PARIS: Greenhouse gas concentrations in the atmosphere reached new record highs in 2023, the UN warned on Monday, with countries falling “miles short” of what is needed to curb devastating global warming.
Levels of the three main greenhouse gases -- heat-trapping carbon dioxide, methane and nitrous oxide -- all increased yet again last year, said the World Meteorological Organisation, the United Nation´s weather and climate agency.
Emissions, largely from the burning of fossil fuels, have continued a relentless rise in recent years, even as rising temperatures unleash increasingly damaging and costly extreme weather across the globe.
A separate report by UN climate change found that barely a dent is being made in the 43 percent emissions cut needed by 2030 to avert the worst of global warming. Action as it stands would only lead to a 2.6 percent reduction this decade from 2019 levels.
“Current national climate plans fall miles short of what´s needed to stop global heating from crippling every economy, and wrecking billions of lives and livelihoods across every country,” said UN climate chief Simon Stiell. The two reports come just weeks before the United Nations COP29 climate summit in Azerbaijan, and as nations prepare to submit updated national climate plans in early 2025.
