A nine-year record of slush on the Greenland Ice Sheet Abstract. Surface melt on the Greenland Ice Sheet (GrIS) has intensified in recent decades, accelerating GrIS mass loss. Slush (i.e., water-saturated firn or snow) is a key component of this system, y...

The Greenland-Ice-Sheet evolution over the last 24 000 years: insights from model simulations evaluated against ice-extent markers Abstract. Continental ice sheets retain a long-term memory stored in their geometry and thermal properties. In Greenland, this creates a disequilibrium with the present climate, as the ice sheet is st...

Will our mountains lose their snow and ice?

And does it matter if they do?

These questions are answered by BAS glaciologist Dr Hamish Pritchard in a major new UNESCO report for the UN International Year of Glaciers' Preservation.

Mirrors in space and underwater curtains: can technology buy us enough time to save the Arctic ice caps? A conference in Cambridge this week will explore a raft of geoengineering ideas to cool the region down – and attempt to address the fears of those who argue the risks outweigh the benefits

A rather disappointing article in the guardian, presenting a one pretty sided review of geoengingeering solutions to climate change. The scientific community needs to do more to vocally challenge these ideas and promote cutting carbon to combat climate change. www.theguardian.com/environment/...

Can anyone recommend a funding source for a small work package for AntarcticGlaciers focused on celebrating the role of women, indigenous peoples and minoritised people in arctic exploration? I am looking for £3-5k.

Heading back from Nice. Where I donned my weatherman look to present my synthesis of the challenges and milestones for UNESCOs Decade of Cryospheric Sciences.

Warming of +1.5 °C is too high for polar ice sheets - Communications Earth & Environment Warming of +1.5 °C above pre-industrial levels is too high for the Greenland and Antarctic ice sheets, and even the current climate forcing of +1.2 °C is likely to lead to several meters of sea-level ...

Scientists show that +1.5 °C is far too warm for Earth's ice sheets and will result in several metres of sea-level rise over the coming centuries, extensive loss and damage to coastal populations and will challenge the implementation of adaptation measures

A map showing modelled erratic dispersal from Glen Fyne in Scotland. Dispersal flows both east and west aligning with observations of glacial erratics.

New paper presenting the potential sensitivity of erratic dispersals to changes in ice flow direction. We present evidence of a 1 km ice divide shift causing a 180 degree flip in dispersal direction, demonstrating potential as a test of model flow geometry.

Geomorphology signature of ice shelf breakup during British ice sheet collapse in last glacial. What a great set of comb marks they are check out the pics

Change in iceberg calving behavior preceded North Sea ice shelf disintegration during the last deglaciation - Nature Communications Massive tabular icebergs broke off of the UK during the last ice age. The widespread break-up of the ice shelves which produced these giant icebergs can be traced to around 18,000 years ago, and likel...

Icebergs? The size of a city? 90 miles from the UK? Must be a joke, right?

No! Our new paper in @natcomms.nature.com shows massive tabular icebergs broke off the UK in the last ice age before the UK’s ice shelves disintegrated from climate warming.
