Extreme Heat Climate Risk Map

The map shows the risk of extreme heat for people in each of Colorado’s census tracts — small geographic regions used for the US census. The index assigns a risk level between 0 and 1, where 0 indicates the lowest risk (lightest color) and 1 indicates the highest (darkest color). This index represents a combination of exposure and social vulnerability to extreme heat. Communities with a higher share of young people, older people, households who earn low incomes, outdoor workers, and people with asthma or heart disease are more likely to be harmed by extreme heat.

We have the power to curb the worst of climate change by taking action on eliminating pollution from our atmosphere and investing in the communities who are exposed to the highest risk. To learn about solutions and actions you can take on these issues visit Impacts and Solutions.

Zoom in to see the extreme heat risk index in your census tract. You can use the search bar in the upper-left-hand corner of the map to type in your city or county. Hover over a census tract to see the components of the index in that area. You can also highlight multiple census tracts by clicking and dragging with your cursor.
