Reform UK’s new chairman has repeatedly attacked climate targets as “madness” and “a killer”, supported fracking, and falsely dismissed the role of carbon emissions on heatwaves.

David Bull, a TalkTV presenter and former doctor, was appointed as the chair of Nigel Farage’s right-wing populist party this week following the resignation of its previous chair Zia Yusuf.

Yusuf, a luxury lifestyle entrepreneur, said that working to achieve a Reform government was no longer a good use of his time, before returning two days later in a new role.

Bull is now loyal Farage supporter, despite having called the Reform leader a “dangerous, prejudiced idiot” in 2014. He was a member of the European Parliament in 2019 for the Brexit Party, the predecessor to Reform UK, and served as Reform’s deputy leader from March 2021 to July 2024.

In a series of social media posts, Bull has repeatedly attacked the UK’s target to cut carbon emissions to net zero by 2050, which climate scientists have said is needed to limit global warming to 1.5C.

On the eve of the 2024 general election, Bull posted on Elon Musk’s website X.com: “Net Zero is a killer. It’s killing British jobs, communities and the economy. Only Reform UK will scrap Net Zero.”

In reality, according to risk management experts the Institute and Faculty of Actuaries (IFoA), 50 percent could be wiped off the global economy between 2070 and 2090 if runaway temperature increases are not halted, while there could be more than 4 billion deaths.

In January of this year, he shared a Telegraph story about a lull in wind power and claimed that it made “a complete mockery” of Labour’s net zero chief Ed Miliband and his “religious obsession” with renewable energy.

As revealed by DeSmog, Reform’s constitution gives sweeping powers to its chairman, who cannot be formally sacked by the party leader.

Reform wants to scrap the UK’s net zero target entirely, stop subsidies for renewable energy, impose a “windfall tax” on wind and solar companies, approve new oil and gas extraction, and open new coal mines. The party’s leaders have also repeatedly made false statements about climate change.

As DeSmog has reported, Reform received £2.3 million between the 2019 and 2024 general elections from climate deniers, fossil fuel investors, and polluting interests. It is also openly seeking donations from oil executives.

David Bull’s Climate Stance

In May 2023, Bull hosted a TalkTV segment called “the madness of net zero”. He began by saying: “I think all of us feel that the climate is changing and that we want to go to net zero”. This is out of step with Reform’s position, and the title of his segment.

But he went on to claim, of the UK’s record heatwave the previous summer, “we don’t know whether that is a result of man-made emissions”. 

This contradicts the Intergovernmental Panel on Climate Change (IPCC), the Met Office, and a study by the World Weather Attribution service, which said the 2022 heatwave was made “at least 10 times more likely” by human-caused climate change. 

In the same segment, Bull suggested net zero was “subjecting people in this country to become poorer”. In reality, according to the Confederation of British Industry (CBI), the UK’s net zero economy grew by 10 percent in 2024, employing almost a million people in full-time jobs with an average wage of £43,000 – £5,600 higher than the national average.

In October 2021, Bull endorsed a campaign by climate denial pressure group CAR26 for a Brexit-style referendum on net zero, and shared a poll commissioned by the group, adding: “We absolutely MUST have a referendum on the Government’s net zero policy. Retweet if you agree.”

CAR26 director Lois Perry now runs the UK-EU branch of the Heartland Institute, a notorious U.S. climate denial think tank. The UK-EU branch was launched in December by Reform’s leader Farage.

In November 2021, while the UK hosted the flagship UN COP26 climate summit, Bull attacked what he called “the hypocrisy of COP26”. He told TalkTV: “It is obscene. The hypocrisy that they [world leaders] fly in on private jets. People are sick and tired of being told what to do.” 

In April 2022, Bull posted on X.com predicting that “Net Zero will be the new Brexit. It will be the most defining issue at the next general election”. Despite Reform’s best efforts, the pro-net zero Labour Party won a historically large majority.

Bull has also supported overturning the UK’s ban on fracking for shale gas.

In October 2022, when prime minister Rishi Sunak reversed the decision by his predecessor Liz Truss to lift the ban, Bull posted: “MASSIVE MISTAKE. We need cheap energy NOW. Fracking has allowed the US to have 100-200 years of cheap energy.”

Aside from the pollution caused by burning shale gas, fracking is environmentally controversial due to its triggering of earth tremors, and the vast amount of water that it uses. The House of Commons Environmental Audit Committee – a body of MPs that advises the government on climate matters – concluded in 2019 that fracking was incompatible with the UK’s climate goals.

TalkTV was launched in 2022 by Rupert Murdoch’s News UK as a rival to GB News, but in 2024 it switched to an online streaming service.

As DeSmog has reported, TalkTV presenters have frequently attacked climate action. In the COP26 segment, Bull was interviewed by fellow TalkTV host Mike Graham, who has declared on social media that “climate change is a load of old bollocks”.

Bull has resigned as a TalkTV presenter, following his appointment as Reform’s chair.
