The last eight years have been the eight warmest on record as the growing concentration of heat-trapping gases in the atmosphere pushes global temperatures toward a dangerous tipping point, a new report shows.
An analysis by the European Union’s Copernicus Climate Change Service published on Tuesday said that 2022 was the fifth-warmest year for the planet since records began. It also reported Europe recorded its warmest summer last year and its second warmest year overall, exceeded only by 2020.
Copernicus described 2022 as “a year of climate extremes” that brought record-breaking heatwaves in Europe, deadly floods in Pakistan, extreme widespread flooding in Australia, and that saw the Antarctic Sea reach its lowest minimum extent on record.
The report said that annual average temperature reached 1.2 degrees Celsius above pre-industrial levels, marking the eighth year in a row of temperatures at least 1 degree above the 1850 to 1900 reference period.
Under the 2015 Paris Agreement, most countries agreed to limit warming to well below 2 degrees above pre-industrial levels, but preferably to 1.5 degrees.
Before humans started to burn large quantities of fossil fuels, the concentration of CO2 in the atmosphere was around 280 parts per million. According to Copernicus, it hit an annual average of 417 parts per million in 2022, an increase of 2.1 parts per million compared to 2021. Records show the concentration of carbon in the atmosphere has not been this high in around 2 million years, Copernicus added.
