Hi Sean, thanks for the read and response.

I’m no expert, but from what I’ve read, the logarithmic/diminishing effect of co2 means that as co2 concentrations get higher, their effect upon temperature progressively diminishes.

According to Anthony Watts’ site: “This diminution effect is probably the reason there was no runaway greenhouse warming caused by CO2 in earlier eons when CO2 levels were known to be at levels of several thousand ppm”

The fact that water levels were higher in “ancient times” doesn’t necessarily concretize your case either, if co2 levels were the same then, why are water levels not that high now?

And interestingly, during those “ancient times,” around 180 million years ago, CO2 rose from about 1,200 ppm to 2,500 ppm. Interestingly, over this period, the temperature also decreased from 72 degrees to 61 degrees.

I’m no expert, but this prompts me to wonder just how large a role co2 plays in the temperature, how multifaceted, and complex the climate may actually be.

And then there’s the argument that the environment actually thrives under higher carbon conditions, and is responsible for the greening of the earth.

This is why people like Elon Musk say that some additional co2 mightn’t be the worst thing for us or the planet.

Given that cold climates are magnitudes deadlier than warm climates for humans, perhaps it's preferable that we ebb among a slightly higher temperature anyway.
