The wobbling of the moon's orbit will lead to devastating floods in the 2030s

Climate change has already increased the frequency and severity of hurricanes and other extreme weather events around the world.

Recently, scientists have found that there is another threat on the horizon that coulddamage the U.S. coast.

According to the National Oceanic and Atmospheric Administration (NOAA), there were more than 600 tidal floods in the U.S. in 2019.A new study conducted by NASA has shown that such cataclysms will occur much more often in the United States by the 2030s. 

A study published in the journal Nature Climate Change found that there will be no additional flood daysCoastal areas, which account for two to three floods per month, are waiting forMore than 12 such events in 30 days.

Researchers warn that theselong seasons of coastal flooding will affect people's lives. They could lose their livelihood if the authorities do not start flood planning now.

The projected increase in the number of flood days is due to several factors.

First, the rise in sea levels.As global warming warms the atmosphere, glacial ice is melting at a record rate, dumping huge amounts of melt water into the ocean. As a result, according to NOAA, the average world sea level has risen by a quarter of a meter since 1880. By 2100, sea levels could rise from 0.3 m to 2.5 m above the 2000 level.

While sea level rise will itself increase the frequency of floods, there is another factor that will affect the situation.

The Moon influences the tides , but the force of gravity is not the same from year to year.its position relative to the Earth in a rhythmic 18.6-year cycle. tides on Earth , resulting in lower tides and higher tides.According to NASA, in the second half of the cycle, the tides intensify with higher tides and lower tides. 

The next cycle of increased tides begins in the mid-2030s. By then, global sea levels will rise enough to make these high tides particularly devastating.
