The natural atmospheric variations will play a part in any weather, even that related to global warming unless something very drastic happens.
The claim made by Johnny was not related to anything the paper quoted would refute in any way.
Being caused by AGW and being caused by natural variability are two very different and separate entities.
No, they are not. The mechanism will be that of natural variations, but the situation would not have been the same without the artifical input. If the CO2 level had remained at ~280 ppm the natural variations would most probably not been the same as was seen.
Increased storms and droughts will also be the reuslt of the natural weather variations but again those variations are there partially as a result of the changing temperature, which is partially the result of the increased CO2 levels in the atmosphere.
Just as HIV never kills anyone, it does set the stage for the more natural causes such as pneumonia. That does not mean contracting HIV may not cause an early death, just that HIV will not be the final cause of death.
