Watching the moon’s “wobble” may help prevent flooding on Earth

Anew NASA study predicts record flooding in the 2030s due to a combination of rising sea levels and a “wobble” in the moon’s orbit around Earth.

The moon’s wobble: The Earth orbits the sun on what’s known as the ecliptic plane. As the moon orbits the Earth, its relationship with this plane changes — sometimes the moon is above it, and sometimes it’s below it.

Every 18.6 years, the moon completes one cycle of this above-below “wobble,” and during that time, its impact on the Earth’s tides changes.

For half of the cycle, the moon has a stronger effect on the tides — that results in higher high tides and lower low tides. For the other half of the cycle, tides are more moderate — low tide isn’t as low, and high tide isn’t as high.

Rising waters: We’ve known about this cycle since at least 1728, but a new study by NASA has put it in the spotlight.
