Actually, Galileo was the first person to observe sub spots in the
early 1600s.

I am aware of the correlation between sunspots and their effect on
solar energy delivered to Earth but thought that this had been
dismissed as too small of a change to account for climate change.

On a related note, every abnormal cooling period can be accounted for
by the action of volcanoes (they release sulphur dioxide which causes
the formation of silvery reflective clouds). I just read an
announcement two weeks ago by researchers who discovered an
undocumented volcano which was responsible for the cooling period at
the start of the 1800s.

On a unrelated note, our Sun is 30% hotter now than it was at first
ignition. It will get hotter with time, but that is not the main cause
of climate change. The shape of the Earth's orbit varies from being
nearly circular (low eccentricity of 0.005) to being mildly elliptical
(eccentricity of 0.058) and has a mean eccentricity of 0.028. When the
orbit is nearly circular (like now) the Earth enjoys an interglacial
period. When the orbit is more elliptical we are plunged back into an
ice age. Interglacials average 20k years while glacials average 100k
years. We are warming now primarily because our orbit is almost
circular AND industrialization added GHG to the mix.
Paleoclimatologists tell us that during the previous interglacial when
the average temperature was 1.5 C higher, that the oceans were 6 m
higher. Will this happen again? Talk to scientists in the Maldives or
Seychelles and they will tell you that oceans have risen 20 cm in the
past 100 years. The bad news about that is 1 cm vertical rise
translates into a greater horizontal tide.
