Every 7 years there is a river in Colorado that reverses it's direction for one day. Scientists are still puzzled why this happens. The river is extremely flat and has high banks. The best theory is that there are underground reservoirs downstream that build up pressure over time, and when the upstream water source hits a cyclical low, the downstream pressure overcomes the upstream source and the water runs backwards until the pressure drops in the downstream underground reservoir.
That's a true story that I just made up. I dedicate it to Moray and the other global warming freaks who cherry pick data collected without consistent methodology over the last thousand years to "prove" that man-made CO2 is the most significant factor in global temperature changes over the last couple decades. And for those who skipped thermodynamics in school, if you melt ice in hot tea, the net energy of the system (original ice plus hot water) remains the SAME. The ice got warmer, the water got colder. There is no net change in energy, it's just spread out a little differently. So quit using that retarded analogy because it makes no sense except to the ignorant or deliberately deceptive.
You're way under V sub mca.
Why you've chosen to reference my name to something I've never said, equating climate to a glass of tea and an ice cube, i'll never know. I've never said anything of the sort. As well, I'm not a GW freak. I simply present the science as it stands.
You are correct in your thermodynamics lecture...net E state is neutral in your example. The difference in you ideology is.... the planet is not a glass of iced tea. Figure it out below.
Thermodynamic systems
Energy transfer is studied in three types of systems:
Open systems
Open systems can exchange both matter and energy with an outside system. They are portions of larger systems and in intimate contact with the larger system. Your body is an open system.
Closed systems.
Closed systems exchange energy but not matter with an outside system. Though they are typically portions of larger systems, they are not in complete contact. The Earth is essentially a closed system; it obtains lots of energy from the Sun but the exchange of matter with the outside is almost zero.
Isolated systems
Isolated systems can exchange neither energy nor matter with an outside system. While they may be portions of larger systems, they do not communicate with the outside in any way. The physical universe is an isolated system; a closed thermos bottle is essentially an isolated system (though its insulation is not perfect).
Why a college educated, line officer doesn't see the difference... I shudder to think.
