Dark Ice in Greenland

A new variable has recently been added to the complex array of variables that relate to climate change.  This BBC report refers to new research about the darkening of the Greenland Icesheet due to the growth of algae and micro-organisms. As the icesheet darkens in colour (‘dark ice’) due to these blooms, it absorbs more of the sun’s radiation and thus accelerates the melting of the ice with the knock on effect of accelerating the contribution of the Greenland ice to rising sea levels.
