'Boiling Frog' Effect Makes People Oblivious To Threat of Climate Crisis, Shows Study

An anonymous reader shares a report: Surveys show that the increasing number of extreme climate events, including floods, wildfires and hurricanes, has not raised awareness of the threats posed by climate change. Instead, people change their idea of what they see as normal. This so-called 'boiling frog effect' makes gradual change difficult to spot.

Researchers at Carnegie Mellon University in Pennsylvania wondered if climate change could be made more obvious by presenting it in binary terms. Local newspaper archives describing ice skating on Lake Carnegie when it froze in winter inspired a simple experiment. Some test subjects were shown temperature graphs of a fictional town's winter conditions; others had a chart showing whether or not a fictional lake froze each year. The result, published in Nature, showed those who receiving the second graphic consistently saw climate change as more real and imminent.

Binary data gives a clearer impression of the 'before' and 'after.' The disappearing ice is more vivid and dramatic than a temperature trace, even though the underlying data is the same. 'We are literally showing them the same trend, just in different formats,' says Rachit Dubey, a co-author of the study. These results should help drive more effective ways of communicating the impact of climate change in future by finding simple binary, black-and-white examples of its effects.
