Harvard Project Conducts Research Workshop on Governance of Solar Geoengineering

| Oct. 26, 2018

The Harvard Project on Climate Agreements conducted a research workshop, “Governance of the Deployment of Solar Geoengineering,” September 27 – 28, 2018 at Harvard Kennedy School. Harvard’s Solar Geoengineering Research Program collaborated and provided support for the workshop.

An Economic Anatomy of Optimal Climate Policy

| August 2018

The authors introduce geoengineering into an optimal control model of climate economics. Together with mitigation and adaptation, carbon and solar geoengineering span all possible climate policies. Their wildly different characteristics have important implications for policy. They show in the context of their model that: (i) whether emissions are positive or zero the optimal carbon tax always equals the marginal cost of carbon geoengineering; (ii) the introduction of either form of geoengineering leads to higher emissions yet lower temperatures; (iii) in a world with above-optimal cumulative emissions, mitigation alone is insufficient and only a complete set of instruments can minimize climate damages.

This is an updated version of a paper first published in July 2017.

Confronting Deep and Persistent Climate Uncertainty

| July 2016

Estimates of damages from climate change are dependent on estimates of global-average-temperature increase, which in turn depend on how marginal increases in greenhouse-gas concentrations affect temperature. The "likely" range of temperature increase from a doubling of concentrations has stalled for 35 years at 1.5–4.5° C—making estimates of damages difficult and unreliable.

Climate Sensitivity Uncertainty: When is Good News Bad?

| September 2015

Uncertainty about "climate sensitivity"—the impact on temperature of increased concentrations of greenhouse gases—grew from the IPCC's 4th to 5th Assessment Reports. The authors conclude that this "bad news" outweighs the "good news": a lower value for the bottom end of the range for temperature rise.
