Natural disasters that occur every hundred years will now occur every year due to global warming

- Global warming will cause sea levels to rise worldwide

- Rising sea levels in the world will affect southern areas sooner than northern ones

WASHINGTON: Natural disasters that used to hit the coast once every 100 years will now continue to strike every year until the end of this century due to global warming, a study has found. The study, published in the journal Nature Climate Change, focuses specifically on rising water levels.

Researchers predict that rising temperatures will increase water levels by half a percent in half of the world's 8,3 coastal locations.

At a time when there is uncertainty about the future of the climate, the researchers said that even if global temperatures rise by one and a half to two degrees, the water level will rise.

Claudia Tebaldi, a meteorologist who led the team of researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory, said the effects of rising sea levels in the world would affect areas south more than north.

Areas most likely to be affected include the Mediterranean coast in the Southern Hemisphere, the Arabian Peninsula and the Pacific coast of North America, as well as Hawaii, the Philippines, Indonesia and the Caribbean islands.

The North Pacific Coast of North America and the coastal areas of the Pacific Coast of Asia will be relatively less affected. Different conditions have been hypothesized in this study due to different factors.

In the worst case scenario, the water level could rise 100 times by 2100 due to a rise of one and a half degrees. So it can also create a situation at the opposite end that even if the temperature rises by five degrees, it may not have much effect on 90% of the places.
