Berkeley News: Blocking sunlight to cool Earth won’t reduce crop damage from global warming

"Injecting particles into the atmosphere to cool the planet and counter the warming effects of climate change would do nothing to offset the crop damage from rising global temperatures, according to a new analysis by University of California, Berkeley, researchers."

Nature: Glacier geoengineering needs lawyers too

"Proposals such as those of John Moore and colleagues (Nature 555, 303–305; 2018) for Antarctic glacier geoengineering understate the legal challenges presented by the Antarctic Treaty System (ATS). This system is crucial to Antarctic governance, but faces considerable geopolitical pressure (Nature 558, 161; 2018). It is essential that any activities affecting the Antarctic ecosystem properly engage with the ATS from the outset."

Independent: Major plan to deal with climate change by geoengineering the Earth would not work, scientists reveal

"The Earth could not be changed to save the environment, according to a new paper exploring the possibilities of "geoengineering" the planet to protect us from the worst effects of climate change."

The Guardian: Reflecting sun's rays would cause crops to fail, scientists warn

"Proposals to combat climate change by reflecting the sun’s rays back into space would cause widespread crop failure, cancelling out any benefits to farming from the reduction in warming, according to new research."

Harper, A. B.; et al. (2018): Land-use emissions play a critical role in land-based mitigation for Paris climate targets

Harper, A. B.; Powell, T.; Cox, P. M.; House, J.; Huntingford, C.; Lenton, T. M. et al. (2018): Land-use emissions play a critical role in land-based mitigation for Paris climate targets. In: Nat Comms 9 (1), S. 405. DOI: 10.1038/s41467-018-05340-z.

"Here we show that additional land-use change to meet a 1.5 °C climate change target could result in net losses of carbon from the land. The effectiveness of BECCS strongly depends on several assumptions related to the choice of biomass, the fate of initial above ground biomass, and the fossil-fuel emissions offset in the energy system. Depending on these factors, carbon removed from the atmosphere through BECCS could easily be offset by losses due to land-use change. If BECCS involves replacing high-carbon content ecosystems with crops, then forest-based mitigation could be more eficient for atmospheric CO2 removal than BECCS."

Eos: Modeling the Effects of Geoengineering

"Geoengineering (deliberate, temporary modification of the climate system; also called climate intervention or climate engineering) is increasingly receiving attention as a field of study and a potential method of reducing the most severe negative effects of climate change. If decision-makers are going to seriously consider geoengineering as an option, they need to understand the risks of deploying geoengineering, as well as the risks of not doing so."
