USA Science Teachers’ Grasp of Climate Change Is Found Seriously, How Shall We Say, Lacking
A survey of 1,500 teachers in the United States found that on average they spend just one to two hours on average over the course of an academic year.

Science Teachers’ Grasp of Climate Change Is Found Lacking
Most science teachers in the United States spend some time on climate change in their courses, but their insufficient grasp of the science as well as political factors “may hinder effective teaching,” according to a nationwide survey of the profession.
The survey, described in the current issue of the journal Science, found that teachers spent little time on the topic — just one to two hours on average over an academic year.
“It’s clearly not enough time to really provide students with a good scientific understanding,” said Eric Plutzer, the lead author of the paper and a professor of political science at Pennsylvania State University.
Many teachers also provide misinformation about climate change, the survey found. The evidence that human activity is a major cause of recent climate change is overwhelming, but 30 percent of the 1,500 teachers surveyed said they emphasized that recent global warming “is likely due to natural causes,” while 12 percent said they did not emphasize human causes. Half of that 12 percent said they did not discuss any causes at all.
Close to a third of the teachers also reported conveying messages that are contradictory, emphasizing the scientific consensus on human causation and the idea that many scientists believe the changes have natural causes.
The authors of the paper suggested that those teachers “may wish to teach ‘both sides’ to accommodate values and perspectives that students bring to the classroom.” The survey also found, however, that only 4.4 percent of teachers said that they had faced overt pressure from parents, school administrators or the community to teach about climate change.
Professor Plutzer, who is the academic director of Pennsylvania State’s survey research center, said that he and his colleagues were surprised by the level of ignorance the teachers showed in the survey, especially in describing the current state of scientific consensus on the topic.
The research team, which collaborated on the project with the National Center for Science Education, surveyed 1,500 teachers from high schools and middle schools in all 50 states.
Josh Rosenau, the programs and policy director for the science education center, said that he found it “encouraging” to see how many teachers were spending at least some time on climate change. “Coming into it, we expected the number to be a lot lower than it was,” he said. And while the teachers might not be reporting a great deal of overt pressure, he said, “The broader environment that they are living in is shaping how willing they are to be forthright about the science.”
Bertha Vazquez, a teacher in Miami who incorporates climate change into all her courses, said the pressure was real. “Every year, I get the email from a father who says, ‘This is garbage,’ and why am I teaching this?” she said. The fear of that kind of response might dissuade other teachers, she said, even though climate change is included in Florida’s education standards.
“If you’re not as confident in the subject area, you’re going to avoid it,” Ms. Vazquez said. “It’s no fun to field those phone calls.” An advocate for climate education, Ms. Vazquez has persuaded colleagues, including those teaching German and art, to incorporate climate issues into their courses.
The lack of knowledge of the science is understandable, Professor Plutzer said, because “very few current teachers had much exposure to climate science when they were in college.”
Climate change is still not often part of a formal curriculum, so the instruction in one year rarely can add to the previous year’s work, Professor Plutzer added. And teachers feel pressured to focus more intensely on topics that appear on “high-stakes tests” that define much of today’s educational process, he said.
The evolving nature of climate science means continuing teacher education is essential, said Mr. Rosenau of the science education center.
“If you graduated college in the 1990s and are teaching evolution the way it was taught when you were in school, you’re not doing anything wrong,” he said. “If you’re teaching climate change the way you learned it in the 1990s,” when the role of human activities and burning of fossil fuels was less clear, “you’re kind of teaching climate change denialism.”
Still, climate science has increasingly become part of lesson plans, and is likely to become more prominent.
The Next Generation Science Standards developed several years ago by 26 states, while not providing a specific curriculum, serve as guidelines that describe what students should learn in science classes.
The standards have been adopted by 16 states and the District of Columbia, but have a wider influence, because many school districts around the country have independently adopted the standards.
Mr. Rosenau said that the spread of the standards to states that included more than half of the nation’s students meant that textbook publishers would be more likely to include information about climate change in books and teacher training materials distributed nationwide.
“In the long run, it’s going to affect everybody,” he said.
Craig Whipkey, a high school science teacher in western Pennsylvania, said he devoted about two weeks of instruction to discussing climate change in each of his three courses.
While he occasionally receives pressure from parents, he said, he teaches from the perspective that evidence of human effects on climate change is compelling.
“I no longer have to prove that it’s happening,” he said. Instead, the focus is, “Here’s what the ramifications are going to be.”
