Record ice melt in Antarctica triggers flood warning on South Carolina coast (Image: Pixabay/Disclosure)
Melting ice in Antarctica could lead to a series of consequences, such as flooding on the Santa Catarina coast, due to rising sea levels and warming ocean water temperatures. According to the US National Snow and Ice Data Center (NSIDC, in English(), The sea ice surrounding Antarctica reached its lowest level in history during the winter, prompting a new warning to be issued on Monday (25) about the impact of climate change.

According to NSIDC, the ice sheets reached their peak on September 10, when they covered an area of 16.96 million square kilometers. This is the lowest winter maximum since satellite measurement began in 1979.
The cyclone causes winds of up to 100 kilometers per hour and waves up to 4 meters high in South Sudan.
According to the agency, there was a decline of about one million square kilometers less than the previous record set in 1986.
According to the professor of the Oceanography course at Unifali University, Mauro Michelina, the melting ice is a result of current climate changes. As a result, water is transported into the oceans, affecting coastal areas.
– It can cause a rise in sea levels, which is gradual and not immediate. Another very important effect, he explains, is that the water temperature will rise, which will cause the volume of water to increase and will also rise throughout the planet.

The latest forecasts, according to the expert, indicate that sea level will rise by up to half a meter within 50 years. However, the measure depends on the amount of greenhouse gases that residents will introduce into the atmosphere.
Melting ice can lead to storm surges and coastal erosion
There is another point that the expert pointed out, which is that the melting of ice may also be linked to flooding in areas that were not affected by the phenomenon, causing coastal erosion and destabilizing the composition of the beaches. He also warns that global warming is causing other harms, such as worsening the effects of alcohol.
— As a result, there are higher waves, which will occur more often and will be more intense. He points out that this will remove sand, which characterizes coastal erosion, which is a very serious problem.
Another concern highlighted by Michelina is marine biodiversity. This is because as sea levels rise and ocean temperatures rise, the behavior of plants and animals is also modified, which also harms the economic sector.

— Research conducted by a student here at the university demonstrated the change in the distribution of fish caught, affecting the economic and social sector. He says the effects of alcohol also have the effect that fishermen end up spending less time at sea, which prevents them from fishing and affects their income.
NSIDC researchers noted that the changes could affect the reproduction of penguins, which use sea ice to raise their chicks.
Professor Mauro Michelina claims that the only way to reduce density is to neutralize greenhouse gas emissions.
– Under current standards, the atmosphere will continue to warm, and as a result, the melting of ice in Antarctica will increase. This is very worrying because a more severe impact could lead to a complete deregulation of the Earth’s climate. The moment it affects the density of water, it interferes with the circulation of the entire oceans, and can be disastrous – that sums it up.
