was the largest iceberg on Earth, larger than the entire United States and also accounted for 5 % of the world’s freshwater. The Antarctica is also surrounded by a sea or iceberg, which expands in the winter and retreats to the Antarctic coastline in the summer.

NASA’s satellite data have been monitoring this ice for years. It is important to study the changes in this ice, because any changes in these ice, including melting them, release water in the ocean, which is the main cause of sea level increase.

Satellite data shows that this ice has experienced a sustainable period of melting between the ages of 1 and 2. According to the study, the decline in ice in the second half of the period accelerated and with the increase in ice melting from the average ice reduction to about 2 billion tons in years 1 to 2 to about 2 billion tons in years 1 to 2. However, this trend has changed again.

The volume of ice in this area has increased from 1 to 2 years at a decrease rate of about 2 billion tonnes per year. Four refrigerators in the east of the Antarily, which saw a rapid decline in ice, experienced a significant increase in volume.

“This is not a strange issue,” says Tom Slater, an environmental science researcher at the University of Northumbia in the UK, who did not participate in this study. In warmer weather conditions, the atmosphere can keep more moisture. This increases the likelihood of heavy climates such as heavy snowfall that increased the recent volume of rainfall in eastern Antarctica.

One study showed an unprecedented increase in the volume of Antarctic ice between years 1 and 2, and it was found that high rainfall was responsible for increasing the volume of ice. The latest study also shows that this process continued at least until year 5.

Slater noted: Researchers think this ice increase is temporary. Almost all the melting of the Antarctic ice comes from the glaciers elsewhere that speeds up and flows into the ocean that is warming. This is still happening.

He added: While recent snowfall has temporarily made up for these ice, it has not yet stopped them. Therefore, this is not expected to be a long -term change in Antarctic behavior.

The world of warming up

Climate change does not mean that everywhere the earth is heated at the same speed. So a single area can never tell the whole story of our world warming.

Historically, the temperature has been relatively stable in most of the Antarctic areas, especially compared to the Arctic, which is four times faster than other parts of the Earth. Antarctic ice has been much more stable than the North Pole, but this has been changing in recent years.

In year 4, the Antarctic Ice Mercy reached its lowest level, and the researchers concluded that without climate change, such a phenomenon was very unlikely. At the same time, the iceberguard of the world is constantly approaching its lowest level. However, the world temperature is constantly getting closer to its highest level.

Countries in the International Treaty of the Paris Agreement have pledged to keep global warming preferably less than 0.5 degrees Celsius and be sure to keep less than two degrees Celsius. However, this study shows the first challenge. According to the Copernicus Cooperian Climate Change (Copernicus), it was April 21, the 21st month of 5 months, when the temperature crossed 0.5 degrees Celsius.

The study is published in the journal Science China Earth Sciences.
