Global warming is turning the Arctic green
Today’s Video of the Day from NASA Goddard shows how Arctic landscapes are transforming as temperatures rise and summers become hotter.
A recent study led by Logan Berner of Northern Arizona University found that the Arctic is turning green as warmer air and soil temperatures boost plant growth.
The researchers used landsat data to determine how much vegetation is actively growing on the ground. They determined that between 1985 in 2016, 38 percent of the tundra across Western Eurasia, Alaska, and Canada showed signs of increased greening.
“The Arctic tundra is one of the coldest biomes on Earth, and it’s also one of the most rapidly warming,” said Berner. “This Arctic greening we see is really a bellwether of global climatic change – it’s a biome-scale response to rising air temperatures.”
