This eye-opening animation shows the dynamics of the ozone layer from January 1st to March 23rd in both 2010 and 2011. Recent observations from satellites and ground stations suggest that atmospheric ozone levels for March 2011 in the Arctic were approaching the lowest levels in the modern instrumental era.

Historically, every time carbon dioxide levels increase in Earth’s atmosphere, the average surface temperature increases, ice melts, and the seas rise.
