A Large Iceberg is About to Break Away from Antarctica

Scientists from Swansea University in Wales announced on Thursday, June 1, that a massive iceberg, the size of the state of Delaware, is on the verge of breaking away from Antarctica and, if it does, it will become the largest floating iceberg in the world. According to Agence France-Presse, on the very day that Donald Trump, the President of the United States, is set to announce his decision on whether to remain in or withdraw from the Paris Climate Agreement, satellite images show that a huge mass of ice, covering an area of 5,000 square kilometers, is about to detach from the continent due to rising temperatures in Antarctica. Swansea University stated, "The formation of this deep crack in the Larsen C ice shelf located in the northern part of Antarctica will lead to the separation of the largest iceberg ever recorded." This crack in the Antarctic ice shelf has increased by about 17 kilometers in just six days, and the iceberg in question is now only connected to the main ice layers by a length of 13 kilometers. This iceberg resembles a human finger and is approximately 350 meters thick. In another part of the statement from Swansea University, whose researchers first detected and reported this incident, it is mentioned: "The time for this massive iceberg to separate is likely very close. It seems that not much is left to prevent this iceberg from breaking away from the other ice layers." The Larsen C ice shelf is the northernmost ice shelf outside of land in Antarctica and is also the largest ice mass on the continent. If this iceberg breaks away, the area and volume of the Larsen C ice shelf will decrease by 10%, reducing it to its smallest size on record. Agence France-Presse quotes researchers as saying that the release of this iceberg alone will not lead to a rise in sea levels. However, its separation could destabilize the Larsen C ice shelf and potentially lead to its complete disintegration, which would add a massive volume of water to the oceans. Researchers say that if all the water frozen in the Larsen C ice shelf were to melt into the ocean, global sea levels would rise by about 10 centimeters. They state that the total ice layers in the western part of Antarctica contain a volume of frozen water that could easily raise sea levels by six meters. In the past, two massive ice layers in the eastern part of Antarctica have disintegrated. The first, known as Larsen A, occurred in 1995, and the second, known as Larsen B, with an area of 3,250 square kilometers, broke away in 2002. According to researchers, the Larsen B event has been unprecedented in the last 12,000 years since the last ice age on Earth. Researchers from Swansea University state: "It is almost universally accepted that the increase in ocean and atmospheric temperatures is the main factor behind the disintegration of ice layers everywhere, including Antarctica." They added: "Antarctica is one of the regions that is warming at a faster rate, a factor that has undoubtedly contributed to the deep crack in the ice layers and the possibility of the discussed iceberg breaking away." Ice layers naturally crack and separate, and although it has not yet been scientifically proven, it seems that global warming is not without its impact on accelerating this process. Many countries around the world have signed the Paris Climate Agreement, committing to take necessary actions to keep global warming below two degrees Celsius above pre-industrial levels. The Earth's temperature has increased by about 1.1 degrees since that time. During his election campaign, Donald Trump promised to "terminate" the Paris Agreement, and in recent days, he has stated that he will announce his final decision on this matter on Thursday.
