The report, sponsored by the federal National Oceanic and Atmospheric Administration,
found unprecedented temperatures this year in the Arctic contributed to a record - breaking delay in the annual freeze — prompting extensive melting of the Greenland ice sheet and land - based snow cover.
Kaitlin Keegan, of Dartmouth College in the US, and colleagues report in the Proceedings of the National Academy of Sciences that the dramatic surface melting of the island's ice sheet in 2012 can be explained by a combination of
unprecedented temperatures linked to climate change and clouds of ash and soot from forest fires.
«Russell Brice, head of the leading Everest climbing operation Himalayan Experience, announced that he would pull his team off Everest,
citing unprecedented temperatures that made climbing too dangerous.
Scientists worldwide noted that Soon's methodology was grossly oversimplified, ignoring key factors that scientists have warned will lead to
unprecedented temperature increases in the coming decades.
Moving on in an article that seems less and less about the North Pole and more and more about Dr. James Hansen's imagined offenses, Goddard rants: «Dr Hansen also talks frequently about
the unprecedented temperature rise in the Arctic, yet his own temperature records show that much of the Arctic (including Greenland) was warmer from 1920 - 1940 than now.»
I am following this discussion with interest, since the question of whether the last 30 years or so represent
an unprecedented temperature variation is a critical one for AGW.
«
Unprecedented temperatures and a... decrease in productivity can be attributed to (human)... global warming.»
The two factors would this time work together to heat the Earth's climate to
unprecedented temperatures.
The unprecedented temperatures for humankind will hit them first through no fault of their own.
