ClimaWATCH

This dashboard displays information on the incidence of extreme climate events and climate-related health issues. Users can compare information on the location, timing, and severity of extreme climate events and examine state-level health care use and spending associated with those events, in order to assess which populations are most vulnerable to climate change and estimate climate-related morbidity.

State

Heatwave is defined as two or more consecutive days when daily average apparent temperature(AT) exceeds 90-degree Fahrenheit and the 95th percentile of daily average AT in 1981-2019, whichever is greater. For each county, we calculated the percent change in average heatwave episodes over time by fitting a negative binomial model to estimate the slope of change in the number of heatwave episodes by year (from 1981 to 2019). If the resulting slope did not differ significantly from zero (p>0.05), it was categorized as <=0%.

Percent Minority Minority/Language Index Socioeconomic Index Household Composition/Disability Index Housing/Transportation Index

The social vulnerability measures are based on CDC/ATSDR data from 2018. The four indices, which range from 0 (lowest vulnerability) to 100% (highest vulnerability), are derived from 15 individual social factors. Socially vulnerable populations are those with a high risk of needing resources following a natural disaster or public health crisis.
