As extreme heat grips many countries and becomes "the new normal", the UN Environment Programme (UNEP) warns of heightened health risks for older persons in the Frontiers 2025 Report published today.

The report dubbed 'The Weight of Time - Facing a new age of challenges for people and ecosystems,' notes that annual heat-related deaths among older persons have risen by an estimated 85 per cent since the 1990s.

There comes a time when communities across China, Japan, India, Europe, the USA and elsewhere face weeks of extreme heat and flooding.

Additional risks arise from deteriorating air quality and floods in low-lying coastal cities where older persons live.
