Revised page title, meta descriptions, and keywords for improved SEO and clarity. Updated section headings, alert labels, and descriptive text throughout to focus on cost comparison and strategic deployment rather than philanthropic framing. Enhanced language for accuracy and consistency in cost-effectiveness analysis of geoengineering approaches.
