On 27 October, we hosted a panel discussion exploring the health impacts of cimate change. This was a hybrid event, held in-person & streamed online. On this page you can find the link to the event recording.

Topic summary

On 6 September 2021, more than 200 health journals across the globe banded together to issue a warning about the ‘catastrophic harm to health’ resulting from climate change. The joint editorial pointed unequivocally to the detrimental effects of higher temperatures and biodiversity loss on human health, such as “tropical infections, adverse mental health outcomes, pregnancy complications, allergies, cardiovascular and pulmonary morbidity and mortality”.

In China, communities are already experiencing the health effects resulting from pollution, overpopulation, urbanisation, extreme weather events and rising temperatures. In addition to the physical health indicators, researchers in China and the UK are discovering increasing implications for mental health – including causal links arising from pollution, weather events, access and use of natural resources and broader ‘eco-anxiety’.

Ahead of the UNCOP26 in Glasgow, the international health community – including the British Medical Journal, the Lancet and the Chinese Science Bulletin – put governments across the globe firmly on notice, stating: “2021 has to be the year the world changes course—our health depends on it”.

COP26 provided a critical platform for countries to map out a coordinated approach to global public health - to share knowledge, resources, and health-tech innovations to respond to global health inequality and limit the impacts of climate change on people’s health and well-being.

In this session, we brought together a panel of world-renowned experts to put in focus the physical and mental health impacts of climate change.
