Because of human activity .. Earth will face hurricanes without precedent

A research team from the Japan National Institute for Environmental Studies (National Institute for Environmental Studies, Japan) indicated that the rise in surface temperatures of water in the western Pacific Ocean off the Japanese coast would not have occurred without human activity due to the climate changes currently taking place in the world.

Massive damage

Last August, the water surface in that area set a new record, which is 30 degrees Celsius, and it continued that way until mid-September.

According to the study of this team, which was published in the journal "Geophysical Research Letters" and announced by the institute in an official statement on January 14th, this is what raised the strength of tropical cyclones, such as "Hicheng", Causing huge damage to East Asian countries.

It is known that any hurricane draws its energy from the heat of the ocean surface that flows over its surface, and therefore the higher the temperature of the ocean surface the stronger and more deadly the hurricane, because it will rotate with greater speed and force.

Human activity and a cautious future

To reach these results, this team used 31 mathematical models to study the relationship between warming of the ocean surface and rising levels of carbon dioxide in the atmosphere, due to human use of fossil fuels, then compare that with other natural effects of volcanoes and solar activity, and then show the size of the impact of human activity after these Comparison.

On the other hand, the study worked on extending straight lines to predict what could happen up to the year 2100, and the results came to say that what represents a boom or record now in ocean surface temperatures, will become the natural average by the middle of this century.

And a research report from the US National Oceanic and Atmospheric Administration (NOAA) has shown that the number of dangerous hurricanes - of scale 4 and 5 - has increased from an average of 10 hurricanes per year in the 1970s, to reach in the 1990s to 18 hurricanes per year, due to the change Climatic.

It is expected - according to the report - that the number of dangerous hurricanes will continue to rise, with the increase in their destructive capacity, along with their speed and size, which may lead over time to the emergence of very dangerous hurricanes that have not been witnessed in our oceans before.

This comes in the context of a recent announcement by the US Aerospace and Aviation Agency (NASA), which says that 2020 was the warmest year in the history of measurement for about a century and a half, slightly more than 2016, which for the past 5 years has been the holder of this record.
