Geo-Engineering Unlikely to Work, Conservation Group Says

By Alex Kirby / Climate News Network Nov 3, 2016 Attempts to limit climate change by using the novel technologies known as geo-engineering are very unlikely to work, leading biologists say. Dig deeper ( 4 Min. Read )

Oceans Would Perish Even If Levels of Atmospheric Carbon Were Reduced

Alexander Reed Kelly / Truthdig Aug 6, 2015 While the “future dramatic removal of huge volumes of carbon dioxide from the atmosphere” could restore greenhouse gas concentrations to pre-industrial levels, the world’s oceans would “stay warmer, and more acidic, for thousands of years, and the consequences for marine life could be catastrophic” unless the burning of fossil fuels is stopped, a team of German researchers warns.

Aerosols May Offer Short-Term Lifeline to Corals in Crisis

By Tim Radford, Climate News Network May 30, 2015 Reducing the bleaching of corals by blocking the sun’s rays might buy time to keep tropical reefs alive if efforts are increased to halt global warming. Dig deeper ( 3 Min. Read )

Hope for Carbon Storage Rises Again

By Tim Radford, Climate News Network Apr 20, 2015 American scientists say they are making progress with carbon capture and storage, a process that would help render harmless the chief greenhouse gas. Dig deeper ( 3 Min. Read )

New Ocean Energy Plan Could Worsen Global Warming

By Tim Radford, Climate News Network Apr 5, 2015 An apparently promising way of producing energy from the world’s oceans in fact risks causing catastrophic harm by warming the Earth far more than it can bear, U.S. scientists say. Dig deeper ( 3 Min. Read )

Geoengineering Could Worsen Climate Change

By Tim Radford, Climate News Network Nov 30, 2014 Resorting to geoengineering to tackle climate change would be an admission of failure, UK scientists say. Dig deeper ( 3 Min. Read )

Cutting Emissions Is ‘Perfect Option’

By Tim Radford, Climate News Network Jun 6, 2014 Limiting climate change simply by cutting the use of fossil fuels is a much better option than ambitious bioengineering projects such as trying to limit the effects of the sun, researchers have found. Dig deeper ( 3 Min. Read )

Geo-Engineering ‘Could Mean More Heat’

By Tim Radford, Climate News Network Feb 21, 2014 Using technology to reflect sunlight away from the Earth to reduce global warming could be disastrous, scientists say, because the aftermath could be even more severe heat. Dig deeper ( 3 Min. Read )

Few Would Welcome Geo-Engineering

By Tim Radford, Climate News Network Jan 18, 2014 Research in Australia and New Zealand finds little appetite among the public for trying geo-engineering techniques to prevent global warming. Dig deeper ( 3 Min. Read )

Reducing Sunlight ‘Will Not Cool Earth’

By Tim Radford, Climate News Network Dec 8, 2013 The beguiling idea that global warming can be moderated by engineering the atmosphere has been given a rebuff by two scientists who found the attempt could disrupt rainfall patterns. Dig deeper ( 2 Min. Read )

Putting an Umbrella Over Coral Reefs

By Tim Radford, Climate News Network Aug 12, 2013 The world’s coral reefs are under threat. Some scientists say doses of cloud brightening could solve the problem. Dig deeper ( 3 Min. Read )

Volcano ‘Did Little to Lower CO2′

By Alex Kirby, Climate News Network Mar 22, 2013 Supporters of geo-engineering are disappointed to learn that an Icelandic volcano that threw iron into the nearby ocean did little to reduce long-term atmospheric carbon dioxide levels. Dig deeper ( 3 Min. Read )
