I really don't remember stating that this will be the end-all-be-all of the debate. I simply stated that a rebuttal documentary was to be aired.
You appear to be the only one with a closed mind here. Are you worried, perhaps? A bit insecure?
TheRedneck
So you're watching a documentary which will question the claims of another documentary, lol.
There is no debate on the main issues. Just a lot of FUD from a group of shills and kooks.
Closedmind to what, RD? I've heard almost every argument you and other deniers have. They are generally tripe.

My arguments are based on the science and the science keeps coming.
Did the 'new' documentary focus on 'the' Hockey-stick?
RD: antartica's not melting
Me: It appears it is, look here's two studies*** one from 2006 and one brand new one from this month showing an acceleration in melting
RD: oh, it's just melting round the edges, overall there's no ice loss
Me: lol, but the actual data*** shows otherwise..
RD: *rinse, wash, repeat*

I like you too Mel. It's so much fun to watch you squirm your way through these debates while trying to act cool and collected.
I added that last line for completeness. Actually, I thought about adding the fact that I posted links to prove the Antarctic is not losing ice, but I didn't want to mess up such a fine and well-thought out quote.

According to Australian Antarctic Division glaciology program head Ian Allison, sea ice losses in west Antarctica over the past 30 years had been more than offset by increases in the Ross Sea region, just one sector of east Antarctica.
"Sea ice conditions have remained stable in Antarctica generally," Dr Allison said.
The melting of sea ice - fast ice and pack ice - does not cause sea levels to rise because the ice is in the water.
Dr Allison said there was not any evidence of significant change in the mass of ice shelves in east Antarctica nor any indication that its ice cap was melting.
"The only significant calvings in Antarctica have been in the west," he said.

It's the southern ozone hole whatdunit. That's why Antarctic sea ice is growing while at the other pole, Arctic ice is shrinking at record rates. It seems CFCs and other ozone-depleting chemicals have given the South Pole respite from global warming.
But only temporarily. According to John Turner of the British Antarctic Survey, the effect will last roughly another decade before Antarctic sea ice starts to decline as well.
Arctic sea ice is decreasing dramatically and reached a record low in 2007. But satellite images studied by Turner and his colleagues show that Antarctic sea ice is increasing in every month of the year expect January.

Using measurements of time-variable gravity from the Gravity Recovery and Climate Experiment (GRACE) satellites we determine mass variations of the Antarctic ice sheet during 2002-2005. We find that the ice sheet mass decreased significantly, at a rate of 152 ± 80 km3/year of ice, equivalent to 0.4 ± 0.2 mm/year of global sea level rise. Most of this mass loss came from the West Antarctic Ice Sheet.

Recent Antarctic ice mass loss from radar interferometry and regional climate modelling

Large uncertainties remain in the current and future contribution to sea level rise from Antarctica. Climate warming may increase snowfall in the continent's interior1, 2, 3, but enhance glacier discharge at the coast where warmer air and ocean temperatures erode the buttressing ice shelves4, 5, 6, 7, 8, 9, 10, 11. Here, we use satellite interferometric synthetic-aperture radar observations from 1992 to 2006 covering 85% of Antarctica's coastline to estimate the total mass flux into the ocean. We compare the mass fluxes from large drainage basin units with interior snow accumulation calculated from a regional atmospheric climate model for 1980 to 2004. In East Antarctica, small glacier losses in Wilkes Land and glacier gains at the mouths of the Filchner and Ross ice shelves combine to a near-zero loss of 4+/-61 Gt yr-1. In West Antarctica, widespread losses along the Bellingshausen and Amundsen seas increased the ice sheet loss by 59% in 10 years to reach 132+/-60 Gt yr-1 in 2006. In the Peninsula, losses increased by 140% to reach 60+/-46 Gt yr-1 in 2006. Losses are concentrated along narrow channels occupied by outlet glaciers and are caused by ongoing and past glacier acceleration. Changes in glacier flow therefore have a significant, if not dominant impact on ice sheet mass balance.
Increasing rates of ice mass loss from the Greenland and Antarctic ice sheets revealed by GRACE

