Nord,
Your point about melting of Arctic sea-ice not changing ocean levels is correct, but in terms of general predictions about changes in sea level, you need to distinguish melting of sea-ice from melting of continental ice sheet. Melting of sea-ice doesn't change the volume of the ocean - since they are already in the ocean. When the ice cubes melt in your gin and tonic, they don't change the volume of the gin and tonic. Melting of continent based ice mass such as the greenland and West Antarctic Ice-Sheets could contribute to rising of sea-levels - though not as much as the thermal expansion of ocean water.
Antarctica is complicated since the West Antarctic region is warming as rapidly as the Arctic, while the interior of the continent and East Antarctica don't show any coherent trends - some places cooling as you say, other places warming depending on what period of time you look at.
Overall, its pretty apparent that the Arctic has warming and is changing faster than even the climate models predicted. Its all and well and good for us to argue about "global warming", but ask someone in Barrow what they think about climate change and I think you'll get a pretty unambiguous answer.

The scientists who espoused "global cooling" in the 70s were never more than a fringe group, much like the scientists of today who insist that global warming is not happening.
not according to the US senate committee of environment and public
works.
they released a report that states. the number of scientists that refute global warming are greater in number, than the scientists that support it.
Again $$$ plays a big part in them keeping their mouths shut. hundreds have been quoted as being afraid of the backlash and loss of funding that would follow them publishing their refuting statements.
It's all about money. the US can spend Billions and Billions to reduce pollutant's, all the while China is pumping 100 times more pollutants than we could ever pay to remove.
Gobal warming is just another reason to raise taxes, impose fines, spend billion is worthless R&D.
I will look for senate report. and post the link.. when i find it.

The list claims to have 400 signees (I didn't count, but it didn't look like 400 names to me). Thats not even close to the number of scientists that work on the IPCC.
In any event, most of the scientists quoted in the report weren't skeptical of Global Warming per se, some spoke out against Man-Made Global Warming, while others were only speaking out against the lunatic (think more alarmist than Al Gore) fringe that is making outragous predictions.0 -
rack , i live in southern tasmania...the hole in the ozone layer is right over tasmania as we speak!tasmania has the lowest rate of skin cancer in the country..and most of the cases here occur on the face/neck and the backs of the hand and the forearms. the hole in the ozone layer is not over northern australia!..please explain to me why skin cancers occur at a higher rate in northern australia than in tasmania? the hole in the ozone layer shrinks every winter and gets bigger every summer, why? 0 -

The link you post stinks of junk science. It has no citations to peer-reviewed publications, the organization was founded by and is run by the same guy who formulated the theory on which its message is based. This same guy appears to be the only staff member in the organization. And let's not forget:
quote: the Space and Science Research Center (SSRC) is the leading science and engineering research company internationally, that specializes in the analysis of and planning for climate changes based upon the "Relational Cycle Theory" which was formulated by the director/founder/apparent sole staffer. I suspect that the SSRC is not only the leading company, but also the ONLY company that specializes in analyses and planning based on the Relational Cycle Theory.0 -

I noticed that you failed to disagree about sea level or the effects of a northern polar melt, nor did you comment about the effects of increased evaporation and precipitation. Further, I believe that you may not realize that certain studies indicate our southern polar region seems to be in the process of cooling. Do you have data to the contrary?
I intentionally did not address those concerns because I prefer to only hit one point at a time.
I don't have the patience to wade through several points, line by line and post data to the contrary. This is especially true when responding to more than one poster.
I like to keep my posts as short as possible.0 -

Tasmania does have the lowest skin cancer rate in Australia (which has the highest rate in the world)
Tasmania's skin cancer rate is also the fastest growing in Australia0 -
rack, you are not going to convince me that i am wrong..and i am not going to convince you that you are wrong...lets just leave it at that...im goint to unsubscribe from the topic..its not worth the hassle of discussing it any more.after... i live here, and i dont get all my information from a government who is the same government who preaches that gun control lowers crime. 0 -
Huh? We're still arguing about the ozone layer?
LMAO!
That was announced (by British scientists) disputed (largely by US scientists) finally acknowledged by US scientists (once they figured out that their data management SOPs were flawed), and then acted upon by governments.
That was about 30 years ago. Reduction of CFC usage globally has had an impact. The ozone layer is recovering.
I can't believe we're still arguing about whether there is a hole in the ozone layer. It's a problem that already has been announced, debated, acted upon, and largely abated.0 -

