An overview of geoengineering of climate using stratospheric sulphate aerosols

Aug 29, 2008 - We provide an overview of geoengineering by stratospheric sulphate aerosols. The state of understanding about this topic as of early 2008 is reviewed, summarizing the past 30 years of work in the area, highlighting some very recent studies using

A geophysiologist's thoughts on geoengineering

Aug 29, 2008 - The Earth is now recognized as a self-regulating system that includes a reactive biosphere; the system maintains a long-term steady-state climate and surface chemical composition favourable for life. We are perturbing the steady state by changing

Ocean acidification in a geoengineering context

Sep 13, 2012 - Fundamental changes to marine chemistry are occurring because of increasing carbon dioxide (CO2) in the atmosphere. Ocean acidity (H+ concentration) and bicarbonate ion concentrations are increasing, whereas carbonate ion concentrations are

Governing solar geoengineering research as it leaves the laboratory

Dec 28, 2014 - One of the greatest controversies in geoengineering policy concerns the next stages of solar radiation management research, and when and how it leaves the laboratory. Citing numerous risks and concerns, a range of prominent commentators have called

Peatland geoengineering: an alternative approach to terrestrial carbon sequestration

Sep 13, 2012 - Terrestrial and oceanic ecosystems contribute almost equally to the sequestration of ca 50 per cent of anthropogenic CO2 emissions, and already play a role in minimizing our impact on Earth’s climate. On land, the majority of the sequestered

Lifting options for stratospheric aerosol geoengineering: advantages of tethered balloon systems

Sep 13, 2012 - The Royal Society report ‘Geoengineering the Climate’ identified solar radiation management using albedo-enhancing aerosols injected into the stratosphere as the most affordable and effective option for geoengineering, but did not consider in

Field experiments on solar geoengineering: report of a workshop exploring a representative research portfolio

Dec 28, 2014 - We summarize a portfolio of possible field experiments on solar radiation management (SRM) and related technologies. The portfolio is intended to support analysis of potential field research related to SRM including discussions about the overall

Cooling the world with crops

Dr Joy Singarayer, speaking at the Royal Society's Discussion Meeting: Geoengineering - taking control of our planet's climate. ... Planting reflective crops that would send a small percentage of the sun’s light and heat back into space is one
