Climate Change In The Arctic
Ongoing changes in the climate of the Arctic include rising temperatures, loss of sea ice, and melting of the Greenland ice sheet. The Arctic ocean will likely be free of summer sea ice before the year 2100. Projections as to when precisely this will occur vary between the years 2060–2080, 2030, and 2016. Because of the amplified response of the Arctic to global warming, it is often seen as a high-sensitivity indicator of climate change. Scientists also point to the potential for release of methane from the Arctic region, especially through the thawing of permafrost and methane clathrates. Arctic climate changes are summarized in the IPCC Fourth Assessment Report and the Arctic Climate Impact Assessment.
The National Oceanic and Atmospheric Administration (NOAA)'s Arctic Report Card presents annually updated, peer-reviewed information on recent observations of environmental conditions in the Arctic relative to historical records.

Famous quotes containing the words climate, change and/or arctic:
“Russian forests crash down under the axe, billions of trees are dying, the habitations of animals and birds are layed waste, rivers grow shallow and dry up, marvelous landscapes are disappearing forever.... Man is endowed with creativity in order to multiply that which has been given him; he has not created, but destroyed. There are fewer and fewer forests, rivers are drying up, wildlife has become extinct, the climate is ruined, and the earth is becoming ever poorer and uglier.”
—Anton Pavlovich Chekhov (1860–1904)
“That those tribes [the Sac and Fox Indians] cannot exist surrounded by our settlements and in continual contact with our citizens is certain. They have neither the intelligence, the industry, the moral habits, nor the desire of improvement which are essential to any favorable change in their condition.”
—Andrew Jackson (1767–1845)
“Does the first wild-goose care
whether the others follow or not?
I don’t think so he is so happy to be off
he knows where he is going
so we must be drawn or we must fly,
like the snow-geese of the Arctic circle.”
—Hilda Doolittle (1886–1961)
