It is a more complete theory than the concept of AGW, as he actually
has an invalidation criteria. Do you know what the invalidation criteria
is for the concept of AGW? They seem to have left that off.
As it stands right now, there is no standard of data that will
invalidate AGW.
There is a very obvious and simple falsification criterion for 'AGW'; show that atmospheric CO2 and other greenhouse gases don't absorb and re-emit longwave radiation.
Sometimes these things are just so darn obvious that you can't see the wood for the trees, amiright?
Here's another, equally obvious falsification criterion; show that even if it does create a 'greenhouse effect,' CO2's absorption capacity became
saturated somewhere below concentrations of 400ppm.
Of course, we both know these falsification criteria almost certainly won't be met, because the science is based on facts, not speculation. But it takes an extraordinarily special kind of mind to decide that
because these are facts, there is no falsification criterion, and therefore it must be an invalid theory :lol:
Heck if you really want one, here's a third falsification criterion which is at least marginally more plausible: Show beyond any doubt that
some other factor/s are responsible for the overwhelming majority of the observed modern warming, and thus (however likely it currently seems) it
cannot be due to anthropogenic GHGs.
More specific aspects of 'AGW' all have their falsification criteria too - show that hotter temperatures don't mean more atmospheric water vapour; show that hotter temperatures don't mean retreating sea ice; show that water vapour and albedo don't have the effects they seem to have - but I rather suspect that you were not interested in discussing trivial details like that:
You merely wanted to repeat a common 'sceptic' rhetorical point which, as we can see, must have been subjected to all of half a second's thought before being parroted as fact. That's the 'sceptic' way! :lamo
