[QUOTE="RLR, post: 126884, member: 486"] Bloomberg Visuals has a very cool graph for displaying average global temperature. [URL]http://www.bloomberg.com/graphics/2014-hottest-year-on-record/[/URL] Please don't think I'm endorsing (or denying) the accuracy of the data or drawing any conclusions from it. Really, I just think this is a cool way to construct a graph. I took 1 EAS class in college. I'm not great at math. And frankly, I never took too much interest in the topic because, with my skillset, I don't have much of a contribution to make. That said, I've always had some questions about global temperatures and don't really know where to look. Since this is a board of engineers, would you mind pointing me in the right direction? [LIST] [*]Are the sources for the temperature inputs from 1900 the same as the ones from 2014? Intuitively, it seems like the late 20th century would have more input sources and more sources in remote regions of the world.

How many points did Georgia Tech score against Cumberland in 1916?
