Glasgow Skeptics visit Cafe Sci: Antarctica – The Case of the Missing Water
March 4 @ 7:00 pm - 9:00 pmFree
The topic this time: Antarctica – The Case of the Missing Water
When ice sheets grow, global sea level lowers. At the time of the last glacial maximum, about 22,000 years ago, the global sea level was about 132m lower than it is today. But estimates of the volume of ice held in the North American, Greenland, and Eurasian Ice Sheets add up to an ice-equivalent sea-level change of 104m. The missing 28m of sea level rise has previously been attributed to the less well-known Antarctic ice sheet. We now estimate that the Antarctic contribution since the last glacial maximum is closer to 9.9 m. So where is the missing 18.1m of global sea level?
About the Speaker:
Derek Fabel works at the Scottish Universities Environmental Research Centre. He is a geomorphologist (studying Earth surface processes and landforms) and AMS ccientist (measuring the concentration of extremely rare cosmogenic isotopes in minerals and organic materials). As Head of the NERC Cosmogenic Isotope Analysis Facility, he is involved in quantifying the natural processes that shape the surface of the Earth. His research focuses on quantifying the rate of change of ice masses on our planet, and the effect this has on global sea level. He has participated in four Antarctic expeditions, most recently in 2018.
