Facts? 42 billion tonnes of carbon dioxide are released into the atmosphere by humans every year changing the atmosphere composition from ~300 ppm 100 years ago to ~420 ppm today. CO2 Is chemically stable in the atmosphere and can persist for centuries. CO2 catches thermal radiation from the earth and traps it.

These are all scientific facts that are indisputable. We can also show that its a fact heat affects weather and its not a very far stretch to trapping more heat every year with more CO2 affects global weather. Trapping more heat across the globe AKA global warming are indisputable facts. We can measure CO2 levels every year and global temperature trends.

Doesnt matter who says it, there's a ton of peer reviewed science for every statement there. What's to dispute?
