emperature records were scorched last month, which will go down as the warmest March in history. According to the National Oceanic and Atmospheric Administration (NOAA), more than 15,000 temperature records were broken or tied in the U.S., continuing a year-long streak of hotter-than-average temperatures that many scientists are linking to global warming. "Everybody has this uneasy feeling," says scientist Jerry Meehl. "It's a guilty pleasure. You're out enjoying this nice March weather, but you know it's not a good thing." Here's how it all breaks down:
Temperature records that were set or tied across the U.S. in March, according to NOAA
Average March temperature, in degrees Fahrenheit, in the lower 48 states
Degrees by which that average temperature was hotter than the average for March in the 20th century
Degrees by which this March's average temperature beat the all-time March high, set in 1910. "Usually records are broken by just one- or two- tenths of a degree," says Seth Borenstein at the Associated Press.
Average U.S. temperature, in degrees Fahrenheit, for the first three months of 2012
Degrees by which this year's first-quarter average exceeded the warmest January-to-March average on record
States that had their warmest average March temperatures on record. But every state broke at least one daily temperature record during March, says Doyle Rice at USA Today.
This winter's rank on the list of warmest winters ever. The last year (April to April) has "been the hottest 12-month stretch on record," says NOAA climate scientist Jake Crouch.
