AMSTERDAM – Met 400 ppm koolstofdioxide in de lucht heeft de wereld een nieuw record gezet. Nooit eerder was het aantal koolstofdioxidedeeltjes in miljoenen jaren zo hoog.

Een CO2-stikker aan de muurAmerikaanse meteorologen maakten afgelopen week een melding van de nieuwe mijlpaal. De metingen naar koolstofdioxide worden gedaan sinds 1958. Ieder jaar neemt het koolstofdioxidegehalte toe.

De afgelopen tien jaar nam het aantal deeltjes honderd keer zo snel toe als het geval was bij het einde van de ijstijd, toen de aarde ook opwarmde. De concentratie steeg in de afgelopen veertig jaar van 320 ppm naar 400 ppm.
