I have been reading them. Some of them correlate reconstructed changes in solar activity to reconstructed changes in climate. They also correlate volcanic activity to changes in climate (cooling).
None of them seem to say that the current warming trend is caused by changes in the Sun.

Because this guy (Bill Nye) is the mouthpiece for millions of uneducated people that take his word as gospel and don't even question it. That's why you should care.
If you point out a flaw in his ridiculous logic/argument, you're ridiculed.

Well if you and Phage are alive in 30 years time you will be able to have a good discussion about this with some good data showing the effects of a solar minimum (if we indeed enter one).
I can mediate if you like
If you are implying that increasing CO2 levels are the result of warming oceans I would have to point out that there is much evidence to the contrary. But like ENSO, the AMO is an internal phenomenon whereby the oceans periodically retain heat from and release heat to the atmosphere. Both represent spikes and dips set against the warming trend.
The AMO (Atlantic multi-decadal oscillation) is rarely discussed along with oceans temperatures and the effect that has on its CO2 carrying capacity.
Actually, it doesn't discuss forcing. What it does is cast doubt on a relationship between solar activity and the current warming trend.
Here is an interesting paper that discusses Solar forcing and CO2.

Although the solar activity during the last two solar cycle has a deep minimum there is a global warming, the variations in solar activity do not seem to play a major role in determining present-day observed climatic change. Prevalent global warming, caused by building-up of green-house gases in the atmosphere, seems to escalate and hence mask this solar effect.

Here's another.

Correct. But internal processes do not change the physics of radiative forcing. The heat retained due to increased forcing gets hidden in the oceans for a time (through processes we don't fully understand) then is released to the atmosphere. But it doesn't go anywhere because forcing keeps it here. AMO and ENSO present as spikes and dips in the warming trend.
Warming and cooling seem to be driven by a dynamic and multi-faceted system that we just don't understand.

I don't think geomagnetic drift has much influence on global temperatures or climate.
Are you saying that air molecules are affected by magnetism?
