All in the family
Charles and Ralph Keeling- two scientists of note when it comes to our awareness of global warming, and more notably the
human impact. The late Charles David Keeling was able to measure the levels of carbon dioxide in the atmosphere over time- known as the Keeling Curve, it showed that fossil fuel burning has steadily increased the levels of carbon dioxide in the atmosphere,adding to the global warming effect. His son Ralph has been measuring the levels of oxygen, conversely seeing a drop in oxygen levels over time. An amazing duo whose studies have helped bring home the message. Go green.
