| The risk of unintended detrimental effects is inherently high because most geoengineering proposals are planetary in scale. |
|
| He goes on to call geoengineering ' planetary methadone ', with dangerous potential side-effects. |
|
| A controversial report by the National Academy of Sciences in 1992 looked at iron fertilization, among other geoengineering options. |
|
| Some rational people open to geoengineering are worried by the fact that sulfates can't address ocean acidification. |
|
| Our knowledge of climate is not yet sufficiently advanced to undertake real planetary geoengineering. |
|
| By relying on technological innovation and development, geoengineering would increase the role of private actors relative to that of government. |
|
| The big environmental NGOs such as Greenpeace, Friends of the Earth or WWF do not try to glamorise or otherwise promote geoengineering. |
|
| The wholehearted public embrace of geoengineering advocated by Benford, Michaelson and others in the nineties has not happened. |
|
| Nevertheless, in the mid-nineties, valiant attempts were made to give geoengineering a good name. |
|
| One reason for the successful conspiracy of silence may well be the still unresolved status of geoengineering under international law. |
|
| It surprises me that economists do not give more credence to the idea of unintended consequences of geoengineering. |
|
| Their silence, to look at its positive aspect, possibly reflects a refusal to be associated with the task of making geoengineering look respectable. |
|
| This is an area where I think geoengineering has to be part of the debate. |
|
| In his most recent survey, he had thrown in a few questions about geoengineering. |
|
| None of this was news to anyone who had spent any time thinking about geoengineering. |
|
| After all, if geoengineering ever gets taken seriously, it's going to be the mother of all engineering projects. |
|
| When you think of geoengineering as interfering in a spontaneously organized and self-regulating system, it sounds a lot like interfering in a free market. |
|
| For one thing, geoengineering may be a scary idea, but the dangers were nowhere near as immediate as the unintentional release of genetically modified organisms. |
|
| Prof Stephen Gardiner, of the University of Washington, Seattle, told the Guardian that so-called geoengineering risked making problems worse for future generations. |
|
| At a meeting to launch the report at the Royal Society today, the government's chief scientific adviser John Beddington said the government should be thinking about a modest investment in geoengineering research. |
|
|
|
| He said that it was time to engage with the ethical and moral questions now that major scientific institutions and a growing group of researchers were starting to consider geoengineering. |
|
| But when it comes to geoengineering, one of my biggest worries is that we might pick geoengineering as an intervention that replicates that pattern. |
|
| Edenhofer explained the meeting would discuss the scientific basis of geoengineering, its impacts and response options, and identify key knowledge gaps at the meeting. |
|
| The viability of ocean fertilization as a geoengineering strategy, and the expected magnitude of the ecological consequences, depends on assumptions about the evolution of community structure in response to fertilization. |
|
| India stressed coherence in the treatment of geoengineering and a balanced geographical representation with regards to developed and developing countries. |
|
| Ocean fertilization represents one geoengineering approach undertaken by humans with the principal intention of stimulating primary productivity in the oceans. |
|
| It was felt that a geoengineering research programme could address the technological and scientific challenges of geoengineering and ensure that legitimate scientific research in this controversial area may proceed. |
|
| Ocean fertilization has been proposed as a geoengineering method that in some regions of the world ocean may enhance ocean uptake of carbon dioxide from the atmosphere. |
|
| As synthetic biology replaces biotechnology in transforming living materials, consortia will propose enormous geoengineering schemes to deflect heat and sequester greenhouse gases. |
