The largest ever recorded leap in the amount of carbon dioxide laden in the world’s atmosphere has just occurred, according to researchers who monitor the relentless accumulation of the primary gas that is heating the planet.
The global average concentration of carbon dioxide in March this year was 4.7 parts per million (or ppm) higher than it it was in March last year, which is a record-breaking increase in CO2 levels over a 12-month period.
