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.
“The greater the warming, the worse the impacts,” said the WMO secretary-general, Prof Petteri Taalas. “We have such high levels of CO2 in the atmosphere now that the lower 1.5C [target] of the Paris Agreement is barely within reach. It’s already too late for many glaciers [and] sea level rise is a long-term and major threat to many millions of coastal dwellers and low-lying states.”
António Guterres, UN secretary-general, said ahead of Cop27: “Emissions are still growing at record levels. That means our planet is on course for reaching tipping points that will make climate chaos irreversible. We need to move from tipping points to turning points for hope.”
A series of recent reports signalled how near the planet is to climate catastrophe, with “no credible pathway to 1.5C in place” and the current level of action set to see no fall in emissions and global temperature rise by a devastating 2.5C.
