WUWT readers may recall this story from November 3rd NOAA deletes an “inconvenient” kids science web page where NOAA took down a web page called “It’s a gas, man” that talked about a tabletop science demonstration that kids could do themselves to “prove” that CO2 retains more heat. Problem was, the experiment as presented then was flawed, and when it received some attention from skeptical websites, NOAA recognized the flaw and took it down, replacing it later with an updated page.
Fast forward past Climategate to this past Thursday Dec 17th, and we find that the BBC decides to try essentially the same experiment on live TV for an impressed and non questioning audience.
Click to play the video at the BBC website Only one problem, the BBC presenters botched the experiment. Fortunately we can show why, because WUWT reader Professor Kevin Kilty of the University of Wyoming, who took an interest in recreating this experiment with students in his physics class well before the BBC did their experiment, has conclusively demonstrated its scientific shortcomings in an experiment log he sent me on December 20th showing results of a November 23rd experiment run.
What got me connecting what Professor Kilty had done to the BBC live TV experiment was a comment from WUWT reader Bryan C of the UK. Here’s an excerpt:
Dear Anthony
Here’s something I found shocking and that you don’t see every day: the British government’s former chief scientific adviser Professor Sir David King flagrantly lying on national television to boost the dubious idea that some foreign agency (the Russian secret service?) was behind Climategate.
http://news.bbc.co.uk/2/hi/programmes/newsnight/8418356.stm
This was in the context of BBC 2’s Newsnight staging a peculiar experiment, with a politically-correct black female “space scientist” heating two bottles – one containing “air” (last time I looked, that included carbon dioxide anyway) and one containing “atmospheric air with a greater concentration of carbon dioxide” (they didn’t say how much they were adding, of course, but I’d bet it was substantially more than 0.000388%!). Surprise, surprise — the latter bottle grew hotter… Of course it did. A greater amount of carbon dioxide will be warmer when heat is applied. This is not a surprise! The proportions are key, of course, as you know.
Newsnight itself characterised the effort right at the start as a “very unscientific experiment” — so why do it at all?! In fact the “science” as presented was misleading and selective to the point of deception.
Indeed when you watch the BBC video, it is clear that there’s no sort of control of any kind, the thermocouples were placed haphazardly at different angles into the bottles, and there’s likely alignment differences between the lights illuminating the bottles. It seems so from my viewing of the video.
Professor Kilty also viewed the BBC video and writes:
You can see that the two bottles start at temperatures of 32+ C. Perhaps the house is this warm, we don’t keep ours this warm, but more likely they have run the experiment and know pretty well in advance how it will turn out. I tried to see from the size of the spot on the bottle if one or other is obviously closer to the lamp–I can’t– but what really matters is the thermocouple, of course. The NOAA description in “its a gas, man” looks like the epitome of careful research in comparison.
This is just kid science. The BBC did their best. Not as good as the ten-year old of a couple of weeks ago, though. It is funny that the journalist sells this as “proof” of global warming early in the sequence.
Bryan C points out some problems with statements by Professor King, who joined the group after the CO2 bottle experiment was performed. Here is his comment, continued.…........................
Professor King adroitly avoided key questions. Anyone there with any knowledge of the science could have taken him apart. The BBC clearly wasn’t interested in finding anyone equipped with the facts who could have countered the orthodoxy. In contrast, we had an ignoramus who expressed scepticism at the beginning saying he was now completely convinced. Others taking part who maintained their scepticism unfortunately didn’t have the facts at their fingertips to back up their positions.
Professor King’s assertions about Climategate (from 6:20) were particularly shocking. He conceded that the behaviour shown was unacceptable, but no conclusions were then drawn by him — the program simply moved on! But I was most stunned by his obfuscatory introduction of the conspiracy theory about “agencies” which went unchallenged, and involved a direct fabrication about mobile phone conversations.
“Remember that these emails go back to 1998 and they’ve been accumulating them and just released them in the week before Copenhagen…
“Let me also make this allegation for the first time in public. It’s an extraordinarily sophisticated piece of work to hack into all of these emails and mobile phone conversations, right? What agencies have got the sophistication to manage that? I leave you to think about that.”
Of course, the most likely scenario is not of an outside hacker but a whistleblower inside the CRU who pulled them together and released them. The suggestion of “an extraordinarily sophisticated piece of work” doesn’t really hold up if you’re just referring to emails, but introducing the idea of monitoring mobile phone conversations (a complete lie as far as I’m aware) serves to boost the conspiracy theory and muddy the waters. And this man was Britain’s most senior scientist?
I hope you can draw people’s attention to this deception!
Bryan C of the UK.
