Keeling Scale

The Keeling Scale is a way to measure the concentration of carbon dioxide (CO₂) in the atmosphere over time. Developed by scientist Charles David Keeling, it tracks the amount of CO₂ in parts per million (ppm), showing how it changes daily, seasonally, and across years. The scale helps us understand climate trends, highlighting the rise in atmospheric CO₂ due to human activities like burning fossil fuels. It’s a vital tool for scientists studying climate change, providing clear, precise data to monitor how our emissions impact the planet.
