Thus The Guardian today. “Yale researchers find that the two terms, often used interchangeably, generate very different responses,” explains the newspaper. New research found that Americans care more deeply when the term “global warming” is used to describe the major environmental challenge than “climate change,” which leaves them relatively cold. These two terms are used interchangeably, but they generate very different responses. Interestingly, the difference was even more pronounced among Latinos, African-Americans, women, and young people. But scientists often prefer climate change to global warming for technical reasons. That is, global warming may result in colder weather in some locations. One way or another, this is a useful reminder that phrasing matters. Occasionally, it matters a great deal. Which reminds me of the proverbial practice in the Austro-Hungarian army of testing all messages to the troops by having them read first by the most stupid among the soldiers. An exemplary practice, this.
