The claim
Il existe actuellement 29 volcans qui rejettent 120 000 tonnes de CO₂ par jour dans l'atmosphère, mais les pets de vaches changent le climat ?
Original publisher’s rating
Sur base annuelle, les émissions de CO2 causées par les activités humaines (dont l'agriculture) sont environ 100 fois supérieures à celles des volcans. L'impact des émissions volcaniques sur le climat est en outre de courte durée.

The claim misleadingly compares volcanic CO₂ emissions with emissions from human activities, including agriculture. The review says human-caused emissions are about 100 times greater annually, and volcanic effects on climate are short-lived.[S1]
Additional context
The review reports that human activities produce about 40 gigatonnes of CO₂ annually, compared with roughly 300–400 megatonnes from volcanoes; it describes volcanic emissions as about 1% of human-caused emissions. [S1]
According to the review, volcanic climate effects last no more than one or two years, unlike the long-lasting effects of human greenhouse-gas emissions. [S1]
