Majority of Trump Voters Believe in Climate Change


Despite the presidential candidate’s history of climate change denial, a majority of Donald Trump voters actually believe global warming is real and man-made.

The survey, conducted by the Yale Program on Climate Change Communication and the George Mason University Center for Climate Change Communication, found that 56 percent of people supporting Trump in the 2016 race think global warming is real. On the Democrat side, more than 90 percent of Bernie Sanders and Hillary Clinton supporters believe in climate change.

Key Findings

  • With the exception of Ted Cruz voters, most supporters of the Democratic and Republican candidates think global warming is happening (Sanders: 93 percent, Clinton: 92 percent, Kasich: 71 percent, Trump: 56 percent). By contrast, fewer than half of Ted Cruz supporters—38 percent—think global warming is happening.

  • Supporters of the Democratic candidates are much more likely to think global warming is caused mostly by human activities (79 percent of Sanders supporters and 76 percent of Clinton supporters). Supporters of the Republican candidates are more likely to think it is caused mostly by natural changes in the environment (60 percent of Cruz supporters and 55 percent of Trump supporters) or are divided on the issue—49 percent of Kasich supporters think global warming is mostly caused by humans, 46 percent think it is mostly caused by natural changes.

  • Fewer than half of any candidate’s supporters are aware that virtually all climate scientists have concluded human-caused global warming is happening. However, supporters of the Democratic candidates are the most likely to think at least 90 percent of climate scientists are convinced (Sanders: 38 percent, Clinton: 27 percent). Far fewer supporters of the Republican candidates understand the scientific consensus (Kasich: 11 percent, Trump: 3 percent, Cruz: 2 percent).

  • When asked how worried they are about global warming, a majority of Clinton (83 percent) and Sanders supporters (80 percent) say they are very or somewhat worried about it. Fewer than half of the Republican candidates’ supporters are very or somewhat worried about global warming. Kasich supporters are the most likely to say they are worried (nearly half—44 percent), followed by about one in three Trump supporters (35 percent) and about one in six Cruz supporters (17 percent).

  • Supporters of all Democratic and Republican candidates—except Cruz—are more likely to vote for a presidential candidate who strongly supports taking action to reduce global warming.

  • Conversely, supporters of all Democratic and Republican candidates—except Cruz—are less likely to vote for a presidential candidate who strongly opposes taking action to reduce global warming.

  • While very few voters say global warming will be the most important issue to them when picking a candidate to vote for this year (2 percent), about half (49 percent) say it will be among several important issues. Supporters of the Democratic candidates are most likely to say it will be among several important issues (Sanders: 74 percent, Clinton: 70 percent). By contrast, fewer than half of the Republican candidate supporters say the same (Kasich: 42 percent, Cruz: 33 percent, Trump: 30 percent).

  • Among the issues voters say will influence their vote for President in 2016, global warming ranked 5th in importance of the 23 issues asked about among Sanders voters (59 percent say it is “very important”) and 11th highest for Clinton supporters (51 percent say it is “very important”).

  • By contrast, supporters of the Republican candidates are least likely to say global warming is very important to them among the 23 issues (Trump: 18 percent, Kasich: 13 percent, Cruz: 13 percent).

  • About half of Sanders and Clinton supporters would be willing to join—or are currently participating in—a campaign to convince elected officials to take action to reduce global warming (51 percent and 47 percent, respectively). By contrast, fewer than one in five supporters of the Republican candidates would be willing to do so (Kasich: 17 percent, Trump: 16 percent, Cruz: 11 percent).

  • Registered voters support a broad array of energy policies, including many designed to reduce carbon pollution and dependence on fossil fuels and to promote clean energy. The Democratic candidates’ supporters are the most likely to strongly or somewhat support such policies, but supporters of the Republican candidates do as well, including: Funding more research into renewable energy sources such as solar and wind power (Sanders: 93 percent, Clinton: 91 percent, Kasich: 86 percent, Trump: 76 percent, Cruz: 64 percent); providing tax rebates to people who purchase energy-efficient vehicles or solar panels (Sanders: 94 percent, Clinton: 92 percent, Kasich: 80 percent, Trump: 70 percent, Cruz: 59 percent).

