The perfect subject for a discussion --Hot Air

 Our PM and her mates somehow developed the view that hot air concerns were something simple that she could discuss with the public- how could she get it so wrong ? It seemed to them last week that it was pretty simple ---so  that maybe is where the problem still lies.
To have a good discussion you have to limit the points to something that's simple. Something that has clear boundaries  and is easy to visualize.
"Air is really pretty simple" ( only largely N,C O H Ar ) Tick that
" Warming is pretty  simple "  ( we all experience that every day ) Tick that
"Global warming is pretty simple" tick that   "Fossil fuels heat up our our homes and engines so why not our atmosphere"  It all makes sense , simple sense to most people. Tick
Check.  Best of all there will be no unexpected arguments against what we say because you can't see any of the things we are talking about . Perfect
"Not only is radiation  invisible its divisible and so is air . Even if we are wrong ,its going to be very hard to prove us wrong . Our bloke knows more air than their bloke and no one in the media wants a long debate nbout things they can't see . It''ll be  fun and ,  no way we can lose - we have picked something too deep for us and too deep for them ---- to top it off " it looks simple "---- if you want to see it that way " Big tick
Real Science stuff on the atmosphere is awe fully boring because anything to do with organic chemistry , fluid dynamics and radiation  is really complex let alone together .
Lucky for polys the key elements are invisible and  highly divisible
---AIR Look at the forces acting on it ; downward there is weight , and horizontally drag at the lower boundary and inertia right through to the top ; Turbulence throughout creating layers and eddies. Mountains push it up and carry water with it  in all sorts of forms that drastically change the radiation and reflection patterns over every square inch of earth.  

HEAT energy from the sun manages to heat up one edge of this turbulent flow in a way which is greatly influenced by the amount and height of water in the atmosphere directly above it .Meanwhile,  the wind blows and carries the complexity all ways
ALL TOGETHER  -lots and lots of different types of  radiation running largely through the air  and in changing ways each day and season  .
- and every day and in every place the effect of water from the surface has an impact on whose talking to who
- on one boundary users of NCOHAr are acting against the laws of  physics by using up some of the air contents in a way that is mind bogglingly complex.
I am not confused or committed to reducing Co2 . The greenhouse effect has never been properly demonstrated and most long wave radiation we produce is most likely being lost to space. Doesn't stop people thinking otherwise.
Not easy to see whose bumping into whom and what they are saying when they do .   More here  Copyright riskwithin
