There is a lot not clear about the weather. In the US Northeast, it is clearly quite warm and almost hot. The average global temperature for March 2012 made it the coolest March since 1999, yet the 16th warmest since record keeping began in 1880. Arctic sea ice extent during the month was below average but was the largest extent since 2008 and one of the largest March extents of the past decade. Additionally, La Niña conditions continued to weaken during March as temperatures across the equatorial Pacific Ocean warmed during the last two months. According to NOAA’s Climate Prediction Center, La Niña is expected to dissipate by the end of April 2012.
