Climate is the main threat
Nothing is as potentially threatening to public health as climate change. It has already directly claimed numerous victims as a result of flooding, fires and extreme heatwaves, but the IPCC report warns this is just a precursor of what is to come. The indirect effects will be even greater because the disease, water and food shortages, poorer sanitation and migration resulting from the deteriorating living conditions, extreme heat, fires and rising sea levels will in themselves constitute major social and health challenges.
The term 'climate refugee' has already been established, and these refugees could stem from different regions for different reasons.

The European Commission describes this clearly in its report Proposed Mission: A Climate Resilient Europe (5): 'The COVID-19 pandemic has taught a lesson about how closely environmental, societal and human health are connected. What we have lived through and still will is a mild foretaste of the shocks that climate change may and will cause in the future.' This holistic approach is also highlighted in the EAT-Lancet report, which perfectly demonstrates the close links between health and food production, nutrition, land use and the climate (6).
Similarly, the Norwegian Environment Agency writes in its note on climate change and health that 'Norway's population is generally in good health, and in terms of health we are relatively well equipped to counteract the effects of climate change. Nevertheless, more precipitation, heatwaves and droughts will have an impact on our health.' (7) The report puts the impact of flooding and landslides on health (death, injuries, blocking of emergency vehicles) at the top of the list, followed by heatwaves, new diseases, reduced food supply, more allergies and poorer air quality, release of toxins from soil and landfills, and a greater need for pesticides.
