A team of researchers studying satellite images of the Alps made a concerning find: Since 1984, most of the high-elevation parts of European mountain range have seen an increase in vegetation. While that might not sound particularly troublesome, this “greening” is likely due to global warming and may be facilitating a feedback loop that is also reducing snow cover.
