Sea ice is thinning at an alarming rate. Snow is shifting to rain. And humans worldwide are increasingly feeling the impact of what happens in the seemingly distant Arctic.
Each year the global temperature is 1 C above the 1951-80 average temperature, glaciers lose, on average, about 0.8 metres of water equivalent depth.

Policy-makers need the courage to commit to meaningful reductions of greenhouse gas emissions if we want to avoid the widespread loss of mountain glaciers.

Climate change is making ocean levels rise in two ways. It’s a problem that will endure even after the world stabilizes and slashes greenhouse gas pollution.
Constructed ice domes release water during dry periods when rain is blocked by high mountain ranges, stifling essential crop cultivation for rural communities.

Mangroves grow in saltwater along tropical coastlines, but scientists have found them along a river in Mexico’s Yucatan, more than 100 miles from the sea. Climate change explains their shift.
From the high Yukon to the mountains of Central Asia, melting ice exposes fragile ancient artifacts that tell the story of the past – and provide hints about how to respond to a changing climate.

New Zealand’s climate has been changing in line with global trends over the last century, warming by 1.1°C. But unless we curb emissions fast, we can brace for more extreme downpours and droughts.
If emissions continue at their current pace, Antarctica will cross a threshold into runaway sea rise when today’s kids are raising families. Pulling CO2 out of the air later won’t stop the ice loss.
We think of mountains as remote and little affected by human activity. Unfortunately, the negative impacts of what we do has important implications for nature, wildlife and human society.
As the jet stream moves northwards, the UK can expect more storms and flooding in the winter.

Ice Age glaciers can help us track the jet stream 12,000 ago, and by comparing its path today we can see how it’s moving northwards, changing weather patterns and indicating climate change.

The parable of the dragons underlines the need to apprehend glacier disappearance in a transdisciplinary way, to create a dialogue between the physical, ecological and philosophical sciences.
