Planetary warming continued in 2016, setting a new record of about 1.1 degrees Centigrade above the preindustrial period, according to the World Meteorological Organization (WMO) Statement on the State of the Global Climate in 2016. Drought conditions predominated across much of the globe, aggravated by the El Niño phenomenon In the Statement, WMO also noted that the extent of global sea ice fell to a minimum of 4.14 million km2 in 2016, the second lowest extent on record. Atmospheric carbon dioxide levels also reached a record high of 400 parts per million that year. Mitigating climate change and its impacts will require building on the momentum achieved by the Paris Agreement on Climate Change, which entered into force on 4 November 2016. Stronger efforts are needed to build resilience and limit climate-related hazards and natural disasters.

The year 2017 was one of the three warmest on record and was 1.1 degrees Celsius above the pre-industrial period. An analysis by the World Meteorological Organization shows that the five-year average global temperature from 2013 to 2017 was also the highest on record. The world continues to experience rising sea levels, extreme weather conditions (the North Atlantic hurricane season was the costliest ever recorded) and increasing concentrations of greenhouse gases. This calls for urgent and accelerated action by countries as they implement their commitments to the Paris Agreement on Climate Change.
