Recent mapping and a figure showing Arctic sea ice extent by the NSIDC
indicate a sharp turn to slower growth (almost flat), which fits with
a discussion given in a recent (Nov. 10) article by NSDIC:
"Arctic sea ice and climate are behaving in ways not seen before in
the satellite record both in the rate and extent of ice loss during
the spring and summer, and in the record ice growth rates and
increased Arctic air heating during the fall and winter."
That "sea ice and climate are behaving in ways not seen before in the
satellite record" is alarming many scientists.
Also in the NSDIC article:
"In the past five years, the Arctic has shown a pattern of strong
low-level atmospheric warming over the Arctic Ocean in autumn because
of heat loss from the ocean back to the atmosphere. Climate models
project that this atmospheric warming, known as Arctic amplification,
will become more prominent in coming decades and extend into the
winter season. As larger expanses of open water are left at the end of
each melt season, the ocean will continue to hand off heat to the
Who is not alarmed by these turn in events???
