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 (200ice caps and Greenland and Antarctic Ice Sheets from Chapter 4; continental heat content from Beltrami et al.

4) The permafrost, like the ice shelves, is buffered from temperature changes by arctic sea ice.

I've been told by a friend that James Hansen once said that albedo changes from melting the arctic sea ice would capture as much additional heat as doubling CO2.

How would an ice - free arctic change the picture?

Observed arctic sea ice reductions can be simulated fairly well in models driven by historical circulation and temperature changes.

Here's my uneducated question — while I respect Gavin's comments about not abusing the science, it seems to me that many measurable indicators of climate change are (to the extent I can tell) occurring / progressing / worsening faster than predicted by most models, whether we're talking about atmospheric CO2 levels, arctic ice melting, glacial retreat, etc..

This idea of volcanoes instead of atmpospheric changes causing the arctic ice to melt was a rumor started by people like Rush Limbaugh, and was immediately debunked by several Dot Earth posters.

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.

Like the ice free arctic, there is not a single thing we can do to change this cycle.

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.

I think there is evidence that AGW has caused the decline in arctic sea ice, which may be responsible for the changes seen in the paths of the jet stream, which may be responsible for the blocking high over Greenland which was responsible for Sandy's left turn.

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 period.

I would say that's weather not climate change but I already got the lecture on how global warming causes freezing in the prairies by disrupting wind patterns so more cold air gets drawn down from the arctic warming it more so ice melts more, or some such folderol.

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.

The catastrophic loss of sea - ice in the arctic (as shown in the graph at the right) is one of the most conspicuous signs that climate change is very real and is happening, not in a hundred or two hundred years, but NOW.

If the arctic ice is melting how can we not be concerned about climate change?

[In reply to Dr. Brooks, the author agreed that the recent rise in arctic temperatures was far too large to be attributed to change of CO,; he thought that the latter might act as a promotor to start a series of imminent changes in the northern ice conditions.

Meier emphasized that the state of arctic sea ice has changed dramatically.

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).

Yet funny how that can't be contemplated: but a far more geologically radical alteration in arctic ice extent from a larger increase in arctic temperature changes and other factors, is so easily perceived and, taken as truth, even.

The goal of the Sea Ice Outlook effort is to synthesize and integrate different observation and modeling efforts and to provide a broad - based assessment of arctic sea ice chanIce Outlook effort is to synthesize and integrate different observation and modeling efforts and to provide a broad - based assessment of arctic sea ice chanice change.

These are radical changes that require increased communication within the arctic science community to advance timely understanding of the arctic sea ice system.

That the last little bit of ice in the arctic is melting, an ice sheet that once covered huge swaths of North America as far south as the US Rockies, upper Midwest and all of New England, is hardly proof that humans are changing the climate.

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.
