You completely missed the point of my argument, which is that arguing if it is human caused or not is MISSING the point. We should be good stewards of the earth because it is RIGHT, not because of some weak correlations.
However, to respond to your argument, it is quite simple: Correlation does not equal Causation.
There have been many predictions made in the last 100 years, all across the spectrum (from frozen to heated). We cannot just cherry pick what predictions we like, and then claim "see, they were right!"
Fact: The current climate is in a warming trend.
Fact: The sun is hotter now than it was.
Fact: Mars is warmer now than it was.
Do we have enough evidence to say the climate change is warming because of the sun? NO. For the same reason we don't have enough evidence to say it is human caused. The fact of the matter we are talking geological times, and we need thousands of years of measurements to truly understand geological trends. We don't have that. We cannot get that in any reliable means.
So cut it already with the fallacious arguments, and lets get on with being good stewards, because it is the right thing to do.
