0.2 C in 30 years is 1/3 of the total global temperature increase (approximately) from 1900-2000.

....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.

The trend is currently +0.2 C per decade: 2.0 C in 100 years.
