A wobble in the Moon’s orbit lasts 18.6 years. This period includes a time-amplifying phase which increases high tides and their destructive effect. NASA predicts that one such period will occur in the mid-2030s. Moreover, when combined with the rising sea levels, it could lead to flooding across the world.
Climate change and possible flooding
The last couple of decades has been a testament to sudden weather changes on the planet. It has led to a series of floods among other devastations. A new study conducted by the US’s National Aeronautics and Space Administration (NASA) has linked extreme weather conditions to the Moon.
According to the study, a wobble in the moon’s orbit along with the rising sea levels will lead to severe floods. The Moon’s wobble is not a new phenomenon. However, its combination with the rising sea levels is what makes them more dangerous.
What are nuisance floods?
Nuisance floods occur in coastal areas when tides reach almost two feet over the daily average tide. These are highly problematic as they can overwhelm homes and streets. Hence, affect everyday life to a great deal. However, according to NASA studies, these floods are expected to become more irregular and common by the mid-2030s. A majority of the US coastlines are expected to have three to four times the high tides as a present.
Additionally, according to the study, these high tides are expected to last for a decade, if not more. The study warns in advance that the floods will not be spread evenly across the year but, will cluster across a few months. “Low-lying areas near sea level are increasingly at risk and suffering due to the increased flooding, and it will only get worse,” said Bill Nelson, the NASA administrator. “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,” he added.
