So what I’m reading is that these gas absorb the light from the sun and keeps it trapped on the earth.
What I don’t get is how is it letting the light and heat in from the sun in, but not the light and heat reflected from the Earth out? If it’s a barrier, shouldn’t it block both ways? If it’s not a barrier, how is it trapping the heat?

Followup ELI5: Why can’t we open the atmosphere and “vent” some of this heat out? I know holes in the ozone are bad, but would it let the heat out?
