The Land: Carbon farmings added benefits
Media response to Lin, Brenda B.; et al. (2013). „‚BEST practice‘ carbon farming that considers more than just the carbon in trees is vital for farmers, landholders, and the community, according to CSIRO research.“
Lin, Brenda B.; et al. (2013): Maximizing the Environmental Benefits of Carbon Farming through Ecosystem Service Delivery
Lin, Brenda B.; Macfadyen, Sarina, et al. (2013): Maximizing the Environmental Benefits of Carbon Farming through Ecosystem Service Delivery. In BioScience 63 (10), pp. 793–803. DOI 10.1525/bio.2013.63.10.6. (pre-publication)
„Conversely, carbon farming, if it is not implemented carefully, can create disbenefits, such as increased land clearing, monoculture plantations replacing diverse remnants, and unintended impacts across national borders.“

American Chemical Society: Artificial lung to remove carbon dioxide — from smokestacks
Reported on a meeting of the American Chemical Society. „The amazingly efficient lungs of birds and the swim bladders of fish have become the inspiration for a new filtering system to remove carbon dioxide from electric power station smokestacks before the main greenhouse gas can billow into the atmosphere and contribute to global climate change.“
NewScientist: Terraforming Earth: Geoengineering megaplan starts now
„For the first time, we can sketch out this future industry – known as geoengineering – and identify where it would operate.“

„In this study experiments are conducted using the University of Victoria Earth system climate model forced with novelfuture scenarios to explore the reversibility of climate warming as a response to a gradual return to pre-industrial radiative forcing.“
the guardian: Why wed be mad to rule out climate engineering
„If climate change continues then all options to lessen its impact, including geoengineering, must be considered as a last resort“
The Weather Network: Five futuristic plans to combat climate change with geo-engineering
Overview newspaper article. „Meteorologists and climate scientists had a lot to say about last week’s report from the Intergovernmental Panel on Climate Change.“
