icecap, suggest an actual flow of CO2 going on, out of or into the soil in
which the trees are growing?»
There are also reports
which claim that the
icecap at the Antarctic and in Greenland are increasing.
In fact Iceland is one of the few areas at its latitude to have
icecaps,
which are largely absent at that latitude in Eurasia, and found futher north in Canada.
You might begin by wondering why you choose to get your information from websites like «
icecap»
which pontificate on the subject of drought when they don't even know the right sign for the PDSI.
I can not duplicate Mr. D'Aleo's graph of the PDO and AMO on Page 6 of the linked
ICECAP report,
which is your graph above with the title «PDO+AMO vs USHCN2 ″.
This suggests another thought provoking article you could write about the «melting
icecap reducing albedo

«Continuing to increase burning coal, oil and gas will soon drive atmospheric CO2 well over 400 ppm and ignite a devil's cauldron of melted
icecaps, bubbling permafrost, and combustible forests from
which there will be no turning back,» Hansen says.
During the Earth's ice ages the Pacific Ocean stored large amounts of carbon,
which for some reason it released again close to the last glacial period's end, warming the world and melting most of the
icecaps.
The carbon fee would be an insurance policy aimed at rapidly dropping the emissions blamed with increasing the average temperature of the world's land and atmosphere,
which are linked by scientists to increased melting of glaciers and
icecaps and rising sea levels that pose a direct threat to south Louisiana, he said.
This conclusion has subsequently been supported by an array of evidence that includes both additional large - scale surface temperature reconstructions and pronounced changes in a variety of local proxy indicators, such as melting on
icecaps and the retreat of glaciers around the world,
which in many cases appear to be unprecedented during at least the last 2000 years.
The Antarctic is a continent surrounded by ocean; the Arctic is a nearly landlocked sea surrounded by continents
which empty fresh water into it via north - flowing rivers; using the same word, «

* To avoid unacceptable risk of passing a point of no return beyond
which explosive feedbacks (
icecaps melting etc) are inevitable, we should aim to reduce CO2 concentrations to 350 ppm by 2100.
Here's a recent quote from an

Not just dwindling freshwater supplies,
which one speaker guessed would become a greater problem than the energy crisis, but also rising oceans as a result of melting
icecaps.
Something rather crucial that's been entirely missed by the «scientists» and the commenters here is the very large quantity of heat
which would be transferred to the Antarctic
icecap.
Since the
icecap is melting as the atmospheric levels of the greenhouse gas carbon dioxide rise, and global temperatures rise with them, as a consequence of the human combustion of fossil fuels, the rate at
which summer meltwater gets into the oceans becomes vital to climate calculations.
Dr Howat and his colleagues report in The Cryosphere that they measured a two kilometre - wide depression 70 metres deep in the
icecap of southwest Greenland,
which they then identified as «the first direct evidence for concentrated long - term storage and sudden release of meltwater at the bed».
