this article is responding to the strawman argument that the clear historical correlation between solar output and temperature - which is extremely robust, and has nothing to do with the maunder minimum - is a consequence of tsi, which is something that no solar scientist has ever suggested. and, in fact, the science around climate change takes this as a given; the purpose of the ipcc reports is to separate anthropogenic signals from the sun, and the ultimate argument in the end is that the warming can't be caused by the sun because it is dimming.

rather, it is well understood - and i've posted dozens of articles to this site - that the mechanism underlying the correlation has to do with ultraviolet radiation, not with tsi. it is essentially a magnetic phenomenon that alters the jet stream by messing with the atmosphere.

so, you don't want to think about it like you're turning the heat down or something. rather, you want to think about it like you're moving magnets around on a sphere, with iron filings inside of it. as you change the way the magnets are oriented, you change the way the filings are arranged, and this is what we're seeing with the jet steam in the northern latitudes. but, this is something that you need a basic understanding in physics to understand - it is not intuitive and not easily explained to scientific illiterates.

as i've stated here repeatedly, this will probably not change the overall average warming trend. we can't really state for sure, but it's a question of rates - we don't think the sun is slowing down fast enough to overturn the accelerating rates of global warming. it could, though. science operates in a realm of probability and uncertainty, not in a realm of absolute knowledge or dominant fact.

but, if the sun maintains it's current trajectory, and you live in the northern hemisphere, what is being called "global warming" could turn out to be rather disappointing, as we enter a period of extended minima that frequently pushes the jet stream to the south.
