is a good 50 to 60 percent higher than normal...

And makes up what -- 1-2% of total greenhouse gases?

I believe the reference to CO2 being higher than “normal” is eroneous. It has been higher in Earth’s history.

And the argumnt that 50 or 60% more co2 has a greater effect than a tiny change in solar activity is laughable. Similar “tiny” solar changes caused the little ice age because the Sun’s influence is so powrful.
