But I have to wonder if climate science is too. I wonder what effect pure heat has on temperature :D. Anthropogenic heat generation has probably increased along similar, or perhaps even greater lines to that of carbon dioxide.
Using figures pulled from wikipedia, average global temperature is 14C, current is 14.4, so from what I've found today, temperature is 5.6% above normal, and has increased 11.2% since 1880. Atmospheric carbon dioxide has gone from 280ppm to 400, so 0.012% increase...
The greenhouse effect of carbon dioxide is far from linear too. The more there is, the less you get.
Please only reply if you can shed some light on my observations. I've already tried to work it out for myself, and no, I don't want to trust the "scientific consensus".
