All coasts of the United States are facing rapidly increasing high-tide floods, thanks to the “wobble” of the lunar orbit, which works in tandem with climate change rises...
New research from NASA and the University of Hawaii recently published in the journal Natural climate changeWarns that future changes in the lunar orbit could lead to record floods on Earth over the next decade.
By mapping the US National Oceanic and Atmospheric Administration (NOAA) sea level rise scenarios, flood thresholds, and astronomical cycles, researchers found that in the 2030s, when the next month’s “wobble” is expected to begin, the United States We have discovered that floods in coastal cities can be several times worse. .. They expect the floods to cause serious damage to the infrastructure,..
Although the study highlights the dire situation facing coastal cities, lunar wobble is actually spontaneous and was first reported in 1728. The orbit of the moon is about 18.6 years, causing both high and low tide periods and is not dangerous. Their own rights.
“Half the 18.6 year cycle of the Moon suppresses the normal daily tides of the Earth. High tides are lower than normal and low tides are higher than normal.” NASA explains.. “In the other half of the cycle, the tides are amplified. High tides are high and low tides are low. Global sea level rise pushes high tides in only one direction. Therefore, in the month of 18.6. Half of the cycle counteracts the effects of rising sea levels at high tide, and the other half increases its effects. “
But this time, scientists are more worried. The next high tide floods are expected to be more intense and frequent than ever, as sea levels rise due to climate change, already exacerbating harsh forecasts.
In 2019, NOAA reported more than 600 such floods. Scientists expect sea levels to rise three to four times more in the mid-2030s as sea levels rise for another decade.
Studies show that these floods often exceed national flood thresholds and can occur in clusters that last for more than a month, depending on the location of the Moon, Earth, and Sun. During certain adjustments, floods can occur as often as daily or every other day.
“Lowlands near sea level are increasingly endangered and suffering from increased floods, and it only gets worse,” said NASA administrator Bill Nelson. “The combination of lunar gravitational pull, sea level rise and climate change will continue to exacerbate our coastlines and coastal floods around the world.”
Almost all coastlines in the mainland United States, Hawaii and Guam are expected to face these effects.It has already made hundreds of thousands of square miles of coastline uninhabitable and is expected to evacuate more than 100 million people worldwide by the end of the century.
Researchers hope that their findings will lead to more devoted efforts to prevent as much damage as possible to both the environment and people’s lives, before it’s too late. Floods at high tide do not require as much water as hurricanes, but the real danger lies in their frequency.
“It’s the effects that build up over time that affect us,” said lead author Phil Thompson. “If floods occur 10 to 15 times a month, businesses will not be able to keep their parking lots underwater. People will lose their jobs because they can’t get a job. The penetration of sespool is public health. It will be the above problem. “
