Twitter may improve early heat warning systems
New York
Social media platforms like Twitter can be used to apprise the government as well as to provide assistance to the general public in the case of adverse weather conditions such as extreme heatwaves, researchers say. In the study, the researchers found that an increase in the temperature leads to a rise in the number of weatherrelated tweets by users. This helped the government officials to devise early “heat warning systems” where they communicated with the public on Twitter and took actions such as opening cooling shelters or emergency distress lines that people can call if they have heat-related problems, the researchers said. “If more agencies start to include social media and tap into what people are actually experiencing in real time, they can improve their extreme heat early warning systems,” said Chris Uejio, assistant professor at the Florida State University (FSU). For the study, published in the International Journal of Biometerology, the team surveyed more than three million tweets that addressed six different heat-related themes -- air conditioning, cooling centre, dehydration, electrical outage, energy assistance and heat. Among the valid tweets, the heat theme comprised the largest proportion of tweets at 54.2 per cent, followed by air conditioning (29.9 per cent), electrical outage (7.8 per cent) and dehydration (8 per cent).
