WMO - Past Eight Years Are The Eight Warmest On Record; Record GHG Emissions Growth Rate
The past eight years were the eight hottest ever recorded, a new UN report has found, indicating the world is now deep into the climate crisis. The internationally agreed 1.5C limit for global heating is now barely within reach, it said.
The report, by the UNs World Meteorological Organization (WMO), sets out how record high greenhouse gases in the atmosphere are driving sea level and ice melting to new highs and supercharging extreme weather from Pakistan to Puerto Rico.
The stark assessment was published on the opening day of the UNs Cop27 climate summit in Egypt and as the UN secretary-general warned that our planet is on course to reach tipping points that will make climate chaos irreversible. The WMO estimates that the global average temperature in 2022 will be about 1.15C above the pre-industrial average (1850-1900), meaning every year since 2016 has been one of the warmest on record.
EDIT
The WMO report said:
Carbon dioxide, methane and nitrous oxide are at record levels in the atmosphere as emissions continue. The annual increase in methane, a potent greenhouse gas, was the highest on record.
The sea level is now rising twice as fast as 30 years ago and the oceans are hotter than ever.
Records for glacier melting in the Alps were shattered in 2022, with an average of 13ft (4 metres) in height lost.
Rain not snow was recorded on the 3,200m-high summit of the Greenland ice sheet for the first time.
The Antarctic sea-ice area fell to its lowest level on record, almost 1m km2 below the long-term average.
