I concur with Bill McAllister’s letter “The climate-warming game” (5/28). I, too, am an engineer — for some 60 years. For 28 years I taught and conducted research in the area of gas dynamics in a university aerospace engineering program. My research included the development of a laboratory model of a tornado.
There are six equations that describe a gas dynamics problem: the equation of state and five nonlinear differential equations expressing the conservation of mass, momentum and energy. Key to these for the atmosphere are: 1. the future flow of heat from the sun as a function of time and space and 2. the absorbent and reflective nature of the atmosphere as a function of time and space.
We don’t have a clue about these. For any computer model to produce answers, many extremely questionable assumptions must be made. As McAllister noted, “why can’t the current scientific models accurately predict next week’s weather?”
The new green left (environmentalist) propaganda reminds me of the old red left (communist) propaganda. The dirty word is now carbon rather than capitalism. The game is simply to intrude and control everything. How much will the carbon tax be for each of us to breathe?
