Answer:A compelling scientific problem is the challenge of developing effective and scalable carbon capture technologies.Problem Statement:As greenhouse gas emissions, particularly carbon dioxide (CO2), continue to rise, they contribute significantly to global warming and climate change. Despite international efforts to reduce emissions, many industries still release large amounts of CO2 into the atmosphere. Effective carbon capture technologies are needed to mitigate this issue by capturing CO2 directly from industrial processes and the atmosphere, and either storing it or converting it into useful products.Key Aspects:1. Efficiency: Current technologies need to be improved to capture CO2 more efficiently and at a lower cost.2. Scalability: Solutions must be scalable to address emissions from large industrial sources as well as more distributed sources.3. Storage and Utilization: Safe and long-term storage methods are required, or alternatively, technologies to convert captured CO2 into valuable products (e.g., fuels, building materials).Importance:Addressing this problem is crucial for reducing atmospheric CO2 levels and combating climate change, contributing to a sustainable and healthy environment.
