For myself, I kind of wonder how some go so far off the beaten path to tout their suspicions that are sometimes way off base.

That's a refreshing viewpoint. From
NASA's site on climate change:
There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause.

Sun’s energy output per second[ ≈ 3.8 x 10²⁶ joules.
Total energy consumption by humanity (all time) ≈ 10²³ to 10²⁴ joules.
The Sun produces more energy in a little more than one second than humans have ever generated or consumed in all of history.

I have a sizeable piece of aluminum on my lanai. On bright, sunny days it is hot to the touch while on cloudy days it is just warm and at night, without the sun, it is cool to the touch. Clearly, all that energy from the sun is having an effect. However, add a little fossil fuel and the piece of aluminum will get hot enough to take the skin off my hand. No matter how large the contribution from the sun, a little man-made input can make a difference.
I have not seen one comment ever that denied paleoclimatology or Milankovitch cycles. I have not seen one comment ever that claimed that the only influence on climate was man made. Y'all want to argue that size matters and yours is bigger than mine but no climate scientist claims otherwise.
