Global Climate Connectivity Projections for Terrestrial Vertebrates Under Warming

77.9% of global land area is projected to experience a decline in climate corridor effectiveness with warming exceeding 4°C during 2061–2080. This dataset contains a metric called Functional Effectiveness of Climate Connectivity (FECC), developed by author Zhaoning Wu, which quantifies how climate corridors link suitable habitats for biological communities. It was published on figshare in April 2026.

Use Cases

• Modeling species range shifts by analyzing changes in the FECC metric across global land areas.
• Identifying regions vulnerable to ecological isolation by mapping projected declines in climate connectivity.
• Prioritizing conservation areas by overlaying FECC projections with existing habitat networks.
• Assessing biodiversity loss risk by correlating FECC erosion with species community data.

Strengths

• Projections cover the global land area.
• Analysis focuses on a specific future period (2061–2080).
• Dataset size is 127.4 MB, indicating detailed spatial data.

Limitations

• Underlying species data or specific column definitions are not provided.
• Projections are model-dependent and subject to climate scenario uncertainties.
• Validation against observed species movement data is not described.
