The famous snow-capped peaks of the Alps are fading fast and being replaced by vegetation cover – a process called 'greening' that is expected to accelerate climate change, a study said Thursday.
, was based on 38 years of satellite imagery across the entirety of the iconic European mountain range.
For their analysis, the team examined regions at 1,700 meters above sea level, to exclude areas used for agriculture. They also excluded forested areas and glaciers. Secondly, the researchers compared the amount of vegetation using wavelength analysis to detect the amount of chlorophyll present, and found plant growth increased across 77 percent of the zone studied.Greening happens in three different ways: plants begin growing in areas they previously weren't present, they grow taller and more densely due to favorable conditions, and finally particular species growing normally at lower altitudes move into higher areas.
