A baby born today will have a special birthday... forever
It's a milestone for earth's population today.
The 8-billionth baby is about to be born somewhere, sometime, on a planet some scientists say is getting hotter.
The United Nations says the birth comes at a time when growth of earth's population has been slowing in recent years, and the number should be seen as a positive, and not so negative.
But experts in climate science and population both tell the COP 27 climate conference in Egypt the two issues aren't quite as connected as they seem.
Although more people consume more energy and put more carbon dioxide in the air, experts say it's not a simple numbers game, it's about consumption.
The poorest half of the world's population only produces 7% of the carbon emissions.
Experts say it's not too many people, but rich people polluting too much.
