NASA predicts rapid flooding in 2030s due to Moon's 'wobble'

In the mid-2030s, the alignment of rising sea levels with a lunar cycle will cause coastal cities all around the US to begin a decade of dramatic increases in flood number, said the NASA study.

High-tide floods will increase rapidly across the world, especially the United States, in the mid-2030s and it is linked with Earth's neighbour, the Moon, said National Aeronautics and Space Administration (NASA).

According to a study by the American space agency, a 'wobble' in the Moon's orbit combined with sea-level rise (SLR) due to climate change will lead to devastating high-tide floods (HTF).

HTF, also called nuisance floods or sunny day floods, are already a familiar problem in many cities on the US Atlantic and Gulf coasts. However, in the mid-2030s, the alignment of rising sea levels with a lunar cycle will cause coastal cities all around the US to begin a decade of dramatic increases in flood numbers, said the study that takes into account all known oceanic and astronomical causes for floods.

“The combination of the Moon’s gravitational pull, rising sea levels, and climate change will continue to exacerbate coastal flooding on our coastlines and across the world,” said NASA Administrator Bill Nelson.
