is plankton the solution to global warming?

Introduction

Plankton, microscopic organisms in aquatic environments, play a crucial role in the Earth's carbon cycle and have been proposed as a potential solution to mitigate global warming. This synthesis examines the current research on the relationship between plankton and global warming, focusing on whether enhancing plankton populations can effectively reduce atmospheric CO2 and combat climate change.

Key Insights

Plankton's Role in Carbon Sequestration:
- Plankton can significantly reduce atmospheric CO2 through CO2 assimilation, which has historically decreased CO2 levels from 95% in the Precambrian Eon to 400 ppm today. Enhancing plankton growth by supplying nutrients like nitrogen and phosphorus can further increase their CO2 absorption capacity .
Positive Feedback Mechanisms:
- Increased atmospheric CO2 leads to ocean warming, which diminishes nutrient resupply to the euphotic zone, reducing plankton productivity and weakening the biological pump. This creates a positive feedback loop that accelerates climate change .
Impact of Warming on Plankton Dynamics:
- Rising temperatures increase the carbon demand of coastal microbial plankton, leading to higher CO2 production through respiration, which could exacerbate global warming. Additionally, warming disrupts the stable coexistence of phytoplankton and zooplankton, reducing total plankton biomass and altering aquatic food webs.
Control Strategies for Mitigation:
- Implementing coastal forestation and enhancing plankton nutrients can improve marine ecosystems, increase fish populations, and reduce global warming. These strategies are more effective when combined.
Plankton as Climate Indicators:
- Plankton serve as indicators of climate change due to their sensitivity to environmental changes. They contribute to climate regulation through their role in the CO2 cycle, cloud formation, and altering seawater reflectivity.

Conclusion

While plankton have the potential to mitigate global warming by absorbing CO2, their effectiveness is influenced by various factors, including nutrient availability and ocean temperature. Enhancing plankton growth through nutrient supply and combining it with other strategies like coastal forestation can help reduce atmospheric CO2 and improve marine ecosystems. However, the positive feedback mechanisms and the impact of warming on plankton dynamics highlight the complexity of relying solely on plankton as a solution to global warming.

Plankton And Climate

Plankton serves both as an indicator of climate change and a contributor to it through its role in the CO sub(2) cycle, cloud formation, and sea water reflectivity.

Rising temperature and marine plankton community dynamics: Is warming bad?

Warming reduces marine plankton biomass and alters species turnover, potentially causing shifts in plankton dynamics and putting pressure on plankton-dependent communities like fish.

Long‐term effects of warming and nutrients on microbes and other plankton in mesocosms

Warming and nutrients together have complex interactions, with warming enhancing the positive effects of nutrients on bacterioplankton and ciliates, while reducing phytoplankton biomass and microbial biomass.

Cascading effects of climate change on plankton community structure

Warming directly impacts the top and bottom of plankton food webs, with indirect effects affecting intermediate trophic groups through altered top-down interactions.
