Antarctica starting to turn green, scientists say

Researchers in Antarctica have discovered rapidly growing banks of mosses on the ice continent's northern peninsula, providing striking evidence of climate change in the coldest and most remote parts of the planet.

Amid the warming of the past 50 years, scientists found two species of moss undergoing the equivalent of growth spurts.

With mosses that once grew less than 1mm a year, now growing more than 3mm a year on average, the surface mosses build up a thin layer in the summer, then freeze over in winter.

As layer builds on top of layer, older mosses subside below the frozen ground and are remarkably well-preserved.
