Document Summary
Ipcc assessments and projections of 2007 were far off from the models and projections one far off predication was the artic sea ice melt. Ipcc predicted no sea ice by end of century of artic this could happen within the next decade. Max sea ice melt is getting smaller and smaller every year. This year had more ice than last year. 2012 smashed record of 2007 of max sea ice melt (2007 also smashed previous record of melt) Smaller ice surfaces mean more dark surfaces exposed to absorption. Artic ice is quarter of it was 30 years ago. Expansions and contraction of ice is artic is important in ocean"s surface currents and volume. Climate change is happening very fast in the artic and indigenous/inuit"s people have been seeing changes for decades. Their culture is refined to knowledge of water and ice. Average world surface temperature is 0. 8c from warmer pre-industrial temperatures and it is double in the artic.
