Thank you to all who joined CAFE’s State of the Science: AI and Data Science - Beyond the Buzzwords webinar with Dr. Marianthi Anna Kioumourtzoglou from Brown University and Dr. Joan Casey from the University of Washington! If you missed it, or want to review key points, here’s a recap, with links to the relevant moments in the recording.

How Researchers Are Currently Using AI

Dr. Casey outlined practical ways environmental health researchers are engaging with generative AI tools:

• Coding assistance
• Assisting in literature review searches
• Editing text for manuscripts/proposals
• Generating graphs for presentations

The shift to using AI has been dramatic. Stack Exchange, once the go-to resource for coding help, has seen a 75% drop in traffic since 2017 as researchers have begun to turn to AI tools instead.

Concerns

Electricity Consumption: Data centers now consume approximately 4% of U.S. electricity, projected to reach 6.5% - 12.5% by 2028. About 56% of this electricity comes from fossil fuels, and communities near data centers are paying 100 - 200% more for electricity compared to 5 years ago.

Water Consumption: Data centers are water-reliant. Microsoft saw a 34% increase in water consumption from 2022 to 2023, with AI estimated to use more water annually than the country of Denmark by 2027.

Algorithmic Bias: AI that is trained on biased or incomplete data will reproduce and amplify those same inequalities in its results. If some communities are underrepresented in the training data, AI models may produce findings that favor well-represented groups while misrepresenting marginalized populations.

Overconfidence in Wrong Results: AI can generate code that runs and produces results but is methodologically wrong. As Dr. Kioumourtzoglou noted, students may receive statistically wrong answers without recognizing the error, which is a risk for those without strong methodological training.

Key Takeaway

Dr. Kioumourtzoglou and Dr. Casey noted that AI can complement but not replace rigorous epidemiological training. While these tools offer tremendous potential for handling complex environmental health data, researchers must maintain critical thinking and push for regulations addressing AI’s environmental impacts.

Thank you to all who joined CAFE’s State of the Science: Greenspace and Health webinar with Dr. Peter James from UC Davis! If you missed it, or want to review key points, here's a recap, with links to the relevant moments in the recording.

The Growing Evidence Base

Dr. James presented on the expanding body of research that shows measures of greenspace are associated with many health benefits. Several studies have found that people living in the greenest areas experience an approximately 12% lower mortality rate compared to those in the least green areas. A 2019 study of the Danish population found that children who grew up with the lowest levels of green space had up to 55% higher risk of developing a psychiatric disorder. 

New Tools to Measure Types of Greenspace

Much of the literature to date has relied on satellite-based vegetation indices like the Normalized Difference Vegetation Index (NDVI) to assess greenspace. However, NDVI is a marker of vegetation and doesn’t distinguish between different types of greenspace or the quality or accessibility of that space. Dr. James’ team is instead applying novel deep learning algorithms to differentiate between trees, grass, and other vegetation types. This allows their studies to determine the potentially different health impacts of varying mixes of vegetation.

Health Impacts

• Mental Health: Evidence has shown that residential green space exposure is associated with lower levels of depression, anxiety, and stress.
• Healthy Behaviors: Evidence suggests that living in greener neighborhoods is associated with better sleep quality and higher levels of physical activity.
• Chronic Diseases: Higher greenspace exposure has been linked to lower incidence of cardiovascular disease, diabetes, and may be associated with a lower risk of Alzheimer’s disease.
• Birth Outcomes: Consistent evidence suggests a positive relationship between greenspace exposure and birth weight.

Key Takeaways

Dr. James emphasized greenspace represents a crucial component of healthy community design. Current research priorities include developing better measures of actual contact with nature using GPS and wearable sensors, understanding the specific elements in nature that drive health benefits, and exploiting natural experiments such as tree planting interventions in at-risk communities. “We need to make [greenspace] not a perk that only the wealthy can have, but something that we see as a core part of our infrastructure,” Dr. James noted.

