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.
