See how low the TSI was during the Little Ice Age? And how high it was in the late 1900s?
Where is Dana when you need him?
I went to the highest authority on science, not the scientists, nor the institutions, not even the IPCC, I went straight to the top: Skeptical Science!

They seem to quote real science, with dT's and everything, that say that the current warming cannot be caused by the sun.
I did note that in the IPCC AR5 SPM that the current temperature flat-lining could have the downturn in the sun's activity as a possible cause. Strange it cannot increase temperatures as well.
I am sure that it is not my imagination, but I seem to remember being told for some time that not for nothing was it called the Solar Constant. Consequently, Total Solar Irradience varied so little that the IPCC need hardly consider it at all. Anyway, they were really only concerned with man-made effects not natural ones.
Now the scientists here are saying "we never said that". Can anyone see why there is such a credibility gap between "consensus scientists" and the sceptics?
There are dozens of systems and sub-systems at work that effect climate. At this time most of these systems and sub systems indicate a cooling trend, but the addition of massive amounts of CO2 from industry over the last less than 200 years have changed this equation. The balance of effect has switched to a warming trend as this massive amount of greenhouse gas has over powered other forces that effect climate. While the trend lines move up and down the overall trend is up and will remain up as more CO2 and methane from thawing tundra enters our paper thin atmosphere. While 'the sun' certainly is a major player in this, it isn't the only player. Anyone who simply accepts this simple explanation for a complex set of inter-related phenomena simply doesn't understand how this works.
Who says that the Sun does not effect the climate. There is a very big difference between saying that the Sun is trending in the wrong direction to be the cause of the warming and saying that the Sun has no effect on climate.

Sun affects climate, always has, always will [well maybe not always...there was time before the sun and no doubt will be time after the sun has gone].
In fact the climate is powered by the sun. So changes in activity of the sun will have an effect on Earth. No one who understands even a little science will doubt that.
However other things than the sun can also affect climate and I guess that is where we differ in opinion. The current warming and CC is not being caused by changes in sun activity, there are other factors causing the current climate changes and the biggest of those factors is human activity in the form of changing the composition of earth's atmosphere.
Maintaining a 287K Global average temperature can be a very strenuous proposition, but it's always nice to have water and sun to balance things out. That's what makes our planet so unique.
You should scale your link so it doesn't look so alarming. People might think you are scaling it down too far to make a more alarming point (tic).
Ha! Ha! Look at the two goofballs (Gary F and pegminer)! Looks like they are reeling their lines in. Does this mean that they are caving in to the reality of real science?
Well good. I see that you have asked a question that shows that even the staunchest AGW advocates agree that the Sun can influence the climate.
Good! Now stop taxing CO2! Go tax the Sun!
Nobody says the sun does not affect the climate, that is a lie.
Who are "they"?
Certainly not climate scientists:
NASA:
"Solar radiation is the source of heat for planet Earth."
http://climate.nasa.gov/nasa_role/scienc...
Or the IPCC:
"Solar radiation powers the climate system. "