For more than 25 years, researchers across disciplines and policymakers worldwide have relied on the NASA Socioeconomic Data and Applications Center (SEDAC) to provide essential open-access population, environmental, and socioeconomic data. The spatial data produced or curated by SEDAC were specifically intended to facilitate integration with gridded Earth science data, in particular data from NASA’s constellation of remote sensing instruments. SEDAC has been managed by the Center for Integrated Earth Science Information (CIESIN) at Columbia University since 1998. 

Today, we are excited to announce a new chapter for this invaluable resource: the transition and expansion of the CIESIN data collection, which will now be hosted as part of CAFE RCC’s Data Collection on the Harvard Dataverse Repository. This transition ensures more sustainable, long-term preservation of data while broadening access for researchers, policymakers, and practitioners across disciplines. 

The Harvard Dataverse is a generalist repository that adheres to the FAIR Principles, is open-source, and enables anyone to both deposit and download data. It is free and open to anyone from any discipline, and anyone can share, archive, cite, access, and explore data. 

What’s Changing and What’s Not?

The complete collection of 300 existing SEDAC datasets are migrating to the Harvard Dataverse repository for wider and more sustainable access. All SEDAC data will be available as a clearly labeled subcollection within the CIESIN collection on Harvard Dataverse. CIESIN is also releasing new data into this CIESIN dataverse collection. For example, the Global Gridded Relative Deprivation Index (GRDI v1.10) and EnvClim grids of urban exposure to climate risks have already come online, and over the coming weeks and months you’ll see other datasets being added to these. 

According to CIESIN director, Dr. Alex de Sherbinin, “The CIESIN collection is of great value to those who are seeking to understand current extreme weather risks, such as extreme heat and sea level rise, among highly exposed populations. It also includes projections of population and urban areas to better characterize future exposure. This makes it a perfect fit for the CAFE collection.”

Here’s a look at some of the datasets available on the CIESIN dataverse subcollection:

• Gridded Population of the World (GPW): Global population distribution by age and sex, this dataset has been the gold standard for environmental exposure analysis, disaster preparedness, and policy modeling since the 1990s. Versions 3 and 4 of this flagship data product are available for download in the SEDAC subcollection of the CIESIN collection on Dataverse, and version 5 is under development for future release on Dataverse.
  

• Air Pollution Metrics: Detailed local air quality data, originally developed by academic partners at Washington University in Saint Louis and Harvard University’s Chan School of Public Health, supports ongoing public health research and monitoring.

• Environmental Performance Index (EPI): Data and reports for every release of the Yale/Columbia EPI from 2006-2024, as well as its predecessor, the Environmental Sustainability Index (ESI).

• Global Urban Points and Polygon Dataset (GUPPD): Records on over 125,000 settlements worldwide, including names and population trends since the 1970s, this dataset supports urban planning and historical research. 

These datasets, among many others, will be complemented by new datasets currently in the development pipeline (including, in some cases, updates to the datasets highlighted above). As datasets are completed, they will be deposited into the CIESIN subcollection on Dataverse.

What to Expect in the New Repository

You’ll notice the new repository looks and works a bit differently than what you might be used to. On NASA Earthdata Search, users can still access SEDAC data through a faceted search on variables, years, and regions. On Harvard Dataverse, under CIESIN’s subcollection within the CAFE collection, users will instead browse file lists and apply basic filters. The data are packaged in formats that make them easily downloadable for analysis.

To help you adjust, we’re developing support materials, including tutorials, FAQs, and guides, to make it easier for you to find and download exactly what you need from the new CIESIN subcollection on Harvard Dataverse. 

Looking Ahead

The transition of CIESIN’s data to the CAFE’s Harvard repository collection marks a significant step forward in the long-term preservation of SEDAC’s socioeconomic and environmental data. These datasets are vital for research on population dynamics, environmental exposures, and health outcomes, offering high-value resources for both scientific and policy applications. 

