-Stratospheric aerosol injection could stop or reverse global warming with direct costs of \$1-10 billion per year. The total global benefit from this would be roughly \$1-10 trillion per year by mid-century. Individual large countries seem to estimate the value of preventing climate change(( In this page, 'global warming' specifically refers to changes in the global average temperature, while 'climate change' refers to all of the human-caused changes to the climate. For example, ocean acidification would be climate change but not global warming. Most of the effects of climate change are mediated by the average temperature, so there is less than a factor of two difference between the costs of climate change and the costs of global warming. This does not significantly affect order of magnitude estimates.)) to be at least tens of billions of dollars per year.+Stratospheric aerosol injection could stop or reverse global warming with direct costs of \$1-10 billion per year, compared to global benefits of roughly \$1-10 trillion per year by mid-century and at least tens of billions of dollars per year for large countries.
  
 Large countries do not implement geoengineering because not enough research has been done to know that the risks are small. Geoengineering research is prevented by a majority of climate scientists' opposition, which makes it harder to get funding, and by certain environmental groups that advocate against specific experiments. Large countries do not implement geoengineering because not enough research has been done to know that the risks are small.

Some oil companies have been willing to spend tens of millions of dollars per year on climate denial (not enough for geoengineering) and some have been willing to spend a few billion dollars per year on green investments (maybe enough for geoengineering). //Additional Barriers:// Oil companies might face backlash if they started doing geoengineering and lose access to some of their important markets. //Stakes:// The net benefits seem marginal, so it is not surprising that other factors dominate.+  * **Private Oil Companies.** The annual profit of the largest oil companies is \$10-25 billion. //Benefits:// Their market might be eliminated by other efforts to prevent climate change. To roughly estimate the scale of the value of avoiding these costs, we can look at what they are willing to pay to avoid them.

 The efforts against geoengineering have operated on three levels: in published papers, in outdoor experiments, and in implementation. Each level precedes and precludes the later levels. The efforts against geoengineering have operated on three levels: in published papers, in outdoor experiments, and in implementation.

-Prior to 2006, there was a taboo against publishing scientific papers about geoengineering. Crutzen, an editor of the journal Climate Change, broke this taboo and people began to consider geoengineering to be a legitimate object of scientific inquiry.((Crutzen. //Albedo Enhancement by Stratospheric Sulfur Injections: A Contribution to Resolve a Policy Dilemma?// Climate Change **77**. (2006) p. 211-219. [[https://link.springer.com/content/pdf/10.1007%252Fs10584-006-9101-y.pdf%20%20]].)) Prior to 2006, only 1-2 papers on geoengineering were being published per year, while by 2009, over 50 papers were being published per year.((Oldham et al. //Mapping the Landscape of Climate Engineering.// Philosophical Transactions of the Royal Society A.

 Currently, no outdoor experiments for stratospheric aerosol injection are being done. Since 2010, there have been two attempts at doing these outdoor experiments, but neither experiment happened.

-  * When geoengineering experiments are proposed, certain environmental groups((Especially the ETC Group and the Friends of Earth.)) rally to oppose them. These environmental groups work with indigenous groups, when possible, to convince advisory committees and governments to not allow the research to proceed.+  * When geoengineering experiments are proposed, certain environmental groups((Especially the ETC Group and the Friends of the Earth.)) rally to oppose them.

 No country or international consortium has attempted to implement geoengineering. Two of the most common arguments against it, found in both scientific and policy papers,((Huttunen et al. //Emerging policy perspectives on geoengineering: An international comparison.// The Anthropocene Review 2(I). (2015) p. 14-32. [[https://journals.sagepub.com/doi/pdf/10.1177/2053019614557958]].)) do not seem sufficient to completely explain this: No country or international consortium has attempted to implement geoengineering.
