re: #147 LudwigVanQuixote

I read your posts…And you prove that CO2 is a greenhouse gas…I didn’t say it wasn’t.

So you don’t believe that burning fossil fuels on an industrial scale releases gigatons of CO2 into the atmosphere? Where is this CO2 coming from then. We see it rising by huge amounts in the industrial age.

How do you know that it didn’t rise to high levels BEFORE the industrial age? During the middle age warming period, the end of the ice age?

We see huge (concentrations doubling) CO2 changes 30,000 years ago, long before the burning of fossil fuels.

Please look at these direct optical measurements of it.

The direct optical measurements seem to start in 1960. If I showed you a growth chart of me since 1960, you would assume I was going to be 30 feet tall by now. They try and estimate levels before that… but they don’t know.

Do you believe that these rising carbon concentrations occurred ex-nihilo?

Now you are showing that you didn’t read my post. I was perfectly clear where I thought rising carbon concentrations occurred from.

Now the sun does warm the planet. When sunlight hits all that CO2, the CO2 gets warm and the atmosphere gets warm.

Is that the only thing that happens when sunlight hits the planet?

Anything else? Or is the planet really that simple.

Please see my posts 28 and 29 for a complete explanation as to why.

I did, and you explained how CO2 holds in heat very well. However that is not really the subject is it? Before you spend billions of dollars, wreck the economy, and force huge changes to everyones life you need to prove that changes in the climate are not a natural cycle that the planet does despite us.
