- Indicator 1.1: Between 2000 and 2016, temperatures rose by 0.9oC where people are living, nearly double the average across the globe.
- Indicator 1.2: Between 2000 and 2016, the number of vulnerable people exposed to heatwave events has increased by around 125 million.
- Indicator 1.3: Global physical labour capacity in populations exposed to temperature change has decreased by around 5.3% between 2000 and 2016.
- Indicator 1.4: Annual weather-related disasters have increased by 46% from 2000 to 2013.
- Indicator 1.5: Development and global health efforts over the last 50 years are at risk of being undermined by climate change.
- Indicator 1.6: Vectorial capacity for the transmission of dengue has increased by 9.4% (Aedes aegypti) and 11.1% (Aedes albopictus) due to climate trends since the 1950s.
- Indicator 1.7: The number of undernourished people in 30 countries vulnerable to climate change and highly dependent on regional food production has increased from 398 million in 1990 to 422 million in 2016.
- Indicator 1.8: Globally, climate change alone has directly forced at least 4,400 to migrate and over 1 billion people may be at risk of migration by the end of the century, without further action.
The 2017 Report of the Lancet Countdown
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 a number of sectors; the direction of travel is set, with clear and unprecedented opportunities for public health.
See our indicators for a more thematic breakdown of the report:
Climate Change Impacts, Exposures and Vulnerability
Climate change undermines the foundations of good health, affecting populations around the world, today. Whether through extremes of weather, the spread of infectious disease, or threats to food and water security, these effects are disproportionately felt by those who are most vulnerable, and people in low- and middle-income countries.
Adaptation Planning and Resilience for Health
Numerous cost-effective solutions exist to adapt to climate change and improve public health resilience. Whilst some progress has been made, there more work and resource is urgently needed.
Mitigation Actions and Health Co-Benefits
Responding to climate change yields immediate and tangible benefits for human health, cleaning up polluted air, ensuring healthier diets, and encouraging physical activity. These interventions result in a healthier population, helping to reduce costs for often over-burdened healthcare systems.
Finance and Economics
Early signs of investment in renewable energy and coal-fired power suggest the beginning of a broader transition maybe underway. Accelerated economic policy and spending is essential to deliver on this promise, and secure the health benefits it offers.
Public and Political Engagement
Implementing the Paris Agreement depends on enhanced engagement from the public and policymakers. Health professionals have an important role to play, ensuring that climate change is understood as an issue that is central to health and wellbeing.

Support the Lancet Countdown
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, contact us here.
