2007 warmest year on record? Coldest in this century

See the whole post from Lubos Motl here.

Excerpts:

In January 2007, we were informed that 2007 was either likely or certain to surpass 1998 and become the world's warmest year on record by most media...One month ago, we noticed that November 2007 was the coldest month since January 2000. Well, the RSS MSU satellite data show that December was even cooler. The December anomaly was -0.046 °C, compared to -0.014 °C in November. That means that December 2007 was also cooler than the average December from 1979...The RSS MSU linear trend extracted from the 1998-2007 interval is -0.48 °C per century of cooling! Numerically, it's the same trend that we assign to the 20th century but with the opposite sign!
