Rising sea levels are already starting to flood our coastal communities. You can spot signs of change on days when the tides are extra high – as they will be on August 21, 2017, the day of a total solar eclipse.

Extra-High Tides Are a Preview of Sea Level Rise

Enhanced high tides happen when the sun, Earth, and moon are in near-perfect alignment, as they are every month during the full and new moon phases. At those times, the moon and Sun’s gravity add up to an extra “pull” on the Earth, making our planet’s oceans bulge more than normal. Those extra-high tides can cause flooding in homes and streets along the coast, giving us a preview of how sea-level rise will affect our communities in the future.
