Yeah. Like the kind of feedback clouds provide. Not the fact that

Unsubstantiated assertion. Correlation doesn't necessarily imply
causation.

However, in the case of AGW, a very plausible mechanism of causation
is known. Do you have another, more plausible, reason for the
correlation? If so, present it. If your argument is solid, you'll
definitely get a Nobel Prize for that.

I don't think there is any question that global temperatures have risen:

But I have a bit of concern for honesty here. They say, "The last four
years rank among the five warmest Januarys on record."

That's true ... as far as it goes, but the chart shows the last two years
in a downward trend, taking off a third of the temperature increases over
the last 138 years!

Weather is VERY complex, and modeling is VERY difficult, particularly when
certain factors are handled only indirectly (and, therefore, only approxi-
mately) and other factors haven't been included.
