Whether you believe the fable about boiling frogs or not, it looks like we’re becoming a world of slowly boiled frogs.

Researchers, led by Frances Moore, professor of environmental science and policy at University of California-Davis, analyzed 2 billion tweets published between March 2014 and November 2016, to determine when people turn to Twitter to talk about the weather. Unsurprisingly, they found that there are far more weather-related tweets during unusual conditions, such as an exceptionally hot day in March or one in September that’s far colder than normal. But, they found that there was significantly less Twitter chatter when historically unusual weather conditions repeated within a few years. If a country experiences exceptionally cold weather for more than five years in a row, these conditions were no longer considered remarkable. And, overall, people’s perceptions of normal weather are based on by experiences from the past two to eight years.

— Humans are “boiling frogs,” slowly getting used to climate-change temperatures

Will we recognise the danger and do something about it, or will we accept our changing environment while we being slowly cooked?
