130 Years of Earth Surface Temperatures
http://apod.nasa.gov/apod/ap130731.html
Explanation: How has the surface temperature of Earth been changing?
To help find out, Earth scientists collected temperature records from
over 1000 weather stations around the globe since 1880, and combined
them with modern satellite data. The above movie dramatizes the
result showing 130 years of planet-wide temperature changes relative
to the local average temperatures in the mid-1900s. In the above
global maps, red means warmer and blue means colder. On average, the
display demonstrates that the temperature on Earth has increased by
nearly one degree Celsius over the past 130 years, and many of the
warmest years on record have occurred only recently. Global climate
change is of more than passing interest -- it is linked to global
weather severity and coastal sea water levels.
