Here is the second part of the BBC's show featuring Naomi Oreskes and Dr Karl. This is extremely disreputable stuff - you will hear Naomi Oreskes say that the Medieval Warm Period was restricted to Europe (don't think so) and the current warming is greater in magnitude. You will also hear Oreskes engage in a particularly grubby smear of Henrik Svensmark and then, to add insult to injury, you will hear Dr Karl say that Svensmark's work was debunked a decade ago (in the week that it was experimentally confirmed!).
Even more remarkably, Dr Karl claims that the worst finding the CRU inquiries made was that scientists were not nice to each other - really!! Maybe he thinks a finding that "hide the decline" was "misleading" is just not serious at all. Amazing stuff. Do people in Australia find Dr Karl a credible source of information?
