Climate Action
When Data Speaks: Turning Facts Into Action
May 7, 2025
We’ve all heard of the importance of driving decisions with data, but how does this fit in with environmental action? As humans, we naturally seek information to confirm our observations and guide our choices. A symbol of progress, data shows us the impact of our past choices and guides us on the path toward a sustainable future.
Whether it’s tracking climate change trends, measuring air and water quality, or analyzing the growth of deforestation, data provides the insights needed to drive meaningful action. It helps scientists, policymakers, and communities understand environmental challenges, develop solutions, and measure progress for a healthier planet.
Data vs. Denial
Despite the power of data, environmental action is often hindered by misinformation and denial. Climate change skeptics and industry interests have long used misleading narratives to sow doubt about scientific findings.
However, there’s no denying the data: Human activities such as the burning of fossil fuels cause large amounts of greenhouse gases to be released into the earth’s atmosphere, creating rising global temperatures. Delayed environmental responses due to climate change denial can result in disaster unpreparedness, public health crises, and biodiversity loss.
That is why the ability to transform data into digestible information is vital to the growth of a society. By navigating the complex landscapes of climate data, data journalists turn numbers and trends into stories that people can understand, connect with, and act upon. Their work not only counters misinformation but also builds bridges between science and society, helping communities see the possibilities for change. In a world flooded with noise and uncertainty, data journalism lights the path forward, empowering individuals to make informed choices, advocate for stronger environmental protections, and become active participants in building a resilient future.
Transforming Data into Action
Devastating natural disasters, melting glaciers and polar ice caps, rising sea levels — it’s easy to feel overwhelmed by the sheer scale of environmental data. For many, climate denial isn’t just misinformation; it’s a psychological defense mechanism, a way to cope with anxiety and helplessness triggered by the magnitude of the crisis.
But data doesn’t have to paralyze us. When presented clearly, accessibly, and with purpose, data can become the catalyst for action. Connecting facts to real lives and real communities can move people from fear to empowerment.
Today, data-driven action takes many forms, and grassroots efforts are powerful in environmental data collection. Citizens around the world are documenting environmental changes and contributing valuable information to the scientific community. For example, NASA’s GLOBE Observer is an app that allows volunteers of all ages to observe, collect data, and track changes in their environment, from mosquito habits to tree height to land coverage, providing ground-level information that complements NASA’s satellite data. Community-driven data initiatives like this one help make science more equitable, inclusive, and reflective of real-world conditions.
While these efforts build local power, large institutions advance environmental action on a global scale. Scientific research organizations, universities, and government agencies collect vast amounts of data that help us understand complex systems like ocean currents, atmospheric changes, and biodiversity shifts. NOAA’s climate monitoring programs supply essential data behind major international agreements like the Paris Climate Accord.
Scientific institutions like the National Institutes of Environmental Health Sciences (NIEHS) bridge the gap between environmental data and human health, showing how pollution, climate impacts, and ecosystem changes ripple directly into public health outcomes. Although public health and environmental health are often treated as separate issues, they are deeply intertwined.
Landmark environmental laws, like the Clean Air Act and Clean Water Act, were passed largely because of the overwhelming public health data linking pollution to disease and mortality. Training the next generation of climate leaders, researchers at Columbia University’s Climate School turn complex data models into practical solutions for vulnerable communities facing extreme heat and food insecurity, and other climate-related challenges.
Ready and Action!
The power of data isn’t just in collecting it, it’s what we do with it. Every day, people are transforming concern into action, informing policy, and inspiring local and global solutions. History has shown us that when data speaks, change follows. Every dataset collected, every story told, and every decision made with evidence moves us closer to a sustainable future.
