Sentences with phrase «sea ice changes»

Ensemble decadal prediction simulations using the Community Earth System Model (CESM) can skillfully predict past decadal rates of Atlantic winter sea ice change because they do well at predicting THC - driven ocean heat content change in the vicinity of the winter sea ice edge in the Labrador, Greenland, Irminger, and Barents Seas.
Satellites from NASA and other agencies have been tracking sea ice changes since 1979, and the data show that Arctic sea ice has been shrinking at an average rate of about 20,500 square miles (53,100 square kilometers) per year over the 1979 - 2015 period.
Polyak et al. (2010) looked at Arctic sea ice changes throughout geologic history and noted that the current rate of loss appears to be more rapid than natural variability can account for in the historical record.

I believe that the «enourmous» energy accumulation once converted into temperature anomaly not only doesn't explain the variation between hemisphere sea ice changes, it also doesn't explain the «unprecidented» Arctic melt or the two points 2013 and 2014 that are missing from your frigthening graphic.
The goal of the Sea Ice Outlook effort is to synthesize and integrate different observation and modeling efforts and to provide a broad - based assessment of arctic sea ice change.
The loss of sea ice changes ecosystems, opening the door to invasive species, and alters habitat and plankton blooms, affecting Alaska's commercial fishing industry, which leads the United States in the value of its catch.
Observed hemispheric asymmetry in global sea ice changes.
Ice sheets can take centuries to millennia to melt or form, whereas sea ice changes occur much more rapidly (as we're currently seeing in the Arctic).
Their model - based estimate of the effect of sea ice changes appears to be ~ 4 %, the difference between the 9 percentage points bias due to blending and the 5 percentage points (per Cowtan et al. 2015) due purely to the use of SST rather than tas for the open ocean.
This is largely because melting sea ice changes the albedo of high latitude oceans, and to a lesser extent because an inversion prevails at high latitudes, especially in winter, whereas at low latitudes the heating is convectively mixed througout the troposphere.
Feedback factors calculated for these processes, with atmospheric dynamical feedbacks implicitly incorporated, are respectively fwater vapor ∼ 1 - 6, fclouds ∼ 1.3 and fsnow / ice ∼ 1.1, with the latter mainly caused by sea ice changes.
It appears that Antarctic sea ice changes in steps and that the current period is one of relative stability.
Regions of rapid sea ice change: An inter-hemispheric seasonal comparison.
A new paper that combines paleoclimatology data for the last 56 million years with molecular genetic evidence concludes there were no biological extinctions [of Arctic marine animals] over the last 1.5 M years despite profound Arctic sea ice changes that included ice - free summers: polar bears, seals, walrus and other species successfully adapted to habitat changes that exceeded those predicted by USGS and US Fish and Wildlife polar bear biologists over the next 100 years.
MacKinnon says the lack of sea ice changes the dynamics of that process by enabling the ocean to absorb more heat, creating a positive - feedback loop that begets more rapid sea ice melting.
Temperature and sea ice changes in the Arctic can affect wildlife and open up new areas for oil drilling and shipping — both industries that can have heavy climate impacts.
The paper, to appear Sept. 14 in The Cryosphere, is the first to quantify the sea ice changes in each polar bear subpopulation across the entire Arctic region using metrics that are specifically relevant to polar bear biology.
The research concludes that for other changes, such as regional warming and sea ice changes, the observations over the satellite - era since 1979 are not yet long enough for the signal of human - induced climate change to be clearly separated from the strong natural variability in the region
The team found that sea ice changes can lead to convection changes over the tropical Pacific.
It's just anecdotal, but as I was scraping the klister off my skis it planted the idea in my mind to figure out a way to see if the European arctic warming trend could be attributed to sea ice changes and other anthropogenic effects.
Sea ice changes this year were again very dramatic, with the Arctic September minimum destroying the previous records in all the data products.
