This video is of Michael Mann lecturing at Mount Holyoke College - a liberal arts college in Massachusetts - a few days ago. The quality of the video is poor but I think it's adequate. I'm posting it up now and will take a look myself later on tonight.
There is an introduction about the greenhouse effect which looks pretty dull. It starts to get interesting from about 20 mins or so.
The good bit though is at 34:30 or so, when Mann ascribes the divergence problem to "pollutants" and says that is was "scientifically appropriate" to delete the divergent data.
