It’s been so warm in the United States this year, especially in March, that national records weren't just broken, they were deep-fried.

Temperatures in the lower 48 states were 8.6 degrees above normal for March and 6 degrees higher than average for the first three months of the year, according to 50 by the National Oceanic and Atmospheric Administration. That goes far 51 the old records.

The extent of how 52 the year has been in the US has 53 some meteorologists(氣象學者) who have warned about global warming.

“Everybody has this uneasy feeling. This is not good,” said Jerry Meehl, a climate scientist who

54 in extreme weather at the National Center for Atmospheric Research in Boulder, Colo. “It’s a

55 pleasure. You’re out enjoying this 56 March weather, but you know it’s not a good thing.”

It’s not just March. “It’s been going on for several months,” said Jake Crouch, a climate scientist at NOAA’s National Climatic Data Center in Ashville, N.C.

Meteorologists say an unusual combination of several weather 57 , including La Nina, was the direct cause of the warm start to 2012. While individual events can’t be 58 on global warming, Crouch said this is like the extremes that are supposed to get more frequent because of 59 climate change from the burning of fossil fuels such as coal and oil.

Normally, March 60 42.5 degrees across the country. This year, the average was 51.1, which is closer to the average for April. Only one other time — in January 2006 — was the country as a whole that much 61 than normal for an entire month.

In March, 62 7,775 weather stations across the nation broke daily high temperature records and another 7,517 broke records for night-time 63 . Combined, that’s more high temperature records broken in one month than ever before, Crouch said.

“When you look at what’s happened in March this year, it’s beyond 64 ,” said University of Victoria climate scientist Andrew Weaver.
