Extreme sea level events will be more frequent along coastlines around the world

Dr. ebru kirezci, a marine engineering researcher at the University of Melbourne, co-author of the study, said that the regions where the frequency of extreme sea level is expected to increase rapidly include the southern hemisphere and subtropical regions, the Mediterranean and Arabian Peninsula, the southern half of the Pacific coast of North America, and regions including Hawaii, the Caribbean, the Philippines and Indonesia

“we can also infer from this study that by 2100, most coastlines in eastern, southern and southwest Australia will be affected, and this extreme sea level will appear almost every year,” Dr. kirezci said

“even if the global temperature rises by 1.5 ℃, this increase in extreme sea level frequency will occur. Moreover, these changes may come earlier than the end of this century, and there will be a 100 fold increase in extreme events in many places even before 2070”

the lead author of the study, Dr. Claudia tebaldi, a climate scientist at the Northwest Pacific National Laboratory of the U.S. Department of energy, said that even at 1.5 degrees, the rise of sea level will be dramatic, It is not surprising that it will have a substantial impact on the frequency and amplitude of extreme sea levels. The researchers called for more detailed research to understand how these changes will affect communities in different countries. They added that the physical changes described in the study will have different effects on a local scale, depending on several factors, including the vulnerability of the region to rising water levels and the readiness of a community to change

“public policy makers should take note of these studies and strive to improve coastal protection and mitigation measures.” Dr. kirezci said: “building dams and sea walls, retreating from the coastline, and deploying early warning systems are some steps that can be taken to adapt to this change
