Climate Health Risks Data Explorer

The Climate Health Risk Data Explorer shows how rising temperatures will affect public health through 10 key health indicators – under two warming scenarios: 

• SSP1-2.6 - A scenario assuming approximately 1.5°C warming, in line with Paris Agreement limits 

• SSP3-7.0 - A scenario in which limited climate action is taken, leading to a 3.6°C rise in average temperatures 

It maps the impact of these changes at three time intervals (2030, 2050, and 2090).

Policy Experts: The Climate Health Risks Data Explorer gives national and international policy experts a tool to help assess the tangible health impacts of climate change. Policymakers can use this data to inform their health system preparedness plans and develop targeted adaptation strategies at a national level.  

Citizens: Citizens can explore the specific risks their country faces — from heatwaves to food insecurity — and make informed choices to protect themselves and their communities. Together, we can use this knowledge to demand better policies, adapt to emerging health threats, and build climate resilience for everyone.  

Healthcare Industry Leaders: Adapting to climate driven changes to global health and healthcare is key to developing resilient healthcare systems. Healthcare industry leaders can use the Climate Health Risks Data Explorer to predict future healthcare needs and develop long term adaption plans. 

NGOs: The Climate Health Risks Data Explorer empowers NGOs  trusted, science-based data to understand how climate change will impact community health where they work. NGOs can use this tool to strengthen local advocacy, design evidence-based campaigns, and hold leaders accountable for urgent climate action. 

Shared Socioeconomic Pathways (SSPs) are tools used to explore how global changes in society, economics, and demographics might shape future climate outcomes. They combine projections of greenhouse gas emissions with different development paths, helping researchers and policymakers understand the challenges and opportunities for climate action. 

One scenario, SSP1-2.6, models a future focused on sustainability and inclusivity. It features strong investment in education, healthcare, and renewable energy, with declining inequality and fewer obstacles to reducing emissions and adapting to climate change. 

In contrast, SSP3-7.0 describes a more divided world, marked by rising nationalism and limited international cooperation. This scenario sees greater inequality and conflict, making it much harder to tackle climate change effectively. 

Indicators  

The indicators presented here were developed following the indicators and models from the Lancet Countdown. These indicators use a variety of approaches and methods but each capture one or more components of the health risks posed by climate change. The indicators do not capture the potential influence of any adaption or behavioural change that might occur in response to these risks.  

Data are presented as relative or absolute change with respect to the baseline (1995-2014), for each of the future time intervals.
