WASHINGTON — Earth is on pace to tie or even break the mark for the hottest year on record, federal meteorologists say.

That’s because global heat records have kept falling in 2014, with September the latest example.

The National Oceanic and Atmospheric Administration announced Monday that last month the globe averaged 60.3 degrees Fahrenheit. That was the hottest September in 135 years of record keeping.

It was the fourth monthly record set this year, along with May, June and August.

NASA, which measures temperatures slightly differently, had already determined that September was record-warm.

The first nine months of 2014 have a global average temperature of 58.72 degrees, tying with 1998 for the warmest first nine months on record, according to NOAA’s National Climatic Data Center in Asheville, N.C.

“It’s pretty likely” that 2014 will break the record for hottest year, said NOAA climate scientist Jessica Blunden.

If 2014 breaks the record for hottest year, that also should sound familiar: 1995, 1997, 1998, 2005 and 2010 all broke NOAA records for the hottest years since records started being kept in 1880.

“This is one of many indicators that climate change has not stopped and that it continues to be one of the most important issues facing humanity,” said University of Illinois climate scientist Donald Wuebbles.
