Tomorrow, the IPCC is scheduled to release its third and final report of 2007, covering strategies to reduce the greenhouse warming and prevent massive damage. The three reports of 2007 were one sign of renewed concern over global warming. Millions saw An Inconvenient Truth, history's first Oscar-worthy science lecture.

Earth's glaciers and ice caps move in response to gravity, and sea level rises when their ice enters the ocean. (In contrast, ice shelves and sea ice float, so the furious melting of Arctic ice will not directly affect sea level.) Not that the news from the North Pole is very comforting: On April 30, researchers reported that Arctic sea ice has been melting much faster than IPCC models forecast. "While the ice is disappearing faster than the computer models indicate, both observations and the models point in the same direction: the Arctic is losing ice at an increasingly rapid pace and the impact of greenhouse gases is growing," says Marika Holland, a scientist at the National Center for Atmospheric Research, a study co-author.

That’s why crystals at the nose are 1000 times bigger than at the source. Increasing outflow is a symptom of increased stress through increased pressure due to precipitation. Ground heat variation plays its part by varying moulin output. Reduction in sea ice is due to warmer water melting from below.
Until recently, melting glaciers got more attention than ice caps. But glaciers can only add a small amount to sea level rise, while the ice caps could add up to 70 meters.

The 2007 IPCC reports squarely blamed humans for global warming, yet were vague about sea level. Although the international panel projected a sea level rise of 0.18 to 0.59 meters by 2090 to 2099, compared to 1980 to 1999, it did not account for the new evidence on rapid glacier movement. According to Richard Alley, an ice expert and an author of IPCC's 2007 report, "We can provide neither a best estimate nor an upper limit on sea level rise, because of a lack of understanding of future changes in ice flow in response to future warming."

Learning from Larsen B

Although the B-breakup was dramatic, ice shelves do not affect sea level when they break up and melt, since they are already floating. Instead, the question regarding sea level was this: Would the adjacent ice sheet speed up after the release of pressure from the nearby ice shelf?

Breaking Up: Easy to do?
Rott said glaciers above the disintegrated ice shelf had accounted for "about 2 percent of total sea level rise" since 2002. This might not seem huge, but then again, this was just one glacier. The acceleration, Rott said, "demonstrates the vulnerability of ice shelves to climatic warming and the importance of ice shelves for the stability of glaciers up-stream."
Lucky the ice shelves reformed then.

The recent discovery of large lakes under the Antarctic ice cap has fueled this concern. Using a laser satellite that can measure height to within 1.5 centimeters, "We discovered pools of very large quantity, not a steady trickle," says first author Helen Fricker, a research geophysicist at Scripps Institution of Oceanography. The evidence suggested "rivers or channels connecting one lake to another."

So. The ice caps are moving faster but less predictably. What does this mean for sea level rise? Hard to say, and the IPCC, as mentioned, did not say. As Alley observes, the research is so new that prediction is not possible. (Fricker's lakes-in-Antarctica study, to take one example, was published after the IPCC deadline for considering research results.)

Strange she’s swallowed Hansen’s lubrication fantasy.Ice caps move faster - due to increased precipitation building layers of ice, increasing down force. Alley seems hooked on speed.
Still, the IPCC did try to give some framework for envisioning the effect of ice caps on sea level over the next century. For example, if ice flow speeds up in linear fashion with rising temperatures (meaning a straight-line graph can show changes in temperature and ice flow), it should be possible to anticipate sea level rise based on temperature forecasts. "Although there is no reason to expect the world to be linear, it's not a stupid thing to do," Alley says. This assumption yields a steady "but not immense," rise in sea level over the next century due to melting ice, he says.
>>>>It is stupid. It is an IPCC misrule that correlation equals causation. E.g. If heightened underground heat was to blame for seas warming and increased basal melt of glaciers, the IPCC AGW theory disintegrates and carbon credits become even more discreditable.

