You may have said that, but the "scientists" that depend on this to make their living are saying that 50% of the warming is due to the activities of man.
This means that CO2 is half of the driving force and all of the other 50 or so factors, including the Sun, make up the other half.
No, that is not at all what that means. You are missing basic concepts here and I'm not sure how to explain them. I'll give it a shot, though.
Factors A, B, and C all influence the change in Widget Production. All conditions "standard," 100 widgets are produced.
A is the biggest factor. From its low to high oscillation, Widget Production shifts +/- 50 units.
B is the next biggest. From its low to high oscillation, Widget Production shifts +/-20 units.
C is a small variable. From its low to high oscillation, Widget Production shifts +/- 5 units.
From 1950 to 2000, Factor A goes from its baseline and falls to 10% of its maximum "down" oscillation. Net result: -5 units. (10% of its maximum oscillation of 50)
In the same period, Factor B goes from its baseline to 100% of its maximum "up" oscillation. Net result: +20 units.
In the same period, Factor C goes from its baseline and falls to its maximum "low" oscillation. Net result: -5 units.
The end result is only + 10 units. Factor B could clearly be said to be driving this shift, as the other factors are actually resisting this trend. That doesn't mean A has suddenly become unimportant, its oscillations are still going to have a major influence on things. Why, who knows, over the next few years it could swing way down and completely erase the progress that B has made. Stranger still, Factor C turned out to have the same effect as Factor A, -5 units, despite it being the smallest of the three variables. This is because it fluctuated a lot from the norm while Factor A did not.
This is the deal with temperature. We'll call Factor B the green house effect. It has been steadily increasing for more than a century now. However, Factor A (the sun), has oscillated up and down quite a bit. This has the effect of temporarily halting the rise in temperature. And then boosting it. And then halting it. And then boosting it. But the
overall solar influence on the
change in temperature has been small, because the sun just hasn't changed much in the last 50 years. Its oscillations have been pretty regular up until this latest cycle, which dipped down lower than before. And sure enough, this caused the temperature rise to halt.
So, pondering it, the basic concept you're missing is the
net change in any given variable being key. The sun is very, very important to temperature. It just hasn't been doing much, allowing the influence of CO2 to show.
