Government scientists say Earth sizzled to a third straight heat record last year.
They mostly blame man-made global warming with help from a natural El Niño which has since dispelled.
The figures announced Wednesday come from NASA and the National Oceanic and Atmospheric Administration, which measure global temperatures in slightly different ways. They said last year passed 2015 as the hottest year on record.
NOAA calculated that the average global temperature last year was 58.69 degrees (14.84 degrees Celsius) — beating the previous year by .07 degrees (.04 Celsius).
