Future projections for a changing climate

MassDOT recognizes the potential threats posed by climate change to the resiliency of the state transportation infrastructure over the coming decades and beyond. Preparing our transportation assets to adapt to future climate-related hazards will help prevent infrastructure failure, improve system reliability, reduce operations and maintenance costs, enhance safety, and protect investments.

 

Downscaled climate projections for Massachusetts are generated as part of the deliverables of the MassDOT climate adaptation vulnerability assessment study  These climate projections at the local scale may be of interest to other state, regional and local organizations who are interested in climate resilience since such information is critical when assessing the potential climate impact on local infrastructure and population.

 

This website provides three sets of climate projection maps for four future periods (2030, 2050, 2070 and 2100) and three emission scenarios (Representative Concentration Pathway 4.5, 6.0, and 8.5):

• Projected percent change in future 24-hour 100-year return interval precipitation;

• Projected future 24-hour 100-year return interval precipitation depth;

• Projected annual maximum number of consecutive days > 95°F

The projections are built upon the outputs of General Circulation Models (GCM) from the Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment for different emission scenarios and future years.  The applicable Coupled Model Intercomparison Project Phase 5 (CMIP5) models are first ranked based on their normalized projection outputs and then three models representing the “low”, “median” and “high” (the 10th, 50th and 90th percentile) projections are chosen to reflect the wide range of model outputs for future precipitation and temperature changes.

For more information, please refer to the “technical document” section for a more detailed description on how the downscaled projections are generated.