Jet Propulsion Laboratory, California Institute of Technology, Pasadena, California, USA
We use monthly measurements of time-variable gravity from the GRACE (Gravity Recovery and Climate Experiment) satellite gravity mission to determine the ice mass-loss for the Greenland and Antarctic Ice Sheets during the period between April 2002 and February 2009. We find that during this time period the mass loss of the ice sheets is not a constant, but accelerating with time, i.e., that the GRACE observations are better represented by a quadratic trend than by a linear one, implying that the ice sheets contribution to sea level becomes larger with time. In Greenland, the mass loss increased from 137 Gt/yr in 2002–2003 to 286 Gt/yr in 2007–2009, i.e., an acceleration of −30 ± 11 Gt/yr2 in 2002–2009. In Antarctica the mass loss increased from 104 Gt/yr in 2002–2006 to 246 Gt/yr in 2006–2009, i.e., an acceleration of −26 ± 14 Gt/yr2 in 2002–2009. The observed acceleration in ice sheet mass loss helps reconcile GRACE ice mass estimates obtained for different time periods.

People might like to think I represent some form of closed-minded agenda, but I'm more interested in veracity of information and presenting the current science.
'Dr' Vincent Gray is no doctor. He has no PhD. He has no training in climate science. He's just a random person who signed up to review the IPCC reports and represents a group ofbackwardsdownunder deniers.
[D]rafts are circulated to specialists with significant expertise and publications in the field. A wide circulation process ensures contributions from independent experts in all regions of the world and all relevant disciplines. Revised drafts are distributed for the second review to governments and to all authors and expert reviewers.
Who cares what he thinks?
I know its disappointing that all you can do is lie and misrepresent to bolster your ideological viewpoints, but that's life.
It first needs to be emphasized that natural variability and radiatively forced warming are not competing in some no-holds barred scientific smack down as explanations for the behavior of the global mean temperature over the past century. Both certainly played a role in the evolution of the temperature trajectory over the 20th century, and significant issues remain to be resolved about their relative importance. However, the salient point, one that is oftentimes not clear in arguments about variability in the climate system, is that all else being equal, climate variability and climate sensitivity are flip sides of the same coin.
[W]hen the major modes of Northern Hemisphere climate variability are synchronized, or resonate, and the coupling between those modes simultaneously increases, the climate system appears to be thrown into a new state, marked by a break in the global mean temperature trend and in the character of El Nino/Southern Oscillation variability.
Here, a new and improved means to quantify the coupling between climate modes confirms that another synchronization of these modes, followed by an increase in coupling occurred in 2001/02. This suggests that a break in the global mean temperature trend from the consistent warming over the 1976/77–2001/02 period may have occurred.
"Decadal predictions"
(Gavin A. Schmidt)
There has been a lot of discussion about decadal climate predictions in recent months. It came up as part of the ‘climate services’ discussion and was alluded to in the rather confused New Scientist piece a couple of weeks ago.
…
One thing that is of concern are statements that appear to assume that this is already a done deal – that good quality decadal forecasts are somehow guaranteed (if only a new center can be built, or if a faster computer was used).
If you didn't spout such obvious tripe which can be shown to be erroneous so easily, then all would be well. Closed-mindedness is effectively closing your mind to evidence, I've seen almost every denier argument, and all are BS.
Chris Landsea is a butthurt scientist who was a little peeved that his pet scientific position was not accepted by a lead IPCC scientist (Trenberth) who signified a different position from hisself when giving a talk.
the projections are based on model results that provide differences of the future climate relative to that today. None of the models used by IPCC are initialized to the observed state and none of the climate states in the models correspond even remotely to the current observed climate.
I have often seen references to predictions of future climate by the Intergovernmental Panel on Climate Change (IPCC), presumably through the IPCC assessments ... . In fact, since the last report it is also often stated that the science is settled or done and now is the time for action.
"Correlation does not equal causation."
Landsea says no effect on hurricanes, others like Kerry Emanuel say there might well be (which Trenberth agrees with).

