(Bloomberg) -- Last month wasn’t just the hottest June onrecord — it continued the longest-ever streak of record-breakingmonths: 14.

It’s no longer a question of whether 2016 will be thehottest on record, but by how much.

The start of summer in the Northern Hemisphere gaveus the hottest June since 1880, according to datareleased Tuesday by the National Oceanic and Atmospheric Administration(NOAA). That follows the hottest May, April, March, February,January, December, November, October, September, August, and July.Before June 2016, June 2015 held the monthly record, as did May2015.

Last year’s massive El Niño warming pattern in the PacificOcean is over, but unprecedented heat remains across theplanet. The extremes of recent months are such that we’reonly halfway into 2016 and there’s already a greater than 99%likelihood that this year will be the hottest on record, accordingto Gavin Schmidt, who directs NASA’s Goddard Institutefor Space Studies. NASA and NOAA maintain independent records ofthe Earth’s temperatures, but they both agree that last month was ascorcher.

3rd year to set a new global heat record

This year is on track to be the third consecutive year to seta new global heat record — the first time that’s ever happened. Sofar, 15 of the hottest 16 years ever measured have come in the 21stcentury. Results from the world’s chief monitoringagencies vary slightly. The Japan MeteorologicalAgency said last month was tied with June 2015 for thatmonth’s record. Nevertheless, all agree that the extremes of2016 are unrivaled in the modern climate record.

The heat was experienced differently across the world, but feltto some degree almost everywhere. The dark red swaths in themap below show areas that set new records.

Some of this is still the result of El Niño, which releases heatfrom the Pacific that typically lingers for months after theunderlying conditions subside. Those conditions may soon shift to acooling La Niña, according to NOAA’s ClimatePrediction Center. The agency gives a roughly 60% chance of a La Niña pattern developing in the fall orwinter. That, however, doesn’t change Earth’s long-termtrajectory, or the fact that this summer’s heat is justgetting started.
