Address some extreme statements of proponents and skeptics and give counter arguments.
Skeptics:
Rising levels of GHGs in the 20th century have not caused the Earth to warm.
Not true, because:
1. We understand the physics of greenhouse gases (problem is with feedbacks).
2. Earth's history revealed relationship between greenhouse gases and temperature.
3. Venus is an example of a greenhouse effect purely from CO2.
