Beyond the Ice ·

2025/09/25

Geoengineering is the hot topic in climate science debate - drawing increasingly emotive and divisive responses, as investment in blue-sky engineering proposals grows and progress on decarbonisation stutters. Geoengineering is the deliberate, large scale intervention in Earth's environment and natural systems. As the impacts of climate change start to be felt, preliminary ideas like putting a huge underwater curtain around the unstable Thwaites Glacier are getting more and more media time. Are

2025/07/30

When news broke that Antarctica had gained ice mass between 2021 and 2023, it sparked debate across comment sections worldwide. How could the continent be gaining ice when we're constantly told it's melting? The reality reveals fascinating insights into how Antarctica's ice system responds to extreme weather.Climate scientist Dr Michelle Maclennan from British Antarctic Survey explains how scientists measure ice changes across this enormous continent. What does "mass balance" actually mean? What

2025/06/12

New research suggests there's been a shocking 22% drop in the Emperor penguin population in Antarctica over just 15 years - more than double previous estimates and outpacing even the most pessimistic projections.In this episode, we speak to Dr Peter Fretwell about his findings, and how he uses satellite technology to count Emperor penguin colonies in some of Earth's most remote and inaccessible locations. We explore why these majestic birds are uniquely vulnerable to climate change, with their

2025/05/14

Forty years ago, British Antarctic Survey scientists made a world-changing discovery: a hole in Earth's protective ozone layer above Antarctica. In this episode, meteorologist Jonathan Shanklin recounts how his routine measurements at Halley Research Station revealed data points literally 'falling off the graph' - the first evidence linking chlorofluorocarbons to ozone depletion. Professor John Pyle explains how this evidence led to the Montreal Protocol, now ratified by every country worldwide and

2025/02/27

In February 2025, there was less sea ice on Earth than ever recorded. It's the coldest time of year in the Arctic, and the freeze up of Arctic ice is nearing its maximum - but that maximum is looking small, significantly below the record lows seen in 2012. Polar climate scientist Dr Caroline Holmes explains what's influencing these lows in Arctic sea ice, and how it fits into the global climate.Will the Arctic be 'ice free in summer by 2100'? How do climate scientists actually come up with these

2025/01/16

Wildfires are devastating the city of Los Angeles, fuelled by a perfect storm of dry conditions and intense mountain winds. In this episode of Beyond the Ice, we break down the weather and climate factors behind this ongoing disaster. Climate scientist Dr Ella Gilbert and ice core expert Dr Thomas Bauska explain how our changing climate is making such disasters more frequent and intense, and discuss what needs to be done to adapt to this new reality.We also take a step back to look at what new

2024/12/02

The Arctic is warming four times faster than the rest of the planet. So far, so bad - and scientists are seeing changes there now. Fresh off scientific fieldwork in the Arctic this summer, marine geophysicist Dr Kelly Hogan and marine biogeochemist Professor Kate Hendry reflect on what they saw and studied in this spectacular and important environment.Through the lens of their science projects - KANG-GLAC and SiCLING - they explain what the consequences of a melting Arctic could be, how these

This is your glaciology briefing! The race is on to understand the Thwaites Glacier in West Antarctica, the world's widest glacier which is retreating and changing rapidly. As warming changes this icy place, communities and governments around the world need the best possible answer to the sea level rise question: how much and how fast?Glaciologists Meghan Sharp and Professor Sridhar Anandakrishnan, and oceanographer Dr Pete Davis talk about their epic field work to study Thwaites Glacier, and

It's summer 2022, and an area of East Antarctica is over 38.5°C warmer than it should be. The mercury has risen to a chilly -10°C... but it should be -50°C. It's the most extreme temperature event ever recorded, and we now know this was caused by global warming. The increase in extreme weather events is the erratic, sharp end of climate change. But what happens when extreme weather hits the continent of extremes - Antarctica? Climate scientists Dr Louise Sime and Dr Tom Bracegirdle from British

2023 set new, dramatic temperature records - and Earth’s frozen places are feeling the heat. Picture the problem: it’s August 2023, the depths of Antarctic Winter, and there’s an area of missing Antarctic sea ice bigger than Greenland. Just 8 years ago, the area of Antarctic sea ice was actually growing each year. Then something changed.Climate scientist Dr Ella Gilbert from British Antarctic Survey is here with your briefing on what we know about the record-breaking sea ice lows and their
