Sentences with phrase «ice retreats earlier»

[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.

Not exact matches

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 shelves.

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..

Igor Polyakov of the University of Alaska, Fairbanks, who has studied an Arctic warm spell in the early part of the 20th century, says the new ice retreat is almost assuredly more dramatic than anything seen back then.

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 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.

In an email message earlier this month, Dr. Rigor confirmed that this appeared to be playing out as predicted and projected a couple of summer seasons with less substantial ice retreats:

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.

The Competitive Enterprise Institute, which is fighting hard against treaties or legislation limiting greenhouse gases, has pointed afresh to old media coverage pointing to «unprecedented» Arctic ice retreats and warming early in the 20th century.

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 Sea.

With lack of multiyear ice, a normal or slightly below - normal thickness offshore ice cover (based on ice thickness flights earlier in the season) and coastal ice vulnerable to early break - up, ice conditions would favor a normal or somewhat early seasonal ice retreat.

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...

Carved by earlier advances of ice during colder periods, the troughs enable warm, salty water to reach the undersides of glaciers, fueling their increasingly rapid retreat.

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 beloIce 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 beloice 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 beloice 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 beloice break - up forecast, see below).

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 sea ice retreat in 2012 began with a major reduction event in early June (Figure 2) associated with persistent high pressure over the Beaufort Sea and low pressure over the Kara Sea, now referred to as the Arctic Dipole (AD) weather pattern (see discussion of the AD in previous Outlooks).

When seasonal ice retreat occurs early, low - albedo open water areas are exposed early, which gain a lot of energy from the sun.

Current south Greenland ice margin retreat suggests that south Greenland may have now warmed to or above earliest Holocene summer temperatures.

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.

Early Holocene summer warmth drove dramatic Greenland ice sheet (GIS) retreat.

Fowler, Drobot, and Maslanik (4 - no new data available - see June report) While no new data are available for the onset of ice retreat from Fowler et al., their earlier assessment of ice retreat patterns in this sector is still valid and appears to reproduce at least part of the retreat pattern, with a tongue of lingering ice north of Barrow.

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).
