Not exact matches

The second error is obvious from the fact that the recent warming is seen in the oceans, the atmosphere, in Arctic sea ice retreat, in glacier recession, earlier springs, reduced snow cover etc., so even if all met stations were contaminated (which they aren't), global warming would still be «unequivocal».

«the recent warming is seen in the oceans, the atmosphere, in Arctic sea ice retreat, in glacier recession, earlier springs, reduced snow cover etc...».

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 shelvsea 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 shelvSea coast, indicating increased basal melting due to increased ocean heat fluxes in the cavities below the ice shelves.

Current predictions [5], [6] suggest that trends in sea ice extent will alter in the second half of this century and that the annual average sea ice extent will diminish by 33 %; most of this retreat is expected to occur in winter and spring [5], [6], with attendant risks for emperor penguins.

The second error is obvious from the fact that the recent warming is seen in the oceans, the atmosphere, in Arctic sea ice retreat, in glacier recession, earlier springs, reduced snow cover etc., so even if all met stations were contaminated (which they aren't), global warming would still be «unequivocal».

Qualitative indicators like sea ice coverage, spring thaw dates, and melting permafrost provide strong additional evidence that trends have been positive at middle and high northern latitudes, while glacier retreat suggests warming aloft at lower latitudes.

[UPDATE, 5/20: Natalie Angier has written a nice column on the relatively unheralded walrus, which — like the far more charismatic polar bear — is having a hard time as Arctic sea ice retreats earlier and farther each spring and summer and forms later in the boreal fall.

As noted above, the recent warming «is seen in the oceans, the atmosphere, in Arctic sea ice retreat, in glacier recession, earlier springs, reduced snow cover etc.» Another «inconvenient truth» for denialists to avoid mentioning or acknowledging while overblowing the UHI issue.

As expected from my 2002 paper, the low A.O. conditions of late have sequestered quite a bit of sea ice the Arctic, which should foster a more moderate retreat of sea ice extent this coming spring, summer and fall.

So if you apply a negative sign to the figure at the bottom of / / seaice.apl.washington.edu/AO/, I would expect colder than normal spring especially in the Eurasian Arctic, less retreat of sea ice this summer, then colder than normal this fall in the Eurasian Arctic....

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...

«Mid-latitude economies such as those in Europe and the United States could be threatened, for example, by a suggested link between sea - ice retreat and the strength and position of the jet stream, bringing extreme winter and spring weather,» the paper states.

You can't fake spring coming earlier, or trees growing higher up on mountains, or glaciers retreating for kilometres up valleys, or shrinking ice cover in the Arctic, or birds changing their migration times, or permafrost melting in Alaska, or the tropics expanding, or ice shelves on the Antarctic peninsula breaking up, or peak river flow occurring earlier in summer because of earlier snowmelt, or sea level rising faster and faster, or any of the thousands of similar examples.

Similar sea ice trends and weather conditions were present during the spring seasons preceding past ice shelf retreats (e.g., 2001 to 2002).

They found that 68 percent of the variance in the date that ice retreats from the continental shelf break in the Chukchi Sea in spring can be explained by fluctuations in the April through June Bering Strait oceanic heat inflow.

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.

In an extreme case with Arctic sea ice retreating even in spring, this process could become far less important.
