A small boat in the Illulissat Icefjord is dwarfed by the icebergs that have calved from the floating tongue of Greenland’s largest glacier, Jacobshavn Isbrae.
Sea levels could rise by two metres by 2100, sparking a refugee crisis unlike anything the world has ever seen.

Satellites hundreds of miles overheard are helping scientists to predict drought, track floods and see how climate change is changing access to water resources.
The source of the Yamuna River, one of the major rivers draining the Himalayas.
A new report predicts that one-third of the ice in the Himalayas will melt, even if we contain global warming to 1.5C. So what does that mean for the flood-prone valleys below?
Mean annual air temperature on Everest is –13°C at 7,000 metres elevation, and yet the ice in its highest glacier is only –3.3°C.
Bombarding people with scientific information has little effect. Something else is needed to jolt us out of our current climate trajectory.
Trees have died in Rocky Mountain National Park, Colo., as climate change has intensified bark beetle infestations and drought.
As climate change alters temperature and precipitation patterns across the US, it is having especially severe impacts on national parks. These changes could happen faster than many plants and animals can adapt.
Small aircraft carry scientists high above the Southern Alps to survey glacier changes.
Forty years of continuous end-of-summer snowline monitoring of New Zealand's glaciers brings the issue of human-induced climate change into tight focus.
Meet the first team trying to understand the secrets of Mount Everest's glaciers.
Scientists on Arctic sea ice in the Chukchi Sea, surrounded by melt ponds, July 4, 2010.
Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.
Under the right circumstances, cats’ bodies can behave like liquids.
Ig Nobels reward research that first makes you laugh and then makes you think. Investigating the internet meme of fluid felines fits the bill – and adds to the physics field of rheology.
The crack along the Larsen C ice has grown significantly over the past few weeks.
A huge iceberg is set to break free from Antarctica. While the iceberg isn't hugely concerning, it could herald the breakup of the entire Larsen C ice shelf, which could trigger more sea-level rise.
Best-case scenario, how much are we locked into?
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?

Sea otters had been absent from this Alaskan national park for at least 250 years. By marrying math and statistics, scientists map this animal's successful comeback.

There are ticking time bombs, high up in the mountains.
Some parts of Antarctica’s Totten Glacier are more stable than others.
New mapping shows how Antarctica's huge Totten Glacier has retreated far inland, raising sea levels by more than a metre. Rising temperatures could trigger it to do so again.
Glacier melt is one of the major contributors to global sea level rise.

Global average sea level has risen by about 17 cm between 1900 and 2005, but we didn't know how much of that was due to us, until now.
Glaciers have been a major contributor to sea-level rise.
Could sea levels really rise by several metres this century. Probably not, although this century's greenhouse emissions could potentially set the stage for large rises in centuries to come.
Adélie Penguins struggle to reach their nesting sites if there’s too much ice in the way.
Despite their image as cold-loving creatures, Adélie penguins could be winners from climate change.
Between a rock and a hard place.
Scientists have figured out how microbes may have found food when trapped beneath ice for millions of years.
Piton de la Fournaise or “Peak of the Furnace” on Reunion Island is one of the world’s most active volcanoes, shown erupting in August 2015.
What happens beneath the surface before a volcano erupts? Can we predict when one will blow? And how can typhoons and melting glaciers contribute to big eruptions?
