    So why not start the graph in 20,000 BC when half of the World was under a glacier?

    Answer, because this tells the real story.

    PS. As an interesting anecdote, on the year that graph started in 1970, and for every year after, the sea ice around Antarctica, has increased, to the record levels that we have now.

    Please refute, if not true.

    What you seem to fail to understand is that although there were no people around at 800,000 BC there are a number of perfectly reasonable proxies which show relatively straight forward relationships with temperature - isotope chemistry is one such example.

    He's referring to the Milankovich cycles, which pretty much predict the earth should be entering a cooling phase, not a warming one.

    Nice to see the IPCC has caught up with me...

    actually, check it out, it's not what , i at least, expected. i'm still trying to find more data on it.

    I know there were no people then, it is the people now who create the false image, and manipulate data for the sake of the almighty grant.

    That is what I said, that his own cycle predicts a new ice age, at any time. So in 100, 200 or a thousand years we could well be building CO2 creation factories to warm the Earth..........

    Reality, is seldom what you know, and never what you are sure of.

    That's beside the point.

    Your statement implied that the snowball earth was recent, it wasn't.
    Your statement implied the earth has warmed since then, while this is technically correct, temperatures in the Jurassic were substantially higher than they are now. Would mamals have been able to evolve in the 30 °C average temps of the Devonian. I could just as easily argue that the earth has been cooling for the last 4.5 billion years so we should be especially concerned by the recent warming trend.

    I've been saying for at least the last 3 or 4 years that the current trends would have to continue for between 30 and 70 years for the residual error to be <= 0.

    It is not beside any point, as you are one of the life forms, that was created by the gift of global warming. You may prove me wrong, by moving to the South Pole.

    It's not 'his' cycle. You really are clueless aren't you?

    The milankovich cycles:

    Please Register or Log in to view the hidden image!



    The currently accepted hypothesis is that there are two effects at play that govern earths climate. ALL climate models start with the amount of sunlight the earth receives and proceed from there. Orbital variations and polar wandering combine to change the average amount of sunlight the earth receives at various times of year and therefore the average temperature. If you want to know what difference polar wander might make, stop and imagine, for a minute, what the climate in the northern hemisphere would be like if perihelion co-incided with the northern hemisphere summer (instead of its winter) and aphelion co-incided with northern hemispheres winter.

    It is completely beside the point. If you genuinely think that then you should disprove it by moving into a volcano - which is almost as absurd as the point you're making.

    After all, could you and I really exist without the global cooling since the Devonian, or the Hadean?

    He inferred the cycle here first, so he introduced this into the conversation. And again there are no computer models, that can predict the weather in Kansas City for June 8th next Summer, can your model do that? But of course it can predict the future long after that. Ok, if you say so, and again if not for Global warming, New York state would be under hundreds to thousands of feet of ice, so without the Big Apple, we would not have Broadway and thus no--->

    No he didn't - any discussion of climate change neccessarily involves a discussion of the milankovich cycles.

    Weather is not the same as climate.

    And if not for global cooling it'd still be under hundreds of feet of water, or worse, lava, so there'd still be no broadway.

    Global Warming is a "killer of bears" - not just polar but grizzly bears too:
    But great for us Tree Beetles.

    Humans are stupid, but we beetles thank you for burning fossil fuels. Make more eggs, mommy!
    Surprisingly, these beetles are NOT why large forest fires are now more common (Forest more a source of CO2 than a sink) It is the warmer and drying weather that is the cause. Soot from these fire is lowering the albedo of ice covered Greenland, etc. so larger forest fires are part of two different positive feed-back systems.

    ah, but then, we have the superinterglacials of ms 11, 31, 49, 55, 77, 87, 91, and 93 which all lasted 25kyrs or longer.
    The lake elgygytgyn team claimed that they were unexplained via any known climate mechanism or model.
    But they happened none-the-less.
    We just may be ignorant of something important beyond the milankovich cycles.

    Could mis 1 be another super-interglacial?

    Sure. That would not explain the rapid warming, counter to all known natural factors, of the past couple of hundred years, of course.

    Those big cycles take thousands of years to play out.

    Yes. AGW is real, and getting worse with price of oil in steep decline:

    Does CO₂ absorb heat? If so, then does human activity affect the climate?
