Are you still uncertain about climate change? Go and visit a glacier - if you can find one.

Glaciers don't lie; their size is directly linked to climate; they expand and recede as temperature and snowfall patterns change. Glaciers store fresh water, conveniently releasing it during the warmest months of the year. If water is locked-up in a glacier, then it cannot contribute to sea level rise. Glaciers provide pathways into remote mountains, they are beautiful, they are complex.

Weaving her latest research results from inside crevasses at Haupapa/Tasman Glacier with long-term glacier monitoring in Ka Tiritiri te Moana/Southern Alps, Dr Heather Purdie takes the audience on a journey into the mountains explaining how glaciers work, and why scientists view them as accurate indicators of climate change.
