I have many good friends who are ACGW (Anthropogenic Catastrophic Global Warming) believers. I’m not. I was easily persuaded back in the 1990’s that it was real, then I met Lee and was introduced to Roy Spencer and John Christie. They produce this product above. Technically done by the University of Alabama, Huntsville. It is a NASA product. The National Space Science and Technology Center (NSSTC) is a collaboration center for NASA and UAH, this is their work.
So right off, when they say “This is the warmest year ever!” They are lying in two ways. 1) We know 1998 was warmer, 2) The error bars are +/- 0.2 degrees, so heck, almost any year could be the warmest.
The Goddard product is a little more mushy, but it uses land-based measurements and a huge averaging program that seems designed to cut out cooling areas and replace them with “average warm” areas. But Frankly, even with their thumb on the scales, this is it. This is the scary warming.
Do Humans influence global warming? Probably not, or only at the margins. (A 0.1 degree increase may have occurred due to human influence- the addition of CO2 to the atmosphere, however, the margin of error is still in the +/- 0.2 degrees C region, so we can’t really know.)
Is it a Catastrophe? Nope. Mild effects, entirely beneficial.
Are temperatures going up, up, up? Satellite records say no, some land records say yes, but slowly. We are still below the Medieval Warm Period’s warming. The Roman warming was higher than the Medieval and the Minoan was twice the medieval. The Earth appears to warm and cool by some natural cycle. We would like to attribute it to the sun, but it appears to be more complicated than that.
The problem comes out to: You are going to spend trillions of dollars to fix something that doesn’t need fixing. Some scientists prefer the fixes, because they believe it is good to move to solar and wind power. This ignores the environment destruction that this market imbalance is causing. People die without power. Cheap electricity creates food, clean water, and housing around the world. A Trillion dollars have been wasted on this in the US alone, do you think we got our money’s worth?
