Do clouds affect melting over Antarctic ice shelves?

Do clouds affect melting over Antarctic ice shelves?

The Antarctic Peninsula is the ‘canary in the coalmine’ of Antarctic climate change. In the last half-century it has warmed faster than most other places on Earth, and considerable change has consequently been observed in the cryosphere, with several ice shelves collapsing in part or in full. Representing this change in models is difficult because …[Read More]

Image of the Week – Greenland’s fjords: critical zones for mixing

One of the most challenging research questions to address in the Arctic is how freshwater discharge from Greenland’s largest glaciers affects the biogeochemistry of the ocean. Just getting close to the calving fronts of these large marine-terminating glaciers is difficult. Fjords, hundreds of kilometers long and full of icebergs which shift with the wind and …[Read More]

Image of the Week – Oh Sheet!

The Antarctic and Greenland ice sheets are major players in future sea level rise. Still, there is a lot about these ice sheets we do not understand. Under the umbrella of the World Climate Research Programme, the international scientific community is coming together to improve ice sheet modelling efforts to better grasp the implications of …[Read More]

Image of the Week – Climbing Everest and highlighting science in the mountains

Dr Melanie Windridge, a physicist and mountaineer, successfully summited Mount Everest earlier this year and has been working on an outreach programme to encourage young people’s interest in science and technology. Read about her summit climb, extreme temperatures, and the science supporting high-altitude mountaineering in our Image of the Week. It’s bigger than it looks! …[Read More]

Image of the Week – The future of Antarctic ice shelves

Climate change will increase ice shelf melting around Antarctica. That’s the not-very-surprising conclusion of a recent modelling study, resulting from a collaboration between Australian and German researchers. Here’s the less intuitive result: much of the projected melting is actually linked to a decrease in sea ice formation. Learn why in our Image of the Week… …[Read More]

Image of the Week – Making waves: assessing supraglacial water storage for debris-covered glaciers

A creeping flux of ice descends Everest, creating the dynamic environment of Khumbu Glacier. Ice and snow tumble, debris slumps, ice cliffs melt, englacial cavities collapse, ponds form and drain, all responding to a variable energy balance. Indeed, Khumbu Glacier is a debris-covered glacier, meaning it features a layer of sediment, rocks and house-sized boulders …[Read More]
