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>","author":[{"family":"Teckentrup, Lina"}],"container_title":"WARNSIGNAL-KLIMA: Hilft Technik gegen die Erderw\u00e4rmung ?
