WMO Statement on the State of the Global Climate 2019

A new report was released by the World Meterological Organization on the State of the Global Climate 2019

Key findings of the reporte include:

- The ocean absorbs around 90% of the heat that is trapped in the Earth system by rising concentrations of greenhouse gases. Ocean heat content, which is a measure of this heat accumulation, reached recordhigh levels again in 2019.

- The global mean temperature for 2019 was 1.1±0.1 °C above pre-industrial levels. 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. Since the 1980s, each successive decade has been warmer than any preceding one since 1850. 

-Global atmospheric mole fractions of greenhouse gases reached record levels in 2018 with carbon dioxide (CO2) at 407.8±0.1 parts per million (ppm), methane (CH4) at 1869±2 parts per billion (ppb) and nitrous oxide (N2O) at  31.1±0.1 ppb. These values constitute, respectively,147%, 259% and 123% of pre-industrial levels. Early indications show that the rise in all three – CO2, CH4 and N2O – continued in 2019.

- The year 2019 saw low sea-ice extent in both the Arctic and the Antarctic. The daily Arctic sea-ice extent minimum in September 2019 was the second lowest in the satellite record. In Antarctica, variability in recent years has been high  with the long-term increase offset by a large drop in extent in late 2016. Extents have since remained low, and 2019 saw record-low extents in some months.
