20:4220:42, 14 January 2016 diff hist +604 Talk:Climate engineering →Solar radiation management versus carbon dioxide removal
20:2820:28, 14 January 2016 diff hist +909 Climate engineering →Governance: Make the critical point that, because carbon dioxide removal and solar radiation management differ in fundamental ways, they entail fundamentally different governance challenges.

16:2916:29, 4 January 2016 diff hist +254 Climate engineering →Politics and Governance: The quote from Bengtsson applies only to certain situations and is clearly untrue generally speaking.
16:1116:11, 4 January 2016 diff hist −1,208 Climate engineering →Ethics and responsibility: Deleted an incoherent paragraph that did not pertain to ethics.
15:5815:58, 4 January 2016 diff hist +150 Climate engineering →Tipping points and positive feedback: Conventional wisdom among experts is that this sort of runaway scenario is highly unlikely -- see reference.
15:4615:46, 4 January 2016 diff hist 0 m Climate engineering →Governance: All such attempts, e.g., Russ George, Climos, Planktos, have been ocean fertilization projects.
15:4015:40, 4 January 2016 diff hist +154 Climate engineering "Buying time" is distinct from "tipping points" as a justification for climate engineering.

13:4913:49, 20 November 2015 diff hist +6 m Climate engineering Revised language to clarify that it is the creation of biochar, not its application to soil, that achieves carbon removal.

18:5818:58, 18 November 2015 diff hist −29 m Climate engineering Deleted "carbon sequestration" because all CDR projects by definition entail carbon sequestration.
18:5418:54, 18 November 2015 diff hist −11 m Climate engineering Deleted reference to "paving" in definition of "cool roof" as it is a separate technique.

19:4119:41, 20 July 2015 diff hist +64 m Stratospheric aerosol injection →Injection regime: Specified the condition required in order for the claim about commitment to hold.

17:1817:18, 23 June 2015 diff hist +567 Stratospheric aerosol injection Added updated information on modified civilian aircraft delivery vehicles.
16:4016:40, 23 June 2015 diff hist +2 m Stratospheric aerosol injection Changed "fighter aircraft" to "high-altitude aircraft." Authors write only of "jet-fighter-sized aircraft"--real issue is altitude (stratosphere).
