Greenhouse gases in the atmosphere (methane, carbon dioxide, etc.) let visible light pass through, but absorb infrared light
This causes the earth to heat up.
The warmer atmosphere emits more infrared light, which tends to be re-absorbed
Since the industrial age began around 1750, atmospheric carbon dioxide has increased by 40% and methane has increased by 150%.
Such increases cause extra infrared light absorption, further heating Earth above its typical temperature range (even as energy from the sun stays basically the same).
Energy that gets to Earth has an even harder time leaving it causing Earth’s average temperature to increase–– producing global climate change.
Emissions are measurable. Temperature changes are measurable. The effects are measurable.
They lead to the same conclusion. 97% of scientists agree. The standouts have ties to fossil fuel industries. TRUMP WILL 100%
