Understanding Climatic Change

The year is 1975. The US scientific establishment already knows the planet is warming, and they know why. This landmark report documents what the best minds in atmospheric science understood about climate change nearly fifty years ago - and how little the world listened. Drawing on ice core data, atmospheric measurements, and the earliest climate models, the Committee maps the planet's climatic history and projects its future. They trace the greenhouse effect with precision, connect fossil fuel emissions to rising temperatures, and lay out an urgent research agenda. This isn't speculation - it's the scientific consensus of a generation ago, rendered in careful prose and rigorous data. Understanding Climatic Change reads as both prophecy and period piece. It reveals how early the warning signs were visible, how clearly the science spoke, and how far ahead of public understanding the researchers were. For anyone curious about where climate science began - and how little has changed in the core warnings - this document is essential.
