Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Northern Hemisphere Ice Cover Continues Shrinking

The Arctic Sea Ice Extent shrank to 3.46 million square kilometers (3,456,695.22 km²) on September 12, 2012, according to National Snow and Ice Data Center (NSIDC).

Original Caption: The total area of sea ice is the sum of First Year Ice (FYI), Multi Year Ice (MYI) and the area of ambiguous ice types, from the OSISAF ice type product. However, the total estimated ice area is underestimated due to unclassified coastal regions where mixed land/sea pixels confuse the applied ice type algorithm. The shown sea ice extent values are therefore recommended be used qualitatively in relation to ice extent values from other years shown in the figure. In late 2012 sea ice climatology and anomaly data will be available here.

Northern Hemisphere Ice Cover falls below 3.6 million km² —FIRE-EARTH 

As of September 5, 2011, the Arctic sea ice extent (ASIE) was 3,686,199.43 km² according to NSIDC.

  • Daily average ice melt for September currently stands at more than 87,000 km², NSIDC data shows.

Arctic sea ice extent fell below 3.6 million square kilometers (1.39 million square miles) on September 6, 2012, FIRE-EARTH estimates.

FEWW model shows the Arctic sea ice extent could fall to about 3 million km² (1.15 million square miles) during the 2012 melt season with a probability of 0.5 [P = 54%]

Northern Hemisphere Sea Ice Cover Shrinking Rapidly

Arctic sea ice extent shrank to about 3.65 million square kilometers (1.41 million square miles) on September 2, 2012, FIRE-EARTH estimates.

FEWW model shows the Arctic sea ice extent could fall to about 3 million km² (1.15 million square miles) during the 2012 melt season with a probability of 0.5 [P = 54%]

The ice extent values are calculated from the ice type data from the Ocean and Sea Ice, Satellite Application Facility (OSISAF), where areas with ice concentration higher than 30% are classified as ice.        The total area of sea ice is the sum of First Year Ice (FYI), Multi Year Ice (MYI) and the area of ambiguous ice types, from the OSISAF ice type product. However, the total estimated ice area is underestimated due to unclassified coastal regions where mixed land/sea pixels confuse the applied ice type algorithm.
