I see we think the same. Those climate changes are not made by us driving cars and stuff, but by more dramatic actions. We did not have cars 150 years ago, so this source of pollution is eliminated in the previous climate changes! IPCC report is not relevant and I am not sure it should even be taken seriousely.

Consider that the Earth is 70% water. This is huge! Don't you think waters can change climate? In my opinion, ocean has a big contribution to the climate change. But how can oceans be affected? By naval activity: navigation and wars. And we did plenty of that!
