As communities face more frequent hazard warnings, we need better systems to avoid ‘emergency fatigue’

When trust in institutions is weak, emergency warnings can become entangled with narratives about government competency and bureaucratic overreach.

NZ’s glaciers have already lost nearly a third of their ice – as more vanishes, landscapes and lives change

Snow and ice loss warms the land surface and air, setting off a feedback loop of further ice loss. This destabilises the landscape, with potentially hazardous impacts.

Weakening or collapse of a major Atlantic current has disrupted NZ’s climate in the past – and could do so again

Earth’s climate system is connected across hemispheres. When the Atlantic Meridional Overturning Circulation weakens and Europe cools, warming in New Zealand and southern mid-latitudes accelerates.

A clock in the rocks: what cosmic rays tell us about Earth’s changing surface and climate

When landslides or glaciers bring rocks to the surface, cosmic rays bombard them, smashing common atoms into rarer forms and acting as a chronometer of the changing Earth.

Frozen in time: old paintings and new photographs reveal some NZ glaciers may soon be extinct

An estimated 13 trillion litres of ice has already been lost from glaciers in New Zealand’s Southern Alps since 1978. Several are now approaching extinction.
