A new study finds local weather may play an important role in
Americans’ belief in climate change. The study, published on Monday,
found that Americans’ belief that the earth is warming is related to the
frequency of weather-related events they experience, suggesting that
local changes in their climate influence their acceptance of this
worldwide phenomenon.
“One of the greatest challenges to
communicating scientific findings about climate change is the cognitive
disconnect between local and global events,” said Michael Mann,
associate professor of geography at George Washington University and
co-author of the paper. “It is easy to assume that what you experience
at home must be happening elsewhere.”
The researchers found that
Americans who experience more record highs than lows in temperature are
more likely to believe the earth is warming. Conversely, Americans who
live in areas that have experienced record low temperatures, such as
southern portions of Ohio and the Mississippi River basins, are more
skeptical that the earth is warming.
The study notes that part of
this dichotomy may be because of the early terminology used to describe
climate change that suggested the earth was simply warming – not
changing in innumerable but measurable ways. This might have led
residents living in areas that experienced an unusually cold winter to
doubt that climate change is occurring.
“Who do Americans trust
about climate change; scientists or themselves?” said Robert Kaufmann,
professor in the department of geography and the Center for Energy &
Environmental Studies at Boston University and lead author of the
paper. “For many Americans, the answer seems to be themselves.”
The
researchers also found that a recent period of lower-than-average
temperatures offset the effect of a long warming period, further
supporting their findings that people’s belief in climate change is
local and experiential.
