The 2018 Report of the Lancet Countdown

The Lancet Countdown's 2018 report tracks 41 indicators across five key domains in health and climate change, continuously strengthening its methods, data and analysis. It arrives at three key conclusions:

  • IMPACT: Present day changes in heat waves labour capacity, vector-borne disease, and food security provide early warning of compounded and overwhelming impacts expected if temperature continues to rise.

  • DELAY: A lack of progress in reducing emissions and building adaptive capacity threatens both human lives and the viability of the national health systems they depend on, with the potential to disrupt core public health infrastructure and overwhelm health services.

  • OPPORTUNITY: Despite these delays, trends in a number of sectors see the beginning of a low-carbon transition, and it is clear that the nature and scale of the response to climate change will be the determining factor in shaping the health of nations for centuries to come.

The Lancet Countdown is an international, multidisciplinary research collaboration which tracks progress on health and climate change, publishing annually in The Lancet.

It is committed to an iterative and adaptive process, working to further develop and strengthen its indicators over time by employing new methods and making use of new data sources. If you and your academic or intergovernmental institution can support this effort and join the Lancet Countdown.
