Exciting and thought provoking geography talks
David offers a range of exciting geography talks that span human and physical geography. David has spent over 25 years travelling the world studying geography and how it has shaped us and our planet and affected our understanding. He is a geologist who has taught environmental science at university level for many years. He combines this with a passion for communication, and an enthusiasm for exciting audiences about his subject. In his wide ranging and entertaining geographical talks, David broadens horizons and provides thought provoking insights. Click on a talk to find out more.
In 1995 David spent over two months on this island on a wild animal conservation survey. Halfway through, the long dormant volcano decided to awake. The excitement of catching wild animals day and night is overshadowed by the disruption caused by the volcano. David presents an eye witness account of the first, evacuation triggering, eruption and how people coped subsequently. This talk looks not just at the development of a new volcano and its impacts on the environment, but also how it affected local people.
Sixteen years after he witnessed the first eruptions that turned the island upside down, David returned to see how the island has changed. The people are still just as friendly but the airport and the capital are now destroyed and two thirds of the island is now an exclusion zone. This has caused a huge upheaval in life and society and in this talk David shares the insights he gained and compares what he found with what he left. In this talk he looks at the social, environmental, economic and development aspects of relocating the population to the north of the island. and replacing the destroyed infrastructure.

Antarctic environmental science has loomed large in David's professional life. Ozone depletion, climate change and plate tectonics have all given up secrets to scientists studying in one of the harshest environments in the world. Here David explores Antarctica with world class environmental scientists and explores why it is so important to our understanding of the planet and what the future might hold.
In Iceland geological and geographical processes that have shaped the planet are clearly on display. Plate tectonics, geothermal energy, glaciation, natural hazards, impacts and adaptations to natural disaster are all evidenced. The closest wilderness to Europe, abundant volcanism has created an alien planet-like wilderness where no land should be. This volcanic force is still shaping and influencing the country and the talk looks at various examples, and also visits Heimaey the 'Pompeii of the North', which was nearly destroyed in the 1973 eruption.
Using his expertise as a guide to Pompeii, Herculaneum and Vesuvius, David looks at the geography of this volcanically active area and at the eruption history of Vesuvius. The Bay of Naples area is one of the most densely populated, and threatened, areas of Europe. It's crucial tourism industry thrives thanks to the volcanic sites but 600,000 people could be affected by the next eruption. While examining Pompeii and Herculaneum, David uses his knowledge of other volcanic areas to provide wider insights.
David's first visit to Hawaii had him collecting molten lava from a lava lake draining into the sea. On his latest visit, he explores all the volcanic and geological features that make this such a geographically fascinating location. While unique, it also offers insights into wider plate tectonic matters. It also faces vulnerability to other natural hazards, like tsunamis, and impacts and adaptations will be looked at.
David has been an expedition participant on the marine research ship JOIDES Resolution in the Pacific. This is part of an amazing international research program that has helped uncover the secrets of tsunamis, plate tectonics, earthquakes and climate change by drilling through a hole in the bottom of the ship and into the seafloor. Come on board and learn what it's like to conduct scientific research, and support a self-contained floating community for months at a time, in one of the most difficult environments in the world.
Volcanoes have fascinated David since before he went to university to study them. This new talk looks at volcanoes David has visited around the globe and he shares some surprising insights and dramatic photography, and explains why volcanoes are so important, exciting, and relevant to understanding our world.
