Surface temperatures are only one way to measure global warming, but it is a sort of standard and it is meaningful because surface temperatures have a lot to so with weather and such. Data for NASA's GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius using a base period of 1951-1980 can be found HERE. Climate Communicator ThingsBreak put a graph on the internet based on those data for November. Here's a copy of it:

Earth’s surface temperature in °C for each November since 1880 (compared to base period, 1951-1980). Stefan Rahmstorf, creator of the graphic, used the SSAtrend smoother described in Moore, J. C., et al., 2005. New Tools for Analyzing Time Series Relationships and Trends. Eos. 86, 226,232. The filter half-width is 15 years. The results are similar to using LOESS or LOWESS. The raw data are, of course, in blue.
