Short summary
Fauna and flora respire carbon dioxide into the atmosphere, which is a major carbon flux into the atmosphere. The underlying biochemical processes are complex, and we generalize them either assuming a first-order chemical reaction of carbon and oxygen to carbon dioxide or assuming enzymatic reactions. Here, we show that these assumptions lead to large differences in estimating the carbon–climate feedback until 2100 and the remaining carbon budget to keep warming below 2°C.
