The first law of thermodynamics is often called the Law of Conservation of Energy. This law suggests that energy can be transferred in many forms but can not be created or destroyed.
For the sake of argument, let’s assume those that believe CO2 is adding energy to the system are correct. Okay, how much? We have a gas that is .04% of the atmosphere that increases 1.5 ppm yearly and humans contribute 3-5% of that total yearly, which means the increase by humans is 1 part per 20 million. In a debate, someone argued just because it is small doesn’t mean it is not important. After all even a drop with 0.042 gm of arsenic could kill an adult. Yes but put the same drop in the ocean or a reservoir and no one dies or gets ill.
Then there is the energy budget. The amount of heat energy in the atmosphere is dwarfed by the energy in y the oceans. Trying to measure the changes from a trace gas in the atmosphere, if it were shown to definitively play a role in change (and it never has), is a daunting task.
NASA satellites suggest that the heat the models say is trapped, is really escaping to space, that the ‘sensitivity’ of the atmosphere to CO2 is low and the model assumed positive feedbacks of water vapor and clouds are really negative. Even IPCC Lead Author Kevin Trenberth said “Climatologists are nowhere near knowing where the energy goes or what the effect of clouds is…the fact is that we can’t account for the lack of warming at the moment, and it is a travesty that we can’t.”
