Just the Gold

Speaking of being in it for the money and the perks, there's this.

Here is my preliminary number:

315 ppmv

CO2 in the atmosphere. This is about the concentration in the 1950s when Dr. Keeling first began his Mauna Loa measurements. That was the first time that the Swiss glaciologists began to notice definite mass wasting in the Alps. Not much. Just some. But basically no countervaling advances.

It has to be made a still smaller value to offset the higher concentrations of methane and whatnot today (and in the future) as compared to the 1950s. I don't know how much less, it is enough that the point is made.

And yes, I do know that the CO2 concentration is currently about 385 ppmv...
