NOAA released their global climate summary for March 2015 today. It shows that March was the warmest on record for the Earth as a whole since historical records began in 1880. The first quarter, January through March, was also the warmest on record. The eastern US was one of the few places that was near or below normal (see map below).
In addition, the Arctic set a record for the lowest amount of sea ice in March since satellite records began in 1979, while sea ice in Antarctica was the second highest amount in March for the same period.
