Both carbon dioxide (CO2) and methane (CH4) are increasing in the atmosphere due to human activities, but methane is increasing at a faster rate than carbon dioxide. Methane is a more potent greenhouse gas than carbon dioxide, but it is less abundant in the atmosphere, so its overall impact on global warming is still lower than that of carbon dioxide. However, the rapid increase in methane emissions is a concerning trend that needs to be addressed to mitigate climate change.
