I can show you how carbon dioxide affects earth’s climate using this heat sensitive infrared camera .. a candle, this glass tube .. this canister of carbon dioxide gas ..
.. the camera picks up the flame perfectly. The hot spots are glowing white ..
.. When I turn on the carbon dioxide .. the carbon dioxide in the tube is effectively trapping the heat. The candle’s warmth no longer reaches the camera. Instead it is absorbed by the carbon dioxide inside the tube ..
.. what motivated Stewart to screen the demonstration ..
The question raised by that demonstration is the one that Geezer couldn’t answer Quote .. what motivated Stewart to screen the demonstration .. I’m interested in that question too and trust that it is acceptable to the thread moderator to try to answer it here.
I can show you how carbon dioxide affects earth’s climate
I believe the one thing that remains contentious point is if if the presenter's claim that:QuoteI can show you how carbon dioxide affects earth’s climate is adequately explained by the experiment
No, the camera picks up only a very small part of the flame’s emissions
No, it is the filter that is trapping most of the candle’s heat, not the CO2, so that is why the most of the flame’s emissions don’t reach the camera.
Pete, How would you demonstrate to a lay audience that CO2 absorbs IR?
.. TV science isn't real science- its dummed down for an audience who are not experts in the field ..
Why do you think you should 'bring it over'? Unless it's a completely separate question (which it appears not to be) it should stay in the original thread. Reiterating is not likely to get an answer any quicker & flies in the face of the site's AUP. I think you can expect to find the two merged quite quickly unless you can justify your need to start a new thread on the same subject
.. in this thread please stick to the question at hand, which is about the youtube video you posted. I will lock this thread if you keep using it to .. editorialize about other topics..
