In September 2006 I noticed massive outpourings of water from underneath the ross ice sheet, all efforts to bring this to the attention of those that study these things seemed to no avail, now, nearly a year later, it appears there is acknowlegement that what I saw in the images shown below, was in fact, something of great importance.
"The six experts described the Earth as being in "imminent peril" and warned that a UN panel on climate change grossly underestimated the scale of sea-level increases this century. In an article published in the journal the "Philosophical Transactions of the Royal Society A.", the group led by James Hansen, the director of NASA's Goddard Institute for Space Studies wrote: "Recent greenhouse gas emissions place the Earth perilously close to dramatic climate change that could run out of control, with great dangers for humans and other creatures." The paper predicts that sea levels may rise by several metres by 2100, compared with a forecast from the UN Intergovernmental Panel on Climate Change published in February that predicts sea levels increasing between 18 and 59 centimetres.

I received a very pleasant email in september 2006, from SSEC/UW but I don't believe a word of it
Hello Arnaldo,
Thanks for your e-mail. Actually, what is occurring around Ross Island maybe more to natural sea ice formation and movement out of the region out into the greater Ross Sea, rather than a "melt" per se. For the past several years tabular iceberg have blocked much of the sea ice from having an easy access to moving away from the region. Now, only one tabular iceberg, B-15J, remains. Hence, sea ice, under influence of wind and wind stress, as well as other forces, moves the sea ice around much more dynamically without those tabular icebergs around.
Over the last 72 hours, the Ross Island region is being affected by a significant late winter storm, which will affect the sea ice around the area (due to high winds, etc.). It may also be a catalyst for opening up small polnya, or patches of unfrozen ocean, near by. Hence, it looks like the region has sea ice "melting" when it really is not. The sea ice is simply pushed away from the region.
I hope this helps!
Best Regards,

For many years, each morning I have been watching the satellite imagery of the Ross ice sheet, this morning I noted what appears to be a large undersea volcano, melting the ice of the Antarctic ice sheet. Note the flows on either side of Ross island have in one day, washed away the pack ice!
A web search this morning indicates no mention of this anomaly in the news. Temperatures are indicated by the black numbers in degrees Farenheit Click image above for full image with annotations by Arnie Lerma and image enhancement of flow
Original images are linked form THIS page Tell me what you think Seems the same area is NOT available in the September 19th images
However... look at what is, the annotations are mine... click on that image to goto the original from THIS PAGE
For an undetermined length of time following this event Telemetry from McMurdo was "unavailable" An over view map show what is where is HERE NARRATOR: But where is the water coming from? Why is the base of the ice melting? While flying over the ice sheet, Don Blankenship's sensors picked up evidence of magnetic rock, and a cone-shaped mountain beneath the ice. At the surface, there was a round depression—four miles wide.
NARRATOR: It was an active volcano, melting the bottom of the ice. Even a volcano isn't enough to destroy an entire ice sheet, but it is evidence of some major geological activity. Don made his discovery just west of the Transantarctic Mountains. Here, two continental plates have moved apart. In the middle, the earth's crust is very thin, allowing heat to flow up from below. This could be contributing water to the base of the ice streams. But scientists worry there could be an additional source of heat. Compare above to 22 November 2006 images clearing showing renewed icemelt

Massive ice shelf 'may collapse without warning'
1.00pm Wednesday November 29, 2006
The Ross Ice Shelf, a massive piece of ice the size of France, could break off without warning causing a dramatic rise in sea levels, warn New Zealand scientists working in Antarctica.
A New Zealand-led ice drilling team has recovered three million years of climate history from samples which gives clues as to what may happen in the future.- LINK to originala rticle at the New Zealand Herald

Cracks 100's of miles long appearing in antarctic ross ice shelf
This image from Dec 28th 2006 clearly shows 3 enormous cracks in the Ross ice shelf, complete collapse of the Ross shelf would raise sea levels, flooding parts of manhattan island.
This image from Jan 3rd 2007, shows a new melt water fissure, and the breakup of the "fast ice" that was previously north of ross iceland.
