Ecoshock Radio: Climate Geoengineering and Chemtrails Conspiracy

"In this program we talk with one of the world's top experts on geoeningeering to cool the planet, Harvard's Dr. David Keith. Then from the UK, Dr. Rose Cairns investigates the internet phenomenon of chemtrails, the belief that aircraft are already poisoning the sky."

Science Daily: Geoengineering proposal may backfire: Ocean pipes 'not cool,' would end up warming climate

Media response to Kwiatkowski, Lester; et al. (2015). "A new study from a group of Carnegie scientists determines that these types of pipes could actually increase global warming quite drastically."

Shell Blog: Getting to net-zero emissions

On negative emissions/BECCS. "Both of the Shell New Lens scenarios end in a  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."

Phys.org: Ocean pipes 'not cool,' would end up warming climate

Media response to Kwiatkowski, Lester; et al. (2015). "The team, which also included lead author Lester Kwiatkowski as well as Katharine Ricke, configured a model to test this idea and what they found surprised them."

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?"

Grist: Why we should talk about geoengineering even if we never do it

"Ben Kravitz has studied geoengineering for the past seven years and doesn’t plan to stop anytime soon, despite ongoing controversy around the issue. That’s because even if geoengineering never happens in the real world, the concept alone is already playing an important role in the climate change story."
