»Das vergangene Jahrzehnt war das wärmste seit Beginn der Aufzeichnungen«

Klimareport der Weltorganisation für Meteorologie, 11.3.2020 (engl. Originalfassung)

The year 2019 ended with a global average temperature of 1.1 °C above estimated pre-industrial averages, second only to the record set in 2016. Without the role of El Niño in the warming increase observed in 2016, 2019 would have been a record year.The year 2019 is likely to have been the second warmest in instrumental records. The past five years are the five warmest on record, and the past decade, 2010–2019, is also the warmest on record.

The results of this report demonstrate that climate change is already very visible in various ways. More ambitious climate mitigation efforts are needed to keep the warming below 2 °C by the end of the century.We are currently way off track to meeting either the 1.5 °C or 2 °C targets that the Paris Agreement calls for.

Furthermore, in 2019, heatwaves, combined with long periods of drought, were linked to wildfires of unprecedented size. This was the case in Australia, where millions of hectares were set ablaze, and in Siberia and other Arctic regions hit by wildfires of record has been weather-related damage, such as the effects of multi-annual droughts on the internal and cross-border migration of populations, greater exposure of the world population to health hazards due to heat and pollution, and the reduction of economic growth, especially in developing economies, due to rising temperatures and weather extremes.
