American space agency NASA has warned that the world may witness massive coastal flooding starting in the mid-2030s due to a "wobble" in the moon's orbit. 

According to a study by NASA, Earth is expected to see a four-fold rise in the number of floods as the lunar cycle accompanied by the climate crisis will lead to a rise in sea levels. 

The study by members of the NASA Sea Level Change Science Team from the University of Hawaii has revealed that the long-term geological processes are leading to rise in far northern coastlines’ land areas and flooding will begin in these areas after a decade.

Published in the journal ‘Nature Climate Change’, the study is the first to take into account all known oceanic and astronomical causes for floods, NASA said in a news release. 

The National Oceanic and Atmospheric Administration had recorded more than 600 high-tide floods in 2019. 

However, these floods will occur in clusters lasting for over a month or longer in the 2030s, the study said. However, the phenomenon would depend on the positions of the Moon, Sun and Earth, while some cities are likely to witness floods every day.
