NOAA has a nice visual of the
recession of the Jakobshavn
glacier which RC posted here: http://www.realclimate.org/images/jakobshavn.jpg There was a rather large retreat from 1851 until 1913, then slowing until 2001,
with a recent acceleration.
The impacts of this recent regional rapid warming around the Antarctic Peninsula have been dramatic,
with the collapse of ice shelves [14], and
with 87 % of
glaciers in
recession [15].
(4) Norway's
glaciers are currently more advanced than nearly all of the last 10,000 years,
with pronounced
recession occurring during the 1800s.
Most (about 2/3) of the recent
recession of the
glacier occurred between 1860 and 1957 and can not be ascribed to the anthropic emissions of CO2 which were then insignificant: 0,083 Gt - C in 1859, 1,3 Gt - C in 1940 and 2,2 Gt - C in 1956
with an assumed CO2 content of the air - from Law Dome ice core - of 286 ppm in 1859, 310 ppm in 1940 and 314 ppm in 1956.
In the case of a
recession there is a shared signal, just as
with global warming there is a shared signal amongst Greenland
glaciers.
Nevertheless, the fast
glacier recession in the tropics seems at first sight to be consistent
with an increase in tropical freezing heights of 100 m over the period 1970 to 1986 as reported by Diaz and Graham (1996), corresponding to an increase of 0.5 °C at tropical high mountain levels, which they also link to increases in tropical SST since the mid-1970s (Figure 2.10).
