We aren't spouting off doomsday scenarios here. The majority of scientists who are studying climate are saying that humans have had an impact on climate, but they don't go saying it's the end of the world either. That's what journalists are for.

What alarikf is saying, and what I'm saying, is: the data supports the model that humans have had an impact on the rise of temperatures in the world. You cannot deny the entire hypothesis that human action has increased global temperatures based solely on a few bits of data that does not fit the model. To deny the hypothesis, you must show that something else accounts for the data. You may introduce doubts about how much data is explained by the model, but by scientific reasoning, you cannot throw it out entirely unless you replace it with a better model OR show that the data does not fit the model after all.

So, sorry, but I'm not seeing why you have an objection. We have very accurate data from late 1800's to present for temperature (to within fractions of a degree). We have fairly accurate data going back several centuries (to within a few degrees when averaged out). We also have data that goes back for millenia from the arctic and antarctic ice shelves. It shows strong correlations between percentage of atmospheric carbon dioxide and temperature. The western Industrial Revolution has been steadily pumping more carbon dioxide into the atmosphere, and the temperature has steadily been rising. Model fits. Where is the problem here?