Let's say for the sake of discussion that you are absolutely correct: the total amount of ice is fairly constant, but sea ice in the east is increasing while continental ice in the west is decreasing (I am not going into the semantics of how one determines east and west at one of the poles; it suffices to define west as opposite to east).
So if one side is increasing while the other side is decreasing, that would mean that the overall ice coverage is moving.

"You have to face it. No model has ever successfully forecast any future climate in quantitative terms. It is surely because they incorporate only one of the many influences on the climate, increases in greenhouse gases. Why should any of us believe them?"
and:
"Insert before "Confidence" "Despite the total absence of any succedssful future climate prediction"
and again:
"Insert after "above" "but no evidence of any actual succesful prediction"
and yet again:
"Insert after ."(see Chapter 8)" "but not from a single successful forecast"
all by Vincent Gray. I found 7 of these all up. Methinks someone is trying to make a point.
The chief defect of this chapter is the total absence on the main greenhouse gas, water vapour. By comparison, the others are insignificant. The usual excuse for this blatant ommision is that the computer models are so defective that the only way they can deal with the undoubted importance of water vapour is to relegate it to the status of a "feedback", and remove its importance from public scurtiny
VINCENT GRAY
The global warming scam is the result of the widespread belief in a new religion, based on the deification of a nebulous entity, ‘The Environment’. ‘The Environment’ is an extension of the concept of ‘Nature’ which was held sacred by the Romantics, but it is a much more demanding deity, requiring constant and increasing sacrifices from humans. Environmentalism is just the latest attempt to find a substitute for the theory of evolution and it is paradoxical that it can be so widespread when next year (2009) is the 200th birthday of Charles Darwin and the 150th anniversary of the publication of his major work “The Origin of Species as the Result of Natural Selection”. All of the basic beliefs of Environmentalism are in direct conflict with contemporary understanding of the principles of Darwinism. Despite this fact, many scientists are supporters of Environmentalist dogmas and some are prepared to claim that they are compatible with Darwinism.
Vincent Gray 'The global warming scam'
The most dishonest statement in the 4th Science Report of the IPCC (Solomon et al. 2007), is to be found in the Frequently Asked Questions section on page 104:
"A common confusion between weather and climate arises when scientists are asked how they can predict climate 50 years from now when they cannot predict the weather a few weeks from now. The chaotic nature of weather makes it unpredictable beyond a few days. Projecting changes in climate (i.e., long-term average weather) due to changes in atmospheric composition or other factors is a very different and much more manageable issue. As an analogy, while it is impossible to predict the age at which any particular man will die, we can say with high confidence that the average age of death for men in industrialised countries is about 75."
This statement makes no logical sense. If “the chaotic nature” of “weather” makes it “unpredictable” then how can changing its name to “climate” suddenly make it “a more manageable issue”? The question is supposed to be about forecasting, yet we are given an example suggesting that an “average” has “high confidence” when an individual figure has not — a completely irrelevant proposition. There is no guide on how future “averages” or individual figures for the age of death might be forecast. If the suggestion that future “climate” can be forecast when future “weather” cannot were true, one might ask why weather forecasters seem to be unable to find a way of suddenly removing all the “chaos”. The “analogy” is ridiculous. There is no suggestion that we can predict either the average age of death or that of an individual by any known method. There is no evidence whatsoever that the “chaos” associated with the weather has been eliminated or made “more manageable” merely because they changed the name to “climate”.

We thank Vincent for his diligence in wriritng so many comments. However, the comments would be much more useful if they were backed up by other than opinion.

