Contrary to the climate change deniers, I think the models aren't aggressive enough. I have tried to read climate change predictions, and all models I saw predict CO2 concentration with reference with increases seen in history. The assumption is that history will model future correctly. However, I think that's really wrong. Right now 1.5 billion chinese are at middle income stage. What happens when they start polluting/consuming at first world levels? History hasn't seen such a migration and can't model that. What happens when 1.5 billion in South Asia and 1.5 billion in africa raise their per capita pollution? No historical data has seen effects this extreme. Changes as driving green cars/turning vegan/recycling are really good but might be far from sufficient. What's needed is complete shift to green energy right now. And even that may not be enough.
