Air‐sea carbon dioxide equilibrium: Will it be possible to use seaweeds for carbon removal offsets?

Journal of Phycology, Journal Year: 2023, Volume and Issue: 60(1), P. 4 - 14

Published: Nov. 9, 2023

Abstract To limit global warming below 2°C by 2100, we must drastically reduce greenhouse gas emissions and additionally remove ~100–900 Gt CO 2 from the atmosphere (carbon dioxide removal, CDR) to compensate for unavoidable emissions. Seaweeds (marine macroalgae) naturally grow in coastal regions worldwide where they are crucial primary production carbon cycling. They being considered as a biological method CDR use trading schemes offsets. seaweeds requires verification that seaweed photosynthesis fixes into organic results CDR, along with safe secure storage of removed more than 100 years (sequestration). There is much ongoing research magnitude pools (e.g., living biomass particulate dissolved sediments deep ocean), but these do not equate unless amount result can be quantified verified.

Abstract Background Marine macroalgae (‘seaweeds’) are a diverse and globally distributed group of photosynthetic organisms that together generate considerable primary productivity, provide an array different habitats for other organisms, contribute many important ecosystem functions services. As result continued anthropogenic stress on marine systems, macroalgal species face uncertain future, risking their vital contribution to global productivity service provision. Scope After briefly considering the remarkable taxonomy ecological distribution macroalgae, we review how threats posed by combination anthropogenically induced stressors affect seaweed communities. From there highlight five critical avenues further research explore (long-term monitoring, use functional traits, focus early ontogeny, biotic interactions impact litter coastal vegetation). Conclusions Although parallels with terrestrial vascular plant responses stressors, note impacts some (e.g. habitat loss) much less keenly felt in oceans than land. Nevertheless, common communities, climate change will inevitably be most pernicious threat future persistence species, communities While understanding simultaneous environmental is complex exercise, our attempt synergies priorities elucidate trends mechanisms response, may yet offer small this goal.
