ANTARCTIC Ice shelves stable over six years

ANTARCTIC ice shelves are showing no sign of climate change, six years of unique research have shown.

Scientists from Western Australia's Curtin University of Technology are using acoustic sensors developed to support the Comprehensive Nuclear Test Ban Treaty to listen for the sound of icebergs breaking away from the giant ice sheets of the south pole.

"More than six years of observation has not revealed any significant climatic trends," CUT associate professor Alexander Gavrilov said yesterday.

Professor Gavrilov and PhD student Binghui Li are investigating whether it is possible to detect and monitor significant changes in the disintegration rate of the Antarctic ice shelf by monitoring the noise of ice breaking.

The pair are using two acoustic stations, one 150km off Cape Leeuwin, the southwest tip of WA, and another off the gigantic US military base on Diego Garcia in the Chagos Archipelago, in the Indian Ocean.

"They are part of a network of underwater acoustic receivers, or hydrophones," Dr Gavrilov told The Australian yesterday.

The stations have been used to locate nuclear explosions detonated by India.

More than 100 signals from Antarctica are detected weekly by the Cape Leeuwin station. They are then transmitted to Geoscience Australia in Canberra.

Which is more proof of human created climate change.

If humans had not been around the poles would be much much larger.

80 million years ago the poles were at the equator.......apparently they shift around a lot without our help.......

There is a useful update of Arctic sea ice on pages 19-20 in the <a href=http://eospso.gsfc.nasa.gov/eos_observ/pdf/May_June_09_final.pdf>May-June 2009 issue of the NASA publication “The Earth Observer” </a> by Walt Meir and Stephanie Renfrow titled “Arctic Sea Ice News & Analysis: Arctic Sea Ice Younger, Thinner as Melt Season Begins”.

This informative article includes the text

“How vulnerable is the ice cover as we go into the summer melt season? To answer this question, scientists also need information about ice thickness. Indications of winter ice thickness, commonly derived from ice age estimates, reveal that the ice is thinner than average, suggesting that it is more susceptible to melting away during the coming summer.”

“While ice older than two years reached record lows, the fraction of second-year sea ice increased compared to last winter. Some of this second-year ice will survive the summer melt season to replenish the Arctic’s store of older ice; however, in recent years less young ice has made it through the summer. To restore the amount of older ice to pre-2000 levels, large amounts of this young ice would need to endure through summer for several years in a row.

But conditions may not always favor the survival of second-year and older ice. Each winter, winds and ocean currents move some sea ice out of the Arctic ocean. This winter, some second-year ice survived the 2008 melt season only to be pushed out of the Arctic by strong winter winds. Since the end of September 2008, 150,000 mi2 (390,000 km2) of second-year ice and 73,000 mi2 (190,000 km2) of older (more than two years old) ice moved out of the Arctic (Maslanik et al., 2007; Fowler et al., 2004).”

The entire article is worth reading.

Do these people really believe we are that gullible


Major sea level rise likely as Antarctic ice melts
By Richard Black
http://news.bbc.co.uk/2/hi/science/nature/8387137.stm

Sea levels are likely to rise by about 1.4m (4ft 6in) globally by 2100 as polar ice melts, according to a major review of climate change in Antarctica.

Conducted by the Scientific Committee on Antarctic Research (SCAR), it says that warming seas are accelerating melting in the west of the continent.

Ozone loss has cooled the region, it says, shielding it from global warming.

Rising temperatures in the Antarctic Peninsula are making life suitable for invasive species on land and sea.

The report - Antarctic Climate Change and the Environment - was written using contributions from 100 leading scientists in various disciplines, and reviewed by a further 200.

Rising seas: A tale of two cities

SCAR's executive director Dr Colin Summerhayes said it painted a picture of "the creeping global catastrophe that we face".

"The temperature of the air is increasing, the temperature of the ocean is increasing, sea levels are rising - and the Sun appears to have very little influence on what we see," he said.

SCAR's report comes 50 years to the day after the Antarctic Treaty, the international agreement regulating use of the territory, was opened for signing, and a week before the opening of the potentially seminal UN climate summit in Copenhagen.

High rise

Two years ago, the Intergovernmental Panel on Climate Change (IPCC) projected that the global average sea level would probably rise by 28-43 cm (11-16in) by the end of the century.

But it acknowledged this figure was almost certainly too low, because it was impossible to model "ice dynamics" - the acceleration in ice melting projected to occur as air and water temperatures rise.

Launching the SCAR report in London, lead editor John Turner from the British Antarctic Survey (BAS) suggested that observations on the ground had changed that picture, especially in parts of the West Antarctic ice sheet.

"Warmer water is getting under the edges of the West Antarctic ice sheet and accelerating the flow of ice into the ocean," he said.

Glaciers: If the world's mountain glaciers and icecaps melt, sea levels will rise by an estimated 0.5m
Thermal expansion: The expansion of warming oceans was the main factor contributing to sea level rise, in the 20th Century, and currently accounts for more than half of the observed rise in sea levels
Ice sheets: These vast reserves contain billions of tonnes of frozen water - if the largest of them (the East Antarctic ice sheet) melts, the global sea level will rise by an estimated 64m

By the end of the century, he said, the sheet will probably have lost enough ice alone to raise sea levels globally by "tens of centimetres".

