The Times They Are a-Changin'

December 30, 2014

From NASA's Earth Observatory:

With consistent records of satellite observations that date back decades, it's possible to literally see Earth changing over time. Some changes are part of Earth's natural atmospheric and geologic rhythms. The responsibility for other changes, such as the shrinking of the Aral Sea and the Antarctic ozone hole, falls squarely on humanity’s shoulders. Our World of Change series documents how our planet’s land, oceans, atmosphere, and Sun are changing over time. See the World of Change galleries at
