There are numerous unanswered questions regarding climate change and its impact on coastal ecosystems in the United States. Some of the key areas of uncertainty include:
1. **Sea Level Rise Projections**: What are the most accurate predictions for sea-level rise in specific coastal regions over the next few decades, considering factors like glacial melting and thermal expansion of water?
2. **Ecosystem Resilience**: How will different coastal ecosystems (mangroves, salt marshes, coral reefs) respond to varying degrees of climate change, and what thresholds of change (temperature, salinity, etc.) might lead to irreversible damage?
3. **Biodiversity Impacts**: How will climate change affect the distribution and population dynamics of key species within coastal ecosystems, including both flora and fauna? What are the downstream effects on entire food webs?
4. **Habitat Loss and Migration**: What factors will influence the ability of coastal habitats, such as salt marshes and mangroves, to migrate inland as sea levels rise? How will land use changes and urban development impact this migration?
5. **Ocean Acidification Effects**: How will ocean acidification, a direct result of increased CO2 levels, affect calcifying organisms (e.g., corals, shellfish) and what are the implications for coastal food webs and local fisheries?
6. **Storm Intensity and Frequency**: How will climate change affect the intensity and frequency of storms along the U.S. coast, and what will be the implications for coastal infrastructure, ecosystems, and human communities?
7. **Carbon Sequestration Potential**: What is the full potential of coastal ecosystems, such as salt marshes and mangroves, in sequestering carbon, and how might climate change affect their capacity for carbon storage?
8. **Shifts in Fish Populations**: How will changing ocean temperatures and salinity levels affect commercially important fish species’ distribution and breeding grounds, and how will that impact local fishing communities?
9. **Impact on Coastal Water Quality**: How will climate change influence nutrient runoff and harmful algal blooms in coastal waters, and what will be the implications for marine life and human health?
10. **Human-Ecosystem Interactions**: How will changing coastal ecosystems due to climate change affect human communities that rely on these systems for livelihoods, recreation, and cultural practices?
11. **Adaptation and Mitigation Strategies**: What are the most effective strategies for coastal conservation and restoration in the face of climate change, and how can local communities be engaged in these efforts?
12. **Cumulative Effects**: How do multiple stressors (e.g., pollution, invasive species, habitat destruction) interact with climate change to affect coastal ecosystems?
By addressing these questions, researchers can better understand the complexities of climate change impacts and develop effective strategies for conservation and adaptation in coastal regions.
