Radiative Properties of Greenhouse Gases (Video)

 

Here’s another fun video from Peter Sinclair. And his text intro or summary of it:

I’m working on an update of my “The Sun is Doing it” crock – but this one seemed to  want to get done sooner – in time for me to head out to the American Geophysical Union conference for this week. (see more elsewhere on this page)

There’s a persistent delusion out there, that you hear a lot from people who should know better – that global warming boils down to a simple minded correlation between temperature graphs and CO2 rise.  Climate deniers are sure this is true, and that if they just attack the most famous temperature graph, Mike Mann’s “Hockey Stick”, they can knock down the whole thing.

But our understanding of climate is, of course, based not on a graph, but on the radiative properties of greenhouse gases – which have been well known for 150 years, and got seriously nailed during the 1950s when the US government was working on building heat-seeking missiles that had to pick out long wave radiation at all altitudes in the atmosphere.  We realized that CO2 was blocking heat – and as Richard Alley points out here, that means something.

Much more on the scientist in the video, Richard Alley, is available on Climate Denial Crock of the Week (link above) via the Minnesota Post.

    Firstly:-Greenhouses work by preventing convection.
    Secondly:- The 2nd law thermodynamics states :- No process is possible whose sole result is the transfer of heat from
    a body of lower temperature to a body of higher temperature.
    Therefore the “Greenhouse Effect” simultaneously missunderstands how a greenhouse works, and breaks the 2nd law thermodynamics.

    That’s ok then.

      Funny how those physicists don’t understand that.. or how you don’t understand what they are talking about. (greenhouse is an analogy for certain properties in those gases — it’s not saying we have a greenhouse around our Earth)
