When discussing CO2 caused climate change, one must always tie the observation back to the only defined mechanism by which CO2 can affect climate change. The only defined mechanism by which CO2 can impact the climate is through the Greenhouse Gas Effect. The Greenhouse Gas Effect as it relates to CO2 is the thermalization of LWIR between 13 and 18µ, this is it, that is the only mechanism by which CO2 can affect climate change. CO2 can only cause warming, warming caused by the vibration of the CO2 molecule due to the absorption of LWIR between 13 and 18µ. I repeat this over and over and over because this is a science, and as a science, you have to isolate the cause and the effect.
With that understanding, we will now discuss the introductory graphic. The introductory graphic shows the temperature measurements over the past 100 years. A blue circle is a location that cooled over the past 100 years, and a red plus location warmed over the past 100 years. 1/3rd of all locations in the lower 48 cooled over the past 100 years. Why then isn’t the fact that 2/3rds of all temperature stations showed warming proof of CO2 driven global warming?
2/3rds of all locations showing warming is evidence that those locations warmed over the past 100 years, it is far from evidence that CO2 caused the warming. Why? Because CO2 is evenly distributed throughout the atmosphere. Currently, CO2 is 400 ppm at the locations that warmed, and 400 ppm at those locations that cooled. That condition existed throughout the past 100 years. Because this is a science, and because it is a science and not witchcraft you have to be able to explain how a change is CO2 can explain a warming in one location and a cooling in another location just down the street when both had equal concentrations of CO2. Because CO2 is a constant across the globe, CO2’s only effect on the temperature graph would be a parallel shift, not a spike here and a dip there, that isn’t the impact thermalizing LWIR between 13 and 18µ would have.
The other problem is that H2O dominates the lower atmosphere, CO2 literally has zero measurable impact. All ground measurements are located in the layer where CO2 has no impact. The CO2 signature isn’t even noticeable until about 3km up in the atmosphere where H2O has precipitated out. To identify CO2’s impact on the lower atmosphere, you have to control for all other factors like H20 and the Urban Heat Island Effect. To do that, you have to look at Antarctica and Antarctica hasn’t warmed over the past 50 years.
The fact that climate alarmists rely on ground measurements to make their case of CO2 caused climate change demonstrates an ignorance of biblical proportions. Satellite measurements measure the proper layer of the atmosphere to identify the CO2 signature and satellite temperatures show a clear relationship with the oscillations of the oceans, not CO2. If that is the case, you have to explain how LWIR between 13 and 18µ can warm the oceans. Spoiler alert!!! It can’t. UV and Visible light warm the oceans, not LWIR.
