SHARM EL-SHEIKH, Egypt (AP) — The world is getting

hotter and more crowded and the two issues are connected, but

not quite as much as people might think, experts say.

On Tuesday somewhere a baby will be born that will be the

globe’s 8 billionth person, according to a projection by the United

Nations and other experts. The Earth has warmed almost 1.6 degrees

Fahrenheit since the world hit the 4 billion mark in 1974.

Climate and population is a touchy subject for scientists and

officials. While more people consuming energy, mostly from the

burning of fossil fuels, is warming the planet, the key issue isn’t

the number of people as much as how a small fraction of those

people are causing way more than their share of carbon pollution,

several climate and population experts told The Associated Press.
