International Summer School “bio:char crossroads”

Summer School 09. - 16.09.2012

"The multi-talented biochar is one of the world's fastest growing research topics. The 1st International Biochar Summer School “bio:char crossroads” offers excellent young scientists from around the world a valuable means of information exchange and professional development. It will be a highly productive event with good opportunities for networking with senior scientists and peers in the field of biochar. The main topics of the Summer School are: biochar production, feedstock availability, system integration, biochar characterization, and soil effects of biochar."

environmental research web: Lack of detail spoils geoengineering schemes

"Scientists still know too little to use geoengineering as a weapon to fight climate change, said Richard Turco. Having organised one of the first ever geoengineering conferences at the American Geophysical Union in 1991, the UCLA researcher is unimpressed by progress made since."

Pringle, K. J.; Carslaw, K. S.; et al. (2012): A multi-model assessment of the efficacy of sea spray geoengineering

Pringle, K. J.; Carslaw, K. S.; Fan, T.; Mann, G.W; Hill, A.; Stier, P. et al. (2012): A multi-model assessment of the efficacy of sea spray geoengineering. In: Atmos. Chem. Phys. Discuss 12 (3), pp 7125–7166.

"Artificially increasing the albedo of marine clouds by the mechanical emission of sea spray aerosol has been proposed as a geoengineering technique to slow the warming caused by anthropogenic greenhouse gases. A previous global model study found that only modest increases and sometimes even decreases in cloud drop number (CDN) concentrations would result from plausible emission scenarios. Here we extend that work to examine the conditions under which decreases in CDN can occur, and use three independent global models to quantify maximum achievable CDN changes."
