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 was obvious he wasn't prepared." “He only mentioned her email scandal once." "I think he took things a little too personal and missed a lot of opportunities to make very good debate points." That's just a smattering of the reactions of some elected Republicans to Donald Trump's debate performance.
The conventional wisdom is already emerging that Donald Trump opened last night's debate well, but that he faded badly down the stretch. And most viewers apparently witnessed it. "The early Nielsen data confirms that viewership stayed high the entire time. Contrary to some speculation, there was not a big drop-off after the first hour of the 98-minute debate." Final data is still being tallied, but "Monday's face-off may well have been the most-watched debate in American history. CNN and other cable news channels saw big increases over past election years. So did some of the broadcast networks."
As Congress continues to bicker on riders to a continuing resolution, federal agencies have started working with the Office of Management and Budget to prepare for a government shutdown, which will occur if no continuing resolution is passed by 11:59 p.m. on Friday night. The OMB held a call with agencies on Sept. 23, one that is required one week before a possible shutdown. The government last shut down for 16 days in 2013, and multiple shutdowns have been narrowly avoided since then. It is expected that Congress will reach a deal before the clock strikes midnight, but until it does, preparations will continue.
