By Shaun Eaves, Andrew Lorrey, Brian Anderson, Heather Purdie and Lauren Vargo of New Zealand ranks third globally in the proportion of ice lost from glaciers. Almost 30 percent of ice volume has melted during the past 24 years and what remains is disappearing at an accelerating pace, according to a recent global assessment. Almost 300 glaciers have now vanished completely from New Zealand's mountains.

New Zealand ranks third globally in the proportion of ice lost from glaciers. Almost 30% of ice volume has melted during the past 24 years and what remains is disappearing at an accelerating pace, according to a recent global assessment. Almost 300 glaciers have now vanished completely from New Zealand’s mountains. As warming temperatures melt glaciers, the ice loss has repercussions for climate and water cycles.

As the austral summer draws to a close, we are preparing to fly over the Southern Alps to survey glaciers. This annual flight supports the longest scientific study of Aotearoa New Zealand's icescapes—and it shows that all of our glaciers have retreated since 1978.

A culmination of over 45 years of research has painted a grave picture for the state of our iconic glaciers. NIWA’s Dr Andrew Lorrey says that hotter temperatures are to blame.  “We’ve had a flurry of harsh summers and repeated marine heatwaves that have caused warm air temperatures to cook our glaciers. As part of our annual snowline survey, we’ve documented ice cover for the Southern Alps since the late 1970s by taking aerial photographs of the snowline position at the end of summer.

As the austral summer draws to a close, we are preparing to fly over the Southern Alps to survey glaciers. This annual flight supports the longest scientific study of Aotearoa New Zealand’s icescapes – and it shows that all of our glaciers have retreated since 1978. This year’s survey comes on the heels of the warmest year on record globally and the second warmest for New Zealand, which produced extreme weather events and impacts that still cut deep for many local communities.
