The temperature has changed repeatedly without any evidence of human involvement over those longer time periods we can observe. And the levels of CO2 etc. have changed as well, during time periods when it could not possibly have been blamed on humans. I grew up in Canada, in an area with lots of farms... and I remember the high school trips to different geographical features such as moraines which are the residue of glaciers from long ago. What caused those mile-thick glaciers to melt, given the low levels of human population and the low levels of human technology?

I don't think you understand what you are arguing. Yes, the average temperature of earth has chaged vastly over its history, giving different levels of habitability. At this time, we're in a really good spot for habitability, and we are seeing that we are slipping out of it. There is evidence that some of the temperature change could very well be human made, and thus easy to stop (compared to, say, the emissions of volcanoes). For some reason you argue that nothing should be done, because nothing was done in past massive climate changes, which resolved in mass extinctions. Is anything I'm saying wrong?

  Easy to stop? Lol it's down right impossible and all this discussion is colossal waste of time. Humans are never going to coordinate globally to do this.

    I'm not wasting a lot of time on this, maybe a couple hours a month in looking at papers? I don't think it's a waste of time. Humans don't need to coordonate globally to slow down emissions. I'm sure you are aware of what motivated small groups of people can do. I'm not talking changing laws or protesting, but sabotage and disobedience in general are very efficient and need little coordination.

  Climate has changed in big ways without mass extinctions. The medieval warm period, the little ice age, mid-20th-century cooling. Just three examples. The idea the climate has been stable since the dinosaurs isn't supported by the evidence.

    I mean have you looked at the charts showing the little ice age and the warm medieval period? The variation of temperature is orders of magnitude different to what we are experiencing now - I don't think that it's very relevant, is it? While climate hasn't been "stable" as in "hasn't changed", it has remained in a very narrow band of t°, of which we are slipping out of it at a much faster rate than all your examples. I'd argue it's quite clear we are on the way to an extinction class climate change, are you saying we are not? The hockey stick graph is pretty alarming to me.

      Hockey stick graphs are indeed alarming, but also fraudulent, and the IPCC has even accepted that in the past! Look into the history of these graphs, the Mann lawsuit, the work McIntyre did on showing how these graphs were manufactured etc. After it was shown how Mann did it the NAS investigated and hockey sticks vanished from IPCC reports for around 15 years. Then one snuck back in to the latest report but only in the summary! The graph doesn't appear in the actual scientific review part at all! That's the state the IPCC has degraded to: the summaries for policymakers are completely different to the actual content for scientists and introduce new claims unsupported by the cited research. The graph is still wrong and the techniques that lead to them are blatantly fraudulent (lots of cherry picking, truncating, splicing, even tipping raw data upside down to make it go up instead of down, really horrific stuff).

        I'm sorry, you're spewing nonsense. For anyone having read this far: - "the mann lawsuit" is climategate, where some people found a single sentence out of context that sounded off out of years of emails. Mann sued the people that accused him of skewing the facts, and won a defamation suit. - while you write about things around the hockey stick graph, you dance around describing what they show. You can't "manufacture" a global rise in average t° of over 1°C. - I'm not even certain you are a real human being! Why argue all this, when you can just look at the graph?
