When governments know something causes harm, why does change take so long?
The world is on fire. The climate is obviously warming. Yet governments keep investing in pipelines.
Cigarettes are a useful case study.
In 1950, major studies linked smoking to lung cancer. Britain’s Royal College of Physicians warned the public in 1962. The US Surgeon General concluded in 1964 that smoking caused lung cancer and chronic bronchitis. In 1981, studies linked secondhand smoke to lung cancer. In 1986, the Surgeon General concluded that involuntary smoking caused disease, including lung cancer, in healthy nonsmokers.
Everyone knew by 1950. But Canada didn’t ban smoking on flights of two hours or less until 1987, and smoking wasn’t banned on international flights until 1994. Broad bans covering workplaces, restaurants and bars didn’t arrive until the 2000s. Ireland introduced the first comprehensive national workplace ban, including pubs, in 2004.
It took five decades for governments to ban something they knew was killing people.
Tobacco companies were the reason for the delay. One infamous industry memo said, “Doubt is our product.” They funded scientists and front groups, attacked credible studies, lobbied politicians, and recruited hospitality associations to warn of lost jobs and closed businesses. They promoted smoking sections and ventilation as reasonable compromises that left workers exposed. Their goal was to make delay look responsible. In 2006, a US federal court found that major cigarette companies had fraudulently denied dangers they understood.
Momentum finally grew when secondhand smoke was reframed as a workers’ rights issue rather than a private choice. Health groups, unions and local governments built coalitions. Had that framing come sooner, the bans probably would have too.
We’re watching the same playbook with climate change. The Intergovernmental Panel on Climate Change produced its first assessment in 1990, after Exxon’s own scientists had produced accurate warming projections. Fossil fuel interests have since financed misinformation and lobbied against climate policy, exactly as the tobacco industry did.
And here we are, 36 years later, and the world is burning.
Perhaps the answer is that climate activists need to treat this as a human rights issue. A warming planet isn’t an abstract environmental concern; it’s a threat to the right to life, to health, to food, water and shelter. Framed as private cost or consumer choice, action stalls. Framed as a violation of basic human rights, it becomes something governments can be held accountable for. The tobacco fight was won on those terms. The climate fight can be too.
