Another crisis is before the world. This is the result of tampering with nature i.e. climate change. An iceberg of about four thousand square kilometres, three times the size of Delhi, three and a half times the size of New York City and two and a half times the size of Greater London, has drifted out to sea from Antarctica. This has happened for the first time in 37 years. Environmental scientists are worried about its movement.
Environmentalists are seeing this change as a major threat to marine life, ships, small islands, etc. This glacier has separated from Antarctica. Its area is more than four thousand square kilometers. It broke off from Antarctica in 1986 but remained stable. Now, after 37 years, it has started to leave its place and sink into the Weddell Sea in Antarctica.
Accelerated speed
It is exposed to scientists as an island of ice. As it is melting, its size is also decreasing and its speed in the ocean is also increasing. European scientists have seen and felt it for the first time. Scientists have also warned the world through satellite images. Science is seeing this as a threat. It is currently moving south past the northern tip of the Antarctic Peninsula.

…So what will end up being Georgia Island?
According to international media, this iceberg named A23A was sliding for the last one year but now its speed has increased and it is a matter of concern. Because of its small size, sea breezes are now able to push it. It has risen above sea level. Scientists believe that as it gets smaller, it may diverge.
It may sink into the ocean by the time it reaches Georgia Island. If not, it can destroy this island too. There may be danger from wild animals etc. May also move to South Africa. Then its distance will increase and it can become a threat to aircraft. However, its size is sure to decrease every day but still it can pose a threat to marine life.
Finding opportunity in disaster
When it seceded in 1986, the Soviet Union’s research center was located on this part. Amid growing unrest, Russia has also sent a team to rescue its research center and protect its equipment. Scientists say that despite its separation in the year 1986, it was stable, but in the year 2020, for the first time, movement was seen in it and now it has increased.
This is a warning that we must be careful. There should be work on the environment all over the world. Otherwise, other adverse results may be observed. Scientists are also believing that after this iceberg breaks and slides, something new can be found under it. The attention of the world should go to this side as well.
Scientists say sea levels have risen nine inches since 1880. Of these, about a quarter is contributed by the breakup and melting of ice sheets.
The world’s largest iceberg is on the move for the first time in more than three decades. At almost 4,000 square kilometers, the Antarctic iceberg called A23a is roughly three times the size of New York City https://t.co/MD2UKvnN1k pic.twitter.com/cEd6o3jqXe

What do Indian scientists say?
Indian meteorologist Dr. Anand Sharma says that icebergs have been breaking up in Antarctica before. This is a natural process. Many countries of the world are researching there. The movement of people is increasing. Many rich people, in their desire for ultra pure water, order and bring icebergs from there. Not only can climate change have an impact, human intervention has also increased exponentially. The special thing about this iceberg is that its size is quite large. Certainly this can be a cause for concern.
It remains to be seen what negative impact this will have on our lives in the future. The good thing in this context is that the ocean water is warming. Thus this iceberg will get smaller every day. Dr. Sharma says that the breaking up of such a large iceberg can definitely be an effect of global warming but it can also bring new opportunities for us. All the countries including India are exploring there, all the focus is on what is under this land of ice? What is oil, what is mineral? Breaking it down and moving away can also make searching easier. It will be interesting to see.
