The 10km wide Petermann Fjord in northern Greenland. The author’s icebreaker ship is a small dot in the middle. The cliffs on either side are a kilometre high. In the distance is the ‘ice tongue’ of the glacier flowing into the fjord.
Some of the world’s biggest glaciers flow into fjords in Greenland and we need to know what they’ll bump into on the seabed.

At the pilgrimage site of Kedarnath in northern India, disastrous flooding has led many to ask whether the gods are getting angry about human behavior.

Climate change is causing increasingly severe weather – but it’s not just hazards at the Earth’s surface we should be concerned about.
Richard Bates and Alun Hubbard kayak a meltwater stream on Greenland’s Petermann Glacier, towing an ice radar that reveals it’s riddled with fractures.
Glaciologists are discovering new ways surface meltwater alters the internal structure of ice sheets, and raising an alarm that sea level rise could be much more abrupt than current models forecast.
Icebergs in Disko Bay, western Greenland.
Icebergs don’t just pose a risk to ships – they have a profound impact on the natural world and human societies.

To fully understand the extent of climate-related dangers the Arctic – and our planet – is facing, we must focus on organisms too small to be seen with the naked eye.
Warming of more than 1℃ risks unsafe and harmful outcomes for humanity.
Temperature rise of more than 1℃ pushes us towards irreversible climate tipping points, yet Earth is 1.2℃ warmer than in pre-industrial times.

Meltwater rivers in the European Alps will change as glaciers melt – threatening animals that are vital for alpine ecosystems with habitat loss.

Seafloor landforms reveal that ice sheets can collapse at 600 metres per day.
Transantarctic Mountains peaks are some of the only parts of the continent not buried beneath ice.

Mountain systems are sensitive to climate change. Loss of snow and ice sets off effects which have wide ranging consequences.
Rocca Calascio is a mountaintop fortress in the province of L'Aquila in Italy. It bears witness to the long relationship between humanity and mountains, and how natural landscapes are also culture ones.
Often thought of as eternal, mountains are vulnerable to climate change and tourism. To protect them, they should be recognised for their cultural values, not just their natural characteristics.
The Aletsch Glacier in Switzerland is the largest in the Alps. A century ago it was several kilometres longer and several hundred metres thicker.

Switzerland’s glaciers just lost 6% of their ice in a single year.
Switzerland’s Great Aletsch Glacier is 23km long and located in the World Heritage site Swiss Alps Jungfrau-Aletsch. It leads the list of glaciers in the European Alps in terms of length and size, yet since the mid-19th century, it has lost more than 25% of its volume.

Rising temperatures and extreme weather pose an existential threat to many UNESCO World Heritage sites, but widespread discussion is needed for meaningful change.
A look into the heart of the glacier.
Researchers from the University of Oslo have drilled to the bottom of the Kongsvegen glacier. Find out why and how they are listening to the destabilisation of Arctic glaciers: The MAMMAMIA project.
The edge of the Thwaites Glacier extends into the Amundsen Sea in western Antarctica.
If and when the Thwaites Glacier melts, it will result in nearly 0.6 metres of sea level rise, but it holds back another three metres of sea level rise lurking within the Antarctic continent. Listen to The Conversation Weekly podcast.

Climate change will increase the frequency of both floods and droughts in Pakistan. To address these challenges, enhancing infrastructure, building dams and educating the public are necessary.

Antarctica’s ice shelves have helped insulate it from dangerous levels of ice loss. But this is changing.
The findings underscore the urgency of limiting global warming to below 1.5℃, to avert the most catastrophic climate harms.
During ice ages, ice sheets like the one in Greenland have covered much of Earth’s surface.

The Earth has had at least five major ice ages, and humans showed up in time for the most recent one. In fact, we’re still in it.
