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...

Recent suggestions to slow down the increase in atmospheric carbon dioxide have included ocean fertilization by addition of the micronutrient iron to Southern Ocean surface waters, where a number of natural and artificial iron fertilization...

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...

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...

Today, most countries have accepted a 2 degrees Celsius temperature increase above preindustrial levels as the maximum tolerable limit for global warming. An exceedance probability of below 20 percent for this limit implies an emission budget of less...

Selecting appropriate indicators is essential to aggregate the information provided by climate model outputs into a manageable set of relevant metrics on which assessments of climate engineering (CE) can be based. From all the variables potentially...

The historical developments are reviewed that have led from a bottom-up responsibility initiative of concerned scientists to the emergence of a nationwide interdisciplinary Priority Program on the assessment of Climate Engineering (CE), funded by the...

To maintain the chance of keeping the average global temperature increase below 2°C and to limit long-term climate change, removing carbon dioxide from

Climate engineering (CE) deployment would alter prevailing relationships between Earth system variables, making indicators and metrics used so far in th

Eine rasche Reduktion der Treibhausgasemissionen ist essentiell, wenn ambitionierter Klimaschutz erreicht werden soll. Bei der Abschätzung der dafür n