>>>> Warmer oceans cause increased precipitation. We should be worried about ground water reserve depletion.
Here's another take. Ice sheets have been fairly constant for the past 10,000 years or so, and snowfall on both ice sheets averages about 7 to 8 millimeters per year. "We can sort of figure that before humans started playing around with the system [by making gigatons of greenhouse gases], they were pretty close to balanced," Alley says. Thus ice sheets and glaciers released the same amount of water to the ocean around the edges that they accumulated up top, without changing sea level.
>>>> At times. Other times they caused falling ocean levels due to increased precipitation. A warmer ocean increases precipitation. Gigatons is a reference to the tiny percentage of airborne co2 we emit. 1-3 parts per million per year

Testing The Waters
"The peak level at Aberdeen was around 1950 at 7087 mm and the lowest point around 1889 at 6887 mm. The overall sea level rise since 1862 is around 70 mm (ie. less than 3 inches), or an averaged annual rate of around +0.5 mm/yr, half the rate recorded at Brest and less than one third the global rate claimed by the IPCC."
We need to know. What do we need to know?
Regarding fast-moving ice sheets, the 2007 IPCC reports on the inconvenient truth come at an inconvenient time: after the concerns arose, but before the scientific community figured out what to make of the recent observations.
>>>> We need to know the truth. The truth is, not enough is known to form anything but speculative opinion much less enough to justify draconian policies.
So what comes next? "It sounds self-serving, but we need a continuous set of measurements," says
>>>> It is self serving. How many billions this time? Global warming stopped, why is there need for haste? One measurement in midsummer and one in midwinter is enough.
Alley also stresses the need for better computer models. Many of the processes that affect ice sheets -- indeed the ice sheets themselves -- are absent from the computer models used to forecast the effects of global warming, he says. "If you worry about how much heat the ocean takes under an ice shelf, well, global computer models do not have an ice shelf. There are places where people do not know how deep the water is, so it's hard to write the equations."
>>>> An unprovoked admission of the inadequacy of present virtual reality programs and PCs. The actual quality is not a problem. It is improving certainly. What is a problem is the generated rhetoric based on false assumption leading to punitive and unfair extraction of money from the public purse by the climatic community.
An even more severe data void concerns the bottom of the ice sheet, certainly one of the more remote places on Earth. "Is the bottom smooth, bumpy, or muddy?" Alley asks. Bumpy bottoms would be less subject to the water lubrication issue we've noted, but "I dunno" is the only realistic answer to these questions.
>>>> Irrelevant nonsense. Except for the margins, both caps lie in depressions. To answer his question, sheet ice is believed to leave the surface topography depressed but otherwise unchanged. Earth heat causes higher basal temperatures. This can produce water that is forced by the weight on it into the ground and/or into the ice, and moulins. At depths of 10,000 feet, the weight of the ice is some 30 tons per square foot.

If ice sheets have such a major influence on sea level, and hence on coastal flooding, then computer modelers may need some help, Alley says. "If you look at the few ice-flow modelers, they are typing their fingers raw trying to get the code right. Putting a two-mile thick, one-continent wide ice sheet in a model is not an easy thing."
>>>> The ice cover, 1.5 miles thick on average (getting the numbers right would be a good start) is almost 3 miles thick in places.
In five years, Alley says, "We could start putting good limits on sea-level rise, but to say we have it nailed will take longer. I don't know how much longer."
>>>> 50% accurate occasionally. When you have so many models and projections, the occasional accidental match is inevitable. The attempts to predict future climate by weak guesswork and weaker assumption is not a good base for policy to be associated with.

Watch out Tuvalu, rising seas due to cooling water may be coming to get you. Nothing to do with human effects though so keep your fingers out of our wallets.
Do ice shelves in fact contribute to ocean warming? When they break up into icebergs, they carry their cooling influence away from the coast where the ice shelf reforms. So we end up with around double the original ice for a few years. Have the Larsons contributed to cooling the southern hemi? In fact the icebergs’ melting probably balances shelf growth. Earth is like that. Glaciation doesn’t appear to be biomass’ preferred condition.
Recent alarmism about quakes from glaciers is just fake alarm. Stick-slip quakes are a feature of the ice caps and there has been no noticeable increase in recent times.
Your article (Melting icecap triggering earthquakes, September 8) is misleading and alarmist. As a climatologist/seismologist working on glacial seismic activity in the Jakobshavn glacier basin - precisely the area your reporter mentions - I know that local earthquakes (or glacial quakes) are actually fairly common in the area and have been for a long time.
I also know that there is no evidence to suggest that these quakes "are happening far faster than ever anticipated" in the region, as Dr Corell of the global change programme at Washington's Heinz Centre is quoted as saying.
