Due to climate change, five cities in South America may be under water by 2100

Global warming has Sea level rise About 20 cm since 1880, and the rate of increase is increasingly accelerating.

In this sense, A Last post From the magazine The nature of climate change “According to the 2021 report of the Intergovernmental Panel on Climate Change, global average sea level is expected to rise between 0.28 and 1.01 meters by 2100,” he warned.

“The consequences of sea level rise include a Increased risk of floodingAnd sudden changes in river courses, and Displacement of coastal residents“, the researchers analyzed in the publication.

When it came to explaining the cause of this event, they specified: “Anthropogenic climate change is driving sea level rise through thermal expansion of seawater and the melting of glaciers and ice sheets in Greenland and Antarctica.”

Work published jointly with the organization Central climateThis was announced, and it is dedicated to analyzing climate changes in different places on the planet Many beaches in the world could disappear. Many South Americans appear on the list.

according to National Office of Oceanic and Atmospheric Administration (NOAA) In the United States, the imminent risk of flooding that many coastal cities in Latin America face as a result of sea level rise is a product of climate change and mismanagement of water resources, including oceans, seas, and lakes, as well as groundwater extraction.

Thus, the study indicates that it is among the most affected cities in La Reina America Barranquillain Colombia, followed by other important cities such as Maracaibo in venezuela, Rio de Janeiro And Porto Alegre In Brazil, and Punta del Este In Uruguay.

This situation also places parts of the province Between rivers And based on Buenos Aires In Argentina, according to the publication.

In particular, Barranquilla is in a vulnerable location due to its geographical environment close to the mouth of the Magdalena River, which facilitates persistent flooding in the area. For their part, Maracaibo, Rio de Janeiro and Porto Alegre face similar risks due to their direct proximity to large bodies of water.

The National Oceanic and Atmospheric Administration (NOAA), through its investigations, urged affected countries to embrace this idea. Immediate preventive measures. According to the organization, these measures should be directed, not only at the government and business sector levels, but also at the community level, to raise awareness about the environmental impact that contributes to exacerbating this problem.

Previous forecasts of World Meteorological Organization The World Meteorological Organization has warned that the problem of rising sea levels increases the risk of one in ten people being forced to move due to advancing water in coastal areas, according to the expectations of two recent scientific studies.

This, according to the latest work, will not only affect these five countries south americaBut similar situations can also arise in countries such as Mexico, Honduras and Nicaragua, The water level may reach 2.1 meters above current levels.

What happens, according to experts, is that about 90% of the excess energy that accumulates on Earth due to increasing concentrations of greenhouse gases ends up in the oceans and seas. As the water temperature increases, the volume increases. the Thermal expansionlike him Melting Ice sheets and glaciers in Greenland and Antarctica around the world are causing sea levels to rise.

Although this increase is occurring at the global level, expectations indicate that… sea ​​level In Latin America and the Caribbean it is growing at a rate higher than the world average.

In addition, in this region, the El Niño event in 2023 had its effect, which was clearly visible between July and September, with sea levels higher than average, from the mid-tropical Pacific to the coasts of Central and South America.
