Nasa Study reveals rise in sea levels in 2030s; but the reason is bigger than you expect

A recent study conducted by American space agency, NASA, says that a 'wobble' in Moon's orbit combined with rising sea levels due to climate change will lead to devastating floods around coastal areas Earth in 2030s.

Climate change has always caused sudden weather changes on Earth, which has led to floods in many countries, especially the United States. The new study has gone a step ahead to link extreme weather events with Earth's neighbor, the moon.

Currently occurring in coastal areas when the tide reaches about 2 feet above the daily average high tide, these floods are called as nuisance floods as the events are much more problematic for businesses affecting their everyday life. These nuisance floods will become more frequent and irregular by mid-2030s, according to Nasa study. A majority of US coastline will see three to four times increase in high tides for at least a decade, according to the study.

Explaining the impact of the Moon on the flooding on Earth, author Phil Thompson, an assistant professor at the University of Hawaii, said that the wobble in the Moon's orbit takes 18.6 years to complete. While the wobble has always been there, what makes it dangerous is that it will combine with the rising sea levels due to the planet's warming, said Thompson.

In half of these 18.6 years, the Earth's regular tides are suppressed: high tides are lower than normal and low tides higher than normal. In the other half, the effect is reversed, which is called the tide-amplifying phase of the Moon. The next time this cycle is expected in 2030s, which will severely affect the normal life, especially in coastal areas, according to Thompson.

Moreover, It has also warned that these floods won't be spread out evenly through the year, and are expected to occur over the span of just a few months. According to Nasa administrator Bill Nelson. “Low-lying areas near sea level are increasingly at risk and suffering due to the increased flooding, and it will only get worse,”
