Not exact matches

Retreating sea ice in the Iceland and Greenland Seas may be changing the circulation of warm and cold water in the Atlantic Ocean, and could ultimately impact the climate in Europe, says a new study by an atmospheric physicist from the University of Toronto Mississauga (UTM) and his colleagues in Great Britain, Norway and the United States.

A new model, investigating the retreat of this ice sheet and its many impacts has just been published in Quaternary Science Reviews.

We determine that this difference is driven by the growth and retreat of large continental ice sheets that are present in the cold ice - age climates; these ice sheets reflect a lot of sunlight and their growth consequently amplifies the impact of CO2 changes.»

The winds and currents will have an even greater impact as the ice retreats from open areas near the North Atlantic towards the Canadian islands.

[Aug. 9, 8:04 p.m. Updated Joe Romm has predictably assailed my view of Arctic sea ice trends and their implications, straying into discussions of melting permafrost (which is an entirely different issue laden with its own questions — one being why the last big retreat of permafrost, in the Holocene's warmest stretch, didn't have a greenhouse - gas impact) and my refusal to proclaim a magically safe level of carbon dioxide (which I discuss here).

Fourteen research teams studying the impacts of warming on the Arctic Ocean have issued independent projections of how the sea ice will behave this summer, and 11 of them foresee an ice retreat at least as extraordinary as last year's or even more dramatic.

Somewhat off - topic, but Antarctica Glacier Retreat [should read: Antarctic Penninsula ice shelf collapse] Creates New Carbon Dioxide Store; Has Beneficial Impact On Climate Change http://www.sciencedaily.com/releases/2009/11/091109121117.htm

Joe Romm has predictably assailed my rejection of his «death spiral» depiction of Arctic sea ice trends, straying into discussions of melting permafrost (which is an entirely different issue laden with its own questions — one being why the last big retreat of permafrost, in the Holocene's warmest stretch, didn't have a greenhouse - gas impact) and my refusal to proclaim a magically safe level of carbon dioxide (which I discuss here).

A quantification of the impacts of deforestation and the continuing retreat of the ice sheets should be included in the consideration of the debate.

In addition to direct MYI melt due to high - latitude warming, the impact of enhanced upper - ocean solar heating through numerous leads in decaying Arctic ice cover and consequent ice bottom melting has resulted in an accelerated rate of sea - ice retreat via a positive ice - albedo feedback mechanism.

The albedo change resulting from the snowline retreat on land is similarly large as the retreat of sea ice, so the combined impact could be well over 2 W / sq m. To put this in context, albedo changes in the Arctic alone could more than double the net radiative forcing resulting from the emissions caused by all people of the world, estimated by the IPCC to be 1.6 W / sq m in 2007 and 2.29 W / sq m in 2013.»

The dramatic retreat of perennial Arctic sea ice has been a wake - up call to the climate community that climate change may not necessarily be slow and steady nor its impacts only of consequence in the far - off future.

«The CCR - II report correctly explains that most of the reports on global warming and its impacts on sea - level rise, ice melts, glacial retreats, impact on crop production, extreme weather events, rainfall changes, etc. have not properly considered factors such as physical impacts of human activities, natural variability in climate, lopsided models used in the prediction of production estimates, etc..

While the climate change signal is much clearer in the northern latitudes - where longer - term records show a relatively steady retreat of Arctic sea ice - evidence of global warming's impact around Antarctica is also showing up in the observations.

While the world is seeing real impacts (from ice retreats to changing weather patterns) from heating, which science links to CO2 (and other) emisssions.

A new model, investigating the retreat of this ice sheet and its many impacts has just been published in Quaternary Science Reviews.

So are most of the other symptoms of climate change, such as Arctic sea ice retreat, in terms of their impact.

Because of its cold - adapted features and rapid warming, climate change impacts on Alaska are already pronounced, including earlier spring snowmelt, reduced sea ice, widespread glacier retreat, warmer permafrost, drier landscapes, and more extensive insect outbreaks and wildfire, as described below.

With participants representing over one dozen academic and governmental research institutions, SEARCH focuses on how retreating sea ice, thawing permafrost, and diminishing land ice are impacting society within and beyond the Arctic.

It will also confirm the accelerated rate of change for impacts such as sea - level rise, the steady retreat of Arctic sea ice and quickened melting of ice sheets and glaciers, as well as offer more detail on scenarios that will shape international negotiations over both short - term and long - term greenhouse gas emissions, including how long «business as usual» can be sustained without dangerous risk.

These results suggest that the tropospheric oxidizing capacity could change dramatically over the Arctic if summer sea ice is to retreat in the future, something that could impact the removal of important gases (methane, carbon monoxide) in this region.
