Re: [geo] IPCC: CDR must be considered
I agree that CDR needs a separate discussion. I'm not too keen on negcarbon or CDR since air CO2 can be managed/decreased by reducing natural emissions as well as increasing air CO2 removal. Something like Air CO2 Management might be OK, but then I don't think we want to include things like CCS. So am supportive, if we have a critical mass and can compete with existing e-discussions e.g. biochar and geo.

Re: [geo] IPCC: CDR must be considered
Mark, Greg, Andrew, List Yes to such a group. I offer a motion that you should be the moderator - and hope I have a second. In biochar circles, there is a search for a word to replace “negative” - as not sending as positive a message as we would like. Maybe need some discussion on the “NegCarbon” name. Some group has started to use GGR = Greenhouse Gas Removal - a little broader than CDR. But I am comfortable enough with CDR. I would love to see the “Neg” concept, just not the word “Negative”. I still see no (early easy) way to remove CDR (or NET or GGR) from the definition of “Geoengineering”. I’d rather see biochar (speaking off the record for only one CDR approach) being discussed on this list than not. See also below.

[RWL: See above.] It appears we need to create a firewall (canyon, mountain, ocean, big obstacle) between geo- and climate-engineering and CDR, Negative Carbon Technologies, or whatever we call them. We don't want people hearing or seeing mentions of CDR in the same paragraph with climate-engineering (the SRM, clouds, mirrors, OIF, etc.) [RWL: I’m torn. I don/t mind seeing them together. What really bothers me is use of the term “geoengineering” when what is meant is SRM. David Keith does that, but he warns people in the opening of his book, so that is OK. In that book, but I think it still would be better to always be clear on what is being discussed. Yesterday’s discussion of the Reuter article is a case in point. I don’t see how we can promote CDR without having a comparison with SRM - in quantitative terms. Better if most mentions of NegCarbon are in paragraphs and articles discussing mitigation or adaptation. [RWL: Hmm. I guess I understand your point. CDR/GGR is in addition to, not either/or.

I hope I have never suggested any CDR/GGR approach should be off the list. There is plenty of CO2 to go around.

Temperatures have already risen by 0.8C since the Industrial Revolution. Bioenergy To limit warming, the report estimates the world would have to invest an extra $US147 billion ($164 billion) a year in low-carbon energies, such as wind, solar or nuclear power from 2010 to 2029. At the same time, investments in fossil fuel energy would have to be reduced by $US30 billion annually. And several hundred billion dollars a year would have to go on energy efficiency in major sectors such as transport, buildings and industry. By contrast, it said that global annual investments in the energy system are now about $US1.2 trillion. And it says there are huge opportunities for cleaning up, for instance by building cities that use less energy for a rising world population. Most of the world's urban areas have yet to be constructed, it says. Overall, the report estimates that the costs of combating global warming would reduce global consumption of goods and services by between 1 and 4 per cent in 2030, 2-6 per cent in 2050 and 2-12 per cent in 2100, compared to no action. The IPCC said in September that it is at least 95 per cent probable that human activities, led by the burning of fossil fuels, are the dominant cause of global warming since the 1950s, up from 90 per cent in a 2007 assessment. The world has agreed to work out a global U.N. deal by the end of 2015, entering into force from 2020, to fight climate change. But progress has been sluggish. Global greenhouse gases have risen more rapidly between 2000 and 2010, the draft says, with greater reliance on coal than in previous decades. China, the United States and the European Union are the top emitters. The IPCC cautioned that the findings in the draft, dated Dec. 17, were subject to change. This is a work in progress which will be discussed and revised in April, said Jonathan Lynn, spokesman for the IPCC in Geneva. The report adds many details to earlier drafts. The IPCC's credibility suffered in 2007 after one of its reports wrongly said that Himalayan glaciers could all melt by 2035, centuries earlier than experts reckon. The draft says that only the most radical curbs outlined in an IPCC report in September would give a better than 66 per cent chance of keeping temperature rises below 2C. The scenario corresponds to greenhouse gas concentrations of 430 to 480 parts per million in the atmosphere - up from about 400 now.
