Britain recorded nearly 2,900 heat-associated deaths in England during May and June 2026 alone. Homes burned in the West Midlands. Wildfires swept Europe. And at the centre of British politics, the governing party's response was to point to existing policy while declining to make a renewed public case for the climate transition it claims to lead. The numbers tell a story of a consensus fracturing along a specific fault line. Two-thirds of Britons (67%) worry about unbearably hot weather becoming more frequent, and 86% attribute the recent heatwaves at least partly to climate change — including 73% of Reform supporters and 87% of Conservative voters. But support for the UK's net zero target has collapsed from 68% in 2024 to 45% today, while opposition nearly doubled from 12% to 23%. Climate fear is decoupling from climate action. Labour MPs see this as a strategic blunder. Jeevun Sandher, MP for Loughborough and a parliamentary private secretary in the energy department, frames climate as an electoral weapon: "Climate is a fight that fires up our base, persuades the middle and splits our opponents." Another MP was blunter: "We're not remotely prepared for the fact that our voter base is radically changing. We're trying to ride two horses." The right is not hesitating. Reform UK's Richard Tice urged people to "enjoy" the heatwaves and celebrated the prospect of better English wine. Claire Coutinho, the shadow energy secretary, called for cheap electricity to take priority over net zero targets, proposing a system built on nuclear and gas where "consumer choice" replaces decarbonisation policy. The framing is deliberate: net zero as elite imposition, cheap energy as populist liberation. Government figures reject the retreat narrative, citing the clean power 2030 target, clean energy investment including nuclear, the transition to EVs and heat pumps, and the refusal to issue new oil and gas licences. A Labour source insisted: "This government has the most ambitious energy climate agenda in British history." But insiders acknowledge that under Keir Starmer, No 10 allowed speculation about a net zero rowback to fester even as the underlying policies never changed. The polling reveals the mechanism of erosion. Luke Tryl of More in Common identifies it precisely: "This is a clear example of elite-level consensus breaking down, leading to public consensus breaking down." Net zero support among Labour 2024 voters hasn't moved. The collapse is concentrated among Conservative voters — a smaller group numerically, but one that drives media narratives. YouGov shows the environment at fourth place on its salience tracker (25%), yet the usual summer spike in climate concern has been muted even as more people say the government isn't doing enough. The Greens and Liberal Democrats are trying to force the pace. Green leader Zack Polanski called for an emergency Cobra meeting before PM Burnham convened one and held a "reality check" conference on extreme heat. The Lib Dems push "climate readiness" — protecting homes from extreme heat while staying unapologetic on emissions cuts. The structural question is whether Labour's silence creates space for these parties to capture the climate vote, or whether the vacuum simply lets the right redefine net zero as unaffordable sacrifice during a cost-of-living crisis.
