Shell Blog: Getting to net-zero emissions

On negative emissions/BECCS. „Both of the Shell New Lens scenarios end in a[nbsp] net zero emissions outcome by the end of the century, but this is within the energy system itself and does not encompass the full range of other sources of CO2 emissions and other long lived greenhouse gases.“

Kwiatkowski, Lester; et al. (2015): Atmospheric consequences of disruption of the ocean thermocline

Kwiatkowski, Lester; Ricke, Katharine L.; Caldeira, Ken (2015): Atmospheric consequences of disruption of the ocean thermocline. In: Environ. Res. Lett. 10 (3), S. 034016. DOI: 10.1088/1748-9326/10/3/034016.

„To help bound potential climate consequences of these activities, we perform a set of simulations involving idealized disruption of the ocean thermocline by greatly increasing vertical mixing in the upper ocean. We use an Earth System Model (ESM) to evaluate the likely thermal and hydrological response of the atmosphere to this scenario.“

Discussion: Climate Engineering: Solution or Problem?

„Do leading climate engineering proposals offer a realistic form of response to climate change? What are the major scientific, political, and social challenges to climate engineering’s development? Do the potential benefits of climate engineering research outweigh the risk that it will be used as an excuse not to deal with carbon emissions today?“
