Oh, right. Well, it's all right then.
Of course, if you're going to look at past warming events you might find this interesting: "There have been three major greenhouse phases in the time period we analyzed and the peaks in temperature of each coincide with mass extinctions," http://www.scientificamerican.com/article.cfm?id=mass-extinctions-tied-to-past-climate-changes
"Global temperature rose five degrees Celsius 56 million years ago in response to a massive injection of greenhouse gases into the atmosphere.
That intense gas release was only 10 percent of the rate at which heat-trapping greenhouse gases are building up in the atmosphere today."
