Amazing NASA map shows how climate change altered the face of our planetTHIS amazing NASA map of Earth from multiple satellites shows climate change has altered the face of our planet in the past 20 years.
The data visualisation, released this week, shows Earth's fluctuations as seen from spaceNASA
Polar ice caps and snow cover are shown ebbing and flowing with the seasons.
Varying ocean shades of blue, green, red and purple depict the abundance or lack of undersea life.
Two decades of imagery from September 1997 to this past September are crunched into minutes of viewing.
NASA oceanographer Jeremy Werdell said: "It's like watching the Earth breathe, it's really remarkable.
This map shows the biology changes on earth as viewed from space. The images focus on changes in the Middle East
"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 visualisation."
Werdell said the visualisation released this week shows spring coming earlier and autumn lasting longer in the Northern Hemisphere.
And he notices the Arctic ice caps and the Antarctic receding over time.
Werdell was struck by "this hugely productive bloom of biology" that exploded in the Pacific along the equator from 1997 to 1998 when a water-warming El Nino merged into cooling La Nina.
The algae bloom is evident by a line of bright green.
In Lake Erie in Canada, more and more contaminating algae blooms are apparently appearing red and yellow.
The NASA data can provide resources for policymakers as well as commercial fishermen and many others, according to Werdell.
Programmer Alex Kekesi of NASA's Goddard Space Flight Center in Maryland said it took three months to complete the visualisation, which was made using satellite imagery.
Thanx NASA

Absolutely awesome article. Videos and graphics are wonderful and teaches us so much. It is amazing actually seeing the changes to earth from space. If any friendly aliens are watching, I wish they would stop by and help us. NASA does marvellous work and they care about the planet. Someone from NASA should tie Mr Trump to a chair and make him watch some videos and listen to scientific proof of climate change.
ReplyDeleteGreat job Jonny
Love Aunt Jeannie
My teacher at Sci-Port told me to look for videos to go with my graphics . He said NASA makes a lot of videos , they don't mind sharing . Mr . Wily looked at my post , he said good job , he was very impressed with Man's post .
ReplyDeleteAs long as Mr. Trump is in office , I do not think any aliens will dare visit us , they will think if this is the best we have to offer our world is not worth visiting , they think because he is our leader , everyone is as crazy and stupid as he is .
Mr . Trump is a joke to the people that elected him for president . Some of us do have a bit of sense , it is just to bad we are not old enough to vote .
Thank you
Love you too
