Climate engineering, or geoengineering, is the deliberate, large-scale alteration of the climate system to counteract climate change caused by accumulating greenhouse gases. One of the main concerns of installing and operating DAC systems at a global scale is what to do with the CO2 after it has been removed from the air. Some of the advantages to DAC systems include their scope, their mobility, and their feasibility with current technology. (IASS). You can be assured our editors closely monitor every feedback sent and will take appropriate actions. Ongoing costs for operation and maintenance of the shield would equal these costs, or even exceed them. Climate engineering remains controversial both because of significant scientific and technological uncertainty and because of the governance challenges and ethical concerns involved in research and any potential deployment. DAC systems are large-scale infrastructure projects requiring design and construction of roads, building facilities, equipment and machinery in order to make these systems a reality. The plant looks like a wall of giant fans that sucks air in through filters which absorb the CO2. Climate engineering, or geoengineering, is the catchall term for these global-scale interventions in Earth’s climate, intended to mitigate or eliminate the effects of global warming. "Climate engineering experts are not talking about this as a substitute for greenhouse gas emission reductions," emphasized Jinnah. Solar geoengineering, also known as solar radiation management (SRM) or albedo modification, is a proposed method for cooling the planet by reflecting a small fraction of incoming sunlight back into space before it can warm the Earth.

As with the other methods discussed, while the intention is to create beneficial changes, there is a high likelihood that a geoengineering solution as significant as a solar shield will cause wide-ranging problems related to extreme weather, droughts and floods, damage to agricultural production, desertification and more—to the point that any beneficial effects are counteracted by worse and more frequent problems. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); The focus of the paper lies on the models underpinning the Intergovernmental Panel on Climate Change (IPCC) Assessment Reports—the first port-of-call for mapping combinations of technologies, alternative pathways of deployment, and climatic impacts. Prominent proposals for implementing solar geoengineering include injecting tiny particles into the upper atmosphere (stratospheric aerosol injection) or brightening the skies over the open ocean (marine cloud brightening or marine sky brightening). Climate Engineering: A Possibility in Today's Age. On Twine, space mirrors, and the joys of making pointless shit, 4400 Massachusetts Ave. NW In addition to more transparent modeling, a lot of careful policy development and governance work is needed to ensure that solar radiation management and carbon dioxide removal technologies play a constructive role in future climate policy. The researchers outline ways in which this trend can be forestalled. Technology has advanced beyond Early’s initial design, but the basic premise remains the same—as does the general level of unfeasibility. But it would be wrong to use them as alternatives to existing climate action plans or instruction manuals. (IASS). The ubiquity of the topic reflects the importance of the issue, and many of the proposed solutions to climate change are technological, ranging from practical to science fictional. The UK’s Stratospheric Particle Injection for Climate Engineering (SPICE) project investigated one example of a method for injecting aerosols particles into the atmosphere using high-altitude balloons. According to their analysis, the poorly substantiated promises delivered by these projections influence research, policy, and industry planning in the near term and may already be entrenching carbon infrastructures. In this instance, the removed CO2 is used as fertilizer in nearby greenhouses, but other options for using the CO2 as fuel are also possible. Since the technology isn’t available at this point, there is a significant and unavoidable delay in any efforts to deploy a solar shade. While some researchers hope that some kind of climate engineering might be a useful addition to the climate policy toolkit, there is a strong consensus that climate engineering is not a suitable replacement for cutting greenhouse gas emissions. Meaningful steps may need to be taken soon to lay a foundation for a decision process regarding research, policy, … Washington, DC 20016, New Scenarios and Models for Climate Engineering, Academic Working Group on Climate Engineering Governance, Climate Engineering Clearinghouse Meeting Report, Civil Society statements on release of NAS “Climate Intervention” reports, Institute for Carbon Removal Law & Policy, Academic Working Group on International Governance of Climate Engineering.
