Antarctica’s rapidly melting ice has put scientists and ecologists around the world to sleep. The more advanced a country is in the fields of science and technology, the more it is at the forefront of these researches, analyzes and experiments. The United States, the United States, because it is at the forefront of these areas and as a world power has a wide range of interests around the world, it is deeply concerned about all kinds of developments and changes taking place in any region of the world. Keeps an eye on
As changes in the Antarctic ecosystem are likely to affect the entire world, US experts are keeping a close eye on them.
That’s why U.S. officials say their country is committed to tackling the challenge of climate change by providing funding for advanced scientific research and involving the international community in the results of that research. The research is just one example of this. A report by U.S. scientists prepared under the Pacific Laboratory of the National Oceanic and Atmospheric Administration (NOAA) It has been said that if the world works to reduce carbon dioxide emissions, the melting of the Arctic ice in the last decades of this century could be reduced.
According to an article published in Earth’s Future by the American Geophysical Union, the Arctic Ocean ice and glaciers have melted by 75% since the 1980’s. ۔ The declining sea ice at the top of the world is proof that the process of climate change, global warming, and rising sea levels has begun.
According to environmentalists, the melting rate of ice in the Western Antarctic has tripled in the last decade. As temperatures rise in the North Pole, more sea routes will open up in the region, creating more shipping facilities.
James Overland, of the National Oceanic and Atmospheric Administration’s Pacific Marine Ecological Laboratory, co-authored the article as co-author and co-author of the U.S. Maritime and Arctic Research Center, suggesting that By 2050, or in a decade or two, the Arctic will be almost completely free of sea ice.
According to experts, for various reasons, the tendency to increase the intensity in the North Pole is faster than in the middle latitude. One of the main reasons for this is the rate of magnitude that the earth’s surface reflects in the atmosphere. As more and more white and shiny ice melts, a darker ocean surface emerges from below, absorbing air from the ocean to the maximum instead of sending it back into space.
This means that as the speed of melting sea ice at the North Pole increases, this tendency will increase and the rate of melting of more ice will accelerate. But this new research shows that “if human civilization The mitigation scenario for “greenhouse gases” causes “average temperature forecasts for the North Pole by the end of the century. Can be reduced by 2 to 7 degrees Celsius.
Based on a review of the data, the authors of “Earth’s Future” estimate that major changes at the North Pole are linked to the climate system of the coming decades and that humans must be able to cope with these changes on a priority basis. According to him, one should consider adapting oneself. These authors predict with more certainty the short-term possibility of extreme trends in the North Pole.
However, he said that what could happen by the end of the century could not be predicted with such certainty. According to him, the highly complex process of forecasting weather patterns depends on “the nature of the turbulence of the world’s meteorological system” and other variables that, if measured in different ways, have significantly different results. It should be noted that measures to maintain current emissions rates and reduce emissions in comparison are among the variables being reviewed by the scientific team.
According to the results of Earth’s Future, there is a clear difference between the two pathways, leading to a significant difference in the temperature of the North Pole at the end of the 21st century, which is a strong indication of mitigation activities for the release of toxic gases.
According to environmentalists, temperatures across the Arctic will reach temperatures of 13 degrees Celsius in the autumn months and 5 degrees in late spring by the end of the century, based on meteorological forecasts based on normal gas emissions policy. The degree Celsius will increase, he said, adding that if the pattern is considered, which predicts a future in which gas emissions reduction policies have been implemented. In this case, there is a significant decrease of 7 and 3 degrees, respectively.
According to experts, the melting of sea ice at the North Pole makes it clear how the water in the dark part absorbs more and causes the process of increasing the intensity.
