Posts about Solar Radiation Management
Solar Radiation Management describes a suite of proposed technologies that aim to reflect sunlight back into space before it warms the earth’s climate. These proposed technique would achieve this in one of a number of ways: by spraying sulphur dioxide or hydrogen sulphide into the stratosphere (the upper reaches of the atmosphere), by launching a 300 km2 barrier into heliosynchronous orbit, by making the albedo (reflectivity) of clouds, or by launching billions of reflective balloons into the stratosphere.
By Dr. Rachel Smolker Hydroxyl (OH) is a simple, very short lived but “radical” marriage of one hydrogen and one oxygen molecule. Being “radical” means that it reacts very readily... View Article
[Originally posted by Carnegie Climate Geoengineering Governance Initiative.] by Lili Fuhr All geoengineering approaches are by definition large-scale, intentional, and high-risk. Some have well-known negative impacts, threatening the achievement of the Sustainable... View Article
The prospect of controlling global temperatures raises serious questions of power and justice: Who gets to control the Earth’s thermostat and adjust the climate for their own interests? Who will... View Article
For the past decade, a small but growing group of governments and scientists, the majority from the most powerful and most climate-polluting countries in the world, has been pushing for political consideration of geoengineering, the... View Article
