Imagine you're a carbon dioxide molecule floating in the atmosphere. How long could you hang out there before other chemical reactions whisk you away?

• Just a few minutes - you're a busy molecule!

• A few hours - you've got some time to chill!

• Hundreds or even thousands of years - you're in for the long haul!

• Indefinitely - you're the ultimate free spirit!

Imagine you have a magic wand and you stopped all carbon dioxide emissions tomorrow! How long do you think it would take for CO2 levels to return to pre-industrial times, before we started burning all those fossil fuels?

• Just a few years, like a short vacation

• A few decades, like watching a tree grow

• Hundreds of years, like the age of a giant tortoise

• Thousands of years, like the time it took to build the pyramids
