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.
