Geo-engineering: Implications for International Stability

The security and climate community must plan for the prospect of unilateral geo-engineering. As the consensus that climate change is real grows, geo-engineering has recently emerged as a possible policy option. Foreign Affairs last month has an excellent article detailing the projected costs of geo-engineering that states:

“…just one kilogram of sulfur well placed in the stratosphere would roughly offset the warming effect of several hundred thousand kilograms of carbon dioxide…there is general agreement that the strategies are cheap; the total expense of the most cost-effective options would amount to perhaps as little as a few billion dollars, just one percent (or less) of the cost of dramatically cutting emissions.”


From the view of that state, geo-engineering c
ould be the rational and affordable choice if global carbon emissions continue to grow. Countries like the US have the infrastructure to withstand severe storm damage or disease outbreak. Most of Africa does not. Last year, the Council on Foreign Relations published a report discussing this scenario. Key passage:

“A nation that has not done much to prepare, either in reducing its contributions to global emissions or in building adaptive capacity, might conclude that the consequences of climate change had become sufficiently severe that it was going to unilaterally engage in geoengineering – imposing large negative externalities on the rest of the world in order to reduce its own impacts.”


If climate change continues largely unabated, what’s to stop a country facing monsoon after monsoon from unilaterally trying to cool the Earth? For “$25 billion and $50 billion a year a country could repeatedly emit sulfur dioxide into the atmosphere to keep reflecting solar radiation despite the acid rain and unpredictable effects on plant growth for the rest of the world


The disparity between which states have the highest emissions and are the most able to adapt to climate change and the states who have low emissions but are the most vulnerable raises the prospect of rogue geo-engineering or attempts by states vulnerable to climate change to persuade more developed states who can afford it.

China or Russia are better equipped to develop geo-engineering technology and could do it with less fear of international sanction. Coincidentally, these countries have been resistant to cut back their emissions. Russia’s vulnerable economy benefits from high demand for natural gas and oil; China’s government has experimented with geo-engineering for decades. Cooling the planet is also much cheaper than cutting carbon emissions, which require large scale changes in transportation, energy and manufacturing. Regardless of which country is geo-engineering, there is no way for geo-engineering’s effects to be restricted. There are inevitable externalities that may cause global conflict and tension.

Hence, large scale research and development of geo-engineering technologies must coincide with effective international governance to prevent the possibility of “rogue” geo-engineering. Even better, making necessary cuts in carbon emissions would preclude the need to riskily geo-engineer.

UN Conference in Copenhagen

After a brief luncheon, the conference moved into a third plenary session, chaired by Alexander Nicoll, the IISS Director of Editorial. This session, titled: “The UN Climate Change Conference in Copenhagen: Should we reassess how ‘security’ is defined for a warming world? Can a UN agreement in Copenhagen guarantee long-term climate security?” Panelists included: Ambassador Steffen Smidt, the Royal Danish Ministry of Foreign Affairs’ Representative for Climate Change Issues; Ambassador Paula Dobriansky, the former Under Secretary of State for Global Affairs throughout the Bush Administration; and James Lee, a Professor in the School of International Service at American University.

Ambassador Smidt began the panel by saying that “an ambitious global climate deal” at December’s summit of the UN Framework Convention on Climate Change (UNFCCC) is a top priority for the Danish Government. He stated that climate change is more than just an environmental issue to be addressed at UNFCCC conferences. Instead, it must be addressed comprehensively throughout the government. He laid out a series of areas in foreign policy that should be addressed, including in multilateral forums, development financing, energy security, and international investment policy.

Ambassador Dobriansky focused on the necessity of negotiating a truly global emissions-reduction treaty that is both environmentally effective and comprehensive. It must not undermine the ability of poor countries to develop, but it cannot simply allow large developing nations to continue their emissions with no limits. Unlike Kyoto, any treaty must include real commitments from developing nations that are “Measurable, reportable, and verifiable.” Beyond the environmental effectiveness of a treaty, a successful Copenhagen summit will include new efforts to develop clean technology, will protect against deforestation, and will help to foster good government policies. Finally, Ambassador Dobriansky concluded that the world will not need a new global institution to protect the environment, as the UN process – though in need of reform – will prove sufficient to handle the task.

As the last presenter of the day, Professor James Lee gave a thought-provoking presentation on the long-term security risks of climate change, based on a new book, entitled Climate Change and Armed Conflict: Hot and Cold Wars. Using a map of the Intergovernmental Panel on Climate Change’s projections overlaid with a map of the world’s largest security risks, he made a persuasive case that – unless global warming is successfully mitigated – the world faces a range of new and potentially very dangerous security threats. Some specific scenarios that he mentioned included an end to ice caps and glaciers, the creation of an integrated ‘Great World Desert’ that stretches 600 miles from the Kalahari in Namibia to the Gobi in Mongolia, the specter of rising sea levels that could swamp existing islands and low-lying deltas, and the possibility of countries aggressively trying to change local and international weather patterns through cloud seeding or other geoengineering processes. Lee’s presentation underscored the long-term necessity of actively addressing climate change before these dire forecasts come to pass.

Overall, the questions surrounded how to achieve a successful result in Copenhagen. Several questioners asked how to involve China; the consensus was that it must be done in every way possible, including regional, multilateral, and bilateral agreements. All panelists agreed that the issue of how to enforce any agreements would be an important part of an agreement. One questioner asked why nations should continue to negotiate in the UNFCCC, when the Major Economies Forum, involving the 17 largest global emitters (85% of emissions), is moving towards crafting its own agreement. Dobriansky answered that it was most important to build capacity and governance through the UN process. All panelists agreed that, in the short-term, the UN process is sufficient, and there is no need for a new international environmental enforcement body. This panel provided important detail in how the international community could move towards a comprehensive treaty at December’s Copenhagen Conference, and it also talked about the dangers if we fail to act.

Scientists are growing increasingly worried about the policy response to climate change

Top climate scientists from around the world are gathering in Copenhagen on 10-12 March to call attention to the growing sense of urgency arising from recent scientific findings. Media coverage of the event has highlighted the scientific community’s increasing fear that currently planned mitigation measures may not be enough to prevent dangerous levels of global warming.

This has led to some scientists advocating a serious look into ‘Plan B’ options, such as geoengineering (that is, the deliberate manipulation of the Earth’s natural processes to reduce the impacts of climate change). For example, an article in the latest Foreign Affairs discusses the opportunities and risks of geoengineering, and concludes that ‘It is time to take geoengineering out of the closet [...] so that the nations of the world can collectively decide whether to raise the shield if they think the planet needs it.’

While geoengineering may provide hopes for solving the climate change problem, it is unlikely to provide a ‘magic bullet’ solution. Investments into combating climate change should be based on sober cost-effectiveness analysis that ensures most ‘bang for a buck’ for public expenditure. Such a policy would most likely include a mix of mitigation, adaption and possibly geoengineering measures.

New research since the IPCC’s two-year old assessment report has suggested that climate change may be progressing faster than previously thought, casting doubt on the feasibility of the current policy response. This week’s meeting in Copenhagen is a welcome reminder of the magnitude of the challenge.
