Extreme Sea Levels Will Become 100x More Common Along the World’s Coastlines.
According to new research by an international team of scientists, global warming will cause exceptional sea levels to occur practically every year by the end of the century, affecting major coastlines throughout the world.
The study, which was just published in Nature Climate Change, forecasts that extreme sea levels along coastlines throughout the world will become 100 times more common by the end of the century in approximately half of the 7,283 areas evaluated as a result of rising temperatures.
The Southern Hemisphere and subtropical areas, the Mediterranean Sea and the Arabian Peninsula, the southern half of North America’s Pacific Coast, and areas such as Hawaii, the Caribbean, the Philippines, and Indonesia, according to co-author and ocean engineering researcher Dr. Ebru Kirezci of the University of Melbourne, are areas where extreme sea levels are expected to increase faster.
“What we can also extrapolate from this study is that by 2100, much of Australia’s eastern, southern, and southwestern coastlines will be hit by these severe sea levels on an almost annual basis,” Dr. Kirezci stated.
“Even if global temperatures rise 1.5 degrees, this increased frequency of severe sea levels will occur.” And the changes are expected to happen sooner than the end of the century, with many places seeing a 100-fold increase in extreme occurrences by 2070.” Dr Claudia Tebaldi, the study’s lead author and a climate scientist at the US Department of Energy’s Pacific Northwest National Laboratory, said it’s no surprise that sea level rise will be dramatic even at 1.5 degrees, and that it will have significant effects on extreme sea level frequency and magnitude.
“This research provides a more comprehensive picture of the world. Dr. Tebaldi explained, “We were able to look at a wider range of warming levels in extremely fine spatial detail.”
More research is needed to understand how the changes would affect communities in different countries, according to the experts. They went on to say that the physical changes described in the paper will have various local implications, based on a variety of factors such as how sensitive the place is to rising waters and how prepared a community is for change.
“These research should be taken into account by public authorities, who should endeavor to improve coastal protection and mitigation measures.” “Some of the efforts that can be done to adapt to this change include building dykes and sea walls, retreating from shorelines, and implementing early warning systems,” Dr. Kirezci stated.
