The IPCC considered indirect solar effects at length:
So lets stop misrepresenting the IPCC reports shall we?
The fact is there is no evidence that any of these indirect solar mechanisms contribute significantly to global warming. So that's what the IPCC report.
"There's also the cosmic ray issue. Lower solar winds = higher cosmic rays = more clouds = cooler. Higher solar winds = lower cosmic rays = fewer clouds = warmer. Again, a solar-induced change that isn't reflected in TSI."
That link has NOT been established. Yet you assert it as if it's true! And have the gall to complain about the IPCC's reporting of the science!
Again, none of these speculatory indirect solar mechanisms have been substantiated to affect global temperature in any significant way (or any way in fact). Yet that doesn't stop skeptics asserting that "it must be the sun!" and complaining that the sun is being ignored.
The first thing a scientist looks at for a solar-climate role are changes in the total output of the Sun. Ie the direct effect. Being a huge heat source it's obvious that changes in output will affect global temperature on earth. But it turns out it's output doesn't change enough to explain the warming. So boom, the most obvious influence the sun could have on global warming is ruled out. Yet climate skeptics gloss over this important fact as if it's just a piece of trivia!
Without a direct effect, what's left is speculatory indirect mechanisms that rely on amplification mechanisms. There's no reason that any such thing exists. It's perfectly possible that we simply live on a planet where the Sun doesn't alter enough to cause massive changes in global temperature.
"Nope. TSI - the measurement you like so much - has not dropped in the last 60 years."
TSI measurements don't go back 60 years. Solar activity, as measured by sunspots, has dropped in the last 50 years while temperature has risen. The correlation with CO2 is much better.
Interestingly climate skeptics like to rubbish the idea the CO2 link by pointing at a short recent period on the graph where temperature is flat and CO2 rises. But they completely gloss over the much larger 60 year period where solar output and temperature diverge.
Cosmic rays don't correlate either
No solar metric correlates with the warming. But skeptics aren't interested in lacks of correlation when it comes to non-CO2 causes I guess. Wonder why.
