Unlike in recent election cycles, most Republican presidential hopefuls this time around didn’t flat out deny that the climate crisis is real. But on the Fox News debate stage, they made clear that they’re not interested in dwelling on the issues – or doing much about it.
On Tuesday night, the eight candidates were asked to raise their hands if they believed in the reality of human-caused global heating. They all punted.
The Florida governor, Ron DeSantis, immediately derailed efforts to elicit a clear yes or no response. “Let’s have this debate,” he said, before proceeding not to have it at all, instead criticising Joe Biden’s response to the fires in Maui.
Vivek Ramaswamy, a biotech entrepreneur, was notably the only candidate to full-throatedly deny climate science, making the unsubstantiated claim that “more people are dying due to bad climate change policies than they are due to actual climate change”.
There’s no discernible trend of deaths linked to policies encouraging renewable energy. However, extreme heat – fueled by the climate crisis – killed about 1,500 people last year, according to Centers for Disease Control records. Researchers estimate that the true figure is closer to 10,000 people every year.
Former UN ambassador Nikki Haley, on the other hand, said “climate change is real” but then pushed off all responsibility to take care of it on India and China. Both those countries have lower per-capita carbon emissions than the US. And as of the latest figures, from 2021, no country had emitted more carbon dioxide since 1850 than the US.
The South Carolina senator Tim Scott didn’t offer much in terms of solutions earlier, pointing a finger at the continent of Africa, as well as India and China. Africa accounts for one-fifth of the world’s population and produces about 3% of global greenhouse gas emissions, according to the International Energy Association, while disproportionately experiencing the consequences of climate chaos. The US is responsible for about 14% of global emissions.
Nobody meaningfully addressed the question posed by Alexander Diaz of the Young America’s Foundation, a conservative youth organisation: “How will you as both president of the United States and leader of the Republican party calm their fears that the Republican party doesn’t care about climate change?”
In a Washington Post/University of Maryland poll, 35% of Republicans and Republican-leaning independents said they think climate change is a major factor in the extreme heat that the US has experienced recently, compared with 85% of those who lean Democratic. Overall, nearly two-thirds of Americans who experienced extremely hot days said climate change was a major factor.
Young Republican voters, however, seem increasingly concerned about the climate crisis. A 2022 Pew poll found that 73% of Republicans aged 18-39 thought climate change was an extremely/very or somewhat serious issue.
Meanwhile, the rightwing groups have been working to boost the fossil fuel industry while undermining the energy transition. Project 2025, a $22m endeavor by the climate-denying thinktank the Heritage Foundation, has developed a presidential proposal that lays out how a Republican president could dismantle US climate policy within their first 180 days in office.
The GOP candidates who have held public office have already given voters a glimpse of how they might approach the climate crisis. Governor DeSantis has supported projects to build seawalls and improve drainage systems as Florida faces increasingly powerful hurricanes and storm surges, as well as threats from sea level rise. But he has refused to acknowledge the role of global heating on these disasters, scoffing at the “politicization of the weather” and pushing bills banning Florida cities from adopting 100% clean energy goals. He also barred the state’s pension fund from considering the climate crisis when making investment decisions.
Donald Trump, who did not attend the debate, has done even more to impede climate action. As president, he rolled back nearly 100 climate regulations, according a New York Times tally.
Among the candidates who do support doing anything about the climate crisis, most think that thing should be carbon capture. Haley, who as US ambassador to the United Nations helped orchestrate the US withdrawal from the Paris agreement, has presented carbon capture technologies and tree planting as a way to keep burning fossil fuels while slowing the climate crisis.
The consensus among climate scientists is that while such technologies could be a tool in fighting global heating, an overreliance on them could cause the world to surpass climate tipping points.
