The tone of this post is alot more reasonable than the tone of your earlier posts which implied that recent downward trends of solar output practically disproves solar input to recent warming.

Considering that they've followed fairly close in the past, yes. For example, the 30s/40s can be very easily attributed in large part to the sun. The forcing is obvious.

Is it because of the consensus of scientists?

[/ QUOTE ]
It's just general common sense, the lack of evidence for the other position, the lack of of viable mechanism, the recent divergence, and the known and indisputed forcing properties of CO2. Taken as a whole, it's very hard to have the sun as the culprit.

[ QUOTE ]
As for the recent divergence between solar output and global temperature, can it not be explained by thinking the temperature as a integrator function of solar output?

[/ QUOTE ]
That makes no sense to me. Where is the physical mechanism?

This looks interesting, and different to other graphs I've seen. I'm not sure why they're leaving out irradiance though - that's a crucial component. Give me a day or two to investigate the origin and meaning of this graph.
