Heutel, Garth; et al. (2017): Solar Geoengineering, Uncertainty, and the Price of Carbon

Heutel, Garth; Moreno-Cruz, Juan; Shayegh, Soheil (2017): Solar Geoengineering, Uncertainty, and the Price of Carbon. In Journal of Environmental Economics and Management. DOI: 10.1016/j.jeem.2017.11.002.

"We consider the socially optimal use of solar geoengineering to manage climate change and its implications for carbon emissions abatement policy. We show that solar geoengineering is a substitute for emissions abatement; optimal policy includes less abatement, by up to eight percentage points, and has a lower carbon price, by up to fifteen percent, than recommended by models that ignore solar geoengineering. However, it is an imperfect substitute, since it reduces temperature without reducing atmospheric or ocean carbon concentrations."

Harvard Political Review: The Earth in Our Hands: Geoengineering’s World-Changing Prospects

"Perhaps geoengineering is simply inevitable. As Caldeira, echoing one of his colleagues, astutely observed, “When has humanity ever developed the ability to control its environment and then not exercised that control?” The world must quickly engineer a solution to the climate crisis, and geoengineering provides a possible answer."

Third Way: Negative Emissions Primer

" fact, today, we’ve already gone through about 73% of our carbon budget (aka how much carbon can be in the air before warming rises to an unsafe level). We can and should ramp up deployment of clean energy technologies. But, we also have a secret weapon that many experts think we’ll absolutely need to keep warming to a safe level: negative emissions technologies."

Eco: This is Not a Drill: Geoengineering is on the Rise

"ECO recalls that in addition to ethical concerns about manipulating the Earth’s thermostat, SRM does not reduce GHG emissions, air pollution, or marine acidification; and it could undermine sustainable development goals. Furthermore, if SRM deployment were to begin on a significant scale it would be hard to stop, since its postulated effects of cooling are not permanent and it could trigger resurgent global warming if greenhouse gas concentrations continue to rise or remain at historically high levels."

Science Daily: Huge carbon sink in soil minerals: New avenue for offsetting rising greenhouse gases

"Soil holds more than three times the carbon found in the atmosphere, yet its potential in reducing atmospheric carbon-dioxide levels and mitigating global warming is barely understood. A researcher has discovered that vast amounts of carbon can be stored by soil minerals more than a foot below the surface. The finding could help offset the rising greenhouse-gas emissions helping warm the Earth's climate. "
