Re: [geo] Michael Mann: How Close Are We to ‘Dangerous’ Planetary Warming?

Mann’s ‘CDR only after reduction is agreed to have failed’ is an example of transitional rhetoric. An enormous number of activists have seen discussion of CDR as a distraction, as undermining the team strategy, and in extreme cases as a stab in the back – even though they’ve seen how

[geo] What are the most pressing questions on Moral hazard?

I'm interested in the issue of moral hazard. There's been a little work done on this (eg by NERC, Merk et al.) However, it seems to have slipped off the agenda of the geoengineering community recently. I hear less mention of it now than I did a few years ago. I'm interested in researching it

[geo] Re: What are the most pressing questions on Moral hazard?

Hi Andrew, I just stumbled over the following study linking changes in perception of climate change risk to presentation of geoengineering options. Interested? http://www.culturalcognition.net/browse-papers/geoengineering-and-the-science-communication-environment-a-c.html Brian On Saturday,

Re: [geo] What are the most pressing questions on Moral hazard?

If by "geoengineering" you include CDR, then perhaps the reason this has "slipped off the [moral hazard] agenda" is that CDR has been officially declared essential to stay <=2C (IPCC et al.). There is now a moral hazard of not pursuing CDR(?) The more interesting question might be is there also

Re: [geo] List of current Geoengineering?

Calling prevention of desulfurization an example of geo-engineering seems excessively broad. That would mean "geo-engineering" includes any policy respecting emissions adopted with the intent to influence forcing due to emissions. And that would include policies to reduce GHG emissions. As

Re: [geo] List of current Geoengineering?

For clarity, it's *preventing* the desulfurization of marine fuels that would be geoengineering. There's a strong case for cleaning them up, as they're very polluting and kill many people near ports. A On 26 Dec 2015 14:14, "NORTHCOTT Michael" wrote: > If desulfurizing

Re: [geo] List of current Geoengineering?

If desulfurizing marine fuels is geoengineering then any activity instigated to contribute to mitigation of anthropogenic climate change becomes geoengineering (rendering the term almost meaningless) including becoming a vegetarian (because of the significant climate impacts of meat rearing) or

Re: [geo] List of current Geoengineering?

Alan, I actually feel this is a legitimate line of discussion for the GE group. Let's look, for example, at the issue of marine bunker fuels. They're currently being desulfurized, and this will have climate impacts. I think it's legitimate to describe this as 'geoengineering' - to the extent
