\ud83e\udd75 CO\u2082 concentrations in the atmosphere have reached new records despite the relative stabilization of emissions, with human carbon emissions stagnating at around 10.2 GtC per year, but natural carbon sinks (forests, soils, oceans) they can no longer absorb such huge amounts of CO\u2082. The year 2024 brought a year-on-year increase in atmospheric CO\u2082 of 3.5 ppm (from 420.5 ppm to 424 ppm), the fastest jump in the history of measurements, and it was also found that intensified fires and widespread droughts significantly weakened the biosphere's capacity to absorb carbon.<\/p>\n

1. Stabilization of emissions vs. growth of concentration<\/strong><\/p>\n

Human CO\u2082 emissions from fossil fuels and land-use change have averaged over the past decade 0.6 % per year<\/strong>, down from 2 % in the previous decade. Nevertheless, annual emissions are still record highs 10.2 GtC<\/strong> (37.4 GtCO\u2082) in 2024 (Global Carbon Budget<\/a><\/span>). However, atmospheric CO\u2082 concentration increased on average by 2.4 ppm\/year<\/strong> over the past decade and jumped by 2024 3.5 ppm<\/strong> on the 424 ppm<\/strong>, which is more than 50 % more than pre-industrial levels (~280 ppm) (NOAA<\/a>, EarthSky<\/a><\/span>).<\/p>\n
