Since IPCC (2001) the cryosphere has undergone significant changes, such as the substantial retreat of arctic sea ice, especially in summer; the continued shrinking of mountain glaciers; the decrease in the extent of snow cover and seasonally frozen ground, particularly in spring; the earlier breakup of river and lake ice; and widespread thinning of antarctic ice shelves along the Amundsen Sea coast, indicating increased basal melting due to increased ocean heat fluxes in the cavities below the ice shelves.

The ocean heat content change is from this section and Levitus et al. (2005c); glaciers, ice caps and Greenland and Antarctic Ice Sheets from Chapter 4; continental heat content from Beltrami et al. (2002); atmospheric energy content based on Trenberth et al. (2001); and arctic sea ice release from Hilmer and Lemke (2000).

Karl Schroeder: If there is any life on Earth in 100 years, I foresee either an ecological catastrophe, with the majority of species extinct, the oceans stagnant, the arctic and Antarctic desolate and lifeless, and billions of people living in complete ignorance of how things could be, in massive urban centres; or, a world in which climate change was solved early and completely through innovations in power generation and carbon sequestration, where agriculture has gone to vertical farming and North America has largely been rewilded back to forest and open prairie, and where extinct species are regularly recreated by genetic engineering and reintroduced.

The rise of CO2 from 270ppm to now over 400ppm, the extent of equatorial and sub tropical deforestation, the soot deposits on the polar ice caps, the increase in atmospheric water vapour due to a corresponding increase in ocean temps and changes in ocean currents, the extreme ice albedo currently happening in the arctic etc, etc are all conspiring in tandem to alter the climate as we know it.

1) It seems to me that the key mechanism for any impact must be the changes that increased arctic ocean temperatures will impose on the atmospheric circulation feature known as the Polar Cell, and via this on the Ferrel cell which sits over the mid latitudes.

Chris V. CO2 goes up, temp goes down, oceans cool, sea levels decrease, arctic sea ice is within 1979 -2000 mean, AGW theory of catastrophic warming is B U S T... Even the fraudulent manipulation of the GISS data set does not change that.

GOAL 1: Examine the historical evolution of the arctic ice - ocean system from 1948 to 2003 to understand the large - scale changes that have occurred in sea ice and the upper Arctic Ocean over this time peocean system from 1948 to 2003 to understand the large - scale changes that have occurred in sea ice and the upper Arctic Ocean over this time peOcean over this time period.

The project will also analyze changes in oceanic circulation and processes in an ice - depleted Arctic Ocean, and in its interactions with the sub arctic oceans.

And remember, the satellite data are one small part of a vast amount of data that overwhelmingly show our planet is warming up: retreating glaciers, huge amounts of ice melting at both poles, the «death spiral» of arctic ice every year at the summer minimum over time, earlier annual starts of warm weather and later starts of cold weather, warming oceans, rising sea levels, ocean acidification, more extreme weather, changing weather patterns overall, earlier snow melts, and lower snow cover in the spring...

THERE HAS BEEN A WARMING TREND FROM THE 70s THRU THE LATE 90s,... accompanied by other changes tied to a warming trend (record low arctic sea ice extent & thickness, retreating glaciers, retreating snow lines, warming ocean surface temps, increases in sea height, de-alkalinizing oceans).

The arctic temperatures and arctic ice extent varies in a very predictable 60 - 70 year cycle that relates to ocean cycles which are likely driven by solar changes.

A different understanding doesn't stop melting in the arctic, droughts, shifting climate zones, increased ocean temps and sea level rise or the need to anticipate changes these realities will FORCE on society, changes that can't be made quickly.

As for your V&V discussion, I don't see the relevance of it in this talk, but in the context of physical science of climate change we have overwhelming evidence of model usefulness and verification (water vapor feedback, simulating the Pinatubo eruption effects, ocean heat content changes, stratospheric cooling, arctic amplification, etc).

These processes include arctic clouds and their radiative impacts, sea - ice albedo changes, surface energy fluxes, vertical momentum transfer, and ocean vertical heat transport.

MODELING OF FUTURE ARCTIC SEA ICE CHANGE «Given the estimated trend and the volume estimate for October — November of 2007 at less than 9,000 km3 (Kwok et al. 2009), one can project that at this rate it would take only 9 more years or until 2016 ± 3 years to reach a nearly ice - free Arctic Ocean in summer.»

An integrated ice - atmosphere - ocean monitoring and forecasting system designed for observing, understanding, and quantifying arctic climate changes http://www.damocles-eu.org/

The report, the most precise yet thanks to advances in scientific monitoring, confirms that climate change impacts are outpacing previous projections for ocean warming, the rate of glacial ice melt in the arctic, and sea level rise.

The ocean heat content change is from this section and Levitus et al. (2005c); glaciers, ice caps and Greenland and Antarctic Ice Sheets from Chapter 4; continental heat content from Beltrami et al. (2002); atmospheric energy content based on Trenberth et al. (2001); and arctic sea ice release from Hilmer and Lemke (2000).
