I don't know where you get your interpretation of the IPCC's mission or aggregate findings, but where exactly does it state that "most of the increase in temperature was due to natural causes and natural cycles"? If anything, the 2001 assessment affirms a significant human influence. Were does the IPCC report highlight natural processes that account for "most" of the trend? Link please. And 2. The current interglacial period is apparently one of the longer ones, expected to last thousands of years more . you see thats the problem. they have lumped it all together so that
all the increases are counted as human caused. they have a small print hidden somewhere telling that they lumped it all together because they were talking about the total increase, where as, if you want to know how much is human caused you have to seperated out the other causes. They dont mention them, merely add their influence into the human caused ones. I have already given several links to places where the scientist have talked about other causes.
Regardless of all this argument, or the ten+ year old articles used to support it, there's still no peer-reviewed study that successfully indicates there are natural forcings that can account for most of the current (and ongoing) warming trend. Period.
sure if they are all lumped together there is no evidence that anything not accounted for is in any way resposible for the change. after all they have already accounted for natural cycle of the sea level changes, the solar flare and the solar output increase, not to mention volcanos and earth el nino and el nina, and we all know that man is responsible for all of these. what else coudl be the cause of the global warming? how can you claim it was from a single magazine article written years ago when they discuss ice cores that were taken last year.
Meanwhile, the science supporting the human-amplified greenhouse effect as the primary cause, and suggesting that we're just seeing the beginning of this process (subject to the delay of thermal inertia and the amplification of feedback effects) has only gained strength
sure, human amplified solar effects, and human amplified volcano effects are all part of that. im not saying that man has not had some effect, but he is not nor has he ever been the primary cause of what has happen.
