Watch NASA's Incredible Timelapse Of Life On Earth Over The Years

NASA captured 20 years of changing seasons in a striking new global map of the home planet.

The timelapse follows two decades of constant image collection from a NASA satellite capturing both seasonal patterns that occur every year and longer term changes. The video showed the earth "breathing", including the ebb and flow of the planet's ice and oceans through a view from space. SeaWiFS gave scientists a continuous view of life on land and in the ocean. The changes in temperature have resulted in more green matter in the Arctic; the shrubs have extended beyond their typical range as areas become warmer than they were in past years.

Dr. Del Geniois now leads a NASA interdisciplinary initiative to find alien life and understands his efforts will also involve rooting through the vastness of space to sort out the spots that might best host living things.

"It's like all of my senses are being transported into space, and then you can compress time and rewind it, and just continually watch this kind of visualization". This starts in the Northern Hemisphere in the spring time, coming and going with the changing of the seasons. Nasa satellites continuously monitored plants on Earth - land and sea - from September 1997 to September 2017. It is helping scientists learn a lot more about global warming and how the earth is changing. Also noticeable to him is the Arctic receding over time - and, though less obvious, the Antarctic, too.

Interestingly, one of North America's five Great Lakes, Lake Erie, is also subject to more algae blooms which can be seen in red and yellow.

Researchers compiled the visualization from satellite imagery.

All this data can provide resources for policymakers as well as commercial fishermen and many others, according to Mr Werdell.

Talking about this is NASA oceanographer Gene Carl Feldman who said, "These are incredibly evocative visualization of our living planet".
