The moon "sways". There is no other way to say it. A small change in the moon's orbit - a swing, if you will call it that - has raised questions about the effect such a slight swing could have on Earth.
In a study published in the journal Nature Climate Change in June, scientists say that by 2030, the swing will have enough effect on the moon's gravitational pull to affect sea level rise. What does this mean; Many coastal areas will experience more and more frequent floods. Climate change is already causing its levels to rise sea.
In cities already experiencing such "floods", the risk of more frequent floods could cause significant damage and concern in the not-too-distant future.
NASA Administrator Bill Nelson said: "The combination of the moon's gravitational pull, rising sea levels and climate change will continue to exacerbate flooding off our coasts and around the world. "NASA's Sea Level Change team provides critical information on protecting and preventing damage to the environment and livelihoods of people affected by floods."
Scientists have known about oscillations on the moon for centuries - first discovered in 1728 - but the point is that sea levels have already risen to the point where we must now consider how the Moon's existing tidal cycles will affect the universe.
Experts divide the moon's orbit into two halves. During the first half, the tides on Earth are suppressed, with the high tides being lower than average and the low tides being higher than average - a kind of "meeting in the middle". However, in the other half, the result inverted. Tides are getting louder: High tides are getting louder and low tides are getting louder.
The point is that in the 2030s, when sea levels are expected to rise significantly, Earth will be in the enhanced part of the tide cycle. High tides will be higher than ever, with coastal flooding expected to increase dramatically.
With this new model, scientists can predict when and where these floods are most likely to occur - and possibly save both lives and livelihoods.
