Last year topped 2015 as the world’s warmest year in 137 years of record keeping, according to the 27th annual State of the Climate report.

The US report found that most indicators of climate change continued to follow trends of a warming world, and several, including land and ocean temperatures, sea level and greenhouse gas concentrations in the atmosphere broke records set just one year prior, said Wam, the Emirates official news agency.

Last year’s record heat resulted from the combined influence of long-term global warming and a strong El Nino early in the year.

This annual check-up for the planet, led by researchers from National Oceanic and Atmospheric Administration's National Centers for Environmental Information, is based on contributions from more than 450 scientists from nearly 60 countries. It provides a detailed update on global climate indicators, notable weather events and other data collected from land, water and space. It’s published as a special supplement to the Bulletin of the American Meteorological Society.

The report noted that greenhouse gases, global surface temperature, average sea surface temperature and global sea level were the highest on record.

Global upper-ocean heat content neared record high.

Arctic sea ice coverage was at or near record low, while tropical cyclones were above-average overall.
