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?
In: 950
it comes in as light and should go out as infrared (heat).
when you light something for long enough it becomes hotter. and this energie can also be sent out as infrared light that we cannot see.
now the co2 only blocks the infrared.
so the light goes through warms up the earth and earth is unable to release the heat and gehts heated up more and more.
