Suara.com – United States space agency (NASA) predicts that by mid-2030 there will be a lot rob flood on the coast due to the shaking of the the orbit of the moon and rising sea levels associated with global warming.
The main factor that will trigger tidal flooding in mid-2030 is the wobble in the moon’s orbit. This wobble is a common phenomenon, occurring every 18.6 years.
Moon cycle this, so it was reported Reuters last weekend, it was first discovered by scientists in the 18th century.
This cycle also affects the tides of the oceans on Earth. In the first half of the cycle, the daily tidal wave was lower than usual. While at low tide, the water level is actually higher than usual.

Then in the second half of the cycle, the opposite will happen. Sea level is higher at daily high tide and at low tide, sea level is lower.
The increasing frequency of tidal floods, explained the researchers, will occur due to a combination of this lunar cycle and rising sea levels due to climate change.
“The background is, there has been a rise in sea levels associated with global warming. Sea levels are rising everywhere,” said Ben Hamlington, lead author of this NASA study.
“So what we found is that the effect of the lunar cycle, along with rising sea levels, will cause flooding, especially in the period 2030 to 2040,” Hamlington further explained.
In the study, Hamlington and his team examined 89 tidal wave measurement locations within the United States, except for Alaska. The results found that the combined effects of the lunar cycle and rising sea levels will occur worldwide, except for areas in the far north such as Alaska.
