And 30 years is about 1/3 of the time between 1900 and 2000. Your point?
Temperatures are simply returning to the norm they were at 1000 years ago before the Little Ice Age. One study of the Milankovitch cycles by Berger and Loutre predicts the current warm climate may last another 50,000 years.

Point one: I make mistakes. Point two: The trend is 0.2 C per decade, so 0.2 C in 10 years is 1/3 of the total global temperature increase in the 20th century. Or, to put it another way, 0.6 C in the past 30 years is approximately the same increase in global temperature observed in the 20th century.
