At the COP28 climate talks in Dubai from Nov 30-Dec 12, a first-ever dedicated Health Day has been set aside today on Dec 3.

Synopsis: Every first and third Monday of the month, The Straits Times analyses the beat of the changing environment, from biodiversity conservation to climate change.

From heatwaves and floods triggering illness and death to air pollution from burning fossil fuels killing millions of people a year, climate change really is a global health crisis and requires urgent action to cut greenhouse gas emissions.

Yet for nearly 30 years, the annual UN climate conferences, or COPs, have failed to focus on the escalating human impacts from climate change. Negotiators have focused more on cutting greenhouse gas emissions than on the link to health.

In this episode, ST's climate editor David Fogarty hosts Dr Maria Neira, the World Health Organisation's top public health and environment official, to talk more about the importance of such issues on the COP's first-ever Health Day.

They discuss why it is so urgent that nations take action now to tackle climate change and why doing so could be the ultimate public health opportunity.
