Highlights Concentrations of the major greenhouse gases, CO2 , CH4 , and N2 O, continued to increase despite the temporary reduction in emissions in 2020 related to measures taken in response to COVID-19. 2020 was one of the three warmest years on record. The past six years, including 2020, have been the six warmest years on record. Temperatures reached 38.0 C at Verkhoyansk, Russian Federation on 20 June, the highest recorded temperature anywhere north of the Arctic Circle. The trend in sea-level rise is accelerating. In addition, ocean heat storage and acidification are increasing, diminishing the ocean s capacity to moderate climate change. The Arctic minimum sea-ice extent in September 2020 was the second lowest on record. The sea-ice retreat in the Laptev Sea was the earliest observed in the satellite era. The Antarctic mass loss trend accelerated around 2005, and currently, Antarctica loses approximately 175 to 225 Gt of ice per year. The 2020 North Atlantic hurricane season was exceptionally active. Hurricanes, extreme heatwaves, severe droughts and wildfires led to tens of billions of US dollars in economic losses and many deaths. Some 9.8 million displacements, largely due to hydrometeorological hazards and disasters, were recorded during the first half of 2020. Disruptions to the agriculture sector by COVID-19 exacerbated weather impacts along the entire food supply chain, elevating levels of food insecurity.
