Currently, China is producing more pollution and C02 and trash than the rest of the world combined. Add the number 2 offender India and you have almost all the climate change problem that the talking heads are espousing.
But wait, C02 and the temperature were hotter hundreds of years ago. There weren't as many people or cars back then. How do you explain that? I can, it's called cyclical climate patterns that have gone on without man affecting it.
The popular target is the United States, who has reduced it's footprint more than most, but is the bank of climate change to cash in on.
The science says man hasn't affected the climate as much as the AGW play for money says it has. I had to listen to the pontificating by Climatards like Tim O'Reilly and Tom Raftery on this nonsense for years when I was at IBM. I never believed it was anything but a grasp at attention and money. They lead in being wrong on the climate with Al Gore, Greta, AOC and John Kerry, but right on scaring people for money.
The inadequacy of wind power The plan dramatically to cut the combustion of fossil fuels was accepted at the 2015 Paris Conference. The instinctive reac- tion around the world has been to revert to 'renewables', the sources of energy delivered intermittently by the power of the Sun. Unfortunately this power, attenuated by the huge distance that it must travel to reach the Earth, is extremely weak. That is why, before the advent of the Industrial Revo- lution, it was unable to provide the energy to sustain even a small global population with an acceptable standard of living. Today, modern technology is deployed to harvest these weak sources of energy. Vast 'farms' that monopolise the natu- ral environment are built, to the detriment of other creatures. Developments are made regardless of the damage wrought. Hydro-electric schemes, enormous turbines and square miles of solar panels are constructed, despite being unreliable and ineffective; even unnecessary.1 In particular, the generation of electricity by wind tells a disappointing story. The political enthusiasm and the inves- tor hype are not supported by the evidence, even for offshore wind, which can be deployed out of sight of the infamous My Back Yard. What does such evidence actually say? That the wind fluctuates is common knowledge. But these fluctuations are grossly magnified to an extent that is not immediately obvious – and has nothing to do with the technology of the wind turbine. The energy of the wind is that of the moving air, and, as every student knows, such energy is ½Mv2, where M is the mass of air and v the speed. The mass of air reaching each square metre of the area swept by the turbine blade in a second is M = ρv, where ρ is the density of air: about 1.2 kg per cubic metre. So, the maximum power that the turbine can deliver is ½ρv3 watts per square metre. If the wind speed is 10 metres per second (about 20 mph) the power is 600 watts per square metre at 100% efficiency.2 That means to deliver the same power as Hinkley Point C (3200 million watts) by wind would require 5.5 million square metres of turbine swept area – that should be quite unacceptable to those who care about birds and to other environmentalists. But the performance of wind is much worse than that, as a look at the simple formula shows. Because the power carried by the wind depends on the third power of the wind speed, if the wind drops to half speed, the power available drops by a factor of 8. Almost worse, if the wind speed doubles, the pow- er delivered goes up 8 times, and as a result the turbine has to be turned off for its own protection. This is not related to the technology of the turbine, which can harvest no more than the power that reaches the area swept by its blades.
My wife's relatives in Denmark are going to have to deal with this inconvenient truth. They bought the wind farm hoax a long time ago. I don't bother telling them they are wrong. They have to justify living in that place and this is part of it.
Even more for evidence for Tim and Tom, who said both tides are rising and that Climate Science is hard when I asked him for facts. It's only hard if it's your religion and you ignore both the truth and science. Oh look, the tide is the same as it was 1620. Must be that AGW that doesn't change anything.
