2017 Was One Of The Hottest Years On Record

"NOAA has released the latest State of the Climate report, its annual checkup on our planet."

"So, how did Earth fare in 2017?"

"Greenhouse gases in the atmosphere: highest concentrations ever. Global surface temperature: near-record high. Sea surface temperature: near-record high. Global sea level: highest on record."

"Warm global temperatures have been a strong trend in recent years: the four warmest years on record all occurred since 2014, and last year was among them. In fact, 2017 was the warmest non-El Niño year ever recorded."

"The past three years were 'substantially warmer than the previous — kind of establishing a new neighborhood in terms of global temperature,' said Deke Arndt, a climatologist at NOAA and the lead editor of the report. 'And 2017 reinforced that.'"
