Credit where credit is due. This graphic was developed by Warren Meyer using Anthony Watt's analysis (Watt's results shown below).
Everything you need to know about the cause of global warming is right here. The raw measured temperature data for the last 120 years show a cooling trend. Only after the global warming fraudsters adjust this data to match their theories and models does a "Global Warming Trend" emerge.
This brings me to that warning at the end of the late Michael Crichton's State of Fear:
WARNING: COMPUTER SIMULATION - MAY BE ERRONEOUS AND UNVERIFIABLE
There is no physical evidence of anthropogenic global warming. All the panic being generated by Al Gore, James Hansen, and Obama's Energy Secretary Steven Chu is based on computer simulations. Simulations using certain specific positive feedback assumptions with no factual physical basis.
(I)t sounds like they went out and measured something. Actually, they just ran a simulation. They talk as if simulations were real-world data. They're not. That's a problem that has to be fixed.Frankly, it is even worse than what Crichton wrote. "They" (meaning the Global Warming Industry) cannot even be trusted with the "real-world" data. It is just something to manipulate to confirm their models and simulations.
Even anomalous and physically suspect measured data passes through these alarmists without critical analysis. They have a vested interest in promoting a climate change panic. Their jobs depend on it.
One further note. The graphics in this post use only U.S. temperature data. The data from most of the rest of the planet is even more suspect and show greater global warming. Quality control cannot be confirmed in many of these nations. But more significant is the fact that many of the nations "producing data" showing an anthropogenic global warming effect will be the beneficiaries of significant economic gain if the United States is handcuffed by restrictions on greenhouse gas emissions.
