   I find the video (I did not check the booklet) quite informative and useful as an entry level teaching tool. The only inaccurate (to my liking) detail is: - the suggestion that the current total energy imbalance due to all forcings is 1.6Wm-2. That's is incorrect, because the temps has risen by .6C, therefore increasing the heat loss due to IR by ~1Wm-2 since preindustrial, therefore the current imbalance is 0.6Wm-2 and that (rather than 1.6Wm-2) is the equivalent of 2HBsec-1 they are talking about thereafter.

   In addition to the video series mentioned above, it may be interesting for those who like videos (I really hate! internet videos) that the "German Advisory Council on Global Change" (WBGU) has published another video series recently. It's a kind of "Video Seminar" that adds to a report named "World in Transition – A Social contract for Sustainability" and covers a broad range of topics. For further information you may have a look at: E-Seminar "Transformation" [WBGU, english]

   Pretty nice video with well-produced graphics. I did notice, however, at about 11.5 minutes in, there was a small discussion about atmospheric methane that includes the assertion that its concentration has "leveled-off." The chart shown terminates at 2006. It should be noted that since 2006, atmospheric methane concentrations have increased steadily. More data here: http://www.esrl.noaa.gov/gmd/aggi/

   The video is excellent. These are exactly what is needed to help educate the ignorant. I think non-emotional professionally done videos like this have more potential to turn a contrarian-bias mind. 2/3 of these people are nearly a lost hope anyway, and a passionate, overbearing or spiteful message will only further entrench them. For the other 1/3 (who still have a thread of true skepticism), they will only be receptive to these sorts of very educational and fair-balanced, non-polarizing messages. This is the way to go! Unfortunately, there are too FEW of these available. Why is that? In my opinion, the climate change collegiate are, sadly, a dis-organized crew (understandably because their agenda isn't based on contrived cooked information). But, a little more organization would still help a lot. That's what makes this SkS site so good (a clear organized light in the abundant sea of conflicting messages). One obvious omission is a conservative (low-end) projection to 2100 based on BAU, or better yet, a moderate reduction in GH emissions (starting in say 2025). Even a conservative projection like this would be a big eye-opener for many. ... I will be sharing the youtube site. ... Thanks for sharing here!

   The radiative forcing is indeed greater than the observed temperature rise. This doesn't necessarily mean that the radiative forcing is in error. It could easily be that Giai's feed back mechanisms are "fighting" against the radiative forcing. The possibility is that this is a 'light switch' phenomenon and that when forced far enough, we will see a step change to a warmer world in keeping with the level of radiative forcing. An ice free Arctic ocean in, say, July might be when we will see such a lurch upward.

   These videos are very good for genuine skeptics who are prepared to be open minded - and I'd include thousands of people who have been fed misinformation in that description. It is very U.S. centred - but that is probably a good thing. I'd like to see something similar come from the Royal Society.
