Project Scientist Comments on New NASA Timelapse
A true understanding of our planet requires us to keep a keen eye on its living inhabitants. With NASA's fleet of Earth-observing satellites, scientists can track worldwide changes in vegetation, marine life, human development and more. We've seen fisheries evolving, deserts expanding, spring coming earlier and fall coming later. Seeing these kinds of changes occur all over the world has taught us a lot about the ingredients for life and the environmental conditions that can sustain it.
In this video, PACE Project Scientist Dr. Jeremy Werdell comments on the new time-lapse of life on our entire planet over the last two decades, and discusses how NASA data are being used to study the health of ocean ecosystems. Credit: NASA GSFC
