Twitter sentiment data provides another tool for researchers and policy makers to assess these attitudes in order to take more meaningful action on climate change.

Public health researchers found links between HIV tweets and HIV incidence, allowing them to measure sentiment at the local level and assess the overall health of people in the community.

The location of a series of tweets can be determined, allowing researchers to associate information within the tweets with time and place.
