Reflections on Dynamism & Our Warming, Peopled Planet
It's been a huge few episodes for stories about our ever-changing Earth system, from living glaciers and volcanic eruptions to our human moments in a warming world. Holly & Anthony take this time to actually understand and reflect on recent conversations with geochemist-volcanologist Dr Lucy McGee and glaciologist Hedda Andersen, sprinkled with some ideas about the growth of Antarctica's ice sheets (see How Antarctica Got its Ice and Antarctic Ice Sheet variability Across the Eocene-Oligocene Boundary Climate Transition), plus some climate change 101 thanks to the IPCC Sixth Assessment Report and Special Report on the Ocean and Cryosphere in a Changing Climate.

Earth's Vanishing Frozen Lands with Glaciologist Hedda Andersen
"Sila can be perceived as the breath of the glaciers, the cold, crisp air that comes from them, and the sense of timelessness they represent... "In todays show, Wonder Podcast crosses to the Arctic and talks to Norwegian glaciologist and expedition guide, Hedda Andersen, who adventures into the fastest warming frozen lands on the planet to research Earth's vanishing glaciers.Trust us— this conversation is special.

South Sandwich Islands (ft. Google Earth & A Little Bit of Productive Stupidity)
In today's show: Holly debuts her rock-omendation, the article on The Importance of Stupidity in Scientific Research. And after exploring why 'ignorance' is good for science and curiosity, Anthony embarks on tectonic travels to the South Sandwich Islands and (with the help of good old Google Earth) we stitch together the fascinating formation of these landscapes, their connection to todays polar ice caps, and we encounter some of the largest seal and penguin populations on the planet ...Find us on Instagram @thegeocoGeoCo connects to you from the traditional country of the Kaurna people of the Adelaide Plains, South Australia.

Tibet's January Earthquake and the Santorini Swarm
Oh, long time no see! In today's episode Holly and Anthony first catch up on their adventures while away from the studio... followed by the GeoGist where we unpack Tibet's devastating January 2025 earthquake and the mysterious earthquake swarm shaking Santorini and nearby Greek islands of the Aegean Sea. We recorded this episode of Wonder in February 2025, one month before another magnitude 7.7 earthquake struck the Myanmar region— resulting in a disastrous loss of life with critical rescue efforts ongoing at the time of publishing. Anthony mentions a scientific paper on Tibet's topographic ooze— find it 2.0.CO;2" target="_blank" rel="ugc noopener noreferrer">linked here. Now we mentioned a GeoCo website, but alas, we're not yet live... it's coming soon!
