I blog about environmental and social justice issues because I am very concerned about the health of the interdependent web of life of which we are a part.

Arctic Sea Ice Loss

The Arctic is locked into a destructive cycle that could see its icy cover rapidly disappear, scientists have confirmed. A new analysis shows that dwindling levels of sea ice are responsible for unusual levels of global warming in the region. The findings reinforce suggestions that a positive feedback between ice loss and temperature rise has emerged in the Arctic, which increases the chances of further rapid ice loss and warming.....Temperatures in the Arctic have risen twice as fast as the rest of the world in recent decades, a phenomena known as Arctic amplification. Scientists have long suspected that loss of sea ice was responsible, but other factors such as changes in wind, clouds and ocean currents have also been blamed.
The more the polar ice melts, the less heat is reflected from those white polar caps.  Open water absorbs more heat..... and the melting continues.  It must be getting harder and harder for deniers to find any evidence.
