Climate Geo-engineering with 'Carbon Negative' Bioenergy

Climate saviour or climate endgame?

Almuth Ernsting and Deepak Rughani, Updated December 2008

This is a critical analysis of proposals for 'carbon negative' bioenergy, including biochar (agrichar) and bioenergy with carbon capture and storage, as a means of reducing atmospheric carbon dioxide concentrations and mitigating climate change. It includes a wider discussion about the impacts of large-scale bioenergy, and about alternative adequate responses to the current crisis.

Interesting to note. In this review and critique of alternatives to burning fossil fuel, all of which the authors roundly condemn as driven by short sightedness, greed and a psychological addiction to industrial based, hierarchical, power structures: the conclusion is that all we can do to save ourselves is a forced return to a pre-industrial arcadian lifestyle. Which can be translated as : first many of us must die. This is helpful? How?

Its a critique specifically of geo-engineering with bioenergy: solar, wind, tidal and other alternatives are not "condemed". Its helpful (the critique) because it points out further study of the impacts on global warming, food production and biosphere diversity are required. I see a call to reduce our consumption, change our lifestyles beyond reliance on industrial growth. There are a billion people who go hungry on this planet, partly do to the consequences of industrial growth..
A holistic approach as the authors call for, rather than an industrial/profit driven one.
