The Greenland ice cap is melting. Yesterday I hiked in a parka until it go too hot and walked in a t shirt. The mosquitos are ferocious; a recent phenomenon. Before, Greenland was too cold to harbor a mosquito population. Now, there is no native bird population to keep the mosquitos down. Lakes like this are forming on top of the ice cap. One way or another, the melting waters of Greenland are finding their way to the sea.
