In the Ice and ClimatE Research at Sheffield (ICERS) group, we study the impact that past, present and future climatic changes have on our ice masses, oceans and atmosphere. This enables us to better understand how they will respond to ongoing global heating, and potential consequences for society.

Research themes

Ice sheet and glacier responses to climate change

Ice sheets and glaciers are sensitive barometers of climate. The current climate crisis has caused many of them to lose mass to the oceans, raising global sea levels. Mountain glaciers also prevent widespread drought to large populations worldwide through seasonal melting. Our research aims to understand how these ice masses operate in response to past, present and future climate changes.

Ongoing projects

BRITICE-CHRONO is a large Natural Environment Research Council Consortium grant, the aim of which is to improve ice sheet forecasting in a warming world. By working out how fast the last ice sheet that covered Britain and Ireland deglaciated, we can test our models of ice sheet flow.

Everdrill: The Everest region glacier drilling programme. Populations in southern and central Asia depend on seasonal glacier ice and snow melt for water supplies, food security and hydroelectric energy production. Using hot-water drilling at Khumbu Glacier, the world's highest glacier in the Everest region of Nepal, the Everdrill team are collecting data which will improve our understanding of how glaciers in this region will respond to climate change.

Water-ice interactions. An ongoing research theme is the interaction between water and ice on, in and under glaciers and ice-sheets. Highlights of our research include: discovering  50+ new subglacial lakes beneath the Greenland Ice Sheet, and that water on the surface of Antarctic Peninsula glaciers can drain through the ice, reaching the bed where it lubricates ice flow.

The atmosphere and oceans in a warming world

The oceans and atmosphere are changing in response to global heating. Our research aims to understand these systems at a global scale. This includes work on North Atlantic Ocean responses to meltwater inputs, the Southern Hemisphere Atmospheric Circulation, and tropical hurricane, monsoon and El Niño variability. 

Ongoing projects

Historical records of past climate. To contextualise current climate changes, it is important to have long term measurements. Instrumental records only go back so far. One rich source of information regarding historical climate conditions are written archives and records. This project aims to reconstruct past climate change using records such as ships logbooks. 

Icebergs as ocean fertilisers. When icebergs are released from an ice sheet, they melt into the ocean surrounding them. This process releases nutrients (eg iron) trapped in the ice into the ocean, and also induces localised convective circulation which brings deeper nutrient-rich waters to the surface where the nutrients can be used to enhance biological productivity. This means that icebergs become feeding grounds for small organisms, such as phytoplankton. This project aims to quantify the impact that icebergs have on ocean ecosystems.

The impacts of the climate crisis

The changing climate is having an impact on our everyday lives. Our research looks at how the ongoing climate crisis is affecting people. Food and water security are a particular concern and form a focus of our research which looks at how global heating will affect crop yields and food webs in fisheries. The climate crisis may also bring more hazards. For example, our research looks to predict how icebergs will be discharged from the ice sheets affecting shipping, and quantify historic rates of flooding in the UK.

Ongoing projects

CODINA aims to increase the understanding of food web dynamics in sub-Arctic ecosystems in order to improve ecosystem management. The project focuses on the diet of Barents Sea cod and how this is linked to variability in the environment and populations of cod and its prey.

Icebergs as hazards to shipping. Collision with an iceberg from the Greenland Ice Sheet caused the Titanic to sink. In recent decades, iceberg numbers have tended to increase, leading to an increased risk to shipping. This project aims to predict the paths and melt rates of icebergs across the shippings routes of the north-west Atlantic. 

Floodstones. Climate change is likely to bring about more frequent coastal flooding. To assess this coastal flood risk, it is important to understand the historical frequency of flooding. Floodstones are horizontal marks often found on the side of buildings or other long lasting structures. This project aims to improve our understanding of coastal flood risk by collating a database of floodstones from around the UK.

The imprint of ice sheets and glaciers on the landscape

Ice sheets and glaciers dramatically alter landscapes; reshapping valleys, depositing hills, cutting away at mountains and moulding bedrock. These processes are ongoing today beneath contemporary ice sheets and glaciers. However, the often kilometer-thick ice obscures our view. To improve our understanding of how glaciers and ice sheets impact on the landscape, our research often turns to the landforms left behind by ice sheets that existed during previous glacial cycles. By studying areas that were formerly occupied by ice sheets (eg Canada, Scandinavia, Britain and Ireland), we can gain better access to the sub-ice environment where many landscapes and landforms were generated.

Ongoing projects

PALGLAC is a large EU-funded grant, the aim of which is to understand Earth’s ice sheets by landform analysis. This will be done by tackling several outstanding questions: How do regularly arranged hills (known as drumlins) beneath ice sheets form? Can we link landform data with numerical models of ice flow? Can machine learning help up map the imprint of ice sheets? How did the last-ice sheet in Scandinavia flow?

Britice. Britain and Ireland were once subsumed by an ice sheet that was over a kilometer thick. This ice sheet left its impact on the landscape around us today. The Britice project brings together mapping of landforms (eg drumlins, cirques, moraines) that were created by the last British-Irish Ice Sheet. This is available to everyone as an interactive map.
