Sea level rise and sea level rise flooding have been gradually increasing for decades, but scientists are predicting a noticeable jump in the next decade. Why? A predictable wobble in the moon’s orbit will place Earth’s tide-driving companion closer to the planet from 2030 to 2040. A closer moon means higher high tides and lower low tides.
When you combine the moon’s stronger gravitational pull on the oceans with climate change-driven sea level rise, we can expect to see even more sea level rise flooding than we’re now witnessing in coastal communities. In fact, experts are predicting the moon wobble will result in sea level rise flooding conditions that were not expected until the end of this century. For example, scientists estimate San Francisco will experience five times more high-tide flood days in the next decade than it does now.
To arrive at their disturbing conclusion, NASA researchers reviewed data from tide gauges located in coastal communities in every state and territory but Alaska, which, due to its position on the globe, is not expected to face higher tides due to the moon wobble. The research was published in the journal Nature Climate Change.
Buyers and owners of real estate currently experiencing sea level rise flooding or located in communities that flood need to add the wobble into their long-term property ownership decisions. Flooding is already forcing the government and property owners to spend billions of dollars to fend off floodwaters and protect critical infrastructure. A sudden leap will only worsen property damage and result in higher outlays for maintenance, taxes and insurance.
