    That's a start -- that's the initially (several years ago) recommended carbon tax. It's enough to change behavior and create markets for products that support further future change. If we tried to go from our current habits to zero (or rather, low) carbon in one year, that would probably be unpleasant, and would in fact be bad for the economy. Start small, change gradually, not so bad.

    The longer we put this off, the faster we'll need to change to get the same (lack of) effect on the climate, and the larger the actual societal implications. From my POV, someone who advocates delay in order to avoid drastic and unpleasant economic change is setting us up for exactly that just a few years (decades?) down the road when AGW has progressed to a more-obvious state.

    The IPCC report is unspeculative, as much as one can be when talking about future outcomes. I think we are in violent agreement on what constitutes conservative science, we merely disagree whether the IPCC is an example of that. The basic science behind global warming is old, simple, and well-understood. The devil is in the details -- the feedback loops, the delays, and the buffers.

    "huge societal implications should be reported"

    I assume that you're talking about recommended changes in how we produce energy as having huge societal implications. It might not hurt to have models and evidence to justify that. Big industry in this country has a long track record of crying "wolf" about the economy-destroying implications of various regulations (and conservative have a pretty good track record of mispredicting economic outcomes). We could, for example, add a carbon tax, but reduce some other tax (e.g., social security) in a revenue-neutral way. Small taxes (I've heard $40/CO2-ton initially, roughly $.40/gallon for gasoline) would get people's attention, yet not destroy the economy -- anyone who really wanted to drive somewhere, would have extra money in their pocket to spend on gasoline. We also have quite a few existence proofs for countries full of happy healthy people who pay far more for gasoline than we do. So when you say "huge societal implications", suddenly *I'm* going to be a tad skeptical :-). I just don't buy it -- we've actually had other countries run the experiment, and it seems to work okay for them. Why are we so different?

    Current political "conservatives" are mislabeled in my opinion. In the scientific sense, "conservative" predictions are those that are supported by as much proof/data/modeling as possible.

    In the case of the IPCC, to me, their conservativism says that we should (all) expect AT LEAST the change that they are predicting, and that is precisely what political conservatives are NOT doing. The closest they get to recognizing the work of the IPCC is when they cite it as either (a) an upper limit on what could happen ("and that's not so bad, is it?") or (b) misinterpret it in bogus games of "gotcha" (Monckton apparently did this, conflating equilibrium temperature projections at particular CO2 levels, with the temperature observed when the CO2 level first reached those levels -- it takes decades-to-centuries to hit equilibrium.)

    There's a third sense of conservatism, which suggests that we should not only avoid high risks, but that we should also keep an eye out for low-likelihood high-cost events. A bird flu epidemic; that would be bad. An asteroid strike, that would be bad. Some of the we-haven't-ruled-this-out-completely climate projections would also be bad -- on the emissions path we're on, how sure are we that the anoxic oceans won't happen? There have been well-researched possible-predictions of a sudden onset of rapid sea-level rise (5cm/year, for a century or two). At the higher limits of projected temperature rise, some parts of the world are supposed to become uninhabitable -- sometimes so hot and humid that a person could not avoid fatally overheating in the course of a few hours. And all these things, when they appear in the press, are OMG-we're-all-gonna-die!, which is ridiculous, but that doesn't mean that the risk is anywhere near zero, and the cost-weighted risk is pretty high because the outcome is potentially very costly. The fear-mongers are not exactly helpful to anyone.

    This is my main problem with current political "conservatives", because in these two traditional senses of the word, they're not. They don't respect sober, conservative science, and they don't take a conservative approach to low-probability-high-cost risks -- excepting terrorism, in which case, the one percent doctrine applies.

    And it's that ice cap melting that I think is the subject of a lot of current head and chin-scratching -- is it changing the weather, and if so, how? Apparently some models say yes, some say no, hard to tell. But it would be surprising if it did nothing. Medium-term, a whole lot depends on that ice cap -- the more open water, the lower the albedo, the more heat accumulates in the summer, the more chance of releasing methane when the water warms.

    The 2007 report also explicitly ignores sea level chance from Greenland/Antarctic ice sheet melting, largely because they did not feel that they had good models for this yet (I think they say this), and the geological record shows it occurring slowly (they say or imply this), and the actual energy required to melt the ice sheets in place is quite enormous (as opposed to sliding them off into the ocean and melting them there, where ample heat is available -- math here: http://dr2chase.wordpress.com/2012/02/04/numbers-that-were-larger-than-i-had-imagined/ )

    To restate -- it does take money to form an insurance company, so if there is not money out there looking for investment, it's not too likely someone would invest in the insurance business. The existence of a healthy (urk) market for CDOs and similar investment gadgets, pre-bust, indicated that there was money out there looking for profitable investments. If an insurance market is overpriced (and my parents certainly believed that it was, relative to buying storm shutters), then an investment in entering that market and charging lower-but-still-risk-profitable rates should be profitable.

    And if the invisible hand (of the market) works, those profitable investments will occur, especially since no innovation is required, just fair and accurate pricing. People are always looking for a way to make a buck.

    So maybe the invisible hand doesn't work, or maybe insurance is priced close enough to actual risk that the investment in forming a new insurance company would not be profitable. But insurance rates have definitely gone up in recent years. Hurricane-statistically, the year Katrina occurred was damn creepy; I believe that year half of the top-6-most-intense storms for the Atlantic were replaced (Katrina, Rita, Wilma).

    Do I think this will certainly happen? No, not today, but I'd like to be a good deal more certain that it won't. In my opinion you overstate the certainty that it won't happen. The risk is affected both by the range of warming and the rate of warming -- slow warming releases frozen methane slowly (it has a relatively short residence time in the atmosphere compared to CO2), rapid warming might deliver it all in one geologically quick burp.

    The state of the art has been pretty good at predicting rates and ranges of maximum and minimum temperatures. We don't know for sure what the temperature will be, but we can state with pretty good confidence that it will be between a lower and upper limit. For example, it is a good bet that on any given day, the temperature that day will stay between the maximum and minimum temperatures observed that day in the last 100 years. And it should be a safe bet (in general) that it's equally likely that we would exceed the minimum or the maximum temperature.

    However, recent trends have made these two bets not so safe; it is more than normally likely that we will set a record, and the distribution is skewed warm -- we tend to break high records, not low records.
