The scorching summer of 2026 is a stark reminder of the deadly consequences of climate denial. Europe is ablaze, with record-breaking heatwaves and devastating wildfires ravaging the continent and beyond. The UK, in particular, has been grappling with its own heatwave, with temperatures soaring and wildfires forcing evacuations. The crisis is not just a European phenomenon; it's a global crisis with far-reaching implications.
As London's mayor, I've witnessed the devastating impact of climate change firsthand. The city has endured three droughts in the past five years, and the past 11 years have been the hottest on record. The El Niño forming in the Pacific further exacerbates the situation, threatening to intensify the crisis. The climate emergency is no longer a distant threat but an undeniable reality.
My journey as a climate advocate began in 2016 when I declared London a climate emergency, becoming the first mayor of a global city to do so. Since then, I've faced relentless opposition from climate deniers and delayers who have sought to undermine my green policies. The Ulez expansion, a bold initiative to create the largest clean air zone in the world, sparked a fierce debate and even domestic terrorism, as one individual detonated a homemade bomb to protest.
This extreme climate skepticism has only grown louder in the years since. Donald Trump, a notorious climate change denier, has sought to sabotage global climate action by withdrawing the US from the Paris Agreement, cutting clean energy support, and boosting oil and gas production. In the UK, cross-party consensus on the climate crisis has shattered, with opposition politicians and right-wing populists espousing denialism and fatalism.
However, the arguments of climate deniers are baseless. The climate crisis is worsening, but London has demonstrated that we can prepare for its impacts with courage and creativity. We've planted over 640,000 trees, created green spaces, and embraced rewilding to combat flooding. Our city's carbon emissions have decreased by a quarter, and our economy has thrived. The Ulez has helped us achieve legal nitrogen oxide levels, and air pollution-related deaths have plummeted.
Through the C40 Cities network, London collaborates with global cities to tackle the climate emergency. However, we cannot solve this crisis alone. National governments must step up, reaffirm their commitment to net zero, and invest in green projects. The notion that climate action is a luxury is absurd, as droughts and oil-price shocks have a direct impact on the cost of living, healthcare, infrastructure, and more.
The extreme weather events of 2026 are a stark reminder that climate denial is not just delusional but deadly. It's a call to action, urging us to prepare for a hotter future and embrace net zero. The fate of our planet and its inhabitants depends on it.
