Technologies to modify the Earth’s climate are at least conceivable and, in the absence of a comprehensive national and international climate change policy, may soon emerge as practical alternatives, a new survey of the subject from the Congressional Research Service suggests.
“The term ‘geoengineering’ describes this array of technologies that aim, through large-scale and deliberate modifications of the Earth’s energy balance, to reduce temperatures and counteract anthropogenic climate change,” the CRS report said. However, “Most of these technologies are at the conceptual and research stages, and their effectiveness at reducing global temperatures has yet to be proven.”
“Moreover, very few studies have been published that document the cost, environmental effects, sociopolitical impacts, and legal implications of geoengineering. If geoengineering technologies were to be deployed, they are expected to have the potential to cause significant transboundary effects.” See “Geoengineering: Governance and Technology Policy” (pdf), August 16, 2010.
The Congressional Research Service — acting at congressional direction — does not permit direct public access to its publications. Some other recent CRS reports obtained by Secrecy News include the following (all pdf).
“The European Union’s Response to the 2007-2009 Financial Crisis,” August 13, 2010.
“Turkey: Politics of Identity and Power,” August 13, 2010.
To empower new voices to start their career in nuclear weapons studies, the Federation of American Scientists launched the New Voices on Nuclear Weapons Fellowship. Here’s what our inaugural cohort accomplished.
Common frameworks for evaluating proposals leave this utility function implicit, often evaluating aspects of risk, uncertainty, and potential value independently and qualitatively.
The FAS Nuclear Notebook is one of the most widely sourced reference materials worldwide for reliable information about the status of nuclear weapons and has been published in the Bulletin of the Atomic Scientists since 1987. The Nuclear Notebook is researched and written by the staff of the Federation of American Scientists’ Nuclear Information Project: Director Hans […]
According to the National Center for Education Statistics’ August 2023 pulse panel, 60% of public schools were utilizing a “community school” or “wraparound services model” at the start of this school year—up from 45% last year.
