However
This is great. They assume burning of fossil fuels is the primary cause of global warming, but:
"though there was a "leveling off" between the 1940s and 1970s"
Isn't that the time frame of things like the V8 cars/trucks that got 8mpg, nuclear bomb testing, and coal-based power plants burning at full steam with next to no regard for emission filters? Granted they have most likely built more coal plants since then, but all have been tightly mandated on emissions....Perhaps the nuclear blasts were saving us! (not likely, but hey, why not jump to conclusions?)
Also, wasn't it NASA that calculates "average global temperature" by averaging select regions of the world, while neglecting regions of africa, Atlantic, Indian, and Pacific oceans, and large regions of the Antartic? Most of which are shown by satellite-based temperature-monitoring stations to have "normal" or "below average" temperatures....
Perhaps NASA just borrows data from our Climategate friends. Any Scientist's collected data has to be legit, right?
Don't get me wrong here. I full well believe something we are doing as a species is causing adverse effects on our environment. Just what that is? I'm probably as in-the-dark as these scientists, except I'm not publicising my stabs-in-the-dark.
Paris, perhaps the average temperature was raised by all the people she makes hot and bothered....
