We can’t predict climate change


Unfettered Letters
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?”
