On 8 December 2023, our Earth & Environment Research Group joined up with Teesside University’s student-led Environmental Research Society, to host a virtual talk by Durham University’s Professor James Baldini. Professor Baldini’s talk entitled ‘Meltwater, meteors, and volcanoes: the elusive cause of the Younger Dryas Event’ tackled the still hotly debated cause of the Younger Dryas Event (YDE).

Following the Last Glacial Maximum, the Northern Hemisphere was steadily warming until an abrupt return to near glacial conditions around 12,870 years ago. This abrupt cold event is a subject of intense debate with three hotly contested theories: glacial meltwater flooding into the North Atlantic, a meteor impact, and a high-magnitude volcanic eruption.

During the talk, Professor Baldini skilfully navigated through the pros and cons of each potential trigger, providing a balanced perspective, and debunking some common misconceptions about the Younger Dryas Event. Whether you’re a seasoned enthusiast in Earth and environmental sciences or simply curious about our planet’s intriguing history, this talk offers a captivating exploration into not only this, but the many similar events that occurred over the past 80,000 years of Earth’s climate.

The recording of Professor Baldini’s talk is available on our research group Teams site but anyone can catch a similar talk by Professor Baldini on the Northeast Geological Society’s YouTube Channel here https://youtu.be/Gqj0M8DpfoE?si=0IwZKqq7ZJlsdxZA. Don’t miss the chance to unravel the mysteries of the past and gain a deeper understanding of the forces that have shaped our planet.
