February 22, 2001 - (date of web publication)

YEAR OF PROMISE, YEAR OF CHANGE

Ecclesiastes says that generations come and go but the Earth endures forever. But what do the sciences say? In 2000, researchers who study the Earth in a variety of disciplines sought knowledge and understanding about a host of interrelated subjects. Some of those subjects concern discrete, focused questions about the world, as in the case of research that looked for "missing" tidal energy in the oceans. But much of the last year’s research dealt with topics fundamentally related to each other, essentially describing a complex, interwoven system at the roots of our planet.

The Earth may endure, but as passengers on it we humans grow and learn. In that light we present a collection of Earth science highlights to spring from NASA’s Goddard Space Flight Center in 2000.
