The evidence that points to it being man "accelerated", anyway, is the record levels of CO2.
The record levels of CO2 have NOT increased the global mean temp even one tenth of one degree. In fact it has not risen by even one half of one tenth of one degree. That pretty much means it ain't gone up in the last 15 years when the amount of CO2 has steadily increased in the same time. The empirical evidence does not support your claim.
What else ya got to fling at the wall?
