Open in full screen “Fossil fuel pollution is causing unprecedented climate chaos,” says UN Secretary-General. Agence France-Presse There is a “high probability” that 2024 will in turn display unprecedented temperatures, while the past year concludes a decade of record heat, pushing the planet “to the brink of the abyss”, the UN warned on Tuesday. 
The report confirms that 2023 was the hottest year on record, with an average global surface temperature of 1. 45°C above the pre-industrial baseline.
A new report from the World Meteorological Organization (WMO), a UN agency, shows records were broken this year. last year, and in some cases even shattered, when it comes to greenhouse gas levels, surface temperatures, heat content (the energy absorbed and stored) and ocean acidification , sea level rise, the extent of the Antarctic sea ice and the retreat of glaciers.
We can't say for sure, but I would say there is a high probability that 2024 will break the 2023 record again, Omar said Baddour, from the WMO, at a press conference.
The planet is on the brink of collapse as fossil fuel pollution causes unprecedented climate chaos, UN Secretary-General Antonio Guterres warned in a video message, while estimating that it is still time to throw a lifeline to people and the planet.

Every fraction of a degree of global warming has an impact on the future of life on Earth.
A quote from Antonio Guterres, Secretary General of the UN
The climate crisis is THE defining challenge facing humanity and is inextricably intertwined with the inequality crisis, as evidenced by growing food insecurity, population displacement and loss of biodiversity, added the Secretary General of WMO, Celeste Saulo.
Heat waves, floods, droughts, wildfires and the rapid intensification of tropical cyclones are sowing misery and chaos, disrupting the daily lives of millions of people and inflicting economic losses worth billions of dollars, alerts the WMO.
This is also the hottest decade (2014-2023) ever observed, exceeding the average 1850-1900 of 1.20°C.
The rise in global temperature over the long term is due to the increase in concentration of greenhouse gases in the atmosphere, which reached record levels in 2022.
The arrival of the El Niño phenomenon in mid-2023 also contributed to the rapid rise in temperatures, according to the WMO.
According to Ms. Saulo, we have never been so close – although temporarily for the moment – to the lower limit set at 1.5 °C in the Paris Agreement on climate change.
The global meteorological community warns the whole world and sounds the alarm: we are on red alert.
A quote from Celeste Saulo , Secretary General of WMO
Last year, nearly a third of the world's oceans were in the grip of a marine heatwave. By the end of 2023, more than 90% of the world's oceans had experienced heat waves at some point during the year, according to the WMO.
Increased frequency and intensity of marine heatwaves are having profound negative impacts on marine ecosystems and coral reefs.
< p class="StyledBodyHtmlParagraph-sc-48221190-4 hnvfyV">Furthermore, the average sea level on a global scale reached a record level in 2023, which reflects the continued warming of the oceans (thermal expansion) as well as the melting of glaciers and ice sheets. p>
A worrying sign, the rate of rise of this average level over the last decade (2014-2023) is more than twice as high as that of the first decade of the satellite era (1993-2002). largest recorded since 1950, after extreme melting in western North America and Europe, according to preliminary data.
There is, however, a glimmer of hope, according to the WMO: renewable energy production capacities in 2023 increased by almost 50% year-on-year, the highest rate observed over the past two decades.
