Local Sea Level Projections is a specialized platform by Climate Analytics that provides detailed sea level rise projections for coastal locations worldwide.
This tool offers tide gauge-specific and gridded sea level projections based on comprehensive climate models, helping users understand local coastal impacts under different global warming scenarios.
Key Features
- Location-specific projections for tide gauge stations and gridded locations globally
- Multiple warming scenarios including 2°C, 2.5°C, and 4°C+ pathways (RCP26, RCP45, RCP85)
- Uncertainty quantification with 66% and 90% confidence intervals
- Time series analysis from 2030 to 2200 with decadal projections
- Component breakdown showing contributions from ice sheets, glaciers, and ocean processes
- Expert judgment integration including revised Antarctic ice sheet contributions
Projection Components
- Antarctic ice sheet contributions based on IPCC AR5 and expert elicitation
- Greenland ice sheet dynamics and mass balance projections
- Glaciers and ice caps using improved IPCC AR5 methodologies
- Ocean thermal expansion from CMIP5 climate model simulations
- Ocean dynamics including regional circulation changes
- Land water storage accounting for population and land use changes
- Local processes including land subsidence and gravitational effects
Scenario Framework
- RCP2.6: Staying below 2°C warming with stabilization by 2100
- RCP4.5: Reaching approximately 2.5°C warming by century end
- RCP8.5: Exceeding 4°C warming with continued emissions growth
- Expert revisions: Including Bamber et al. (2019) Antarctic contributions
- Probabilistic approach: Uncertainty ranges from multiple model ensembles
Applications
