It is one of the most divisive topics in the world. But one where it can be hard to know what is true or not. Here are the biggest myths busted.
MYTH 3: CARBON ISN’T A BIG DEAL
Carbon dioxide makes up 0.04 per cent of the Earth’s atmosphere — a tiny fraction.
The problem is that carbon is extremely potent. Think of it like red wine – a splash in spaghetti sauce won’t intoxicate you, but three glasses will.
Burning fossil fuels has significantly increased atmospheric carbon dioxide since the Industrial Revolution, and levels now are higher than at any point in at least 800,000 years.
When the Industrial Revolution began in 1850, the amount was 280 parts per million – or 0.028 per cent of the atmosphere. It’s now 413 parts per million.
We need a little bit of carbon dioxide in the atmosphere to keep the planet warm enough so it’s habitable by humans. But too much acts like a think blanket.
