So, we have increased the amount of CO2, and other gases in the atmosphere, we've polluted much of the planet, and altered many eco-systems. We have essentially disrupted Earth's equation, or the 'normal state' of things. So, what is likely to result? A) Nothing changes at all (despite the "elements of the equation" changing) B) Things change for the better (more fresh water, cleaner air, lots of vibrant ecosystems, the weather gets MORE predictable) C) Things change for the worse...(less fresh water, dirtier air, loss of vibrant ecosystems, the weather gets LESS predictable) Mathematically, option A is impossible. You decide which of the other two is more likely (and then give a shit if that's your nature).
