2014 NAP Linkages Between Arctic Warming and Mid-Latitude Weather Patterns: Summary of a Workshop 2013

March 2014 J. Stroeve New data confirms Arctic ice trends: Ice-free season getting longer by five days per decade. The amounts of energy involved is equivalent to several times the energy released by the atom bomb at Hiroshima for every square kilometre of the Arctic ocean.

2013 Trend shows average albedo iof sea ice, is declining in all summer months (May-August).

2013 retreat of sea ice is diminishing Earth's albedo, or reflectivity, considerably faster than previously estimated

The loss of thick old ice results in less abedo from the new thinner ice cover. Albedo evolution of seasonal Arctic sea ice 2012.

The loss of Arctic summer sea ice is accelerating, and the perennial sea ice loss is increasing.

The big burning questions on the loss of Arctic summer sea ice albedo are:
  (1) How much will this increase the rate of warming?
  (2) What will the impacts be?

There is little published science to answer these vital questions. Research by David Lawrence  (NCAR) tells us that the summer sea ice loss would increase the rate of warming of the whole Arctic region more than three and half times.

Though scientists say the Arctic summer sea ice is the air conditioner of the entire northern hemisphere and the climate of the hemisphere will be changed, there is nothing to tell us how and by how much.
