BTN Greenhouse Gasses

Some of the world’s  op scientists say that greenhouse gas levels are now the highest they’ve been in 800 000 years. The warning was contained in the United nation’s latest report on climate change which was released last week. Heat from the sun keeps us all happy, making trees stay alive and even making fruit grow. But how does too much heat affect the earth?

When heat hits the ozone layer, part of it gets absorbed and part of it goes up into space. On the way, some of it gets stuck by something called greenhouse gasses. Carbon dioxide is a greenhouse gas.

A question I still have is why do some gases absorb heat and some reflect heat?
