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.

Reflecting on the “Berlin Declaration” – Andy Parker (with Oliver Morton and George Collins)

The Climate Engineering Conference 2014 (CEC14) was the largest geoengineering meeting to date, bringing over 350 people together in Berlin in August 2014. The most prominent controversy at CEC14 was the introduction of a document – the “Berlin Declaration” –that those attending could choose to support. The document, drafted by representatives of the Oxford Geoengineering Programme, suggested some steps forward for governing solar geoengineering research. The story of the response to this document and its eventual withdrawal should hold interest for anyone concerned with the governance of emerging technologies or openness in science policy
