All of the effects that you mention have been evaluated. The current warming trend is being augmented by the increasing concentration of CO2 in the atmosphere. Natural variability cannot account for all of the observed warming.
I can back up all of these statements with references to scientific literature, if you would be willing to consider what they say. From long experience, I know that this effort is usually fruitless for someone who already has their mind made up. Tell me if you're actually interested -- I won't waste my time or yours if you aren't.
We can just agree to disagree, since I consider that scientific literature to be agenda-driven crap. I grant that temperatures are rising. I grant that CO2 levels are rising. I laugh at the idea that humans are changing the global climate.