Climate Scientist Chris Landsea Quits IPCC.
--------------------------------------------------------------------------------
In his letter of resignation (see below) Landsea Blasts Politicized 'Preconceived Agendas' of IPCC.
[Landsea is one of the world's leading hurricane researchers, specializing in seasonal and climatic relationships of Atlantic tropical cyclones. He served as chair of the American Meteorological Society's (AMS) Committee on Tropical Meteorology and Tropical Cyclones for the years 2000-2002. He was recipient of a National Oceanic and Atmospheric Administration (NOAA) Post-Doctoral Fellowship in Climate and Global Change for the period 1995-1996.]
An Open Letter to the Community from Chris Landsea.
Dear Colleagues,
After some prolonged deliberation, I have decided to withdraw from participating in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). I am withdrawing because I have come to view the part of the IPCC to which my expertise is relevant as having become politicized. In addition, when I have raised my concerns to the IPCC leadership, their response was simply to dismiss my concerns.
With this open letter to the community, I wish to explain the basis for my decision and bring awareness to what I view as a problem in the IPCC process. The IPCC is a group of climate researchers from around the world that every few years summarize how climate is changing and how it may be altered in the future due to manmade global warming. I had served both as an author for the Observations chapter and a Reviewer for the 2nd Assessment Report in 1995 and the 3rd Assessment Report in 2001, primarily on the topic of tropical cyclones (hurricanes and typhoons). My work on hurricanes, and tropical cyclones more generally, has been widely cited by the IPCC. For the upcoming AR4, I was asked several weeks ago by the Observations chapter Lead Author Dr. Kevin Trenberth to provide the writeup for Atlantic hurricanes. As I had in the past, I agreed to assist the IPCC in what I thought was to be an important and politically neutral determination of what is happening with our climate.

How Scientists are Fired and Intimidated
The ice-core man
Lawrence Solomon, Financial Post
Published: Friday, May 04, 2007
"...Because of the high importance of this realization, in 1994 Dr. Jaworowski, together with a team from the Norwegian Institute for Energy Technics, proposed a research project on the reliability of trace-gas determinations in the polar ice. The prospective sponsors of the research refused to fund it, claiming the research would be "immoral" if it served to undermine the foundations of climate research.
The refusal did not come as a surprise. Several years earlier, in a peer-reviewed article published by the Norwegian Polar Institute, Dr. Jaworowski criticized the methods by which CO2 levels were ascertained from ice cores, and cast doubt on the global-warming hypothesis. The institutes director, while agreeing to publish his article, also warned Dr. Jaworowski that "this is not the way one gets research projects." Once published, the institute came under fire, especially since the report soon sold out and was reprinted. Said one prominent critic, "this paper puts the Norsk Polarinstitutt in disrepute." Although none of the critics faulted Dr. Jaworowskis science, the institute nevertheless fired him to maintain its access to funding."
An original paper for the Science and Public Policy Institute (SPPI)
The price for speaking out against global warming is exile from your peers, even if you are at the top of your field.
What follows is an example of a scientific group that not only stopped a leading researcher from attending a meeting, but then—without discussing the evidence—applauds the IPCC and recommends urgent policies to reduce greenhouse gases. What has science been reduced to if bear biologists feel they can effectively issue ad hoc recommendations on worldwide energy use? How low have standards sunk if informed opinion is censored, while uninformed opinion is elevated to official policy? If a leading researcher can’t speak his mind without punishment by exile, what chance would any up-and-coming researcher have? As Mitchell Taylor points out “It’s a good way to maintain consensus”.
And so it is. But it’s not science.
Mitchell Taylor is a Polar Bear researcher who has caught more polar bears and worked on more polar bear groups than any other, but he was effectively ostracized from the Polar Bear Specialist Group (PBSG) specifically because he has publicly expressed doubts that there is a crisis due to carbon dioxide emissions.
Current warmth seems to be occurring nearly everywhere at the same time and is largest at high latitudes in the Northern Hemisphere. Over the last 50 years, the largest annual and seasonal warmings have occurred in Alaska, Siberia and the Antarctic Peninsula. Most ocean areas have warmed. Because these areas are remote and far away from major cities, it is clear to climatologists that the warming is not due to the influence of pollution from urban areas.
