CDC's Tracking Network uses data from many sources to track
the effects of climate change. While there are a number of indicators related
to climate change, the Tracking Network currently has data related to extreme
heat and flood vulnerability. Extreme heat data can be used to better evaluate
the number of heat-related events at the national level while allowing for
comparisons across states. These comparisons can help local communities design
interventions and better understand the possible health effects and risks to
specific groups of people. These indicators use data from the past to identify
extreme temperatures, extreme heat days and events, and conditions that make
people vulnerable to heat. They also project future extreme heat events to help
estimate the burden of heat-related illness in the next century.
Flood vulnerability data can be used to estimate the number
of people and housing units at risk of flooding, which can be compared across
states and counties. This information can inform interventions and
communication efforts targeting at-risk populations.
Flood Vulnerability
This indicator provides county-level data on the Federal
Emergency Management Agency (FEMA) designated Special Flood Hazard Area
including a number of square miles within the area, the number of people living
in the area, and the number of housing units within the area. These data can be
used to estimate the number of people and housing units at risk of flooding.
Drought Data
Access complete datasets of county-level drought data from the
Downloadable Datasets page.
Future Projections of
Extreme Heat
This indicator allows you to use modelled county-level data
to look at projections of extreme daytime and nighttime temperatures to better
understand how our climate is changing. These data can be used to understand
trends in heat over time and focus preparedness plans to lessen the health
effects of extreme heat.
Historical Extreme
Heat Days and Events
This indicator allows you to look at temperature, heat
index, and the number of days to define extremely hot days and extreme heat
events using modelled data by the county during May-September of each year.
Heat Vulnerability
Included in this indicator are acts which may increase the
thermal danger to people. These measures include diabetes, cardiovascular
diseases, poorness, breed and age , social isolation, disability, population density,
forest canopy, land use, use of crops cultivate
Temperature
Distribution
This indicator allows you, in May-September of each year, to
display daily temperature and heat indexes with model county info. The Network
offers additional health impacts metrics related to excessive heat including
visits to hospital and hot-stress emergency departments. For more detail, see
the Heat Stress Illness content area.