  • At least half of supporters of all candidates except Cruz also would support: Regulating carbon dioxide as a pollutant (Clinton: 91 percent, Sanders: 87 percent, Kasich: 74 percent, Trump: 62 percent, Cruz: 47 percent); requiring fossil fuel companies to pay a carbon tax and using the money to reduce other taxes such as income taxes by an equal amount (Sanders: 88 percent, Clinton: 85 percent, Kasich: 53 percent, Trump: 51 percent, Cruz: 27 percent).

  • Most Sanders and Clinton supporters (90 percent and 87 percent, respectively) and over half of Kasich voters (61 percent) support setting strict carbon dioxide emission limits on existing coal-fired power plants to reduce global warming and improve public health, even if the cost of electricity to consumers and companies would likely increase. Half of Trump supporters do as well (50 percent). By contrast, only 36 percent of Cruz supporters agree.

  • Most Sanders and Clinton supporters (90 percent and 76 percent, respectively) and over half of Kasich voters (61 percent) think the U.S. should reduce its greenhouse gas emissions, regardless of what other countries do. About half of Trump supporters agree (49 percent), but only four in 10 Cruz supporters (40 percent) do.

A powerful volcano on Monday rocked an uninhabited island frequented by tourists about 30 miles off New Zealand's coast. Authorities have confirmed that five people died. They expect that number to rise as some are missing and police officials issued a statement that flights around the islands revealed "no signs of life had been seen at any point,", as The Guardian reported.

"Based on the information we have, we do not believe there are any survivors on the island," the police said in their official statement. "Police is working urgently to confirm the exact number of those who have died, further to the five confirmed deceased already."

The eruption happened on New Zealand's Whakaari/White Island, an islet jutting out of the Bay of Plenty, off the country's North Island. The island is privately owned and is typically visited for day-trips by thousands of tourists every year, according to The New York Times.

At the time of the eruption on Monday, about 50 passengers from the Ovation of Seas were on the island, including more than 30 who were part of a Royal Caribbean cruise trip, according to CNN. Twenty-three people, including the five dead, were evacuated from the island.

The eruption occurred at 2:11 pm local time on Monday, as footage from a crater camera owned and operated by GeoNet, New Zealand's geological hazards agency, shows. The camera also shows dozens of people walking near the rim as white smoke billows just before the eruption, according to Reuters.

Police were unable to reach the island because searing white ash posed imminent danger to rescue workers, said John Tims, New Zealand's deputy police commissioner, as he stood next to Prime Minister Jacinda Ardern in a press conference, as The New York Times reported. Tims said rescue workers would assess the safety of approaching the island on Tuesday morning. "We know the urgency to go back to the island," he told reporters.

"The physical environment is unsafe for us to return to the island," Tims added, as CNN reported. "It's important that we consider the health and safety of rescuers, so we're taking advice from experts going forward."

Authorities have had no communication with anyone on the island. They are frantically working to identify how many people remain and who they are, according to CNN.

Geologists said the eruption is not unexpected and some questioned why the island is open to tourism.

"The volcano has been restless for a few weeks, resulting in the raising of the alert level, so that this eruption is not really a surprise," said Bill McGuire, emeritus professor of geophysical and climate hazards at University College London, as The Guardian reported.

"White Island has been a disaster waiting to happen for many years," said Raymond Cas, emeritus professor at Monash University's school of earth, atmosphere and environment, as The Guardian reported. "Having visited it twice, I have always felt that it was too dangerous to allow the daily tour groups that visit the uninhabited island volcano by boat and helicopter."

The prime minister arrived Monday night in Whakatane, the town closest to the eruption, where day boats visiting the island are docked. Whakatane has a large Maori population.

Ardern met with local council leaders on Monday. She is scheduled to meet with search and rescue teams and will speak to the media at 7 a.m. local time (1 p.m. EST), after drones survey the island, as CNN reported.