As we continue this transition, you can expect regular updates and new releases of both legacy and next-generation datasets. We’ll be sharing updates and showcasing data from CIESIN in CAFE’s newsletter, on CAFE’s social channels, and on the CAFE GitHub page.

Thank you to all who joined CAFE’s State of the Science: Droughts and Health webinar with Dr. Jesse Berman from the University of Minnesota! If you missed it, or want to revisit key points, here’s a recap, with links to the relevant moments in the recording.

The Hidden Crisis

Of everyone affected by natural disasters around the world, 35% are affected by droughts, yet this is an area that remains understudied. Dr. Berman noted that, unlike dramatic hurricanes or wildfires, droughts' gradual nature does not capture public attention despite its significant impact. 

Research Challenge

Dr. Berman explained the complexity of studying this topic. Unlike direct exposures like heat or air pollution, droughts affect health indirectly through a series of secondary events, like increased dust, changes in the chemical composition of dust, or loss of economic stability, making it challenging to study.

Health Impacts

• Occupational Stress: Dr. Berman discussed his study of Midwestern farmers, drought conditions exacerbated stress 4x higher than other stressors, such as existing pain.
• Compound effects: Dr. Berman explored the compound effects that droughts can have on populations during heat wave events.
• Specific disease impacts: Dr. Berman covered the different drought conditions that enable diseases like West Nile and Lyme Disease to spread.

Key Takeaways

Unlike acute weather events, drought’s gradual nature allows time for interventions. “We can put policies into place before droughts become severe,” Dr. Berman emphasized. 

Current research priorities include developing standardized metrics, better identifying at-risk populations, and developing early warning systems that help policymakers better prepare their communities for resilience.

Workshop: Assessing hurricane exposure for epidemiological research

This workshop, led by Brooke Anderson from Colorado State University, covered how to assess hurricane wind exposure for epidemiological studies using storm tack data and wind field models. She introduced R packages “hurricaneexposure” and “hurricaneexposuredata”, which allow researchers to estimate local-level exposure to hurricanes. She took a deep dive into analytical methods for assessing hurricane exposure, using wind exposure over time in this example case with the R “hurricaneexposure” package.

In the rapidly evolving field of climate and health, staying current with the latest tools and training is essential for impactful work. To support your efforts to navigate this landscape, we’ve launched the Educational Resource Hub, a comprehensive, crowd-sourced collection of educational resources curated by and for the community.

How It Works

Rather than hosting content directly, the Resource Hub serves as a centralized directory linking to existing educational materials. The platform operates on a community-driven model where users can both access and contribute resources, creating a continuously expanding collection tailored to the needs of climate and health professionals. The collection also hosts educational  material created by the CAFE team. 

The Hub was developed through collaboration between our Data Management and Capacity Building teams, with a focus on accessibility and practical utility.

Available Resource Categories

Resource Types:

• Books and reference texts on climate-health topics
• Code repositories with analysis and visualization tools
• Online courses covering technical and professional skills
• Step-by-step tutorials for data analysis methods
• Recorded webinars and instructional videos

Skill Areas Covered:

• Data analysis, visualization, and statistical methods
• Cloud computing and computational tools
• Geospatial analysis and mapping
• API integration and data access
• Grant writing and professional development
• Science communication and writing

Contributing to the Hub

The Hub's strength lies in its community contributions. If you've found or developed resources that have been particularly useful in your work, consider adding them to the collection.

To submit a resource, use the submission form at the bottom of the Hub's main page. We will review submissions for relevance and appropriateness, though users should evaluate resources based on their own needs and verify attribution requirements.

For those with datasets to share, we recommend using Harvard Dataverse, as the Hub only aggregates links to external content rather than hosting files.

Important Considerations

• The Hub links to external content only; no files are hosted locally.
• Resource quality is not verified by CAFÉ. Users should review individual resource terms and attribution requirements
• The collection expands continuously through community contributions; check back regularly for new materials.
