In this low resolution false color image we can see a green streak of vegetation and what look like glaciers and lakes that have become large enough to become visible at this low resolution. It is not possible for that much rain to come to the Sahara without producing visible results over time.

Here we can see green patches of vegetation. Sometimes water shows up as a greenish color, while colder ice shows up as dark blue, so these might be bodies of water and not ice patches

melting ice 01.Dec.2015 03:22

What seems to be happening here is that melting ice is producing marshy patches of swamp. The water is cold as indicated by the bluish colors
