Greenhouse gases raise Earth temp

We all need to understand climate science.

Climate fundamentals are simple: Sunshine warms the Earth, and the Earth radiates heat back into space as infrared. Earth’s temperature results from how much radiant heat gets trapped by greenhouse gases in the atmosphere. GHGs are trace gases but have a disproportionate influence on temperatures.

Nitrogen, oxygen and argon represent 78%, 21%, and 0.9% of our atmosphere and are not greenhouse gases.

Greenhouse gases only make up a fraction of the remaining 0.1%; gases such as carbon-dioxide, methane and nitrous oxide are Earth’s “thermostat gases.”
