Glaciers are huge, slowly moving frozen veins whose formation dates back hundreds and perhaps thousands of years. The seasonal melting of glaciers is a natural phenomenon, but it has been greatly accelerated by the effect of global warming.
The movement of the largest iceberg in the world, which is more than twice the size of the capital, London, has caused great concern among the scientific community and those concerned with the environment around the world after it began to move from its place as a result of melting, for the first time in more than thirty years, as the British newspaper “Daily Mail” reported. The giant iceberg, which is more than twice the size of the capital, London, is the largest ice block in the world, which has been stuck in the ocean for more than thirty years. It has finally begun to move. The area of the ice block is about 1,540 square miles and its thickness is 1,312 feet. The iceberg is currently moving northwards by ocean currents and winds at a rapid rate. After 30 years of stability on the ocean floor, this ice mass has begun to drift across the Antarctic Peninsula, which is supposed to collapse due to the harsh waters when it reaches the open ocean.
Unlike many large icebergs that have broken off from Antarctica and float far away, this one did not move except a few hundred miles when it broke off from the ice shelf due to its attachment or attachment to the bottom. However, it has been freed and is moving now and has begun to move. The movement of the mountain was discovered in 2020 by Dr. Andrew Fleming, a remote sensing expert at the British Antarctic Survey. It is expected that the iceberg will reach the Antarctic Ocean Stream, which is a 13,000-mile-long ring of ocean water flowing around Antarctica. It is possible The ice mass will stabilize again near South Georgia (an island located to the north of the South Atlantic)
If this happens, many marine organisms in that area will be affected. If the ice mass is stuck in an area, it will disrupt food sources for marine organisms. When melting, the minerals released from the ice can provide nutrients to organisms at the bottom of the ocean food chain. Frozen bodies of water reflect the excess heat carried by the sun's rays and send it back into space. If these bodies recede, temperatures will rise further. In addition, the melting of glaciers would increase the rise in sea levels, leading to coastal erosion.
The World Wide Fund for Nature explained that the melting of glaciers around the world has increased in 2021, and that more than a third of the remaining glaciers in the world will melt before the year 2100, even if humanity is able to reduce emissions resulting from burning fossil fuels. The cryosphere, such as glaciers, snow covers, ice sheets, and permafrost wherever they exist, is the largest natural reservoir of fresh water in the world. It is the source of rivers and fresh water supply for an estimated 1.9 billion people. Changes in cryospheric water resources will impact food security, human health, and ecosystem integrity and conservation, leading to significant impacts on economic and social development.
The parties participating in the Climate Summit (COP28) must take effective measures towards reducing emissions before the industrial revolution.
