A new study of high-tide floods predicts that the mid-2030s could be catastrophically moist in the coastal areas of the United States and will continue for 10 years.
Led by members of the NASA Sea Level Change Science Team at the University of Hawaii the study High tide floods can occur more frequently on some coasts of the United States, he said. High tide floods, often referred to as annoying floods, already occur regularly in many coastal communities as water flows into routine passages, gardens, and businesses.
Studies show that two factors can converge to exacerbate floods at high tide. It is the rise in sea level and the moon caused by climate change.
The moon “wobbles”
The orbit of the moon is due to its normal “wobble”. According to NASA, this is completely natural and has been recorded as far back as 1728. Half of the 18.6 year cycle of the moon produces lower high tides and higher low tides. The other creates higher high tides and lower low tides.
But NASA says Global sea level rise could push those high tides higher, and Benhamlinton, one of the co-authors of the study and leader of the NASA Sea Level Change Team, has a much longer cycle of the month as water levels rise. Said that it could have a dramatic impact on.
“We are getting closer and closer to the flood thresholds or turning points in these coastal areas,” he said. “The same fluctuations in the past that did not cause floods will now cause floods.”
High tide has already exceeded known flood thresholds across the country. According to a report from the US National Oceanic and Atmospheric Administration Record high tide or flood on a sunny day However, this study shows that high tides often exceed flood thresholds. Studies predict that floods can begin to occur in “clusters” that last for more than a month, depending on the location of the Sun, Moon, and Earth, according to NASA.
“Lowlands near sea level are increasingly endangered and suffering from increased floods, and it only gets worse,” says NASA administrator Bill Nelson. Said.. “The combination of lunar gravitational pull, sea level rise and climate change will continue to exacerbate our coastlines and coastal floods around the world.”
Coastal cities are already in action, but dramatic floods are coming sooner than previously thought
According to Hamrington, coastal cities and urban planners who are already familiar with high-tide floods are working to prevent future damage, but the survey’s rating is higher than expected and longer. It means that the flood will come soon.
“Many of the predictions we scientists give to coastal planners are up to 2100, but the impact we see on how these various factors and processes are combined is much shorter. “He said. “We will see these major and dramatic changes in the next 10 or 2 years.”
