Benefits, risks, and costs of stratospheric geoengineering

Stratospheric Aerosol Geoengineering

In response to global warming, one suggested geoengineering response involves creating a cloud of particles in the stratosphere to reflect some sunlight and cool Earth. While volcanic eruptions show that stratospheric aerosols cool the planet, the volcano analog also warns against geoengineering because of responses such as ozone depletion, regional hydrologic responses, whitening of the skies,...

Elective hysterectomy. Benefits, risks, and costs.

This study evaluated the effect of hysterectomy or hysterectomy and bilateral salpingo-oophorectomy (hysterectomy and oophorectomy) versus alternative medical management on life expectancy, quality of life, and direct medical costs. Using techniques of decision analysis and available data on sequelae, it was found that gains in life expectancy and quality of life can be expected when women ages...

Distributive Justice, Geoengineering and Risks

It is generally recognised that the potential positive and negative impacts of geoengineering will be distributed unevenly both geographically and temporally. The question of distributive justice in geoengineering thus is one of the major ethical issues associated with geoengineering. Currently, the question of distributive justice in geoengineering is framed in terms of who gets what (potentia...
