Today the World Meteorological Organization (WMO) released a provisional statement on the status of global climate in 2011. At this point it seems appropriate to point out that we have been here before and heard the same things stated over and over again.
Based on data collected from the WMO around the world, they are concluding that despite the fact that 2011 was a La Niña year, it is currently tied as the 10th warmest year on record globally. As you can see on the graph above during La Niña events global temperatures typically cool. The data also shows that the average temperatures seen during La Niña events is trending upwards as well meaning the cool years are getting a lot less cool.
