I have come here to undertake geological research as part of the joint US-UK International Thwaites Glacier Collaboration, which seeks to determine how the mighty Thwaites Glacier in West Antarctica will contribute to the rate and timing of sea level rise across the globe in the coming decades. This is urgent work – the rate of ice discharge from the glacier has more than doubled over the past 2 decades, and looks set to increase further. Under the right conditions, the glacier also has the potential to enter a runaway retreat phase which could result in catastrophic ice loss because its catchment reaches hundreds of kilometres inland.
This is my seventh time in Antarctica, Continue reading
