Developed and developing world responsibilities for historical climate change...
At the United Nations Framework Convention on Climate Change Conference in Cancun, in November 2010, the Heads of State reached an agreement on the aim of limiting the global temperature rise to 2 °C...

The Conference of the Parties (COP) of the Convention on Biological Diversity (CBD) first turned its attention to geoengineering at its ninth meeting in 2008, in the context of ocean fertilization. The
View ArticleStratospheric aerosol particles and solar-radiation management
The deliberate injection of particles into the stratosphere has been suggested as a possible geoengineering scheme to mitigate the global warming aspect of climate change. Injected particles scatter solar
View ArticleOcean-fertilization project off Canada sparks furore
When a chartered fishing boat strewed 100 tonnes of iron sulphate into the ocean off western Canada last July, the goal was to supercharge the marine ecosystem. The iron was meant to fertilize plankton,
View ArticleSooty ships may be geoengineering by accident
Oil-burning ships are fertilising the north Pacific with iron – inadvertently putting a proposed geoengineering idea into practice.
View ArticleAdjustment of the natural ocean carbon cycle to negative emission rates
Carbon dioxide removal (CDR) is the only geoengineering technique that allows negative emissions and the reduction of anthropogenic carbon in the atmosphere. Since the time scales of the global carbon
View ArticleGeo-engineering no quick fix for climate change, warn experts
Geo-engineering schemes like reflecting solar radiation or sucking CO2 out of the sky will not be a feasible way to reduce emissions for the next several decades, a new EU-funded report has warned. The
View ArticleHow effective is albedo modification (solar radiation management...
Albedo modification (AM) is sometimes characterized as a potential means of avoiding climate threshold responses, including large-scale ice sheet mass loss. Previous work has investigated the effects
View ArticleIron fertilisation and century-scale effects of open ocean dissolution of...
Carbon dioxide removal (CDR) approaches are efforts to reduce the atmospheric CO2 concentration. Here we use a marine carbon cycle model to investigate the effects of one CDR technique: the open ocean
