NOAA Makes It Official: 2015 Has Been Really Hot

Federal data shows that the world sweated through the warmest August on record—and the warmest summer, too.

The world ex­per­i­enced the warmest Au­gust on re­cord, and the plan­et is still on pace for the hot­test year in meas­ure­ments that date back to the late 1800s, ac­cord­ing to new fed­er­al data re­leased Thursday.

Just in from the Na­tion­al Ocean­ic and At­mo­spher­ic Ad­min­is­tra­tion: The glob­al av­er­age tem­per­at­ure over land and ocean sur­faces com­bined was 1.58 de­grees Fahren­heit warm­er than the 20th-cen­tury av­er­age, and it beat the pre­vi­ous pre­vi­ous Au­gust re­cord set in 2014 by 0.16 de­grees.

Au­gust wasn’t the only steamy month. Ac­cord­ing to NOAA, it was the warmest sum­mer, too, as the June-to-Au­gust stretch beat out last year’s pre­vi­ous re­cord.

The new find­ings are con­sist­ent with oth­er data sets. Mash­able ’s An­drew Freed­man re­por­ted Wed­nes­day that both NASA and the Ja­pan Met­eor­o­lo­gic­al Agency data show the hot­test sum­mer on re­cord.

The same NOAA re­port out Thursday shows that 2015 has been the hot­test year on re­cord thus far, best­ing the pre­vi­ous Janu­ary-to-Au­gust re­cord set in 2010. Glob­al tem­per­at­ures to date this year have been 1.51 de­grees above the 20th-cen­tury av­er­age, the agency said.

All in all, 2015 looks very likely break the re­cord as the hot­test year.

Sev­er­al NOAA ex­perts ex­plored the odds in a blog post Thursday.

“[T]he his­tor­ic­al data sug­gest it would take a re­mark­able and ab­rupt re­versal in the NOAA­G­lob­al­Temp time series over the re­mainder of the year to upend 2015’s drive to­ward re­cord-break­ing status. In oth­er words, it ap­pears ex­tremely un­likely that 2015 will lose its com­mand­ing lead,” they write.

One ma­jor en­vir­on­ment­al group quickly seized on the new data to try and boost mo­mentum for reach­ing a mean­ing­ful glob­al-warm­ing ac­cord at the high-stakes in­ter­na­tion­al cli­mate talks in Par­is later this year.

“It’s up to world lead­ers: 2015 could go down as merely an­oth­er re­cord-break­ing year of warm­ing and its costly con­sequences, or it could also be the pivotal year of pro­gress in the fight against cli­mate change,” said Lou Le­onard, vice pres­id­ent for cli­mate change at the World Wild­life Fund.
