We gonna be burning and a-looting tonight;
(To survive, yeah!)
Burning and a-looting tonight;
(Save your baby lives)
Burning all pollution tonight;
(Pollution, yeah, yeah!)
Burning all illusion tonight

“In fact, years with La Niñas (which tend to cool global temperatures) are today warmer than El Niño years several decades ago. 2017 actually started out with a La Niña.” That sentence tells you all you need to know about Hotbox Earth today. Even with a supposed natural cooling trend earlier this year and “leveling off” of human greenhouse emissions temperatures continue to shoot up. Amid ominous reports that “greenhouse gases are rapidly changing and warming the atmosphere” and “arctic heat is becoming more common and persistent“, we find this unsurprising reality. Trump can’t trump ecocide I say. Burnin and lootin can’t continue to be the order of the day. We can’t keep obliterating forests, poisoning air, land and sea for our convenience and expect everything to be ok. Our illusory way of being can’t persist much longer. Sooner than we think, we’re gonna be gonners. Tick, tick, tick, tick, tick……”

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.
How monthly temperatures differ from the 1951-1980 average. So far, 2017 ranks behind only 2016 for the temperature for the first six months of the year.

“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.
The U.S. Southwest was another stand-out, with a heat wave that pushed temperatures so high they prevented some airplanes from taking off at Phoenix’s airport.
Every month of the year so far, including June, has ranked in the top three hottest for that month. Overall, the first six months of the year were 1.64°F (0.91°C) above the 20th century average of 56.3°F (13.5°C), according to NOAA. They were 0.29°F (0.16°C) behind the same period in 2016, which turned out to be hottest year on record, but ahead of 2015 by 0.09°F (0.05°C).
According to NASA, the first six months were 1.64°F above the 1951-1980 average.
The Paris Climate agreement, which President Trump has pledged to pull the U.S. out of, set a goal of limiting warming to under 2°C (3.6°F) above pre-industrial levels by the end of this century (and to aim for an even more ambitious 1.5°C (2.7°F)). To make the global temperatures more relevant to that measure, Climate Central re-analyzed the numbers by averaging together NASA and NOAA’s data and comparing them to the average for 1881-1910. June 2017 was 1.81°F (1.01°C) above that average, showing how little wiggle room is left to keep temperatures under that level.
While there were several spots that have seen record-warm years so far — including Mexico, parts of eastern Russia and China and western Europe — the heat is fairly broadly spread around the globe.
Five of the six continents had a top 10 warmest January-June, with South America hitting the No. 2 spot for that period (tying with 2010 and behind only 2015, according to NOAA.
Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, said that there was a 57 percent chance that 2017 would remain the second-hottest year on record through December, and even higher odds that it will end up in the top three. Sanchez-Lugo said that if the rest of the months of the year rank in the top two, 2017 will clinch the No. 2 spot; if they rank in the top three, it will fall to No. 3.
Wherever its final rank ends up, 2017 will almost certainly be hot enough to knock 1998 — the only remaining 20th century year among the top 10 warmest — down another spot, to No. 9 in NOAA’s rankings.
At the time, 1998’s heat was exceptional, and was fueled in part by a major El Niño, which tends to raise global temperatures. But as Earth’s temperature has steadily risen because of heat-trapping greenhouse gases, an El Niño isn’t necessary to reach those heights anymore.
In fact, years with La Niñas (which tend to cool global temperatures) are today warmer than El Niño years several decades ago. 2017 actually started out with a La Niña, albeit a weak one, but it is 0.38°F (0.21°C) ahead of 1998, Sanchez-Lugo, said.
If the streak of very warm years continues, “I wouldn’t be surprised if the next two to three years we would see ’98 drop out of the top 10 warmest years on record,” she said.
