Global warming melting Arctic regions, climate change is happening: NASA

A new NASA study has found out that due to the changing climate, Arctic regions of North America are getting greener, with almost a third of the land cover looking more like landscapes found in warmer ecosystems. With 87,000 images taken from Landsat satellites, converted into data that reflects the amount of healthy vegetation on the ground, the researchers found that western Alaska, Quebec and other regions became greener between 1984 and 2012. The new Landsat study further supports previous work that has shown changing vegetation in Arctic and boreal North America. Using ~30 years of satellite data, scientists track vegetation changes in Alaska and Canada:http://t.co/1Sg8S1yQ0Xhttp://t.co/0Lw0MDKkBj— NASA (@NASA)June 2, 2016Landsat is a programme that provides the longest continuous space-based record of earth's land vegetation in existence. “It shows the climate impact on vegetation in the high latitudes,” said Jeffrey Masek, scientist at NASA’s Goddard Space Flight Centre in the US.
