Well it's nice to get a reasoned external assessment of the arguments but my worry is that the arguments against human-induced climate change are seriously flawed. They are based on, for example, inconsistencies in model predictions -- but you should expect this, because the climate is a highly complex system and is therefore sensitive to input. Or an observation that the temperatures globally haven't risen much in the last ten years or so -- which is, I believe, true, but at temperature averages that are among the highest in recorded history. Or, one or two years ago, there was an annual increase in the levels of Arctic Sea Ice. Which, again, may be true, but the level it was increasing from was the lowest it had ever been.
And so on. Both sides are, I'm sure, guilty of selective data use to support their own arguments. What gets missed as a result is the big picture, which is that human activity is disrupting the long-term carbon cycle and messing with the planet in a huge and unsustainable manner. The AGW movement, for me, is making an argument equivalent to looking at an 80-year-old habitual smoker/ drinker who's suffered no significant health issues and concluding that smoking is, after all, not bad for you at all. It's an awful argument there -- it's equally awful here.
