Reorganised members’ evening
Asriel Wilde, University of Liverpool
Icelandic glacier albedo evolution
My dissertation research focuses on long-term albedo trends for Icelandic glaciers, which (as far as I am aware) produces the first long time series (1984-2024) and high resolution analysis of Icelandic albedo evolution.
Roy McGurn
How we are disturbing the carbon cycle?
The aim of the talk is to take a more holistic approach into how we are disturbing the carbon cycle and a pragmatic view of how population, wealth and technology will eventually recalibrate our relationship with it.
Yani Najman has worked in the Himalaya and Tibet for more than 30 years, in location stretching from Pakistan to the west and Myanmar to the east.

How do mountain belts form? The adventures of a Himalayan geologist.
This talk will focus on how the Himalaya formed, and the impact of its formation on resources and hazards.
The talk will provide an overview of the evolution of the mountain belt, and illustrate aspects of the mountain belt’s formation with snapshots of Yanl’s research.

Ascension Island: volcanology and eruptive history of an active UK Overseas Territory
Ascension Island is a volcanic island situated 90km west of the Mid-Atlantic Ridge – (MAR), where its formation began ~ 6-7 Myr ago. The island exhibits multiple rock types that represent its varied volcanic history, with differences not only in composition, but also in eruptive style– from lava flows and domes to thick pumice and scoria deposits. The origins of the Island and its volcanism are as of yet not fully resolved. The range in rock composition observed on Ascension is atypical for an ocean island. In this talk we will explore the range of volcanic products, and possible reasons for this variation.
