In 2026, the question is no longer whether we act on the climate crisis, but how fast we do so. Most people accept the science, which shows that the Earth’s average surface temperatures have increased significantly over the past century. It is hard to deny this in a week where the UK is yet again experiencing record-breaking heat, although one climate sceptic told me online recently that “it’s just weather”. Yes, there have been hot periods in recent history, but these are becoming more frequent and more prolonged, with global temperatures set to rise by 1.5°C to 2°C by 2050. While that may sound like a small number, these increases will lead to farmers’ crops failing more regularly, threatening food security. People’s health will be impacted. Sea temperatures will further increase; this will melt ice sheets and release massive amounts of carbon and methane into the permafrost, further increasing temperatures. The net zero brand, however, has become toxic, failing to clearly communicate what must be done and why. Measures to deal with climate and the environment are not “nice to haves”—they are essential to protect the country’s ecosystem, agriculture and infrastructure. It is no longer about whether we can afford to take action; it is about whether we can afford not to do so. If we do, our economy will actually benefit. We must confront the misinformation directly and put forward credible, practical solutions. The populist right promotes the misleading claim that the UK can secure its energy by drilling more oil and gas in the North sea, but in reality, projects such as the Rosebank oilfield would deliver only a relatively small supply of oil and be subject to global price shocks, all while causing significant environmental damage and giving more profits to oil giants. True energy security and lower costs will come from sustained investment in renewable energy, not from doubling down on fossil fuels. Some 37 years ago, Margaret Thatcher stood before the UN General Assembly and warned of the dangers of rising carbon emissions and their impact on the Earth’s climate. At the time, the Conservatives respected that evidence and engaged seriously with the science, but today the party is a pound shop version of its former self, more preoccupied with chasing Reform votes than offering serious solutions to the challenges facing our country. We urgently need to tell a better story on climate change and to show the public how policies will benefit them where it matters—in their pocket. During the last heatwave a few weeks ago, more than 80% of the energy in the grid came from renewable sources. That is a fantastic news story, and the public are set to reap the benefits from the planned decoupling of gas and electricity prices. Across the UK, we are already seeing warmer, wetter winters and hotter, drier summers, but this is not a task for DESNZ alone. A golden thread of safeguarding our environment for future generations must run across all Departments.
