I agree, great summary . . . however paragraph 3 « Since methane makes up 0.04% of earth's atmosphere, this theory is debatable » — carbon dioxide, CO₂ is ~0.04% (~420 parts per million by volume) and methane CH₄ is 0.00017% (1.7 parts per million by volume) — even more debatable !

"methane may not warm the earth as previously thought" should read "methane may not warm the earth as much as previously thought"
