Quote:So if Baldimo is right about the effect of CO2 on heat retention being in doubt, all those farmers could have been wasting a lot of money over all this time. Baldimo should advise them to stop pumping CO2 into their greenhouses' glass walls and see what happens.
I pointed out to him that:
1. Greenhouses do not get, or stay, warm because CO2 is pumped into them. If you want to see the greenhouse effect, lock your puppy up in your car on a hot day and leave him there a few hours. No extra CO2 required.
2. Techincally speaking, CO2 does not "retain" heat. It radiates it, and some of that radiation heads back to earth, further warming it.
No one (and that includes the guy I quoted--at least to the extent I quoted him) claimed that C02 does not contribute to warming. The issue was about the mechanics (i.e., how, NOT IF) pertaining to the manner in which CO2 did this.
