The story of climate change is often told through numbers. Rising temperatures, increasing atmospheric carbon dioxide, and tightening timelines toward global climate targets dominate headlines. Yet behind these numbers lies a quieter, more complex story of engineering innovation. It is a story about how we might redesign industrial systems to reduce emissions without dismantling the infrastructure that modern life depends on. At the center of this effort is carbon capture, a technology that has shifted from theoretical promise to practical necessity. More
