The problems of global warming are affecting the environment at an impressive pace. Because of this phenomenon, nature in many parts of the world may change dramatically in the near future.

One of the problems in this regard is the danger of melting of the age-old glaciers, particularly in Antarctica. One of the main factors is the impact of carbon dioxide, writes the SSPDaily.

At the same time, scientists note that no matter how much the world reduces carbon dioxide emissions in the future, most of the ice in Antarctica will still melt. Their assumption is based on the fact that this could change the place and way of life of people in the future.

After all, complete melting will take hundreds of years, slowly adding 1.8 meters to sea level. For their research, the scientists used computer modeling. In the end, they obtained a calculation of the future melting of the protective shelf ice.

The results were stunning, as they showed how the structure of the glaciers protruding above the Amundsen Sea in western Antarctica will change. The study was published in the journal Nature Climate Change.

Scientists have convincingly proved that even if future warming is limited to 1.5 degrees Celsius, the melting process is projected to be unstoppable. According to the research, the global temperature has already risen by 1.2 degrees since pre-industrial times.

Scientists warn that glaciers near the Amundsen Sea are at the greatest risk of melting. The study focused on this area, which is located on part of the West Antarctic Ice Sheet.

It is noted that the scientists were able to model four scenarios of possible developments at once. In the end, they managed to study the main component of water melting. It turned out that the main factor is the dependence on the concentration of carbon dioxide in the atmosphere.

Moreover, the results of the study will not be able to please with optimistic scenarios. After all, in any case, ocean warming was too strong for this part of the ice sheet to survive.

At the same time, the scientists note that the disappointing results of their research should not hinder the fight against dangerous trends in other parts of the world. After all, there are other vulnerable areas on the planet that can be positively affected by reducing CO2 emissions.
