Geoengineering could trigger disaster in parts of Africa

Climate News Network: Less than three weeks after two U.S. researchers called for global agreement on the governance of geoengineering research, British meteorologists have provided a case study in potential geoengineering disaster. Jim Haywood from the Met Office Hadley Center and colleagues report in Nature Climate Change that fine particles concentrated in the stratosphere could precipitate calamitous drought in the Sahel region of Africa. Attempts to tackle climate change by altering the atmosphere may have...

Geoengineering: The necessary answer to climate change
2013-04-03 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Daily Climate: The debate comes down to which response is the most urgent and necessary reaction to climate change. Climate change is reversible and can be solved through mitigation efforts. Adaptation strategies leave families and friends in lesser developed regions to slowly wither away. Mitigation is global and long term while adaptation is local and short term. Mitigation is permanent. Adaptation must be constantly adjusted to address current damage. Examining the scientific consensus about the origins...

Why geoengineering has immediate appeal to China
2013-03-23 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The political dilemma over geoengineering deliberate, large-scale intervention in the climate system designed to counter global warming or offset some of its effects will perhaps be most acute in China. In December, the country listed geoengineering among its Earth science research priorities, in a marked shift in the international climate change landscape noticed by China specialists Kingsley Edney and Jonathan Symons. On the one hand, China's rapid economic growth has seen a huge escalation...

Geoengineering Is a Dangerous Solution to Climate Change
2013-03-22 22:37:00| Climate Ark Climate Change & Global Warming Newsfeed
Huffington Post: As the realities of global climate change become ever more alarming, advocates of technological approaches to "geoengineer" the planet's climate are gaining a following. But the technologies that are promoted -- from spraying sulphate particles into the stratosphere, to dumping iron particles into the ocean, to stimulate carbon absorbing plankton, to burning millions of trees and burying the char in soils -- are all fraught with clear and obvious risks, and are most likely only going to make matters...

Eruption yields bad news for iron fertilization-based geoengineering schemes
2013-03-22 12:47:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: Geoengineering schemes that aim to slow global warming by seeding oceans with iron to boost carbon dioxide-absorbing phytoplankton may not lead to long-term sequestration of the important greenhouse gas, finds a new study published in the journal Geophysical Research Letters. The research looked at the impact of the 2010 eruption of Eyjafjallajökull volcano, which released large amounts of iron in the North Atlantic near Iceland. Some researchers speculated that iron fertilization would lead to...
