ice sheet is losing.
«I thought this idea of growing a massive star in a special configuration and forming a black hole with the right kind of
masses was something we could approximate, but to
see the black hole inducing star formation and driving the dynamics in ways that we've observed in nature was really
icing on the cake.»
The Gravity Recovery and Climate Experiment (GRACE), the satellites tasked with measuring the
mass changes in Greenland and other icy landscapes around the world, has a hard time time
seeing the difference between rising land and
ice.
Walking along the narrow cobblestone Rue Saint - Jean today, you will mostly
see small cafes, English - style pubs, restaurants and few dozen or so

There was a lot to
see that night: Rob Pruitt's psychedelic installation at the old Passerby space, with its promises of
ice cream and T - shirts, and Tobias Rehberger's bar at the Hôtel Americano and — Mr. Zwirner finally swung open the door to one gallery at a few minutes before 7, gamely holding it for the
masses as art handlers continued to work on the installation inside.
So — my speculation — maybe instead of pushing up a dome with a
mass of
ice lifted by the gas, we're
seeing a «Mentos» ebullition.
As you state his notion, he is assuming more carbon will be captured when the
ice melts and wondering why he doesn't
see that documented in the
mass media.
Also, I believe we are
seeing the beginning of a new glacial southern migration, the Arctic
ice cap has thinned and the surface
mass has been on the increase which to me is indicative of a glacial formation
We have joined forces with the Greenland expert Jason Box who has reconstructed the
mass balance of the Greenland
ice sheet since 1840 (Fig. 6 of our paper,
see also his blog).
The East Antarctic
Ice Sheet, long seen as the stable side of Antarctica's vast lode of ice, appears to have been losing mass, particularly in coastal regions, over the past three years, according to a new analysis using gravity measuremen

So we
see a long term trend of accelerating
ice mass loss since the 1970s.
What we do not
see in this image, but what clearly happened, was that an
ice mass hundreds of meters tall and covering an area of about 12.5 square kilometers was shattered into flinders as warming ocean waters invaded the Greenland Ice She

While Greenland was setting records linked to melting, another was being set around the chilly
mass of Antarctica, which
saw a new highest daily sea
ice extent.
When doing this with sea level data, as with OHC, as with tropospheric sensible heat, as with glacial
ice mass loss, we are
seeing a background, longer - term change that is non-linear, and for several decades now, accelerating.
It appears so many new Greenland
Ice papers are in the offing, and so much improvement in methodology, that we might
see a virtual doubling in both the quality of the data and the span of time accurate
mass change data is available.
You can
see the pictures / videos of land
ice mass change over here.
What Jimmy D also ignores is that
ice mass loss can also be due to: a) reduced precipitation b) reduced albedo due to reduced cloudiness (goes together with reduced precipitation) c) reduced albedo due to soot and / or volcanic ash, both of which have been
seen in the last five years d) other local phenomena
For the full set of SRES scenarios, a sea level rise of 0.09 to 0.88 m is projected for 1990 to 2100 (
see Figure 24), primarily from thermal expansion and loss of
mass from glaciers and
ice caps.
The most recent calculations of
ice mass balance in the antarctic also do indicate loss of
ice, though nothing close to the changes
seen in the arctic sea
ice and Greenland
ice sheet.
Thus the response to CO2 disturbances is slow enough to support the
mass balance argument and fast enough to support the stability as
seen in the
ice cores.
