In 2021, anthropogenic emissions of carbon dioxide were estimated at 11.0 GtC yr-1 (Friedlingsstein et al. 2022). In spite of this, to prevent warming beyond 1.5&deg;C, greenhouse gas emissions need to reach net zero by 2050. However, currently all projected scenarios capable of reaching this goal rely on &sbquo;negative emissions&lsquo; (Rogelj et al. 2018). Negative emissions describe carbon dioxide removal methods that enhance the uptake and sequestration of anthropogenic carbon dioxide. This chapter focuses on ocean fertilisation, a specific concept of carbon sequestration where nutrients are added to the ocean surface with the intent to increase algae productivity and sequester newly generated biomass in the deep sea.</p>","headline":"Ozeand\u00fcngung zur CO2-Speicherung durch Mikroalgen","identifier":"http://doi.org/10.25592/uhhfdm.12786","image":"https://zenodo.org/static/img/logos/zenodo-gradient-round.svg","inLanguage":{"@type":"Language","alternateName":"deu","name":"German"},"keywords":["Ocean fertilisation, CO2 storage, microalgae, net zero by 2050, carbon dioxide removal, carbon sequestration"],"license":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Ozeand\u00fcngung zur CO2-Speicherung durch Mikroalgen","sameAs":["http://doi.org/10.25592/warnsignal.klima.climate.engineering.12"],"url":"https://www.fdr.uni-hamburg.de/record/12786","version":"1.
