World to See a Surge in Sea Level

Climate change and global warming as everyone knows has its wide impact on the Earth. The rising temperature of the Earth will lead to extreme sea levels, which will soon become much more common worldwide, according to a new study.

The findings published in the journal Nature Climate Change claimed that extreme sea levels along coastlines the world over will become 100 times more frequent by the end of the century in about half of the 7,283 locations studied.


In recent times, the world was witness to severe climate and weather events such as record-high temperatures from the Pacific Northwest to Sicily, flooding in Germany and the eastern United States, wildfires from Sacramento to Siberia to Greece.


The authors claimed that an extreme sea-level event that would have been expected to occur once in every 100 years is expected to occur, on average, every year by the end of this century. While the researchers said there is uncertainty about future climate, the most likely path is that these increased instances of sea-level rise will occur even with a global temperature increase of 1.5 or 2 degrees Celsius compared to preindustrial temperatures.

Climate scientist at the Department of Energy’s Pacific Northwest National Laboratory Claudia Tebaldi led the international team of researchers in the Study. The team pooled its data and introduced a novel synthesis method, treating the alternative estimates as expert voters, to map out likely effects of temperature increases ranging from 1.5 C to 5 C compared to preindustrial times. The scientists found that the effects of rising seas on extreme sea level frequency would be felt most acutely in the tropics and generally at lower latitudes compared to northern locations.


Southern Hemisphere, areas along the Mediterranean Sea and the Arabian Peninsula, southern half of North America’s Pacific coast, and areas including Hawaii, the Caribbean, the Philippines and Indonesia are likely to be worst hit. In many of these regions, sea level is expected to rise faster than at higher latitudes. Regions in northern Pacific coast of North America and the Pacific coast of Asia Regions will be less affected.

Tebaldi noted that the globe has already warmed about 1 C compared to preindustrial times. She said that the study gave a more complete picture around the globe.
