Discussions regarding geoengineering are centred around stakeholders, scientists and academics (dominates the hyperlinks used in posts). Today's post focuses on the significance of other stakeholders from the public, policymakers as well as 'expert-knowledge' in making critical decisions about geoengineering (fig.1).

The past Vostok ice core records demonstrate a correspondence between temperature fluctuations and levels of greenhouse gases (GHGs) in the atmosphere. A sawtooth pattern of temperature ranges (+2 to -9o C), concentrations of CO2 (280 to 190ppm), and methane (0.78 to 0.32ppm) from 160,000-year records.  A consequence of...

Nobel laureate Paul Crutzen 2006, conceptualised geoengineering as an 'escape route' from climate change, particularly, stratospheric aerosol injection. (Fig.1) Fuelling the divide further between  anti- and pro-. This post outlines the benefits and costs of deploying SRM.

Solar Radiation Management (SRM), is another form of geoengineering aiming to manage and reduce incoming solar energy reaching the Earth, to counteract GHG forcing. Models indicate that the climate system reacts quickly to artificially reduced insolation, and therefore SRM is often branded as a last resort against 'dangerous' warming. Fig.1...
