After Paris, time for an honest conversation – Simon Nicholson

In this brief video message, Simon Nicholson, Co-Director of the Forum for Climate Engineering Assessment, argues that after CoP 21 in Paris, we must have more honest assessment of goals and the tools available to us. This means, he argues, a need for open consideration of ideas that to this point have largely been seen…

Aligning conceptions of geoengineering for a healthy climate conversation – Noah Deich

The mismatch between the academic and popular conception of geoengineering can muddle the conversation on whether/how we should be pursuing geoengineering solutions to climate change. If academics and non-academics think geoengineering is two different things, productive conversation about appropriate policy and regulatory pathways for the various climate solutions that potentially fall under the geoengineering umbrella is unlikely to emerge.

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.

Time to stop talking about “climate engineering” – Clare Heyward

My comment is meant to express a concern about how “climate engineering” is typically presented, initially at least, as set apart from other kinds of responses to climate change and even as raising “new” or “distinctive” ethical problems. I realise that this situation is changing somewhat, so to try to help it on its way, here is why I personally endorse a move away from talking about “climate engineering” in favour of talking about the many separate technologies that are currently herded together under that label. I realise this makes things rather messy, but I also think that messiness is a perennial feature of climate change politics.

Imperative to get the carbon removal dialogue up to speed with the science – Guest Post – Noah Deich, UC Berkeley

  On November 4th, Michael Ashcroft, of the Carbon Trust, and I gave a presentation on the topic of technologies for removing carbon from the atmosphere and their implications for industry and government, at the USEA, in Washington, D.C.  Negative emissions, or Carbon Dioxide Removal (“CDR”) activities have recently gained increased press attention in the mass media…

New study assesses potential challenges to BECCS deployment – Wil Burns

Recent studies make it increasingly clear that the globe is poised to blow past the 2°C “guardrail” that climate scientists and Parties to the UNFCCC have identified as critical to avoid dangerous climatic impacts, with current projections of temperature increases of 3-4°C or more by the end of the century. Such sobering scenarios have intensified…

Forum – Where does the climate geoengineering conversation go from here?

  On Monday, The New York Times ran a story titled “Climate Tools Seek to Bend Nature’s Path.” From the article- “Once considered the stuff of wild-eyed fantasies, such ideas for countering climate change — known as geoengineering solutions, because they intentionally manipulate nature — are now being discussed seriously by scientists. … That does not…
