Yes. Not just me, actual climate scientists have put forward the idea that the fact that all the models have been running hot for the past 19 year is due to solar variance (claiming it will soon return to normal and validate their models, of course, but they don't model the Sun).
We are as certain as we are of anything climate-wise that solar variation drives the 100k year glaciation cycle of the current ice age. And these changes happen fast, relative to the 100k year cycle. The relative stability of the climate for the past 10k years is an unexplained anomaly in the temperature record (check out the ice core data, if you like looking at real data).
The point is, no one knows why the glaciers have retreated for so long. Where I sit has been under kilometers of ice for most of the past 2.5 million years, with fairly brief ground exposure every 100k years. But the past 10k years were unique in the ice core data - temperatures didn't drop after spiking.
Are we overdue for a massive, rapid drop back to normal? Are we leaving the ice age? In either direction, solar activity is a bigger driver than the CO2 levels we're talking about, and changes seem to happen quite fast: just a few centuries. (It doesn't take much: a 6% drop in solar activity is hypothesized to have caused the "snowball Earth", where the entire Earth, excepting a few geothermal spots, was under ice - the biggest extinction event since the oxygen catastrophe).
