Halfway Through, 2017 Tracking As The Second-Hottest Year On Record
At the halfway point of the year, 2017 remains the second-hottest year to date — a surprise given the demise of the El Niño that helped boost temperatures to record levels last year. The continued near-record warmth is a marker of just how much global temperatures have risen thanks to the greenhouse gases accumulating in the atmosphere from fossil fuel use.
“Personally, I wasn't expecting it to be as warm as it has been,” Ahira Sanchez-Lugo, a National Oceanic and Atmospheric Administration climate scientist, said in an email. “After the decline of the strong El Niño I was expecting the values to drop a bit and rank among the top five warmest years. This year has been extremely remarkable.” The odds are good that 2017 will stay in second place through the end of the year, and it is even more likely that it will remain in at least the top three hottest years.
NOAA released its global temperature data for June on Tuesday, and ranked June as the third warmest in its records. The four-warmest Junes in its records have all happened in the past four years. (NASA, which released its June numbers on Friday, ranked June as the fourth hottest. The two agencies handle the data slightly differently, which can lead to small differences in their rankings, though they strongly agree on recent warming.)
The hotspots around the world for June included central Asia and western and central Europe. A searing heat wave in western Europe that helped fuel deadly wildfires in Portugal was made up to 10 times more likely because of Earth’s rising temperature, according to a recent study done in partnership with Climate Central.
