Maxwell, S. L.; et al. (2019): Degradation and Forgone Removals Increase the Carbon Impact of Intact Forest Loss by 626%

Maxwell, Sean L., Tom Evans, James E. M. Watson, Alexandra Morel, Hedley Grantham, Adam Duncan, Nancy Harris, et al. 2019. “Degradation and Forgone Removals Increase the Carbon Impact of Intact Forest Loss by 626%.” Science Advances 5 (10): eaax2546. https://doi.org/10.1126/sciadv.aax2546.

"We show that between 2000 and 2013, direct clearance of intact tropical forest areas accounted for 3.2% of gross carbon emissions from all deforestation across the pantropics. However, full carbon accounting requires the consideration of forgone carbon sequestration, selective logging, edge effects, and defaunation. When these factors were considered, the net carbon impact resulting from intact tropical forest loss between 2000 and 2013 increased by a factor of 6 (626%), from 0.34 (0.37 to 0.21) to 2.12 (2.85 to 1.00) petagrams of carbon (equivalent to approximately 2 years of global land use change emissions)."

Carbon Brief: Guest post by Prof. Duncan McLaren: The problem with net-zero emissions targets

"However, our newly published research – based on findings from expert interviews and stakeholder deliberations – suggests that combining emissions reductions and negative emissions into a single target of reaching “net-zero” may create problems. These could include delayed emissions cuts, but also insufficient focus on developing negative emissions technologies."

Smith, Laurence G.; et al. (2019): The greenhouse gas impacts of converting food production in England and Wales to organic methods

Smith, Laurence G.; Kirk, Guy J. D.; Jones, Philip J.; Williams, Adrian G. (2019): The greenhouse gas impacts of converting food production in England and Wales to organic methods. In Nat Commun 10 (1), pp. 1–10. DOI: 10.1038/s41467-019-12622-7.

"Here we assess the consequences for net GHG emissions of a 100% shift to organic food production in England and Wales using life-cycle assessment. We predict major shortfalls in production of most agricultural products against a conventional baseline."

The Economist: The right way to measure carbon emissions

"As public opinion shifts, politicians are reacting by adopting new policies. One of the most popular is to set targets to reach “net zero” carbon emissions within a defined geographical border."

EGU: Glacial engineering could limit sea-level rise, if we get our emissions under control

"Targeted engineering projects to hold off glacier melting could slow down the collapse of ice sheets and limit sea-level rise, according to a new study published in the European Geosciences Union journal The Cryosphere. While an intervention similar in size to existing large civil engineering projects could only have a 30% chance of success, a larger project would have better odds of holding off ice-sheet collapse. But study authors Michael Wolovick and John Moore caution that reducing emissions still remains key to stopping climate change and its dramatic effects."
