Zickfeld, Kirsten; et al. (2021): Asymmetry in the climate–carbon cycle response to positive and negative CO2 emissions

Zickfeld, Kirsten; Azevedo, Deven; Mathesius, Sabine; Matthews, H. Damon (2021): Asymmetry in the climate–carbon cycle response to positive and negative CO2 emissions. In Nat. Clim. Chang., pp. 1–5. DOI: 10.1038/s41558-021-01061-2.

“ It is commonly assumed that the climate–carbon cycle response to a negative CO₂ emission is equal in magnitude and opposite in sign to the response to an equivalent positive CO₂ emission. Here we test the hypothesis that this response is symmetric by forcing an Earth system model with positive and negative CO₂ emission pulses of varying magnitude and applied from different climate states.“
