The trends identified in the Countdown will not be surprising to anyone who has been working on the human impacts of climate change, but the message is clear. At higher levels of global warming, the costs to society in terms of deaths and human health impacts increase significantly. The authors are therefore explicit that society should avoid 'backsliding' towards less ambitious global warming targets. What is notable is that the authors are also very clear that protecting human health globally under a warming climate means phasing out fossil fuels and supporting the most vulnerable with meaningful financing to adapt to the climate impacts we are already locked into. With COP30 on the horizon, the Countdown report is yet another warning to the leaders of high-emitting nations that delaying substantive climate action will be extremely harmful and costly.
The Lancet Countdown on health and climate change is a major initiative. This is a study that brings together over one hundred authors, covering multiple countries and different areas of expertise. The Countdown report does not undertake new research itself, but analyses trends across data produced by international organisations and synthesises the best available peer-reviewed science on climate change. The aim of doing so is to understand how climate change will impact upon human health globally.”
