Did World Temperatures Drop Last Year?

And —by enough to virtually offset the entire “unprecedented warming” of the last century?

We certainly haven't read this in the Dom Post recently.

According to this article from the Center For Global Food Issues

Britain’s Hadley Centre, NASA, and the University of Alabama/Huntsville say the temperature drop since January of 2007 was measured between 0.59 and 0.75 degree C. This includes an unusually cold winter in the Southern Hemisphere, and the harshest Chinese winter in a century. Part is due to a regional cooling in the Pacific called La Nina which appears every 4-5 years, but the strength and global scope of this cooling has been startling.

It certainly was a cold winter in New Zealand last year. Was this due to greenhouse gas emissions? Or are some other factors at play?
