It basically claims that the sensitivity is at the lowball of the current mainstream estimates, 2.4°C per doubling. It also points out that such sensitivity may result in as much change as has been seen from the last glacial maximum to the present day over the next couple hundred years.
That's pretty much in line with my take away on the other stuff I've read. That the climate change alarmists' suggestions for dealing with it are insane does not mean it is not going to be a seriously non-trivial problem. You are looking at sizeable dislocations of coastal communities, inundations of some island nations and, less certainly, aridification of large swaths of the tropics and sub-tropics.
How one concludes, "aw, hell, let's just keep on. It's all good" is a mystery to me.

Since you're directing your comment to me and you are posting a quote I have to assume you mean it to be mine. Or is this just an offhand way of putting words in my mouth?

Sorry about that. Since this is the "Climategate" thread, I meant it in the general direction of (a) anybody who is not already convinced that Rick Perry, Rush Limbaugh, et al, are either liars or morons and (b) everybody else still in the oh-well-it's-just-natural camp who is opposed to any action just because the leftists have been alarmists about proposed solutions.

Fine. Then the sane side that is supposedly made up of adults should acknowledge the problem and propose solutions that make sense. Not deny there is a problem and promote ignorant zealotry for fan points.

This may well be true, but, so far, attempts to deal with the science of climate change objectively have been largely forced to conceal such truths as may call into question global warming alarmism (even if only implicitly). The usual vehicle is peer review, and the changes imposed were often made in order to get a given paper published. Publication is, of course, essential for funding, promotion, etc. The following examples are but a few from cases that I am personally familiar with. These, almost certainly, barely scratch the surface. What is generally involved, is simply the inclusion of an irrelevant comment supporting global warming accepted wisdom. When the substance of the paper is described, it is generally claimed that the added comment represents the ‘true’ intent of the paper. In addition to the following examples, Appendix 2 offers excellent examples of ‘spin control.’...

A thorium cycle (which probably would have been the first choice way back when except for certain actors' desire for bomb grade material) avoids almost all the downside of the uranium cycle.
This needs to be explained, though it may be painful for those same parties to admit they really pushed the current incarnation of nuclear power mostly so they'd have a ready supply of Shit-To-Blow-Up-The-Planet-With.
Otherwise, concentrating on moving from coal and petroleum fired electric plants to natural gas plants, encouraging electric and hybrid cars using the (now much) cleaner electricity, eliminating incentives for coal use through the developed world, and getting the developing world (insofar as it is possible) moving toward natural gas, would be a good start.

I posted a thread here somewhere on an Indian plan to build a thorium reactor. Others here have noted in other threads that the US built an experimental thorium reactor in the fifties or sixties.
Natural gas is the near term answer and extracting more of same is critical to using it to replace coal but I can see a real possibility that the primary means of getting the NG, fracking, will be banned or severely restricted by the EPA.

It seems to be about twice as good on CO2, as well:

That's the best solution, I agree.

No the rate of sea level rise is falling. "Extreme weather Events"? Obviously you are talking about something other than the "Climate" as promulgated by IPCC and your claim is false anyway. And you are wrong about the Arctic Cap going more quickly than expected.
Could you possibly be anymore wrong?
What do you think about the latest sensitivity estimate of 2.4˚ That is less than a third of some of the original sensitivity estimates and much less than the current "consensus" of 3˚.
What are you alarmists going to do when the sensitivity drops so low that you don't have a cause? Directly supporting population controls?

Just as current temperature rises have been well within the predicted ranges. You don't seem to get the idea of prediction ranges. No one expects that the actual value will be equal to the point estimate..
What I was talking about with sea level rise was not an extension of current trends but likely changes in glacier behaviour in parts of the West Antarctic and Greenland Ice Caps. If all that happens is melting in place of these glaciers then sea level rise will be slow. The danger is that they might collapse instead. That is what happens at the end of glacials. Disappearance of pack ice can remove a brake on glaciers exiting to the sea leading to an acceleration of glacier flow. And parts of the ice sheets are grounded underwater. There is a danger that they might break up in place and float away. Some of them are already being eaten at from below. When would this happen? Not for a while but if it does we will have serious problems.

You seem to be missing the fact that that point has steadily declined from 10˚ down to the actual grey body value of .8˚ to 1.2˚ and the final result may even be negative.
