Arctic Death Spiral

A good pictorial representation of the Arctic Death Spiral

Arctic Death Spiral - Evolution to July 2013


13 August, 2013



The video below is a visualization of the Arctic Death Spiral showing the evolution of the volume of sea-ice over time from 1979 to July 2013. The rate of ice loss in the Arctic is staggering. Since 1979, the volume of Summer Arctic sea ice has declined by more than 80% and is accelerating faster than scientists believed it would, or even could melt.

Pitch of the notes are proportional to the average sea-ice volume for each month. Spectral filters are derived from the average sea-ice volume for each year. Produced using Perl and PovRay, Midi perl and Reason and Virtualdub on a cluster of Linux servers.
