Everyone knows that the Earth's climate is controlled by the amount of CO2 in the atmosphere, not by the sun. Just ask Algore.

Well, I suppose two out of three assertions backed by proof isn't bad.
Prior to the industrial revolution, the sun probably accounted for about 10 to 30 percent of climate variability, Hathaway told SPACE.com, but now that greenhouse gases have started to build up, "the sun's contribution is getting smaller and smaller," he added
with a notable lack of quantification.
But the sun isn't the only thing that influences our climate: volcanic eruptions, large-scale phenomena such as El Nino, and, more recently, the accumulation of greenhouse gases in the atmosphere also affect the global climate.

Well, which is it, young feller? Is you a solar physicist, or is ya an earth climatologist? Seems to me you may be carrying too many significant digits on that magic sliderule of yours.
I think that my statements conveyed, with the implied range of estimates, the contributions of solar variability and internal variability to total climate variability, as currently assessed by climate scientists.

This clown is either a glib liar, or a moron.
The sun's contribution is at least 99.9999% and the only "greenhouse gas" that exists is water vapor.
If there is any...
Wow. That’s a very pretty non-answer to a very plain question. Have you considered a career in politics?
I do know this: the sun is giving off very little heat this summer. I am usually somewhat tanned by now, but this year nothing but winter pallor. The native foliage is way behind schedule, what wasn’t killed by last week’s frost. It doesn’t look all that good in the garden either. We have 55 and it should be 75. High temp so far was 72 last week one day about 2 PM.
The numbers aren’t really statistics. The estimates stated are consistent with other estimates that have been stated previously. If that constitutes defense, so be it. I have not seen information that indicates the estimates are seriously in error.
Simple observation of the climate effects caused by the Mount Pinatubo eruption falsifies the above statement, irregardless of any examination of anthropogenic forcing factors.
The only outside source of energy is the sun.
The only other source of energy is orbital/rotational friction, which has to be very small, by comparison.
The effects of volcanic erruptions are short; rarely last longer than 8 months, while sunspot cycles are 11-17 years.
The current lag in sunspots has measurably reduced IR, while allowing an increase in UV due to the reduction of water vapor from the reduced IR. This isn’t new.
Irregardless is not a word in our language.
Cogitator, the sun is the sine qua non for earth's climate (and for all life on earth to exist). To claim, therefore, that the sun is only responsible for 10 to 30% of earth's climate variability (as you and Hathaway do) brings me to...
Definition Two — Folly: a lack of understanding; foolish belief.
Citation? My references indicate that satellite data show an increase in atmospheric water vapor.
So sue me for not using a word in "general acceptance".
The realization that you don't understand. If the Sun didn't vary, it wouldn't cause climate variability. Under that circumstance, climate variability would be solely due to factors internal to the climate system.
Howver, because the Sun varies a little, a small part of the observed total climate variability is attributable to the variability of the incoming solar radiation.
It's not that hard a concept. And it's not a foolish belief.
Vineyard was referring to Al gore being a ‘C’ student; at least until he flunked out of divinity school.

This statement cannot be true.
Why not?
Its a double negative.
If its without a lack of regard, then it must be with regard ;o)
