La Niña ends; neutral conditions return over equatorial Pacific Ocean

According to NOAA scientists, the globally-averaged temperature for April marked the fifth warmest April since record keeping began in 1880. April 2012 also marked the largest departure from the 20th century average temperature in more than a year.

La Niña, typically associated with cooler global temperatures, dissipated and transitioned to neutral conditions during April as sea surface temperatures continued to warm across the equatorial Pacific Ocean. According to NOAA's Climate Prediction Center, neutral conditions are expected to continue through the Northern Hemisphere's summer.
