Could a 'Super Moon' cause climate chaos?
Next week, the moon will make its closest approach to Earth in almost 20 years. Some fret that earthquakes, volcanic eruptions, and other disasters will follow
On March 19th, the moon will travel as close to earth as it's been in nearly 20 years, alarming astrologers if not the scientific world.

eep your eyes on the night sky on March 19, also known as the evening of the extreme Super Moon, when the lunar sphere comes as close as it ever has, or will, to Earth. Some believe the astronomical event will be followed by catastrophic storms, earthquakes and other natural disasters. Here's why:

What exactly is a "Super Moon"?
The term refers to the unusually large new (or full) moon that earthlings see when the moon travels almost as close as it can to Earth. An "extreme Super Moon" occurs when the moon reaches its absolute closest point. On March 19, the moon will be only 221,556 miles away — the first extreme Super Moon in nearly 20 years.

Should we be concerned?
Those who believe in horoscopes might be. Some astrologers (not astronomers) say this natural wonder signals the beginning of a "moonageddon," coinciding with enormous storms, earthquakes and floods. Kit Karson at Psychic Cosmos further predicts that the financial markets could collapse as prices surge into "panic mode."

Is this for real?
Astrologists point to history to validate their predictions, says Ben Yakas at Gothamist. Both the New England hurricane of 1938 and the Australian Hunter Valley floods of 1955 happened during Super Moons, they say. The last Super Moon came in 2005, at around the same time as Hurricane Katrina and the Indonesian tsunami.

Is there any science backing these theories up?
Absolutely none, says Pete Wheeler of the International Center for Radio Astronomy. All that will happen next week is that the Earth will experience a "lower than usual low tide and a higher than usual high tide." A Super Moon, he concludes, is "nothing to get excited about."

But what about extreme weather during past Super Moons?
It's just coincidence, says astronomer David Reneke. "'If you try hard enough you can chronologically associate almost any natural disaster or event to anything in the night sky." In the past, he adds, people thought the sun would be pulled apart when the planets aligned. "It didn't happen." And the catastrophic events cited by excitable astrologers didn't even happen that close to Super Moons, points out John Metcalfe at TBD. The Hunter river flooded in February 1955, "two whole months before and after bookending Super Moons."
