After studying pictures taken by the drones, the scientists came to the conclusion that the dark zone in the Greenland ice is becoming more and darker. The specialists was better able to figure out why this is happening and suggest what can cause this trend.
As it turned out, in the area where the ice is much darker than usual, there is a large amount of dust and soot, however, the ice rapidly changes the hue not directly because of them and because of the algae that dust and carbon feed.
When the ice gets darker, it starts worse than reflect light, more heat and, consequently, faster to melt. In turn, increasing the amount of liquid water facilitates further the spread of the dark algae, which stain may become darker and broader. Thus, the situation with melting of glaciers because of these dark spots over time becomes only more serious.
The consequences of thawing permafrost, according to scientists, can affect the entire planet, especially coastal regions of every continent. Now sea levels are rising about three millimeters a year, but the rate of growth gradually accelerated.
Scientific work was published in the journal Nature Communications.
Previously, other studies have shown that as a result of melting glaciers, many coastal cities and Islands can be under water. Among other consequences of a variety of professionals referred to as hurricanes and tsunamis, as well as getting into the water and atmosphere of mercury, today “locked” in permafrost.
That algae greatly accelerate the melting of glaciers, scientists said earlier. In particular, it was dedicated to the research of experts from the Helmholtz Center in Potsdam, published in the middle of last year. Then the focus of the scientists were algae of the red and pink colors, but the conclusions were broadly similar.
