Since its discovery, the Great Red Spot has remained essentially constant in size, but in recent years as global warming trends on Earth have picked up and the polar ice caps have receeded, so has the Great Red Spot.
Astronomers have been tracking it since the 1870s, said Glenn Orton, a senior research scientist at NASA'S Jet Propulsion Laboratory who investigates planetary atmospheres. "It is possible that the spot may one day disappear," he added.
If that happens, so too may disappear Earth's polar ice caps - revealing as of yet unknown dangers now frozen deep beneath the Arctic and Antarctic ice masses.
Okay, so I made some of this up. The Great Red Spot really is shrinking, though.
