US coastlines will face increasing flooding in the mid-2030s because of the regular lunar cycle that will magnify rising sea levels caused by climate change as per the research led by Nasa scientists.
According to the reports, an important factor that has been identified by scientists is a regular wobble in the moon’s orbit which is the first identified in the 18th century – that takes 18.6 years to complete and the moon’s gravitational pull helps drive Earth’s tides.
The report further added that in half of this lunar cycle, Earth’s regular daily tides are diminished, with high tides lower than usual and low tides higher than usual. In the cycle’s other half, the situation is reversed, with high tides higher and low tides lower.
The expected flooding will result from the combination of the continuing sea-level rise associated with climate change and the arrival of an amplification part of the lunar cycle in the mid-2030s, the researchers said.
The researchers studied 89 tide gauge locations in every coastal US state and territory aside from Alaska. The effect of the dynamic applies to the entire planet except for far northern coastlines like in Alaska. The prediction pushes previous estimates for serious coastal flooding forward by about 70 years.