Seems to me that you only use the government information that suits your own purposes. Just like shooting, its easier to see if you open both eyes.
In any event, if you don't wish to continue I won't press it.0 -

I see the antartica ice caps are melting. Wonder why if it is getting "colder"?????
Well, I guess I lied. I just can't let this one slide.
If you read "round one" you have already seen these. Now if you post the one where you saw the Antarctic Ice Cap is melting, we will have the balance.
Warming Is Blamed for Antarctics`s Weight Gain
Warming Is Blamed for Antarctica's Weight Gain
By KENNETH CHANG
Published: May 20, 2005
The eastern half of Antarctica is gaining weight, more than 45 billion tons a year, according to a new scientific study.
Data from satellites bouncing radar signals off the ground show that the surface of eastern Antarctica appears to be slowly growing higher, by about 1.8 centimeters a year, as snow and ice pile up.
The gain in eastern Antarctica snow partly offsets the rise in sea level caused by the melting of ice and snow in other parts of the world. The finding also matches expectations that the earth's warming temperatures would increase the amount of moisture in the air and lead to greater snowfall over Antarctica.
''It's been long predicted by climate models,'' said Dr. Curt H. Davis, a professor of electrical and computer engineering at the University of Missouri and the lead author of a paper that was published on the Web site of the journal Science yesterday. ''This is the first observational evidence.''
The accumulation occurring across 2.75 million square miles of eastern Antarctica corresponds to a gain of 45 billion tons of water a year or, equivalently, the removal of the top 0.12 millimeter of the world's oceans.
''This is the only large terrestrial ice body that is likely gaining mass rather than losing it,'' Dr. Davis said.
The data, from two European Space Agency satellites, cover 1992 to 2003, but because the satellites do not pass directly over the South Pole, they did not provide any information for a 1,150-mile-wide circular area around the pole. Assuming that snow was falling there at the same rate seen in the rest of Antarctica, the total gain in snowfall would correspond to a 0.18-millimeter-a-year drop in sea levels.
The data also deepen a mystery: Satellite measurements show that the level of the world's oceans has been rising about three millimeters a year in recent years, and scientists cannot figure out where all of the water is coming from.
Because water expands when it warms, the rise in global temperatures by itself causes sea levels to rise about one millimeter a year. The melting of glaciers in Greenland, Antarctica and elsewhere appears to account for another millimeter or so.
That leaves ''at least a missing millimeter a year to explain,'' said Dr. Robert Thomas, a glaciologist who works with NASA. ''This is perhaps another reason to suggest the information that Curt has presented doesn't include the entire picture.''
Dr. Thomas said that there could be as-yet-unseen melting of ice along the edges of Antarctica, where the satellites could not map the steeper coastal topography.
The new study is ''another piece of the puzzle that we're still putting together,'' said Dr. Waleed Abdalati, head of the cryospheric sciences branch at NASA's Goddard Space Flight Center in Greenbelt, Md., who was not involved in the research.
West Antarctic ice sheet is thickening
AS ARCTIC ICE MELTS, SOUTH POLE ICE GROWS
THE NEXT ICE AGE-NOW!
Glaciers are growing around the world, including the United States

A team of UK researchers claims to have new evidence that global warming is melting the ice in Antarctica faster than had previously been thought.
1. Scientists from the British Antarctic Survey (Bas) say the rise in sea levels around the world caused by the melting may have been under-estimated.
It is thought that over 13,000 sq km of sea ice in the Antarctic Peninsula has been lost over the last 50 years.
Wonder how 13,000 sq km melting off could make it heavier?0 -
Right or wrong sounds like another organization was formed to suck of the government teat. 0 -
if we all go to Al's house we will be safe.....he's got enough room & its guaranteed to be cool in the summer & warm in the winter & you'll get to meet hollywood experts in everything 0
