New research finds that we normalize rising temperatures remarkably quickly.
By Tom Jacobs – Climate change is significantly increasing the chances of more unsettling weather in the years to come, including longer and more severe heat waves. But if you’re hoping the strange conditions will inspire people to realize that something profoundly dangerous is occurring—and will prod politicians into acting—new research suggests you’re likely to be disappointed.
An analysis of more than two million Twitter posts finds that people do indeed take note of abnormal temperatures. But it also reports that our definition of “normal” is based on recent history—roughly, the past two to eight years.
These findings suggest that, in less than a decade, climate change-induced conditions cease to seem all that unusual. That lack of historical perspective may make it hard to grasp the enormity of the changes that are already underway, and which promise to accelerate.
“This data provides empirical evidence of the ‘boiling frog’ effect with respect to the human experience of climate change,” writes a research team led by Fran Moore of the University of California–Davis. As with the imaginary amphibian who fails to jump out of a pot of water as the temperature slowly rises, “the negative effects of a gradually changing environment become normalized, so that corrective measures are never adopted.” more>
