How accurately do the man-made global warming models predict future climate temperatures? Is there any statistical significance to the predictions?
The burden of proof is on the man-made global warming alarmists. They are the folks who want to spend huge amounts of money to fight the phantom menace, so they have to prove, beyond a reasonable doubt, that global warming is occurring, that man's activities are causing the global warming and that their solution, getting all of our energy from renewable energy sources, is the most cost effective solution to the global warming problem. So far, I don’t think global warming alarmists have met any of their burden of proof.
If global warming was a scientific theory without a political program attached to it, it might be easier to believe that its proponents were not cooking the books. However, when you read something that says initially the data didn't fit the hypothesis, so the data was adjusted, it tends to lessen scientific credibility a lot. That's exactly what this sentence says: "
The cost of changes that the alarmists want to impose is staggering. In the US, 33% of our electricity is generated from burning coal. To meet the Paris climate goals, we will probably have to scrap all coal fired generators. This represents trillions of dollars in investment. Another 33% of electricity in the US is generated from burning natural gas. Mean green organizations want all of these generators closed as well. The US gets 20% of our electricity from nuclear power. Almost all nuclear generators in the US are over 20 years old. Over half are over 30 years old. The number of nuclear plants decommissioned in the last several years easily outnumbered the new nuclear generators.
Assuming that any global warming we see is man-made, the answer is nuclear power, which emits no carbon at all. But alarmists don’t like nuclear power. Assuming you don't like nuclear power, then we have to build a lot of dams, probably killing a lot of snail darters and other endangered fish. We also have to carpet sunny places like Death Valley with solar collectors without regard to the possible extinction of obscure lizards. We also have to build wind turbines and kill literally tons of migratory birds and ruin the view from Martha's Vineyard. We also have to build a lot of high voltage transmission lines through everybody's back yards to move the renewable power from where it’s generated to where it’s used. But the environmentalists, who fervently believe in global warming, fight all of these things.
Assuming you don't like any of these options, you have to assume a miracle happens in order to stop the carbon. Or we can go back to 19th century technology and live in an Amish paradise. I’ve personally mucked out barns. Horses have a major pollution problem. The expense of all of this gets obscene. The flimsy justification for the economic ruin that the fight against global warming will cause, is a statistically insignificant anomaly. Good luck with the politics of flimsy justification, miracles and economic ruin!
