The WMO’s annual State of the Climate Report, revealed Friday forward of Earth Day, is actually a well being checkup for the world.
It analyses a collection of world local weather indicators – together with ranges of planet-heating air pollution, sea stage rise and ocean warmth – to know how the planet is responding to local weather change and the influence it’s having on folks and nature.
The findings paint a stark image.
“2022 was a year of extremes for the planet – and this continues the trend set in previous years,” Omar Baddour, head of the Climate Monitoring and Policy Division on the WMO, instructed CNN.
A slew of local weather data have been damaged, lots of which have been, or are heading in the right direction to be, damaged once more this yr:
- Oceans reached record-high temperatures, with practically 60 per cent experiencing at the very least one marine heatwave.
- Global sea ranges climbed to the very best on document resulting from melting glaciers and warming oceans, which develop as they warmth up.
- Antarctica’s sea ice dropped to 1.92 million sq. kilometres in February 2022, on the time the bottom stage on document (the document was damaged once more this yr).
- The European Alps noticed a document yr for glacier soften, with Switzerland notably badly affected, shedding 6 per cent of its glacier quantity between 2021 and 2022.
Levels of planet-warming air pollution, together with methane and carbon dioxide, reached document highs in 2021, the most recent yr for which there’s world knowledge.
These broad local weather indicators are an necessary reflection of the state of the planet, the report famous, however excessive climate occasions – fueled by local weather change – are the place the quick results are most felt.
‘Climate laggard’: Nations finest and worst on inexperienced future checklist
“While greenhouse gas emissions continue to rise and the climate continues to change, populations worldwide continue to be gravely impacted by extreme weather and climate events,” WMO Secretary-General Petteri Taalas stated in a press release.
Last yr, local weather change-fueled excessive climate “affected tens of millions, drove food insecurity, boosted mass migration, and cost billions of dollars in loss and damage,” he stated.
In 2022, China had its most in depth and long-lasting drought on document.
Droughts additionally affected East Africa, with greater than 20 million folks in Ethiopia, Kenya and Somalia going through acute meals insecurity as of January this yr.
Many western and southern US states skilled important drought and Europe’s punishing heatwave is estimated to have led to fifteen,000 extra deaths.
In Pakistan, record-breaking rainfall left large swaths of the nation underwater, killing greater than 1700 folks, with virtually eight million displaced, and inflicting $30 billion in damages.
The most susceptible are the toughest hit, Baddour stated.
“Communities and countries which have contributed least to climate change suffer disproportionately.”
Last yr is unlikely to be an outlier, as temperatures proceed their upwards trajectory.
The previous eight years have been the most well liked on document, regardless of three consecutive years of the La Niña local weather phenomenon, which has a worldwide cooling impact.
The world common temperature final yr climbed to about 1.15 levels above pre-industrial ranges, in accordance with the report, because the world continues its march in the direction of breaching 1.5 levels of warming for the primary time.
With the anticipated arrival later within the yr of El Niño, which brings hotter world temperatures, scientists are deeply involved that 2023 and 2024 will proceed to smash local weather data.
The hottest yr on document, 2016, was the results of a powerful El Niño and local weather change, stated Baddour.
“It is only a matter of time before that record is broken.”
The WMO report follows an evaluation revealed on Thursday by the European Union’s Copernicus Climate Change Service, which centered on how local weather change affected Europe final yr.

It highlighted “alarming” adjustments to the continent’s local weather, together with the most well liked summer season ever recorded, unprecedented marine heatwaves within the Mediterranean Sea and widespread wildfires.
“The droughts and level of heatwaves that we saw throughout 2022 were quite remarkable,” Samantha Burgess, deputy director of Copernicus, instructed CNN.
“This is really a wake-up call that climate change isn’t a future problem, it is a current problem. And we need to adapt as quickly as possible,” she added.
