World sea level rises by more than 10 cm in about 30 years, and its speed has increased in recent years

WMO = World Meteorological Organization has released a report that the average sea level in the world has risen by more than 10 centimeters in about 30 years until 2021, and the speed has increased in recent years.

On the 18th, WMO released a report on the current state of the world's climate in 2021 based on data submitted by meteorological authorities and research institutes around the world.

According to it, between 1993 and 2021, the world's average sea level rose 10.2 centimeters, and in recent years its rate has increased.

The report blames thick ice layers such as Antarctica, ice sheets melting into the sea, and increasing seawater levels, with rising sea levels for hundreds of millions of people living along the coast. It is said that it may have a great impact on people.

WMO Secretary-General Tarras said at a press conference, "The average sea level in the world rose by about 2 mm a year 20 years ago, but recently it has been observed to rise by 4.5 mm a year, which is a record rise. I rang the alarm bell.

This announcement by the WMO is likely to influence the discussions at the United Nations Conference on Climate Change Countermeasures "COP27" to be held in Egypt.

Expert “Preparing for unprecedented heavy rain by utilizing weather information”

WMO = World Meteorological Organization Atsushi Goto, who compiled this report, said, "When the sea level rises, the risk of storm surges and inundation increases in coastal areas. Japan surrounded by the sea is an exception. The higher the average sea level, the higher the risk of storm surges when a typhoon hits, and the disappearance of sandy beaches may have an impact on tourism resources and ecosystems. "

On top of that, "As warming progresses, the intensity and frequency of heavy rains tend to increase in Japan. In Japan, the season of rainy seasons and typhoons will soon come, but due to the effects of climate change, heavy rains that exceed the amount of rain experienced in the past. I want you to make the best use of weather information and prepare for it, keeping in mind that there is a possibility that it will rain. "
