WASHINGTON (AP) — It has been so warm in the United States this year, especially in March, that national records were not just broken, they were deep-fried.
[B]Temperatures in the lower 48 states were 8.6 degrees (4.8 degrees Celsius) above normal for March and 6 degrees (3.3 degrees Celsius) higher than average for the first three months of the year, according to calculations by the National Oceanic and Atmospheric Administration. That far exceeds the old records.[/B]
The magnitude of how unusual the year has been in the U.S. has alarmed some meteorologists who have warned about global warming. One climate scientist said it is the weather equivalent of a baseball player on steroids, with old records obliterated.
"Everybody has this uneasy feeling. This is weird. This is not good," said Jerry Meehl, a climate scientist who specializes in extreme weather at the National Center for Atmospheric Research in Boulder, Colo. "It's a guilty pleasure. You're out enjoying this nice March weather, but you know it's not a good thing."
It's not just March.
"It's been ongoing for several months," said Jake Crouch, a climate scientist at NOAA's National Climatic Data Center in Asheville, N.C.
Meteorologists say an unusual confluence of several weather patterns, including La Nina, was the direct cause of the warm start to 2012. While individual events cannot be blamed on global warming, Crouch said this is like the extremes that are supposed to get more frequent because of man-made climate change. Greenhouse gases come from the burning of fossil fuels such as coal and oil.
It is important to note that this unusual winter heat is mostly a North America phenomenon. Much of the rest of the Northern Hemisphere has been cold, said NOAA meteorologist Martin Hoerling.
[B]The first quarter of 2012 broke the January-March record by 1.4 degrees (0.8 degrees Celsius). Usually records are broken by just one- or two-tenths of a degree. [U]U.S. temperature records date from 1895[/U].[/B]
[B]The atypical heat goes back even further. The U.S. winter of 2010-2011 was slightly cooler than normal and one of the snowiest in recent years, but after that things started heating up. The summer of 2011 was the second warmest summer on record.
The winter that just ended, which in some places was called the year without winter, was the fourth warmest on record. Since last April, it has been the hottest 12-month stretch on record, Crouch said.[/B]
But the month where the warmth turned especially weird in the United States was March.
Normally, March averages 42.5 degrees (5.8 degrees Celsius) across the country. This year, the average was 51.1 (10.6 degrees Celsius), which is closer to the average for April. Only one other time, in January 2006, was the country as a whole that much hotter than normal for an entire month.
The "icebox of America," International Falls, Minn., saw temperatures in the 70s for five days in March, and there were only three days of below zero temperatures all month.
In March, at least 7,775 weather stations across the nation broke daily high temperature records, and another 7,517 broke records for night-time heat. Combined, that is 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 unbelievable," said University of Victoria climate scientist Andrew Weaver.
NOAA climate scientist Gabriel Vecchi compared the increase in weather extremes to baseball players on steroids: You can't say an individual homer is because of steroids, but they are hit more often and the long-held records for home runs fall.
They seem to be falling far more often because of global warming, said NASA top climate scientist James Hansen. In a paper he submitted to the journal Proceedings of the National Academy of Sciences and posted on a physics research archive, Hansen shows that heat extremes aren't just increasing but happening far more often than scientists thought.
What used to be a 1-in-400 hot temperature record is now a 1 in 10 occurrence, essentially 40 times more likely, said Hansen. The warmth in March is an ideal illustration of this, said Hansen, who also has become an activist in fighting fossil fuels.
Weaver, who reviewed the Hansen paper and called it "one of the most stunning examples of evidence of global warming."

[QUOTE]So Very, Very Cold In Alaska For January with Impressive Records
Feb 1, 2012; 1:33 PM ET
The month of January has gone down as one of the coldest on record for portions of Alaska, especially the central and western sections. If you live in the states and wonder where all the cold air has been, this is where some of it has been residing.
Some of the coldest low temperatures of the month occurred in the last few days.
Fort Greely: minus 50 on Jan. 29
Eagle: minus 58 on Jan. 29
Circle Hot Springs: minus 58 on Jan. 29
Kandik River: minus 64 on Jan. 29
Chicken: minus 59 on Jan. 29
Fort Yukon: minus 66 on Jan. 31
Many places had either the coldest January on record, or one of the coldest, and some places set the coldest month ever on record.
-Fairbanks: January 2012 was the fifth coldest on record with an average temperature of minus 26.9. Coldest January since 1971. Coldest low was minus 51 on Jan. 29.
-Nome: Coldest January on record with an average temperature of -16.6, records go back to 1909
-Kotzebue: Second coldest January on record and the coldest since 1934, records date back to 1929.
-Galena: January was the coldest month EVER on record with an average temperature of minus 32.6 degrees. Lowest temperature was minus 65 with four consecutive days of minus 60 degrees or lower low temperatures. Records go back to 1942.
-McGrath: Coldest month every on record with an average temperature of minus 28.5, records date back to 1939.
-Bettles: Coldest month ever on record with average temperature of minus 35.6, records dating back to 1951.
-Tanana: January 2012 is the coldest January in over 100 years, only January 1906 was colder.
-Anchorage: Averaged 14.6 degrees below normal for the month with Wasilla averaging 15.7 degrees below normal.
This weekend I heard tell of there being a record of palm trees found in the Arctic, during something called the Tertiary Period. Some really fascinating stuff about proto-mammals and methane gases being trapped and slowly escaping in places like, well, the southern US.
I suppose one could say that what (may be) happening now has happened before.
