According to the new RSS MSU satellite data, September 2007 was the 7th coldest month among 81 months since January 2001. It has made it to the 9% of the coolest months of the 21st century so far. Their gadgets measure temperature at latitudes between -70.0 (S) and +82.5 (N) - about 94.5% of the surface if I compute well.
In the last month, the global temperature was just 0.12 Celsius degrees above the long-term average which means that it was 0.78 Celsius degrees cooler than the temperature in April 1998 when the anomaly was +0.9 Celsius degrees. The main reason is La Nina that is getting stronger and might continue to do so for a few months.
The Southern hemisphere was 0.015 Celsius degrees cooler (!) than the long-term average, fifth coldest month since January 2001. Antarctica has cooled down by roughly 1 Fahrenheit degree in the last 50 years.

By the way, in an interview with Dennis Prager, Prof Robert Giegenback who is a geologist at UPenn describes some climate issues from a geological perspective. Among other things, he argues that only during 5% of the last one billion of years, the Earth could support permanent ice on both poles. We're living in one of the coolest periods of the geological history.
