0.2 C in 30 years is 1/3 of the total global temperature increase (approximately) from 1900-2000.
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.
....and that makes perfect sense. If the global temperature rose 0.6 C in 100 years, then it would rise 0.2 C in 33 1/3 years. So it's increased that much in 30 years instead of 33 1/3 years, I don't see that as significant.
