Commentary: Can a Philosopher and a Scientist Co-teach a Class on Climate Engineering? – Thomas Ackerman & Stephen Gardiner

The answer to this question is ‘yes’ because we did it, so perhaps it is more appropriate to ask whether such a class can be taught successfully. Climate engineering provides an interesting, and perhaps disturbing, case study of the nexus of science (can we do it), ethics (should we do it), and governance (how would we do it). The idea of co-teaching a class on ethics and science focused on climate engineering originated with Steve Gardiner in mid-2013, leading to a class that we co-taught at the University of Washington during Winter Quarter 2015. Our intent here is to summarize our experience and provide some lessons learned.

The international human right to science and its application to geoengineering research and innovation- Kristin Barham & Anna-Maria Hubert

While many general human rights articulated in international law are of consequence for geoengineering research and development, the normative framework of the right to science has particular relevance. This right has the potential to enhance accountability, transparency and participation, particularly in addressing the socio-technical risks associated with early research and innovation processes.

Cost-Benefit Analysis of Solar Geoengineering – Garth Heutel, Juan Moreno-Cruz, and Soheil Shayegh

The advantages and disadvantages of solar geoengineering ought to be compared to each other using a cost-benefit analysis. While there has been much discussion about the trade-offs inherent in solar geoengineering, there has been surprisingly little quantitative, formal modeling of these trade-offs.

The ‘Lomborg gambit’ and why the allure of solar geoengineering must be resisted by the Paris negotiators – Prof John Shepherd CBE FRS and Andy Parker

Nothing we know about solar geoengineering should distract you from the task of agreeing deep and binding cuts in CO2 emissions, and effective support for adaptation to climate change. Ignore the siren calls of anyone who attempts another ‘Lomborg gambit’ by dangling solar geoengineering as an alternative to emissions cuts, and get on and agree the climate deal that we – and the planet – so desperately need.

What of 2C? – Aaron Kressig

Climate scientists have begun to calculate how we are doing on the 2C goal, and the math is a little frightening. Not only do we have little wiggle room in terms of how much carbon we can emit to have any certainty of staying under this limit, but it will be global actions in the next two decades that determine our fate.
