Water vapour feedback continues to be the most consistently important feedback accounting for the large warming predicted by general circulation models in response to a doubling of CO2. Water vapour feedback acting alone approximately doubles the warming from what it would be for fixed water vapour (Cess et al., 1990; Hall and Manabe, 1999; Schneider et al., 1999; Held and Soden, 2000). Furthermore, water vapour feedback acts to amplify other feedbacks in models, such as cloud feedback and ice albedo feedback. If cloud feedback is strongly positive, the water vapour feedback can lead to 3.5 times as much warming as would be the case if water vapour concentration were held fixed (Hall and Manabe, 1999).

In 1997, the director, Martin Durkin, produced a very similar series for Channel 4 called “Against Nature”, which also maintained that global warming was a scam dreamt up by environmentalists. It was riddled with hilarious scientific howlers. More damagingly, the only way in which Durkin could sustain his thesis was to deceive the people he interviewed and to edit their answers to change their meaning. Following complaints by his interviewees, the Independent Television Commission found that “the views of the four complainants, as made clear to the interviewer, had been distorted by selective editing” and that they had been “misled as to the content and purpose of the programmes when they agreed to take part.”(14) Channel 4 was obliged to broadcast one of the most humiliating primetime apologies it has ever made

You seem to know what you're talking about and have dealt with several of the documentaries claims- however, they're not really the ones that I personally found troubling.
I wonder if you could address a couple of the ones that did seem, to me, to be troubling
1. the claim that, historically, global warming follows, pretty exactly, recorded sunspot activity.
Written by:
The terms “Little Ice Age” and “Medieval Warm Period” have been used to describe two past climate epochs in Europe and neighbouring regions during roughly the 17th to 19th and 11th to 14th centuries, respectively. The timing, however, of these cold and warm periods has recently been demonstrated to vary geographically over the globe in a considerable way (Bradley and Jones, 1993; Hughes and Diaz, 1994; Crowley and Lowery, 2000). Evidence from mountain glaciers does suggest increased glaciation in a number of widely spread regions outside Europe prior to the 20th century, including Alaska, New Zealand and Patagonia (Grove and Switsur, 1994). However, the timing of maximum glacial advances in these regions differs considerably, suggesting that they may represent largely independent regional climate changes, not a globally-synchronous increased glaciation (see Bradley, 1999). Thus current evidence does not support globally synchronous periods of anomalous cold or warmth over this timeframe, and the conventional terms of “Little Ice Age” and “Medieval Warm Period” appear to have limited utility in describing trends in hemispheric or global mean temperature changes in past centuries. With the more widespread proxy data and multi-proxy reconstructions of temperature change now available, the spatial and temporal character of these putative climate epochs can be reassessed.

The old London Bridge constricted flow through its multiple piers and restricted the tide with a weir. After the Bridge was replaced in the 1830s the tide came further upstream and freezes no longer occurred, despite a number of exceptionally cold winters. Winter 1962/3, for example, was the third coldest winter recorded in instrumental records extending back to 1659, yet the river only froze upstream of the present tidal limit.

2. that, historically, rises in co2 levels follow global temp increase, rather than precede it.
Which the documentary claimed cast doubt on current theories that co2 (from uman activivites)caused global warming.
Written by:
From model estimates, CO2 (along with other greenhouse gases CH4 and N2O) causes about half of the full glacial-to-interglacial warming.
So, in summary, the lag of CO2 behind temperature doesn't tell us much about global warming. [But it may give us a very interesting clue about why CO2 rises at the ends of ice ages. The 800-year lag is about the amount of time required to flush out the deep ocean through natural ocean currents. So CO2 might be stored in the deep ocean during ice ages, and then get released when the climate warms.]

The 2007 icpp report states that a significant human contribution to global warming is about 90% to 94% likely. At the risk of using evil reductionistic dualism logic (oh noes!), that means that the ipcc thinks there is at least a 6% chance of human effects not being significant.

Have you confused reductionism with subtraction??? What dualism??? Do you mean dualistic logic (binary logic or
Manichaean logic would also have made grammatical sense)??? I looked 'noes' up in the dictionary and it wasn't there... What exactly were you trying to say???

There's too many home fires burning and not enough trees
Written by: wikipedia
Trees sequester carbon through photosynthesis, converting carbon dioxide and water into oxygen and plant matter. Hence, forests that grow in area or density will reduce atmospheric CO2 levels. (Carbon is released if a tree or its lumber burns, but as long as the forest is able to grow back, the net result is carbon neutral.) In their 2001 assessment, the IPCC estimated the potential of biological mitigation options (mainly tree planting) is on the order of 100 Gigatonnes of Carbon (cumulative) by 2050, equivalent to about 10% to 20% of projected fossil fuel emissions during that period.[3].
However, the global cooling effect of forests from sequestration is not the only factor to be considered. For example, the planting of new forests may initially release some of the terrain's existing carbon stores into the atmosphere. Specifically, the conversion of peat bogs into oil palm plantations has allegedly made Indonesia the world's third largest producer of greenhouse gases.[4].

I would call 5% a insignificant chance at the best of times, but even if it were significant, that does not mean that any of the arguments have any more truth to them. What it does mean is that some other reason that has not already been cast aside (including solar heating) might be the MAIN cause.

Did it? I must have blinked. Please could you list the legitimate points that relate to the 5% chance that we are not the main cause of climate change?

I don't know about you guys, but I secretly want global warming to be identified as a natural phenomenon because I just don't see our society actually taking anything more than baby steps to curb our burning of fossil fuels. Myself included.

Sure they're truncated. The point of putting the two graphs together is to show the correlation, to do that you have to lay one on top of the other, and to do that you have to choose where to start the Y-axes to get them to fit on the same bit of 'paper' (okay, screen). It's not a distortion to line up the axes arbitrarily because they don't share a common zero point.

I never said that the axis' were distorted. They're truncated without reference to the truncation which automatically gets an F in graphing.
okay okay, so they don't have squiggly lines indicating a shifted axis. Big motherloving deal.

I can pick ANY line and easily line it up with that graph.
um, no you couldn't. Not, for example, a flat line, and definitely not any curve.

Like I said in reply to Rouge, correlation does not imply causation and sure, you can draw a graph to "show" that any two sets of statistics are correlated but to demonstrate a causal link you need a physical model to explain the causality.
But what you appear to be asserting is the notion "you can't ever show graphically that two things are correlated because a rearrangement of axes would show that they're not correlated."
In which case, oh no! for causation!

Personally, I really hope we ARE causing it - because then we have a very small chance of stopping it. If it was nature then we would be 100% committed to the disasters resulting from climate change. As it stands there is a tiny chance of us avoiding a lot of the problems - not enough of them to save large parts of the 3rd world, but that is a result of the inequality in this world.

I don't think we are so much causing it as kick starting an event that recurrs naturally, and as to stopping it, what could be the long term damage if the Earth doesn't have it's global warming phase? I'm sure the warming phase of the earth acts to increase sea levels and balance it'self out reduce land space and limit populations, has anyone thought of what could happen if we DO try and stop something the Earth wants to do? I find it the height of human conceit that we should even try, fair enough try and cut our input but stop it, that would be as wrong as starting it.
