Ned and Karl often run into people on twitter who tell them that their ‘theory’ violates the 1st Law of thermodynamics. Firstly, as Ned points out, their empirical work is not a theory, but a discovery. But let’s allow Paul to develop his argument, and then we’ll pick it apart and see if it ‘holds water’.

Paul Alter@PAlterBoy1 writes: I wrote this up with the help of a physicist and a climate scientist. You have a gas in a cylinder with a piston. Kinetic energy is applied to the piston. The piston adds energy to the gas through its work: the work by a force is the force times the distance the force (work).

2/ point is moved into the direction of the force. The piston exerts a force on the gas and when it moves to compress the gas it “works” and hence adds energy. The energy that the moving piston adds to the gas is converted into heat, to the effect that total energy is conserved.
