Tracking Public Beliefs About Anthropogenic Climate Change

Area of Science:

• Environmental science
• Sociology
• Political science

Background:

• Public understanding of climate change is crucial for policy development.
• Previous research indicates varying levels of public acceptance of climate science.
• Understanding demographic and political influences on these beliefs is essential.

Purpose of the Study:

• To analyze public beliefs about anthropogenic climate change in the US from 2010-2015.
• To identify regional variations and changes over time in climate change acceptance.
• To examine the influence of education and political views on public acceptance of climate science.

Main Methods:

• Analysis of over 28,000 interviews from 35 US surveys conducted between 2010 and 2015.
• Examination of nationwide, regional, and state-specific data, including a time series from New Hampshire.
• Statistical analysis of demographic factors, education, political orientation, and responses to climate change questions.

Main Results:

• Over 50% of the US public accepts the scientific consensus on human-caused climate change.
• A significant minority (30-40%) attributes climate change to natural causes, while 10-15% express disbelief or uncertainty.
• Political orientation is the dominant predictor of climate beliefs, overriding education effects for Republicans.

Conclusions:

• Public acceptance of anthropogenic climate change is relatively stable nationwide but shows regional variations.
• While education generally increases acceptance, this effect is moderated by political affiliation.
• Future developments can be tracked against this established baseline of public opinion on climate change.
