The "Little Ice Age" and its included climactic minima is often partially attributed to an extreme solar minimum. In particular,

During the period 1645--1715, in the middle of the Little Ice Age, there was a period of low solar activity known as the Maunder Minimum. The Spörer Minimum has also been identified with a significant cooling period between 1460 and 1550.[69] Other indicators of low solar activity during this period are levels of the isotopes carbon-14 and beryllium-10.[70]

Little Ice Age

Now, a new model of solar behavior which is producing shockingly accurate predictions with respect to the sun's 11 year activity cycle predicts an extreme decrease in solar activity during the 2030s.

Less incoming solar radiation equals less heating of the earth and its oceans, hence a period of cooling. The greenhouse effect really changes none of that, except that the effect both amplifies and prolongs the heating caused by incident solar radiation. (The radiative cooling of the Little Ice Age might today only result in a decrease in the rate of heat gain instead of actual net cooling.) The new model, which involves adding a second "dynamo" to the existing model, suggests a 60% decrease in solar activity during the 2030s. The discoverers are predicting another "Maunder minimum" which, should it happen, just might give us a little breathing room, which we will probably desperately need by then.

As you divest from carbon, you might wish to invest a small portion of the proceeds in woolies and sweats. The way things are going, I can't help but hope that they are correct. One way or another, we shall know relatively soon.
