I'm curious how the data can be compared reliably seeing as even assuming that all the thermometers used at the turn of the century were perfectly crafted, properly calibrated, cared for properly, placed properly, and recorded properly they STILL would have had an error rate of +-0.5 degrees Fahrenheit. In reality you can almost certainly at the very least double the error rate. Which means that any trends prior to more accurate recording devices aren't possible to compare.
See the law of large numbers. It is possible to get arbitrarily good estimates by combining sufficiently many fuzzy individual measurements. This is not an invention of some communist cabal of climate scientists, but was formalised by Bernoulli and Poisson in the 18th and 19th century. And it is, of course, used in every modern tracking radar system, wether to keep moving bodies apart or to bring them together.
That being said, even assuming arguendo that CO2 driven AGW is occuring, the solutions still have jack all to do with renewable energy. There are three possible solutions to the problem of large impact AGW, they are slaughter 90+% of the human race, try to chemically engineer the weather with various geoengineering attempts, or figure out a way to sequester carbon on a VERY large scale. Any other options are the fucking definition of whistling in the dark.
Thank's for your well-considered opinion. I'm sure both I and the world will give it the attention it deserves.
