Scenario-Based Projected Changes Map

Created: 2/05/2015 - Updated: 12/13/2018

Overview

EPA's Climate Resilience Evaluation and Awareness Tool (CREAT) Climate Scenarios Projection Map. This map provides easy-to-access scenario-based climate change projections drawn from CREAT. The impacts from a changing climate, including extreme heat and more intense storms, present challenges to water, wastewater, and stormwater utilities and the communities they serve. Understanding how climate change may affect a utility's ability to maintain and deliver adequate, reliable, and sustainable water supplies and clean water services is the first step in climate-related planning.

All climate models project warming, although the extent of warming and the direction of changes in precipitation both vary. This uncertainty is captured as scenarios in the following tabs based on the distribution of model results at each location analyzed (1/2-degree grid for the United States). These scenario data can support your assessments and subsequent decisions across a range of temperature increases and precipitation changes.

Click on each tab to explore different scenarios for specific climate conditions and consider which ones you would wish to learn more about using the Resources tab. The last tab contains technical details on the definition of scenarios and the selection of models for use from published model databases.

This map provides easy to access scenarios of projected changes from EPA's Climate Resilience Evaluation and Awareness Tool for:

  • Annual total precipitation,
  • Annual average temperature,
  • Precipitation intensity for the 100-year storm, and
  • Sea-level rise. 

Audience

Natural resource managers, water ultilities

Climate change impacts pose challenges to drinking water, wastewater, and stormwater (water sector) utilities in fulfilling their public health and environmental missions. Extreme weather events, sea level rise, shifting precipitation and runoff patterns, temperature changes, and resulting changes in water quality and availability contribute to a complex scenario of climate change challenges that have potentially significant implications for the sustainability of the water sector.

The Environmental Protection Agency has ten Regional offices, each of which is responsible for the execution of the Agency's programs within several states and territories.
