It seems a few here have missed the point of my previous post. The specific content of those charts is not important. In fact, the idea that all of those things are completely unrelated is the point.
Sure, we may have eliminated "volcanoes, sun activity, natural climate cycles etc." But that is by no means an elimination of any other cause. It is also by no means a confirmation of a man-made cause. As I've said before: in order to do that, one would need a "control" Earth with no humans [but otherwise identical conditions] which does not show a similar trend of climate change. Therefore, the answer is not "simply 'yes'". There is no concrete evidence as of yet that some other [perhaps completely unknown] cause isn't driving the current climate.
There are no "obvious" relations in science. If a theory cannot be repeatably tested by anyone with the means and always produce the same results, then it remains just that - a theory. A guess. Even if it does "seem obvious". Science is not how we feel about something. And sometimes it doesn't even make sense to us, based on our current understanding of the universe. What is [or should be] obvious is that we don't know everything. In fact, we know very little - and understand even less - about how even seemingly simple things actually work. Like gravity and light, for instance.
All of that is not to say that we should not make an effort to find cleaner and renewable energy sources. That's just common sense. And I do - in fact - think that this would have a beneficial effect on the climate. But to state that it is in any way a fact that we know the current climate situation is entirely and only caused by human activity is simply not true. At least not by scientific standards. We can say it is probably true. Even highly likely. But that is all.
Sometimes science does, by necessity, make assumptions. And those assumptions can be extremely useful - even if they are not entirely correct. But I believe it is a disservice to science to say - in this and some other areas - that the matter is settled. It isn't, and may never be. But that also doesn't mean we shouldn't try to do something about it.
