Well, OK. We don't directly control the amount of water vapor evaporating from the world's oceans and then condensing and returning to earth in the form of precipitation.ohio jones wrote: ↑Tue Jun 13, 2023 11:36 pmI am not in the habit of "spewing" CO2 into the atmosphere, but don't these statements seem contradictory?... every ton of CO2 that we spew into the atmosphere causes some additional amount of water to evaporate ...
But we do indirectly control it by adding other greenhouse gases to the atmosphere like CO2 and methane. I will concede that point.
As for the word "spew"? That is an accurate description of what you do when you drive a car or truck or tractor. The exhaust spews CO2 into the atmosphere. The average car emits between 0.4 and 0.5 kg of CO2 per mile which is about 10 moles of CO2 in chemistry terms. At standard temperature and pressure any gas has a volume of 22.4 liters per mole. So 10 moles of CO2 equates to volume of pure CO2 of about 225 liters which is slightly more than a 55 gallon drum. It would actually be a bit more than that since standard temperature is 0 Celsius. It would actually closer to 65 gallons on a hot summer day, but call it 55 gallons for the sake of visualization.
So every mile you drive you put out another 55 gallon drum of pure CO2, day in and day out. If you are driving at 60 mph that means you are emitting a 55 gallon drum of pure CO2 every minute you drive. And if you drive a big truck SUV, bus, or tractor it is of course much more than that.
Every one of these cars on every highway in the country is putting out a 55 gallon drum of pure CO2 for every mile it drives, day in and day out. If that isn't spewing, I don't know what is.
