A new State of the Climate report confirmed that 2017 was one of the three warmest years in records dating to the mid-1800s.
Last year was one of the warmest years on record despite the lack of a short-term warming El Niño influence. The report found that the major indicators of climate change continued to reflect trends consistent with a warming planet. Several markers such as greenhouse gas concentrations in the atmosphere and sea level broke records set just one year prior.
