Suneel Kumar and Ilan Kelman

Good question and response.

Ilan Kelman, I looked with interest at the book that you suggested. I think this is the author but I could not see the book on his RG pages:

https://www.researchgate.net/profile/Paul-Ekins

But managed to look at the chapter list and the very favourable reviewers' comments on the Routledge link. Thank you. This, along with bacterial etc resistance, are my top concerns and have been for quite a time.

But I still love your puffin picture! Just like ours at Bempton.

Thank you for your response, the reference and your puffin!

Mary C R Wilson - Yes, you correctly identified Paul Ekins as the author of the book that I suggested. Glad that it might be useful--and perhaps we could recruit puffins to help us implement the recommendations.

Carbon sequestration is an important technique for reducing climate change because it efficiently removes carbon dioxide (CO2) from the atmosphere and stores it in diverse reservoirs such as forests, soils, and the ocean. This, in turn, serves to decrease the greenhouse effect.

Maintaining Carbon Balance: Natural processes such as photosynthesis in plants and the production of organic matter in soil take CO2 from the atmosphere. Carbon sequestration contributes to a balance between CO2 emissions and removals by improving these processes through afforestation, replanting, and sustainable land management methods, limiting additional CO2 buildup in the atmosphere.

Preserving Biodiversity: Many carbon sequestration initiatives include the restoration or conservation of ecosystems such as forests, wetlands, and grasslands. These initiatives not only trap carbon, but also assist to maintain biodiversity by protecting habitats for a variety of plant and animal species.

Adapting to Climate Change Impacts: Carbon sequestration in ecosystems can help them to be more resilient to climate change. For example, healthy forests can resist extreme weather events such as droughts and floods, which are becoming more often and severe as a result of climate change.

Supporting Sustainable Development: Carbon sequestration programs frequently entail community participation and the adoption of sustainable land management methods. These projects can create economic possibilities, enhance lives, and help to achieve overall sustainable development goals while reducing climate change.

Long-Term Storage: Some kinds of carbon sequestration, such as geological storage of CO2 in subterranean reservoirs, have the ability to store CO2 for thousands to millions of years.

Finally, carbon sequestration process not only mitigate the global warming and climate change, but also protect some important biodiversity which inspires the human being to afforestation and restoration of degraded forest.

As the world grapples with the escalating threat of climate change, innovative solutions are essential to mitigate the increasing levels of atmospheric carbon dioxide (CO2). One promising avenue gaining traction is ocean-based carbon sequestration – a set of techniques that leverage the vastness and potential of the world's oceans to store carbon.Ocean-based carbon sequestration holds promise as a novel and potent tool in the fight against climate change. However, a cautious and collaborative approach is essential to ensure that these techniques are deployed responsibly, considering ecological, technological, and regulatory aspects. With ongoing research and global cooperation, harnessing the power of the oceans could become a pivotal component of a comprehensive strategy to address the challenges of a warming planet.

I think this may not be a feasible solution. The issue may not be at the capture side ( both point sources and direct air capture) but more on what to do with captured CO2. Except for a few locations in the world finding a reservoir to store at least 20 years of storage is a major issue

what we need is technologies that emit less and of course good and tried reduction in energy usage

Carbon sequestration is a key strategy for mitigating climate change by reducing the concentration of carbon dioxide (CO2) in the atmosphere. This process involves capturing CO2 emissions from various sources and storing it in natural or artificial reservoirs, preventing its release into the atmosphere where it contributes to global warming. Here are some important aspects of carbon sequestration as a climate change mitigation strategy:

Natural Carbon Sequestration:

· Forests: Forests act as significant carbon sinks by absorbing CO2 through photosynthesis and storing carbon in biomass, soils, and organic matter. Protecting and restoring forests, as well as sustainable forest management practices, can enhance carbon sequestration.

· Oceans: Oceans absorb CO2 from the atmosphere through physical and biological processes, storing carbon in dissolved form and in marine organisms. However, ocean acidification resulting from increased CO2 absorption is a concern associated with this process.

Soil Carbon Sequestration:

· Practices such as afforestation, reforestation, agroforestry, cover cropping, conservation tillage, and organic farming enhance soil carbon sequestration by increasing the accumulation of organic matter in soils. This helps improve soil health, fertility, and resilience to climate change while reducing atmospheric CO2 levels.

Geological Carbon Sequestration:

· Carbon Capture and Storage (CCS): CCS technologies capture CO2 emissions from industrial sources such as power plants, cement factories, and refineries, and inject them underground for long-term storage in geological formations such as depleted oil and gas reservoirs and deep saline aquifers. CCS can significantly reduce emissions from these high-emission sectors, contributing to climate change mitigation.

Enhanced Weathering:

· Enhanced weathering involves accelerating natural weathering processes, such as the breakdown of silicate rocks, to capture CO2 from the atmosphere and store it in carbonate minerals. This approach has the potential to sequester large amounts of carbon over long time scales and can be applied in various geological settings.

Bioenergy with Carbon Capture and Storage (BECCS):

· BECCS is a combination of bioenergy production from biomass (such as crops and forest residues) and CCS technologies to capture and store CO2 emissions from bioenergy facilities. BECCS can achieve negative emissions by removing more CO2 from the atmosphere than is emitted during bioenergy production, making it a potentially valuable tool for climate change mitigation.

Overall, carbon sequestration plays a crucial role in mitigating climate change by removing CO2 from the atmosphere and storing it in various reservoirs, thereby helping to reduce atmospheric CO2 concentrations and limit global warming. However, it is important to pursue carbon sequestration alongside efforts to reduce emissions at their source and transition to renewable energy sources for a comprehensive approach to addressing climate change.
