Guillas et al. note that this provides an example of how variations in the atmosphere and hydrosphere can drive very small changes in environmental conditions that are able, in turn, to trigger a response from the Earth’s crust. Most importantly, they speculate that, in a warmer world, comparable and larger changes associated with ocean loading…
Dunkley Jones et al. support the view that, while gas-hydrate release was probably not responsible for an initial, rapid, CO2-driven warming, the as yet unknown event responsible for this subsequently triggered the large-scale dissociation of gas hydrates, which contributed to further warming as a positive feedback mechanism. As the authors note, this somewhat equivocal situation…
Climate forcing of geological and geomorphological hazards by Bill McGuire / UCL April 19, 2010: 12 research papers and two summaries of conference discussion sessions contained in this Theme Issue build upon presentations and dialogue at the Third Johnston–Lavis Colloquium held at University College London in September 2009. The meeting brought together delegates from the…

Bill Gates is now the world’s leading financial supporter of geoengineering research. He is an investor in various geoengineering enterprises, including Silver Lining, a company pursuing marine cloud brightening methods. He is an investor in Carbon Engineering Ltd, a start-up company formed by David Keith to develop technology to capture carbon dioxide from ambient air…
However, other atmospheric scientists argue that the complexity of the climate system means that it is impossible to draw any firm conclusions about the consequences of such a radical intervention in the Earth system. They point out, for example, that the chemistry of the atmosphere is complicated, so turning down the amount of sunlight reaching…
Space mirrors & painted roofs Geoengineering may be defined as deliberate, large-scale intervention in the climate system designed to counter global warming or offset some of its effects. More than 40 schemes have been put forward, with some the subject of intensive research. They are usually divided into two types: methods to remove carbon dioxide…
‘The Ultimate Technofix’: Playing God with the Climate – By Clive Hamilton / CAPPE March 7, 2013: Climate scientists have watched with mounting alarm as carbon dioxide concentrations have increased relentlessly. The anxiety has deepened each year as it has become clearer that the range of emissions paths mapped out by experts in the 1990s…
Free Market Solution Climate Change and Free Market SolutionPublished on YouTube May 23, 2013Climate Scientist Hansen Turns Activist, Advocates ‘Fee’ on Carbon Pollution. If you give the money to the public, then it’s not a tax. It’s a fee collected from fossil fuel companies with the money distributed to the public. I would distribute it…
