This is confirmed by gravity satellite measurements over the past 9 years which find that the rate of
ice mass loss has doubled over the last 9 years.
The blue line / crosses show monthly values
of ice mass.
Warming temperatures cause the ice sheets to thin and
lose ice mass around the edges.
I heard on the news yesterday that
sea ice mass in all the oceans is at a twenty - five year high, mainly because of the southern hemisphere.
By all means show the detail once we have people's attention but what needs to be understood is the
total ice mass loss.
How does research see the mechanism of the
global ice mass taking up its latent heat of fusion as giving us a false sense of security regarding global warming?
To reach further back in time and provide a long - term record that can inform global climate models, scientists are turning to other means of
measuring ice mass.
In the wake of an ice shelf collapse, however, the resulting glacier acceleration can raise sea level by introducing a new
ice mass into the ocean.
While this is unlikely for the foreseeable future, even a partial loss of these
huge ice masses could have a significant effect on coastal areas.
They investigated using different parameter values in the model and exploring the variation in the result and found a great deal of variation in
ice mass loss rates was possible.
Using gravity data to assess changes
in ice mass is not new.
When ice shelves already largely in the water break off from the
continental ice mass, this does not have much direct effect on sea level per se.
The most recent data from
ice mass balance buoys in Storfjroden, Svalbard and on iceberg - fast ice in Fram Strait show that the melt season has started.
The IceCon project [8] is investigating
Antarctic ice mass balance - the rate of loss of ice from the continent.
The East Antarctic ice sheet is the
largest ice mass on Earth, roughly the size of Australia.
Figure 1 shows gravity satellite measurements of
Greenland ice mass from April 2002 to February 2009 (Velicogna 2009).
Nicolas Bergeot from the Royal Observatory of Belgium talks about the interesting research
on ice mass balance and Earth's geomagnetic field he and his colleagues are carrying out at the Princess Elisabeth Antarctica research station.
The NASA study released 10/30/2015 concludes that Antarctica has been gaining
ice mass for over 10,000 years.
MEANWHILE, as the climate mafia bloviates inside their WEATHER = CLIMATE bubble, the other conveniently forgotten pole, Antarctica, continues its long 40 year + cooling trend,
gaining ice mass despite record and rising CO2 levels and claims of «The Hottest Years Evah ``...
Figure 2 shows gravity measurements of
land ice mass changes in Antarctica for the period April 2002 to February 2009 (Velicogna 2009).

Arctic ice mass balance buoys overview page.
Even NASA's gravity - sensing GRACE satellites, which have provided stunning
ice mass data since their launch in 2002, are nearing the end of their planned life.
It is virtually impossible to predict exactly
when ice masses of this size will calve.
The observed widespread warming of the atmosphere and ocean, together
with ice mass loss, support the conclusion that it is extremely unlikely that global climate change of the past 50 years can be explained without external forcing, and very likely that it is not due to known natural causes alone.
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.
Until that moment, the buoyancy of that section (i.e. whether or not it has enough
ice mass above sea level to remain grounded if exposed to the sea) has been irrelevant.
Greenland
surface ice mass balance has also reached a record high, defying the often heard claims that it's melting.
Change in land
ice mass since 2002 (Right: Greenland, Left: Antarctica).
Eight new GPS receivers have been installed on bedrock in the southern Antarctic Peninsula for improvements in glacial isostatic adjustment (GIA) model accuracy and GRACE -
based ice mass change estimates.
Indeed, satellite gravity data and radar altimetry reveal that the Totten Glacier of East Antarctica, which fronts a large
ice mass grounded below sea level, is now losing mass [90].
As I studied the evidence it became clear to me that the issue was real, and that as greenhouse gas levels increased we would
see ice mass disappearing and ocean heat content increasing before temperatures rose dramatically.
