’17’s first half sec­ond-warmest logged

Northwest Arkansas Democrat-Gazette - - NATIONAL -

WASH­ING­TON — The first half of 2017 was the sec­ond warmest on record for Earth, only be­hind last year.

On Tues­day, the Na­tional Oceanic and At­mo­spheric Ad­min­is­tra­tion an­nounced that Earth’s av­er­age tem­per­a­ture from Jan­uary to June was 57.9 de­grees. That’s 1.6 de­grees warmer than the 20th-cen­tury av­er­age.

Nat­u­ral El Nino weather con­di­tions can cause spikes global tem­per­a­tures. The term El Nino refers to a large-scale flow of warm sur­face water across the cen­tral and east-cen­tral equa­to­rial Pa­cific that can dis­rupt weather pat­terns.

Ad­min­is­tra­tion cli­mate sci­en­tist Ahira Sanchez-Lugo said it is re­mark­able that 2017, which hasn’t seen an El Nino pat­tern, so far beats all but the su­per El Nino year of 2016.

She said that’s an in­di­ca­tion that the world is chang­ing into an ever-warm­ing cli­mate.
