Gasser, T.; Guivarch, C.; et al (2015): Negative emissions physically needed to keep global warming below 2 °C

Gasser, T.; Guivarch, C.; Tachiiri, K.; Jones, C. D.; Ciais, P. (2015): Negative emissions physically needed to keep global warming below 2 °C. In nature communications 6, p. 7958–7958. DOI 10.1038/ncomms8958.

"Here, using state-of-the-art carbon–climate models, we quantify the trade-off between these two options in RCP2.6: an Intergovernmental Panel on Climate Change scenario likely to limit global warming below 2°C. In our best-case illustrative assumption of conventional mitigation, negative emissions of 0.5–3Gt C (gigatonnes of carbon) per year and storage capacity of 50–250Gt C are required. In our worst case, those requirements are 7–11Gt C per year and 1,000–1,600Gt C, respectively."
