America set an off-the-charts heat record in 2012.
A brutal combination of a widespread drought and a mostly absent winter pushed the average annual U.S. temperature last year up to 55.32 degrees Fahrenheit, the government announced Tuesday. That’s a full degree warmer than the old record set in 1998.
Breaking temperature records by an entire degree is unprecedented, scientists say. Normally, records are broken by a tenth of a degree or so.
The National Climatic Data Center’s figures for the entire world won’t come out until next week, but through the first 11 months of 2012, the world was on pace to have its eighth warmest year on record.
Scientists say the U.S. heat is part global warming in action and natural weather variations. The drought that struck almost two-thirds of the nation and a La Nina weather event helped push temperatures higher, along with climate change from man-made greenhouse gas emissions, said Katharine Hayhoe, director of the Climate Science Center at Texas Tech University. She said temperature increases are happening faster than scientists predicted.
“These records do not occur like this in an unchanging climate,” said Kevin Trenberth, head of climate analysis at the National Center for Atmospheric Research in Boulder, Colo. “And they are costing many billions of dollars.”
Last year was 3.2 degrees warmer than the average for the entire 20th century. Last July was the also the hottest month on record.
Nineteen states set yearly heat records in 2012. Alaska, however, was cooler than average.
U.S. temperature records go back to 1895 and the yearly average is based on reports from more than 1,200 weather stations across the Lower 48 states.
According to the National Oceanic and Atmospheric Administration, the U.S. last year also had the second most weather extremes on record, behind 1998. There were 11 different disasters that caused more than $1 billion in damage, including Superstorm Sandy and the drought, NOAA said.
The drought was the worst since the 1950s and slightly behind the dust bowl of the 1930s, meteorologists said. During a drought, the ground is so dry that there’s not enough moisture in the soil to evaporate into the atmosphere to cause rainfall. And that means hotter, drier air.
The last time the country had a record cold month was December 1983.
“A picture is emerging of a world with more extreme heat,” said Andrew Dessler, a Texas A&M University climate scientist. “Not every year will be hot, but when heat waves do occur, the heat will be more extreme. People need to begin to prepare for that future.”

Magistrate rejects Nagin’s bid for report
A federal magistrate refused Tuesday to order prosecutors to provide former New Orleans Mayor Ray Nagin with a copy of a sealed report on alleged prosecutorial misconduct before his trial on bribery charges.

High court wary of campaign contribution limits
The Supreme Court appeared ready Tuesday to free big individual donors to give more money to political candidates in the court’s first major campaign finance case since the justices took the lid off of independent spending in 2010.
The court’s conservative justices, who formed the majority in 2010’s Citizens United case, voiced varying degrees of skepticism about the limits on what individuals may give candidates, political parties and political action committees in a two-year federal election cycle.
Texas Guard refuses to process same-sex benefits
The Texas National Guard refused to process requests from same-sex couples for benefits on Tuesday despite a Pentagon directive to do so, while Mississippi won’t issue applications from state-owned offices. Both states cited their respective bans on gay marriage.
Tuesday was the first working day that gays in the military could apply for benefits after the Pentagon announced it would recognize same-sex marriages. The Department of Defense had announced that it would recognize same-sex marriages performed in states where they are legal following the U.S. Supreme Court decision that threw out parts of the Defense of Marriage Act.
Obama to seek congressional OK for Syria action
Short on support at home and allies abroad, President Barack Obama unexpectedly stepped back from a missile attack against Syria on Saturday and instead asked Congress to support a strike punishing Bashar Assad’s regime for the alleged use of chemical weapons.
With Navy ships on standby in the Mediterranean Sea ready to launch their cruise missiles, Obama said he had decided the United States should take military action and that he believes that as commander in chief, he has “the authority to carry out this military action without specific congressional authorization.”
At the same time, he said, “I know that the country will be stronger if we take this course and our actions will be even more effective.” His remarks were televised live in the United States as well as on Syrian state television with translation.
