This past March was unsually warm in case you didn’t notice. From Sciencenews.org:

People may argue about why Earth is warming, how long its fever will last and whether any of this warrants immediate corrective action. But whether Earth is warming is no longer open to debate. The National Oceanic and Atmospheric Administration has just published domestic examples to reinforce what Americans witnessed last month — either on TV or in their own backyards.

Let’s start with the heat: March 2012 temperatures averaged 10. 6° Celsius (51° Fahrenheit) — or 5.5 °C warmer than the 20th century average across the contiguous United States. Throughout the more than 115 years that national U.S. weather data have been compiled, only one other month (January 2006) surpassed this past March in its departure from the average.

In all, U.S. weather stations logged almost 15,300 all-time highs, last month, roughly half of them for nighttime temps. “There were 21 instances of the nighttime temperatures being as warm, or warmer, than the existing record daytime temperature for a given date,” NOAA’s new analysis finds. Only Alaska bucked the trend; its temperatures were the tenth coolest for March.
