The Lancet Countdown tracks progress on health and climate change and provides an independent assessment of the health effects of climate change, the implementation of the Paris Agreement and the health implications of these actions. The research evidence thus generated will help to inform decision-making and drive an accelerated policy response to climate change.

The initiative is a collaboration between 24 academic institutions and intergovernmental organizations based in every continent and with representation from a wide range of disciplines including climate scientists, ecologists, economists, social and political scientists, public health professionals and doctors.

The Lancet Countdown’s 2017 report tracks 40 indicators across five areas, arriving at three key conclusions:

  • The human symptoms of climate change are unequivocal and potentially irreversible.
  • The delayed response to climate change over the past 25 years has jeopardised human life and livelihoods.
  • The past 5 years have seen an accelerated response, and in 2017 momentum is building across several sectors.

Among the report’s co-authors are Delia Grace, veterinary epidemiologist and co-leader of the Animal and Human Health program at the International Livestock Research Institute (ILRI), and Paula Dominguez-Salas, postdoctoral researcher in nutrition at the Royal Veterinary College on joint appointment at ILRI.
