Analysis by Janet Larsen and Sara Rasmussen*

WASHINGTON, Feb 1, 2012 (IPS) - The global average temperature in 2011 was 14.52 degrees Celsius (58.14 degrees Fahrenheit). According to NASA scientists, this was the ninth warmest year in 132 years of recordkeeping, despite the cooling influence of the La Niña atmospheric and oceanic circulation pattern and relatively low solar irradiance.

Since the 1970s, each subsequent decade has gotten hotter - and nine of the 10 hottest years on record have occurred in the 21st century.
