The "browning" process has dramatically transformed the terrain.
Gone are the days when we could count on the Arctic landscape to be painted in shades of white.
The permafrost beneath the snow and ice is no longer permanently frosty, and as it melts, write researchers in a new study, it’s muddying up the once-pristine terrain — quite literally.
In a startling photo accompanying the study, an array of Arctic and sub-Arctic lakes seem to spew filth from within, making the landscape look like the surface of an alien world.
The paper, published in Limnology and Oceanography Letters on Friday, describes the visible effects the thawing permafrost has on the surface of the neighboring terrain, many feet above it.
As climate change warms the Earth and coaxes the permafrost out of its continually frozen state, a process called “browning” occurs, the researchers write.
During this process, organic carbon once trapped deep in the permafrost seeps upward into the region’s lakes and ponds, suffusing them with a filthy brown hue.
Meanwhile, the way the permafrost cracks the landscape above it creates fissures that divide the surface into eerie polygonal shapes.
In the image below, supplied in a release by Quebec, Canada’s INRS (*Institut national de la recherche scientifique), the muddiness of the browning lakes sharply contrasts with the clear blue of the larger body of water alongside them, though even it too shows sinister brown tendrils curling up along its edges.
