We’re not out of the woods
When the author Hannah Ritchie was 14, she read Six Degrees by Mark Lynas. It mapped out, degree by degree, what a warming world would look like – and by the time she reached six degrees, the picture was apocalyptic. It terrified her.
The scientific consensus has moved significantly since then – but public messaging hasn’t kept up. Most people still carry a persistent sense that we’re heading for catastrophe, and the reality is both better and worse than they think.
If governments do nothing beyond policies already enacted, we’re looking at a world around 2.5 to 3°C warmer by 2100. If countries meet their net-zero pledges, that drops to 1.8°C. None of this means we’re safe. A 2.5°C world still brings devastating heatwaves, the possible end of many coral reefs, and serious damage to food production in the poorest countries. The 1.5°C target is, frankly, gone. Honesty matters here – not to give up, but because countries need time to adapt to the world that’s actually coming. And there’s no cliff edge at 1.5°C. Shaving even a fraction of a degree off the final total protects real lives.
Many people ask themselves: Why bother when China is the world’s largest emitter? Surely that makes everyone else’s efforts pointless? But in 2023 alone, China installed more solar capacity than the US had built across its entire history. In 2024, close to half of all new cars sold there were electric. China is treating the energy transition as one of the biggest economic opportunities of the century.
What about the fear that we’ll hit some point of no return and trigger unstoppable warming? The truth is, there isn’t one global tipping point – there are multiple regional ones. Losing Arctic sea ice in summer, for example, would add around 0.15°C to global temperatures. Hitting several tipping points together might add 0.3 to 0.4°C. That’s serious, but it’s a far cry from a runaway catastrophe. Most of these processes also unfold across centuries, not years.
And public support for action is far stronger than most people realize. A survey of 59,000 people across 63 countries found that 86 percent see climate change as a serious threat. In the US, almost two-thirds of citizens back climate action. And red states generate 70 percent of US wind power, with Texas leading on solar. Support for renewables crosses party lines; people just have different reasons for backing it.
So, what are the most effective actions you can take as an individual? Switch your car, change your heating system, fly less, eat less meat. These matter far more than agonizing over plastic bags and recycling bins. This is what’s known as moral licensing – the tendency to feel that small virtuous acts cancel out the bigger, harder changes you haven’t made. They don’t.
