Watch: Moon's 'wobble' to cause record floods in 2030s, says NASA study

The next decade may see regular high-tide floods in coastal cities in the United States of America, as per a NASA study. These floods, possibly occurring in clusters even a month long, will be caused by rise in sea level due to global warming exacerbated by the Moon's 'wobble'. This wobble is a regular feature and one half of the 18.6 year cycle suppresses tides on earth, while the other half amplifies them. Watch the full video for more.
