Global surface temperatures last year were tied with 2003 as the fourth-warmest on record, the National Oceanic and Atmospheric Administration reported Tuesday.
Nine of the 10 warmest years since records began in 1880 have occurred this century, according to NOAA.
The latest annual data arrives as the Obama administration is crafting new rules to curb carbon emissions from power plants and liberal Senate Democrats are trying to play political offense on climate change.
According to NOAA’s data, 2010 was the warmest year on record globally, followed by 2005 and 1998.
NASA, which provides rankings based on slightly different calculations, said Tuesday that 2013 was tied with 2009 and 2006 as the seventh-warmest on record (check out these slides for more on that).
The trend, a top NASA scientist said, is unmistakable.
“Long-term trends in surface temperatures are unusual and 2013 adds to the evidence for ongoing climate change,” said climatologist Gavin Schmidt of NASA’s Goddard Institute for Space Studies.
Global-warming skeptics have seized on the relative lack of surface warming since 1998 when battling federal regulations, and challenging the overwhelming majority of scientists who say human-induced climate change is a reality.
But NASA, echoing a 2013 report by the World Meteorological Organization, noted the decade-over-decade averages continue to show warming.
“Each successive year will not necessarily be warmer than the year before, but with the current level of greenhouse gas emissions, scientists expect each successive decade to be warmer than the previous,” NASA said in a statement alongside its latest data.

"It is with humility, determination, and boundless confidence in America’s promise that I accept your nomination for president," said Hillary Clinton in becoming the first woman to accept a nomination for president from a major party. Clinton gave a wide-ranging address, both criticizing Donald Trump and speaking of what she has done in the past and hopes to do in the future. "He's taken the Republican party a long way, from morning in America to midnight in America," Clinton said of Trump. However, most of her speech focused instead on the work she has done and the work she hopes to do as president. "I will be a president of Democrats, Republicans, and Independents. For the struggling, the striving, the successful," she said. "For those who vote for me and for those who don't. For all Americans together."
Supporters of Bernie Sanders promised to walk out, turn their backs, or disrupt Hillary Clinton's speech tonight, and they made good immediately, with an outburst almost as soon as Clinton began her speech. But her supporters, armed with a handy counter-chant cheat sheet distributed by the campaign, immediately began drowning them out with chants of "Hillary, Hillary!"
If a new poll is to be believed, Hillary Clinton has a big lead in the all-important swing state of Pennsylvania. A new Suffolk University survey shows her ahead of Donald Trump, 50%-41%. In a four-way race, she maintains her nine-point lead, 46%-37%. "Pennsylvania has voted Democratic in the past six presidential elections, going back to Bill Clinton’s first win in 1992. Yet it is a rust belt state that could be in play, as indicated by recent general-election polling showing a close race."
"President Barack Obama has chosen Jackson Park, a lakefront park that once hosted the world’s fair on the city’s South Side, for his $500 million presidential library, according to a person familiar with the matter."
Wednesday was the third night in a row that the Democratic convention enjoyed a ratings win over the Republican convention last week. Which might have prompted a fundraising email from Donald Trump exhorting supporters not to watch. "Unless you want to be lied to, belittled, and attacked for your beliefs, don't watch Hillary's DNC speech tonight," the email read. "Instead, help Donald Trump hold her accountable, call out her lies and fight back against her nasty attacks."
