Sentences with phrase «arctic ice retreat»

Not exact matches

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.

For other indicators — glacial retreat, sea level, arctic ice extent, etc. — the data is equally noisy, and it is difficult having a sensible discussion without the inevitable cherry - picking on both sides of the argument.

I am very well aware and have previously blogged that there are multiple factors that determine the degree of ice lost any given year — but the literature is clear that even in 2007, global warming played «a large part» (see «What drove the dramatic retreat of arctic sea ice during summer 2007?

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..

Zhang, J., R. Lindsay, M. Steele, and A. Schweiger (2008), What drove the dramatic retreat of arctic sea ice during summer 2007?

The latest movie movie (5) shows the rapid retreat of arctic sea ice in summer 2007 and 2008.

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).

Below are examples of photos show the strongest and most obvious result of global warming; retreating glaciers, melting ice and shrinking snow cover occurring in the arctic region of the world.

Furthermore you use that interpretation to push the claim that temperatures for most of the holocene were warming than now which can hardly be supported by evidence of say arctic ice extent, glacial retreat levels etc, never mind other proxies.

It is not just data from climate models predicting what will happen; now there is evidence of the warming which has already occurred: massive ice melting in Greenland, rising sea levels and retreating arctic ice, record droughts, etc..

Zhang, J., M. Steele, and R. Woodgate, The role of Pacific water in the dramatic retreat of arctic sea ice during summer 2007, J. Polar Science, 19 (2), 93 - 107, 2008.

When the oceans are cold and the arctic is closed it snows less and the ice retreats where ever it needs to allow the earth to warm.

When I started looking at this topic the first thing that struck me was just how much time is spent in the blogosphere debating the effects (real or imagined) of global temperature rise and how little time seemed to be spent on the key evidential science; as though retreating glaciers, arctic sea - ice or coral bleaching said anything about causality.
