How much carbon dioxide can be sequestered through different methods ?
The amount of carbon dioxide that can be sequestered varies significantly depending on the method and site conditions. Different methods include geological storage, ocean storage, and terrestrial storage, each with different potentials and technical requirements for CO2 sequestration. Geological storage is one of the most promising methods for long-term storage of CO2. It involves injecting and storing CO2 deep underground, typically in saline formations, depleted oil and gas reservoirs, and unmineable coal seams. The potential for CO2 storage in these geological structures is influenced by various factors such as the size, depth, and permeability of the formations, as well as the existence of impermeable cap rock to contain the CO2. Deep saline formations are porous and permeable rocks filled with saltwater that can store CO2 in various forms such as free gas, dissolved in brine, or mineralized after reacting with the host rock. Depleted oil and gas reservoirs offer another option for CO2 storage. After hydrocarbon extraction, these fields have remaining pore space that can be used to inject and store CO2. Unlike saline formations, they often have pre-existing infrastructure for drilling and injection, which can reduce the cost of storage. Unmineable coal seams, also known as coal bed methane (CBM) reservoirs, can store CO2 through a process called enhanced coal bed methane recovery. In this process, injecting CO2 into coal seams displaces methane, which can be recovered as a energy source while sequestering the CO2. Ocean storage involves dissolving CO2 in seawater at great depths where it remains isolated from the atmosphere. This method relies on either natural processes like ocean upwellings or engineering techniques such as direct injection or pipeline delivery systems. While the exact storage capacity is difficult to estimate due to complex ocean dynamics, studies suggest that the global ocean could theoretically absorb thousands of gigatons of CO2. Terrestrial storage focuses on enhancing the natural processes by which ecosystems capture and store carbon. This includes reforestation, afforestation, and soil management practices that increase carbon stocks in vegetation and soils. The potential for terrestrial storage is significant but varies widely depending on factors like climate, soil type, and land use practices. Globally, it is estimated that forests alone could potentially sequester hundreds of gigatons of CO2 over several decades.

It involves the capture and storage of carbon dioxide (CO2) from the atmosphere, preventing it from contributing to global warming. This process can be natural or artificial, and it plays a significant role in reducing greenhouse gas emissions. Natural carbon sequestration occurs through processes such as photosynthesis, where plants absorb CO2 from the atmosphere and convert it into organic compounds. This process helps to remove CO2 from the atmosphere and store it in plant tissues, which can eventually become part of the soil when the plants die and decompose. Examples of natural carbon sequestration include forests, oceans, and wetlands. Artificial carbon sequestration involves human intervention to capture and store CO2. This can be done through various methods, including direct air capture, carbon capture and storage (CCS), and enhanced rock weathering. Examples of artificial carbon sequestration include direct air capture technology, CCS systems, and enhanced rock weathering techniques. Carbon sequestration is just one piece of the puzzle when it comes to mitigating climate change. Other strategies include reducing greenhouse gas emissions, increasing energy efficiency, and transitioning to renewable energy sources. Reducing greenhouse gas emissions is essential for slowing down the rate of climate change. This can be achieved through various means, such as using energy-efficient technologies, promoting public transportation, and implementing policies that encourage sustainable practices. Increasing energy efficiency helps to reduce the amount of energy needed to power our homes, businesses, and transportation systems. This can be done by upgrading buildings with better insulation, using more efficient appliances, and improving industrial processes. Transitioning to renewable energy sources, such as solar, wind, and hydroelectric power, is crucial for reducing our dependence on fossil fuels and decreasing greenhouse gas emissions. Governments and individuals can support this transition by investing in renewable energy infrastructure and adopting sustainable practices in their daily lives.

What role does deforestation play in climate change ?
The Role of Deforestation in Climate Change Deforestation contributes to climate change by reducing the Earth's capacity to absorb CO2 and releasing stored carbon back into the atmosphere. This process exacerbates the greenhouse effect, leading to global warming. Key points include: - Loss of Carbon Sinks: Trees act as natural carbon sinks, capturing and storing CO2. When forests are destroyed, these carbon sinks are lost. - Release of Stored Carbon: Deforestation releases the carbon stored in trees back into the atmosphere, increasing atmospheric CO2 levels. - Biodiversity Loss: Forests are home to a vast array of species. Deforestation leads to habitat destruction and loss of biodiversity. - Soil Erosion and Degradation: Trees help maintain soil quality. Without trees, soil can become degraded, reducing its ability to store carbon. - Albedo Effect: Forests have a darker surface than bare ground, meaning they absorb more sunlight and heat. When forests are replaced with lighter-colored surfaces like grasslands or croplands, the albedo (reflectivity) of the land increases. - Feedback Loops: Deforestation can create feedback loops that exacerbate climate change. For example, as temperatures rise due to increased CO2 levels, it becomes harder for some forests to survive, leading to further deforestation and more CO2 emissions. To combat the role of deforestation in climate change, strategies such as reforestation and afforestation, sustainable forestry practices, protection of intact forests, promotion of agroforestry, and public awareness and education can be employed.
