That warming/cooling happens in cycles, but the current warming cycle is more dramatic than anything in the past, so there must be a component of warming attributable to man's greenhouse gas emissions. How much is not known.
I also understand the current levels are not alarming, but if the trend continues, we could be in trouble a few decades down the road, at which point it will be very hard to reverse.
