Comparing 20 Years of Global Temperature Trends [1080p]

All of the Top 10 Warmest Average Global Temperatures recorded since 1880 have occurred in the last fifteen years. The hottest year on record, 2005, is being matched by the temperatures recorded so far in 2010. Analysis by the National Climatic Data Center reveals that May of 2010 was the warmest global average for that month on record, and is also the warmest year-to-date from January to May. This animated graph plots the year-to-date average global temperature for each year since 1990. Year-to-date refers to a running average of the entire year, not discrete averages of each month.
