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.
