What happens to carbon dioxide after we emit it? Half is absorbed within a year or two by plants and the oceans, the rest, in effect, stays in the atmosphere. So, does that mean we have to halve emissions to stop concentrations rising? Unfortunately, no.Despite the vast reserves of carbon dissolved in the oceans, carbon dioxide released by burning fossil fuels does not get diluted away, but makes an indelible mark on climate for hundreds of thousands of years.A lecture by Myles Allen recorded on 7 March 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/carbon-zeroGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

Not all broken records are worth celebrating. Ralph Keeling, a geochemistry professor at UC San Diego, knows this well as the man who oversees an ever-rising measure of the amount of carbon dioxide in our atmosphere.

For thousands of years, the level of CO2 in the atmosphere fluctuated relatively consistently (air bubbles trapped in Antarctic ice provide a record of the past). But, since around the 19th century, CO2 levels have been rising and haven’t really stopped. We know this partly because of the work of Charles Keeling. Keeling developed the first technique for accurately measuring CO2 in the air. He set-up a continuous measurement of CO2 on a volcano in Hawaii in 1958. When you plot out the data collected over years of CO2 observations, you can see a steady upward curve. It became known as the “Keeling Curve” and was an easy-to-understand piece of evidence for global warming. Ralph Keeling, Charles’ son, has now taken over his father’s work and serves as the Principal Investigator for the Atmospheric Oxygen Research Group at the Scripps Institution of Oceanography in San Diego. He spoke to us on the 60th anniversary of his father’s CO2 measurements.

Less than half of Americans think climate change is caused by humans, but scientists are sure about it. So, how do they know that humans are to blame? We also look into the climate change crystal ball to figure out are we doomed? Is the apocalypse nigh? We speak to Prof. Ralph Keeling, Prof. Chris Field, and Dr. David Pierce to find out.
