We see in SunsetTommy's Signature two ideas/'truths' meant to show it isn't falsifiable and is therefore Not a Valid theory/truism.
But Of course, it is Falsifiable, and the two statements above do Not necessitate any conclusion.
Saying so is a non sequitur.
If ie, we hugely cut our emissions as a planet, and GHGs returned to what they were before man drove them up: (ie, CO2 50%/280-420; or Methane 3x,) and the warming didN'T gradually stop and even reverse, that would discredit the theory, BARRING other factors as the many Solar Cycles (Milankovich etc).
Because no one is claiming that it can't get cooler IF Weakening of Solar Forcing (earth tilt changed, or distance increased cyclically) (or a La Nina, etc) overrode it due to any event - foreseen or unforeseen - just that Man IS causing it to warm with these Aptly name Greenhouse gases. And if a weakening of the sun cooled it, it would still be warmer than it would otherwise have been due to our thicker GHG blanket.
In fact, the theory continues to be Validated (which is how science works). Theories, like Evo, Atomic, etc do not get Proven. (A 'God' could always pop up and say he is the cause of anything.)
Scientists have already tested this by directly measuring Solar energy hitting earth, and shown that is has NOT Changed in 50+ years... UNLIKE what has caused ALL the other warming/cooling cycles.
They have also measure solar energy being Reflected back out into space, and it is being Blocked/Trapped at the exact spectral wavelengths of - again - (the aptly named) Greenhouse Gases.
That/those two is one of the biggest reason we know.
