Scientific countermeasures to combat warming<\/strong><\/em><\/h4>\n

Despite efforts to stabilize CO2 concentrations, it is possible that the climate system could respond abruptly with catastrophic consequences.<\/p>\n

Intentional intervention in the climate system to avoid or ameliorate such consequences has been proposed as one possible response should such a scenario arise.<\/p>\n

In a one-week study, the authors of this report conducted a technical review and evaluation of proposed climate engineering concepts that might serve as a rapid palliative response to such climate emergency scenarios. Because of their potential to induce a prompt (<1 yr) global cooling, this study concentrated on Shortwave Climate Engineering (SWCE) methods for moderately reducing the amount of shortwave solar radiation absorbed by the Earth.<\/p>\n

The study\u2019s main objective was to outline a decade-long agenda of technical research that would maximally reduce the uncertainty surrounding the benefits and risks associated with SWCE. For rigor of technical analysis, the study focused the research agenda on one particular SWCE concept\u2014stratospheric aerosol injection\u2014and in doing so developed several conceptual frameworks and methods valuable for assessing any SWCE proposal.<\/p>\n

 <\/p>\n

Basic physical science considerations, exploratory climate modeling, and the impacts of volcanic aerosols on climate all suggest that SWCE could partially compensate for some effects\u2014particularly net global warming\u2014of increased atmospheric CO2. However, existing data also reveal important limits to the range of CO2 impacts that SWCE could ameliorate; for example, ongoing ocean acidification would not be affected, and some categories of climate emergency scenario might prove unresponsive to SWCE.<\/p>\n

Moreover, significant uncertainty presently surrounds the spatial and temporal response of numerous climate and ecological parameters to SWCE, making the near-term deployment of large-scale SWCE extraordinarily risky.<\/p>\n

, The core questions that need to be addressed can also be clustered into three streams of research:<\/p>\n

Engineering<\/strong>\u2013intervention system development)<\/p>\n

Climate Science<\/strong>\u2013modeling and experimentation to understand and anticipate impacts of the intervention)<\/p>\n

Climate Monitoring<\/strong>\u2013detecting and assessing the actual impacts, both anticipated and unanticipated)<\/p>\n

 <\/p>\n

While a number of studies have suggested the engineering feasibility of specific SWCE proposals, the questions in the Climate Science and Climate Monitoring streams present far greater challenges due to the inherent complexity of temporal and spatial delays and feedbacks within the climate system. Components of any comprehensive research agenda for reducing these uncertainties can be divided into three progressive phases:<\/p>\n
