The heat at the surface of a planet, is connected to the heat of the planet all the way to it’s center. Because the cumulative total of the heat, when considered in it’s entirety, gravity in one direction is a balancing force, while pressure and heat outwards are the direct reverse to this reaction. This means to measure the average heat, of any given point in the sphere of the journey of that heat, one must be aware, in escalating proportion of all heat and pressure trapped underneath that point. Because at the end of the day, AND in the middle of the day, we know one thing for sure, for every single moment in time, the only immediate fluctuation to any temperature, anywhere on the globe, is the sun’s ability to “slow it down”, trap it. And only in it’s immediacy is it valid to evaluate the impact of CO2, because it can only ever have an immediate impact on earth, in recognition of the tide of back and forth balance of trapped heat, versus ability to trap it. it is traveling within an immediate feedback system.
