Sea levels are at risk of rising by as much as a century in just 30 years

The American coastline could expect a sea ​​level rise over the next thirty years. This problem started during the 20th century and the big cities of the eastern United States are victims of it. I’rising waters along the Atlantic coast has accelerated very rapidly over the past 2,000 years. For this purpose, costly floods regularly hit cities, according to a government report.

By 2050, the american coast sea will rise 10 to 12 inches (0.25 to 0.3 meters) higher. The situation could be even worse for parts of Louisiana and Texas, as the waters will rise by a foot and a half (0.45 meters). The 111-page report was released Tuesday by the National Oceanic and Atmospheric Administration along with six other federal agencies.

Nicole LeBoeuf, director of NOAA’s National Ocean Service, warned of the high cost of flood damage. It is that a large part of American industry and 40% of the population are based along the coast.

Worst sea level rise likely to occur after 2100

According to William Sweet, an oceanographer with the Oceans Service and lead author of the report, the peak of long-term sea level rise will probably occur only after 2100. This would be due to the melting ice caps Antarctica and Greenland. The expansion of warm water would cause ice caps to melt and glaciers to add water to the oceans.

The report “equivalent to NOAA sending a red flag” on accelerating sea level rise, said University of Wisconsin-Madison geoscientist Andrea Dutton. Note that this specialist in sea level rise did not participate in the federal report.

The rise in the United States will be higher than the world average

The coastal flooding that affect the United States currently “will be taken to a whole new level in just a few decades”, according to Andrea Dutton. Be aware that sea level rise differs from place to place. This is due to land subsidence, currents and thewater from melting ice.

The United States can also expect sea level rise to be slightly higher than the global average. It should be pointed out that the Gulf and Eastern Coasts would experience the largest increase in all of the United States.
