Baseline Temperature for the last 128 years
You can find the video here. It is a video of the average change in temperature from a baseline (the baseline is the average temperature from 1951 to 1980) from the years 1884 to 2012.

Temperatures are, on average, lower during the first half of the video and warmer in the second half, in particular during the last 10 years. Part of this is an artifact of taking the average from the years 1951 to 1980, but the Earth's average temperature should be similar to that average over the long-term with small-scale fluctuations in the short-term.

What you see though, is that temperatures were much warmer for a period of decades from 1884 to 1910, are around 0 for the years from which the average is taken, and then a marked increase in the latter decades. The overall warming is quite astounding in visual form.

Equally as astounding is watching areas off of the southwest coast of Argentina (near Antarctica) go from warmer than average, to colder than average.
