New poll analysis indicates majority of Americans support action on climate change

A new statistical analysis of polling data from the last decade undertaken by Professor Jon Krosnick, the Frederic O. Glover Professor in Humanities and Social Sciences at Stanford University and a Senior Fellow at the Stanford Woods Institute for the Environment, provides some startling conclusions regarding the attitude of Americans towards climate change in 2013. The data generally repudiate the view that Republican voters are deniers of climate change. The state level analyses includes all states except Wyoming, North Dakota, Alaska, Hawaii, and the District of Columbia:

  • at least 75% of Americans in every state believe global warming has been happening.
  • more than 50% of residents in every state but four Utah, Nevada, Idaho, Montana) believe the U.S. government should do more to address global warming.
  • more than 60% of Americans in every state believe past global warming has been caused by humans.
  • more than 70% of Americans in every state but one (Idaho) believe global warming will pose a serious problem for the United States.

However, less than 16% of Americans in every state see the issue of global warming as extremely important to them personally.
