". To all you science people, correlation does not equal causation. "
no shit, Sherlock.
" How else do you explain the many periods of warming and cooling in the past long before humans even existed?"
There are different way the earth can warm. The effect of shoving more green house gasses into the atmosphere causes warming on top of other trends. There is no doubt about this at all.
" I rest my case"
You did not, in any way, 'make a case'. You might want to learn what the means.
If you want to make a case, you need to start by showing which one of these is false:
1) The Earth gets lots of light from the sun
2) Visible light emits IR when it strike something
3) CO2 absorbs energy from IR
4) Humans but more green house gasses into the air then can be absorbed.
The basic science on warming is trivial. Literally any of these can, nad have, been test by any decent College lab. Hell, even A good high school lab could do it. This is why deniers never talk about the actual science and only talk about cherry picked data points, or make ad homs.
So, the climate is warming due to more energy being trapped.
Climate Change is the impact AGW has on the climate. They are related but separate issues.
So, why would adding energy to a system not change it?
At this point, some knuckle head is about to slam his meat hooks onto his keyboard in what he thinks is a clever retort,. I will take this time to remind him the new equilibrium is only reach when the change in energy stops, and there is no rule saying the planet need to be livable when equilibrium is achieved.
More to the point:
Why do you think there is a 97% consensus? Why do you think countries whose best interest would be that there is no AGW agree there is AGW?
Some people think there is a weird conspiracy. That would mean the China is in on it for no reason. Why?
