Hadley December temperature anomaly

Hadley says...that December's 2008 temperature anomaly was +0.308°C

(Q: why does Hadley report temperature anomalies to 3-significant digits but NASA GISS only to two?)

So, for the 3rd month in a row, surface temperatures are warmer than the previous year's -- and for five out of six of past months. But overall Hadley has 2008 cooler than 2007, +0.327°C to +0.399°C, and 2008 as the coolest year since 2000.

Meanwhile, as RealClimate wrote today, the world's continue to melt. And this decade's temperatures are far ahead of last decade's. How exactly do you want to slice this data?
