The evidence for this hypothesis is the well established physics of the greenhouse effect itself and the correlation of increasing global carbon dioxide concentration with rising global temperature. (newstatesman.com)
Not the problem here, you, generic, have moved the goal posts, you have taken out actual opposition on the substance of «climate change» which should be the actual physics of the Greenhouse Effect, and now promote your view as the «opposition», and for the most part in discussions supposedly open to discussion, the view of the real «deniers» is written out...

While you might argue that the best quantitative and detailed estimates come from computer models, the physics of the greenhouse effect are very basic indeed. (realclimate.org)
