NASA warns that the moon will “wobble” to bring about a serious flood surge in the 2030s | US News

NASA warns that lunar “wobble” will contribute to the increase in severe floods in the mid-2030s.

The lunar orbit, which affects the Earth’s tides, has a natural “wobble” every 18.6 years, causing very high and low tides.

In a new study published by Nature Climate Change, NASA’s sea level change science team calculated that the next wobble in the mid-2030s would be amplified. Sea level rise due to climate change..

Almost all coastlines in the mainland United States, as well as Hawaii and Guam, can experience spikes in high-tide floods when exposed to pressure from the high seas.

However, researchers have found that the northern coastline, including Alaska, will be spared for another decade or more due to the increase in these land areas due to long-term geological processes.

This study is the first to take into account all known marine and astronomical causes of floods. NASA Said.

Storm surge floods, also known as nuisance floods or sunny day floods, occur when tides fill densely populated areas, not due to high tides due to extreme weather or excessive precipitation.

According to the US National Oceanic and Atmospheric Administration (NOAA), floods can overwhelm storm drains, close roads and endanger infrastructure.

Bill Nelson, NASA’s administrator, said: “Lowlands near sea level are increasingly endangered and suffering from increased floods. They only get worse.

“Moon gravitational force, sea level rise, and Climate change It will continue to exacerbate our coastlines and coastal floods around the world. “

“It’s the effects that have accumulated over time that affect us,” added Phil Thompson, an assistant professor at the University of Hawaii and the lead author of the new study.

Moon wobble amplifies sea level rise

Floods at high tide are less dramatic than hurricane surges and have less water, so they are often considered not an imminent problem.

“But if there are 10 to 15 floods a month, companies will not be able to keep their parking lots underwater,” Thompson said.

“People lose their jobs because they can’t get a job. Penetration of cesspool is a public health problem.”

According to NASA, floods occur in clusters and can last for more than a month at a time, depending on the location of the moon, sun, and Earth.

Residents of some cities could see floods every day or two days because the moon and the earth lined up with each other in a particular way and the sun lined up in a particular way.

Benhamrington, who heads NASA’s sea level change team, said the study is essential for coastal city planners who tend to focus on preparing for extreme weather events beyond chronic floods.

“From a planning perspective, it’s important to know when it will increase,” Hamrington said.

“Understand that all events are concentrated in a particular month, or that there can be more serious floods later in the year than in the first half. This is useful information.”

Although the moon is currently in the 18.6 year wobble tide amplification section, most US coastlines have not yet seen sufficient sea-level rise to notice the effects of floods.

By the mid-2030s, the next time wobble enters the tidal amplification phase, world sea levels will rise for another decade due to climate change.

In this study, “NOAA’s widely used sea-level rise scenarios and flood thresholds, the number of times these thresholds are exceeded each year, the astronomical cycle, and statistical representations of other processes such as El Nino events are mapped. By doing so, we predicted results up to 2080. It is known to affect the tide. “
