Despite large uncertainties in the fertilization efficiency, natural iron fertilization studies and some of the purposeful iron enrichment studies have demonstrated that Southern Ocean iron fertilization can lead to a significant export of carbon from the sea surface to the ocean interior. From...

Reducing atmospheric carbon concentration by removing past emissions can extend our rapidly diminishing emission budgets corresponding to the target of limiting the temperature increase to 2 °C above preindustrial levels. Forestation measures to offset carbon emissions have already entered...

I investigate the optimal role of carbon sequestration for mitigation in the presence of a ceiling on atmospheric carbon concentration and consider aspects that have so far only been analyzed in the context of a damage function to measure the consequences of climate change for society. I assume...

Staying within the 2° C temperature increase target for climate change requires for ambitious emission reduction targets for the 2012–2020 compliance period. Cost-efficiency is a crucial criterion for the achievement of such targets, requiring analyses of all possible options. Enhancing the...

In diesem Beitrag untersuchen wir die nachhaltige Wohlfahrt der 100 größten kreisfreien deutschen Städte, ausgehend von einem umfassenden Wohlfahrtskonzept, das auch nicht-marktbasierende Größen enthält (Smith et al. 2001; Arrow et al. 2003; Alfsen und Greaker 2007; Dasgupta 2009; Arrow et al. 2010). Die...

To limit global warming to 1.5°C, vast amounts of CO2 will have to be removed from the atmosphere via Carbon Dioxide Removal (CDR). Enhancing the CO2 sequestration of ecosystems will require not just one approach but a portfolio of CDR options, including so-called nature-based approaches...
