Jack Dangermond, president of Esri, said geographic information systems (GIS) and digital mapping can provide the data needed to address climate-change challenges [1].

These tools allow researchers and policymakers to monitor environmental shifts in real time. By visualizing complex data, GIS helps identify which areas are most vulnerable to rising temperatures or sea levels, and where intervention is most urgent.

Dangermond said GIS is a "nervous system" for the planet [1]. This framework enables the coordination of mitigation and adaptation actions by providing a spatial understanding of how different climate-related threats interact across various geographies.

One application of this technology is the mapping of coral-reef networks. Some research suggests that global maps reveal a network of reefs that could survive the climate crisis [2]. These maps help scientists identify potential refugia where coral species might persist despite warming oceans.

However, the effectiveness of these refugia is not guaranteed. Some data indicates that local pollution and fishing are suppressing these climate refugia [3]. This suggests that while GIS can identify safe zones, local human activity can still undermine the resilience of the world's coral reefs [3].

The integration of these mapping tools allows for a more precise approach to conservation. Instead of broad protections, GIS enables targeted efforts to protect the specific reefs that are most likely to survive and seed other areas in the future [2].

By combining global satellite data with local environmental metrics, the technology provides a comprehensive view of planetary health. This approach transforms raw data into actionable intelligence for governments and NGOs working to preserve biodiversity [1].

“GIS can act as a “nervous system” for the planet”

The shift toward GIS-driven climate strategy represents a move from theoretical modeling to spatial precision. While the identification of 'climate refugia' offers a roadmap for conservation, the contradiction between global resilience and local degradation highlights that mapping is only a diagnostic tool; it does not solve the underlying policy failures regarding pollution and overfishing.
