Supporters of President Joe Biden overestimate the negative effects of climate change compared to the views of prevailing establishment science, a poll of likely voters by Rasmussen has shown.
A majority of the respondents who approved of Biden believed that humankind will “become completely or nearly extinct due to climate change” in the next 100 years if carbon dioxide emissions continue at the same volume as in the past decade.
About two-thirds of those who disapproved of Biden said climate change would lead to extinction in more than 100 years or not at all.
More than two-thirds of Biden supporters estimated that the earth’s surface temperature has warmed more than 3 degrees Fahrenheit since the preindustrial times in the late 1800s.
Establishment estimates, such as from the National Oceanic and Atmospheric Administration, put the figure at slightly over 2 degrees.
People who picked CNN, MSNBC, NBC, ABC, or CBS as their favorite cable or broadcast news source were less likely to pick the answers matching established estimates than those favoring Fox News or “another” network.
The poll was conducted between April 29 and May 3 among 2,000 likely voters. The Heartland Institute is a conservative think tank that holds a position skeptical about the magnitude of negative effects of global warming.
The pollster also asked whether climate change is primarily caused by human activity or by “long-term planetary trends.” More than 80 percent of Biden supporters picked the former option, while nearly as much of those who disapproved of him picked the latter.
The question only allowed either-or answers, leaving some ambiguity in the results. While many scientists say human activity is the primary factor behind the current changes in global temperature, they also believe major shifts in climate occurred in the ancient past. As such, one may believe concurrently that long-term trends have been the primary factor overall, but that the current changes have been affected primarily or in major part by humans.
The Biden administration identified climate change as one of its core agenda points, promising to spend trillions on efforts to cut carbon emissions while combining the issue with proposals for spending on other things such as gender and racial diversity as well as child care and housing subsidies.