The remainder of the projected rise would come from melting of the Greenland cap, melting of mountain glaciers in the Himalayas and Andes, and the expansion of seawater as it warms.

A number of research teams have come up with similar projections.

But this is the first time that an international body such as SCAR has endorsed the likelihood that sea levels will rise enough to threaten some of the world's biggest cities by the end of the century.

Cold store

The Antarctic Peninsula - the strip of land that points towards the southern tip of South America - has warmed by about 3C over the last 50 years, the fastest rise seen anywhere in the southern hemisphere, according to the report.

But the rest of the continent has remained largely immune from the global trend of rising temperatures.

Indeed, the continent's largest portion, East Antarctica, appears to have cooled, bringing a 10% increase in the sea ice extent since 1980.

This report backs the theory that it has bucked the global trend largely because of ozone depletion - the chemical havoc wrought over 30 years by chlorofluorocarbons (CFCs) and other agents in the stratosphere above the polar region.

"We used to have a big blanket of ozone, and when we took it away we saw a cooling," said Professor Turner.

"The Antarctic has been shielded from the impacts of global warming."

But, the report concludes, that will not last forever.

The ozone hole is expected to repair itself in about 50 years, now that the Montreal Protocol has curbed the use of ozone-destroying substances.

As it does so, the SCAR team predicts that greenhouse warming will come to dominate the temperature change across Antarctica, as in other parts of the planet.

Doubling of greenhouse gas concentrations in the atmosphere would warm the continent by 3-4C, it says.

The majority of Antarctica is so cold that a rise of this magnitude in air temperature would have little impact.

But more warming of the oceans would speed ice loss still further, the report concludes.

On the basis of declines seen around the Antarctic Peninsula, it would also be expected to bring significant reductions in the abundance of krill, a key foodstuff for baleen whales and other animals.

Among humankind, the frozen continent was once a preserve of explorers and scientists.

But now, about 30,000 tourists a year visit, some setting foot on outlying parts of the peninsula.

This increased human traffic, plus the warming on land and sea, are going to change the region's ecology, according to Julian Gutt, allowing organisms to enter and survive that were previously excluded through climate or simple geography.

"A good candidate is the stone crab (aka king crab) such as those found throughout Norwegian waters - they're more than a metre across from toe to toe.

"There are hints of it hopping across from South America - and that could completely change the ecosystem on the sea floor," said the Alfred Wegener Institute researcher.

About one third of one percent of Antarctica's land surface is ice-free; but already, non-native species are competing with native mosses for this meagre resource, Dr Gutt noted.

Pictures don`t lie.

If you don't believe Scientific studies,

I suggest you watch the ice melt live. A lot more interesting than watching grass grow!

Which of course proving it is melting. It is at its largest ice mass in 100 years or so. This of course proves that Co2 is causing warming and that industries must be shut down and taxes raised. It all makes such perfectly logical sense.

Put down your doubt and open your wallet then all will be well with the world.

The Poles used to be at the equator hundreds of millions of years ago,

I guess they migrated south in a pre-emptive attack against Co2 human induce globaloney warming.

Theory makes sense to me.

Ice mass loss values have been calculated from measurements taken by the GRACE (Gravity Recovery And Climate Experiment) satellites only since 2002. The GRACE satellites do not measure changes in ice loss directly, but rather, they measure changes in gravititational force. Changes in gravititational force can be caused by things other than ice mass loss, such as motion of the bedrock underlying the ice.

<a href="http://www.agu.org/pubs/crossref/2009/2009GC002642.shtml">http://www.agu.org/pubs/crossref/2009/2009GC002642.shtml</a>

“We present preliminary geodetic estimates for vertical bedrock velocity at twelve survey GPS stations in the West Antarctic GPS Network, an additional survey station in the northern Antarctic Peninsula, and eleven continuous GPS stations distributed across the continent. The spatial pattern of these velocities is not consistent with any postglacial rebound (PGR) model known to us. Four leading PGR models appear to be overpredicting uplift rates in the Transantarctic Mountains and West Antarctica and underpredicting them in the peninsula north of 65°. This discrepancy cannot be explained in terms of an elastic response to modern ice loss (except, perhaps, in part of the peninsula). Therefore, our initial geodetic results suggest that most GRACE ice mass rate estimates, which are critically dependent on a PGR correction, are systematically biased and are overpredicting ice loss for the continent as a whole”.

“Bevis, M., et al. (2009), Geodetic measurements of vertical crustal velocity in West Antarctica and the implications for ice mass balance, Geochem. Geophys. Geosyst., 10, Q10005, doi:10.1029/2009GC002642.”

Total Antarctic ice mass is about 26,800,000 gigatonnes. Claimed values for ice mass loss since 2002, compared to total Antarctic ice mass, are insignificant. They are lower than the rounding error, below the noise level, and beyond the capability of the GRACE satellites to accurately record.

The Antarctic ice area has <a href="http://noconsensus.files.wordpress.com/2009/10/antarctic-area.jpg">increased from 1979 to 2009</a>. The Antarctic ice volume is about 90% of the world’s ice volume, according to Table 6.1 in <a href="http://eospso.gsfc.nasa.gov/science_plan/Ch6.pdf">Chapter 6 of the Earth Observing System (EOS) Science Plan</a>.
