Last year marked a record surge in atmospheric CO2 levels, with an increase of 3.36 parts-per-million, which is about 10% higher than any previous record, and added an unprecedented 26 billion tonnes of CO2 to the atmosphere. This rate of increase is substantially faster than during the transition from the last ice age, highlighting a dramatic acceleration away from climate stability.

Efforts to achieve net zero CO2 emissions are critical as even minor increases can have significant global climate impacts, reminiscent of historical periods that radically altered Earth’s climate. The consistent rise in CO2 levels over decades illustrates the urgent need to reach net zero emissions to prevent increasingly severe consequences of climate change and ocean acidification.
