2010 has also surpassed 1998 for the most “warmest months” in any calendar year, the center stated.

“Each of the 10 warmest average global temperatures recorded since 1880 have occurred in the last fifteen years,” it added. “The warmest year-to-date on record, through June, was 1998, and 2010 is warmer so far (note: although 1998 was the warmest year through June, a late-year warm surge in 2005 made that year the warmest total year).”
