Fear of Solar Geoengineering is Healthy — But Don't Distort Our Research

| Mar. 29, 2017

"Fear of solar geoengineering is justified. So is fear of the largely unaccounted-for tail risks of climate change, which make the problem much worse than most realise. Ending fossil fuels will not eliminate climate risks, it just stops the increase of atmospheric carbon. That carbon and its climate risk cannot be wished away.

There is a prudent case for an international, transparent, and sustainable solar geoengineering research programme that includes field experiments with appropriate governance."

Heads of State participate in the opening ceremony of the High-Level Event of COP 22, November 15, 2016.

Cop22 After Trump

| November 21, 2016

"...[E]ven if the impacts of a Trump slump in U.S. domestic climate action are manageable, the impact on global policy may not be. The concern here is not immediate support for new coal plants or the immediate risk of conflict; it is the way in which a weakening of international institutions might initiate a negative feedback loop played out over many years and decades."

To Help Cool the Climate, Add Aerosol

| October 5, 2016

"Of course, solar geoengineering alone cannot stabilize the climate. The world must cut carbon dioxide emissions. But solar geoengineering is unique because it can help address already committed climate change—future climate change locked in due to past emissions. Cutting carbon emissions alone will not have immediate effects, given the length of time that carbon already in the atmosphere stays there."

Implications of the Paris Agreement for Carbon Dioxide Removal and Solar Geoengineering

| July 2016

The authors explore, in particular, the implications for CO2 removal and solar geoengineering of the Paris Agreement's long-term temperature goals, provision for "removals by sinks," and market-based mitigation mechanisms.

Here’s a Way to Cool the Planet without Merely Reducing Emissions

| June 16, 2016

"China has initiated a limited research program on albedo modification. The U.S. has not. Given that albedo modification is the kind of technology that necessitates an open, transparent, and international research effort — precisely the kind of effort in which the U.S. excels — this is a serious failing."

What’s the right temperature for the Earth?

| January 29, 2016

Imagine being able to control the temperature of the Earth like a home thermostat, turning it down a few notches to reduce the effects of global warming. That’s the goal of solar geoengineering. By spraying aerosols into the stratosphere, we could block a fraction of inbound sunlight and temporarily cool the Earth.

But just as home thermostats are notorious for setting off domestic squabbles — she bumps it up to 72, he ratchets it down to 64 — solar geoengineering could spark serious conflicts, ranging from sanctions to war between world powers.

Paris Climate Conference 2015: A key step in stopping climate?

| Fall/Winter 2015-2016

Was the Paris Climate Conference of 2015 a key step in stopping climate change? We asked the Belfer Center's Robert Stavins and David Keith to give us their answers to that question. They agreed to disagree in some of their answers and comments.
