No, no, you just don't get it Jimp! As warm air rises it expands and 
cools UNLESS there is man-made CO2 in the atmosphere in which case the 
air can do anything you SAY it does. Especially if it furthers your 
political agenda. That's why they call it "climate change" because the 
story constantly changes.

Sorry gliber34, but the term "Global cooling" is not out of fashion 
along with the later term "Global warming". Today it is only politically 
correct to say "Climate change'.

Is Climate change like an Oil change ?

Get rid of the old used Climate, and replace with new ?


like Wormleys new hot air rising into old cold air ?

Old and new has nothing to do with that.

Hot air raises, because is less dense due buoyancy,
and cools itself* down while expanding due adiabatic effect.
It the opposite effect than when a bicycle pump get hot
while pressurizing the tyres.

* aside of slow thermal transfer with surrounding colder air
