Let's try this, then:
Pay attention:
1) Electric current encountering resistance generates heat. Falsifiable, and tested.
2) The VAST majority of heat from electrical resistance is generated by humans. Falsifiable, and tested.
3) Man's use of electricity correlates directly with the hockey-stick. Falsifiable, and tested.
Unplug your computer to save the planet!!!
(By the way, don't you mean VERIFIABLE? Wouldn't it weaken the argument to use falsified data?)
It could be that in a system as vast and complex as the Earth's atmosphere, you probably can't draw up a bulleted list to explain all the reasons we're observing what we're observing. Unless you're God, you're just guessing along with everyone else. It isn't like you have a series of scale model Earths you can use to run your tests.
Here's another list...
A) We've (supposedly) been hotter than we are before, when there were (supposedly) no humans around to blame.
B) The Sahara (supposedly) used to be fertile.
C) Humans are extremely resilient creatures.
D) The Earth is quite likely more resilient, and is unlikely to explode in a ball of fire if it gets too hot. It may require some adapting, but life WILL go on.
E) Polar bears are down, but sharks are up. See D, above.
F) The impact of changing the entire human energy experience is not insignificant, and could well upend society itself if not managed properly.
G) Every government on the planet is currently ran by complete idiots, and even if they knew EXACTLY what to do, they'd still fuck up the implementation.
H) It is entirely possible that 'humans > polar bears' is a valid opinion to have.
Lists are fun. I could go on and on... :)
