The Gulf of Mexico’s coastlines were specifically mentioned as an area of concern because they are more vulnerable to flooding due to relatively narrow sea-level distributions. During that time, “a leap in flood numbers” is expected along the U.S. The next cycle that is expected to amplify tides again will happen in the mid-2030s, NASA says. In the other half of the cycle, tides are amplified: High tides get higher, and low tides get lower,” the study says. “In half of the Moon’s 18.6-year cycle, Earth’s regular daily tides are suppressed: High tides are lower than normal, and low tides are higher than normal. That mixed with rising sea levels could create risk for people who live in coastal communities, according to NASA. ![]() The wobble affects the moon’s gravitational pull and can either suppress or amplify ocean tides on earth. The moon's gravitational pull helps drive Earth's tides. ![]() A key factor identified by NASA scientists is a regular 'wobble' in the moon's orbit - first identified in the 18th century - that takes 18.6 years to complete. It is a cyclical shift in the moon’s orbit every 18.6 years and they’ve been recorded since 1728. coastlines could face increased flooding in the 2030s and the culprit A phenomenon NASA calls a ‘moon wobble’, mixed with rising sea levels caused by climate change. will experience rapidly increasing high-tide flooding due to “moon wobble” and climate change, according to a new study.īut what is “moon wobble”? It isn’t a new phenomenon, according to NASA. Hamlington says the study should be “eye-opening” and cautioned that city planners should prepare accordingly.Editor’s note: Read more climate reporting on KSAT’s Forecasting Change page. And what we found is that this increase in coastal flooding is really going to be increased significantly in the coming decades, specifically in 2030 to 2040." "So in the coming decades, as sea level continues to increase from global warming, and it's increasing across the globe, the combination of sea level rise associated with global warming and then natural drivers of sea level variability, so the things causing sea level to go up and down just naturally in the ocean, are going to combine to cause coastal flooding. The moon's orbit, which affects the Earth's tides, has a natural 'wobble' every 18.6 years that causes extremely high and low tides. NASA’s ‘Sea Level Change’ Team Lead Ben Hamlington explains the prediction. A moon 'wobble' will contribute to an increase in severe flooding in the mid-2030s, NASA has warned. ![]() The alarming prediction pushes previous estimates for serious coastal flooding forward by about 70 years, the study showed. Louis Fernandez walks along a flooded street in Miami Beach in September 2015. coastlines could face increased flooding in the 2030s – and the culprit?
