Arctic sea ice area reached a record low of 2.87746 million square km on the 230th day of 2012, as illustrated on the image below by The Cryosphere Today. Below the sea surface temperature anomaly for August 20, 2012, by the National Oceanic and Atmospheric Administration (NOAA). Rising temperatures in the Arctic threaten to trigger methane releases, as shown on the poster below. The poster forms part of the updated presentation Why act now, and how?
