The year 2024 saw the fastest annual increases in CO\u2082 concentrations since direct measurements began, and the highest levels of methane (CH\u2084) and nitrous oxide (N\u2082O) in recorded history. This record increase led to a temporary breach of the 1.5\u00b0C threshold in 2024 and an increase in greenhouse gas radiative forcing of more than 50 % since 1990. The impacts include extreme weather events, global ocean warming, and significant health risks for both ecosystems and people. Fossil fuel combustion and massive forest fires remain the main sources of emissions, with global carbon emissions reaching new highs with no signs of slowing. Achieving the Paris goals requires immediate and deep emission reductions, protection of natural carbon sinks, and deployment of CO\u2082 capture and storage.<\/p>\n

Large-scale forest fires, partly driven by extreme heat and drought, are also increasing methane and CO\u2082 emissions, with forest fire emissions exceeding the 10-year average by 16 % in 2023. There is also a negative feedback loop from melting permafrost, which releases ancient organic carbon in the form of methane and CO\u2082 research.noaa.gov<\/span><\/a>. \u26a0\ufe0f Historical milestones and alarming values<\/strong><\/p>\n CO\u2082 concentrations are now at their highest in at least 800,000 years, confirmed by the WMO based on ice cores.

\nAtmospheric CO\u2082 levels reached about 420 ppm in 2023, 151 ppm above pre-industrial levels in 1750, according to the World Meteorological Organization. Methane (CH\u2084) reached 265 ppm above pre-industrial levels and nitrous oxide (N\u2082O) reached 124 ppm, which together with CO\u2082 account for most of the increase in radiative forcing.
