Not at all !
You can take a hypotheses, then run right out and find evidence to prove your
beilefe;
- Look at the " OJ Jury "
- Didn't want to believe he was guilty, so they found the evidence that
went along with their belief.
& then called everyone else " Prejudiced ".

Nobel winning scientists are repeatedly bamboozled by Hucksters,
Frauds, sleight of hand artists;

Variations occur naturally over time; that has never been in
dispute. However, the physical properties of CO2 are very well known,
and we're adding a lot to the atmosphere every year.

An interesting Idea:
- Ocean's general warming trend is killing off Coral, which usually absorbs
& Builds calcium Carbonate exoskeletons;
- But with the corals dying out, from their environment warming slightly,
the C02 the coral would have absorbed is still
in solution in ocean water, absorbing heat from the sun ( etc)
slightly expanding the volume of the Ocean, hence Slightly raising sea levels..
( ! ! ! )

It would be nice if some natural process is cancelling out the
effects of all that extra CO2. I hope it is, for our sake, but having
a closed mind to the issue isn't going to make it go away.


Anyway, does anyone know if higher average temperatures will have
any effect on shortwave propagation? Or other frequencies, like
Sporadic 'E' in the summer?


Now; if the overall atmosphere Does warm by a slight amount,
it will expand in volume ( right ?? )

- So we might surmise that the upper parts of the atmosphere would be displaced
Upwards..
accelerating the decay of low earth orbit satellites;
and possibly raising the absolute elevation of the Ionospheres reflective
layers..
not a " 1 + 1+1 = 3 "
or Correlation = Causality
but
- an interesting Idea...
