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:
“Certainly parents play a crucial role in the lives of individuals who are intellectually gifted or creatively talented. But this role is not one of active instruction, of teaching children skills,... rather, it is support and encouragement parents give children and the intellectual climate that they create in the home which seem to be the critical factors.”
—David Elkind (20th century)
“A good customer should not change his shop, nor a good shop change its customers.”
—Chinese proverb.
“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)
