areas of Arctic sea ice melt that are larger than Norway, Sweden and Denmark …Arctic ice is thicker, and stays frozen longer during summer In winter, the sea ice covers up to 15 million square kilometers 6 million square miles , and 7 million square kilometers remain atMore than half of the Arctic Ocean was covered in year round ice in the mid 1980s Today, the ice cap is much smaller Alarming evidence of this warming trend was released last week when the U S National Aeronautics and Space Administration NASA released satellite evidence that perennial Arctic ice cover, as of February, rests on less than 30 percent of the oceanTranscript NARRATOR As summer turns to Fall in the Arctic , the ice cover will shrink to its smallest extent for the year This day is an important

killer whale was found frozen in ice in the north of the bay In 2013, an estimated 17 killer whales were seen swimming in the frigid water, their movements tightly constrained by the drifting pack ice

exploration and Stalin’s “Red Arctic ” propaganda, Russian President Vladimir Putin personally identifies with Russia’s Arctic ambitions and seeks to exploit the Arctic narrative of man conquering nature as a distinctive feature of modern …The climate of the Arctic is characterized by long, cold winters and short, cool summers There is a large amount of variability in climate across the Arctic , but all regions experience extremes of solar radiation in both summer and winter Some parts of the Arctic are covered by ice sea ice , glacial ice , or snow year round, and nearly all parts of the Arctic experience long periods withClaim Ice in the arctic , Greenland and Antarctic is melting at an alarming rate Fact Check The polar and glacial ice varies with multidecadal cycles in ocean

variety of public services throughout Alaska In addition to providing the Alaska Public Media program service to Southeast Alaska, KTOO TV operates a …Trends in sea ice thickness volume are another important indicator of Arctic climate change While sea ice thickness observations are sparse, here we utilize the ocean and sea ice model, PIOMAS Zhang and Rothrock, 2003 , to visualize March sea ice thickness from 1979 to 2022 Sea ice less than 1 5 meters is masked out black to emphasize theIntroduction The Greenland ice sheet covers 1 63 million km 2 and contains ice equivalent to 7 4 m of eustatic sea level rise Morlighem et al 2017 Following decades of relative stability, the ice sheet has now lost mass almost every year since 1998, with tied years of record ice loss in 2012 and 2019 Mankoff et al 2022 Ice loss isThe ice then begins expanding again The extent of area covered by Arctic sea ice is an important indicator of changes in global climate because warmer air and water temperatures are reducing the amount of sea ice present Because sea ice is light colored, it reflects more sunlight solar energy back to space than liquid water, thereby playingThe Arctic is a pillar

a new trade route—a Northwest Passage connecting Europe to Asia bypassing both the Panama and Suez canals An ice free Arctic also opens up possibilities for drilling for oil and gas In certain regions of the Antarctic, sea ice cover is actually growing But, overall the land and fresh water based iceArctic Melt Season Lengthens April 1, 2014 A new study by researchers from the National Snow and Ice Data Center NSIDC and NASA shows that the length of the melt season for Arctic sea ice is growing by several days each decade An earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation inThis fact is important, as many people are embracing the myth that the ice sheets are disappearing threatening polar bear populations Ironically, growing ice slowly kills them melting ice brings them a thanksgiving bounty So, if thickening ice isn t helping the polar bear population, what other myths is the media broadcasting to a busyU S Rep Gary Palmer, R

appears to have reached its annual maximum extent The image above shows the ice extent—defined as the total area in which the ice concentration is at least 15 percent—at its 2022 maximum, which occurred on February 25, tying with 2015 for the third earliest maximum on recordOur project, quot NNA Track 1 Arctic impacts and reverberations of expanding global maritime trade routes, quot funded

determined the changes in trans Arctic routes from 1979 to 2019 by combining two harmonized high quality daily sea ice products We found that the trans Arctic routes are becoming navigable much faster than projected by the GCMs The navigation season for open water OW vessels along the Northeast Passage NEP has lengthenedSince sea ice is not studied very well in comparison to Arctic ice , it is less accessible Measurements of sea ice Extent The Extent The Antarctic sea ice cover is highly seasonal, with very little ice in the austral summer, expanding to an area roughly equal to that of
