[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.

In the case of Arctic whales, the changes in
sea ice might benefit their populations, at least in the short term: the loss and
earlier retreat of
sea ice opens up new habitats and, in some areas of the Arctic, has also led to an increase in food production and the length of their feeding season.
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 shelv

These include increases in heavy downpours, rising temperature and
sea level, rapidly
retreating glaciers, thawing permafrost, lengthening growing seasons, lengthening
ice - free seasons in the ocean and on lakes and rivers,
earlier snowmelt, and alterations in river flows.
I also think that proof coming from Arctic
sea ice, glacier
retreats, etc. might be indications, but are just one step away from the cherry blossoms blooming
early, the 26 + storms we had in 2005, Ted Turner's statement, «it's hotter than hell outside», etc. «proofs» that are thrown out by some.
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.
I believe that what the phrase is trying to get at is either the acceleration relative to the pause in the 1950 - 1970 period, or the acceleration in accumulation of noticeable consequences — worldwide glacier melt,
sea ice retreat,
earlier onset of springtime, (possibly) increasingly intense hurricanes, Larsen - B breakup, melting of Greenland along the margins, etc..
By analyzing climate anomalies in the model that are similar to those that occurred in the
early twentieth century, it was found that the simulated temperature increase in the Arctic was related to enhanced wind - driven oceanic inflow into the Barents
Sea with an associated sea ice retre
Sea with an associated

sea ice retreat.
Among these physical changes are increases in heavy downpours, rising temperature and
sea level, rapidly
retreating glaciers, thawing permafrost, lengthening growing seasons, lengthening
ice - free seasons in the oceans and on lakes and rivers,
earlier snowmelt and alterations in river flows.
Since 2000, the science has steadily pointed to the ever - growing summertime
retreat of Arctic
sea ice as an
early indicator of human - driven warming.
Sea ice this year is melting at a pace two to four weeks faster than normal as pulses of warm air have been streaming into the Arctic from eastern Siberia and northern Europe and sea ice has retreated early from the Beaufort S
Sea ice this year is melting at a pace two to four weeks faster than normal as pulses of warm air have been streaming into the Arctic from eastern Siberia and northern Europe and

sea ice has
retreated early from the Beaufort
SeaSea.
We do not know much about
earlier cycles of warming / cooling and
sea ice retreat / expansion.
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...
Ice retreat depends strongly on the amount of solar heating of the surface ice and ocean; clear sky conditions early in the melt season can go a long ways towards helping ice retreat later in the season, so this is one of the variables that will be monitored closely (e.g., in the Barrow coastal sea ice break - up forecast, see belo

Rapid
retreat of the
ice cover in the Kara
Sea and
early melt out of Hudson Bay contributed to this new record low.
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.
Seasonal

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.
However, the accelerated
retreat of glaciers, combined with greater melting of these
ice sheets, suggest that
earlier projections of
sea - level rise over the next century — such as in the 2007 report of the Intergovernmental Panel on Climate Change — are conservative.8, 9
At the same time, substantial and
early ice retreat in the Kara
Sea (see contribution by Gerland et al., below) has resulted in favorable shipping conditions along the Northern
Sea Route (NSR).
Earlier this year, climate scientist Marco Tedesco of Columbia University published data supporting an earlier proposal that the retreat of Arctic sea ice has disrupted the polar jet stream, causing weather systems to meander more slowly from west t
