I've said this before in similar threads, just open your eyes and look around, profound changes are already under way. A constant barrage of "this is a natural cycle" isn't going to cut it anymore. Theres nothing natural about burning untold billions of tons of fossil fuels over several hundred years. Almost anyone can see that. Almost.....

And how would you know what that natural cycle is to know its not cutting it?
If there was a natural warming and cooling cycle (and I only say if as it applies the current trends, we know there IS one regardless) how would you know if it 'cut it'?
Saying things like 'profound changes' mean nothing, we don't even know what normal changes are. How long have we been studying this kind of thing with any precision? Decades at best, with a smattering of temperature data and some anecdotal reports.
I can make two claims with equal certainty. The earth as some point in the future will be warmer. Likewise the earth as some point in the future will be colder. We know this, it happened 1000's of times in the past, and quite personally I'm far more worried about humanity and the next ice age than humanity and global warming, but still both will happen to us.
To sit here and decide that we MUST be doing it based on what we currently know is almost a form of hubris. Some things, man just doesn't have that much say in, one way or the other.
