The Critic's Resource on AntiEvolution

NCSE Evolution and Climate Education Update for 2018/04/27

(by NCSE Deputy Director Glenn Branch)

Dear friends of NCSE,

A new report on American public opinion about climate change.


Seven in ten Americans think that global warming is happening, and
almost three in five think that, if it is happening, it is mostly
owing to human activity, but only about one in seven know that nearly
all climate scientists agree that global warming is happening as a
result of human activity. Those were among the key findings of Climate
Change in the American Mind: March 2018.

Presented with a definition of global warming as "the idea that the
world's average temperature has been increasing over the past 150
years, may be increasing more in the future, and that the world's
climate may change as a result" and asked whether they thought that
global warming is happening, 70% of respondents said yes, 14% said no,
and 16% indicated that they didn't know.

Asked about the cause of global warming, on the assumption that it is
happening, 58% of respondents said that it is caused mostly by human
activities, 28% said that it is caused mostly by natural changes in
the environment, 7% opted for "neither because global warming isn't
happening," and 5% volunteered that it was a mix of human activities
and natural causes.

Asked to indicate "what percentage of climate scientists think that
human-caused global warming is happening," only 15% selected a value
between 91% and 100% -- the correct range, as repeated independent
studies have demonstrated. The mean of the values selected by the
respondents was 71% (a new high); the median was 75%.

The study was conducted by the Yale Project on Climate Change
Communication and the George Mason University Center for Climate
Change Communication. The surveys were administered in a web-based
environment from March 7 to March 24, 2018, using an on-line research
panel of 1278 American adults.

According to the report, the sample "includes a representative
cross-section of American adults -- irrespective of whether they have
Internet access, use only a cell phone, etc.  Key demographic
variables were weighted, post survey, to match U.S. Census Bureau
norms." The margin of sampling error was plus or minus 3% at the 95%
confidence level.
