What if all of the thermometers had bad data back then? Or not the thermometers, but the people reporting the temps weren't the most accurate? And we weren't even measuring ocean temps back then, just temps at stations, which were probably in cities. We had no idea if there was an El Nino or La Nina in 1885. We can only guess based off of observations.
But, let's assume you're right. Let's assume that the average temperature, globally has increased by 2C since 1880 and that we're hotter than we've been in a long time. Well, what were the conditions like thousands of years ago? Seems to me that human beings survived this pretty well.
I don't disagree that that earth is warming, I disagree with the hysteria surrounding it. "We only have 10 years to save civilization before we go extinct!" C'mon.
