    There's evidence that around 400,000 years ago, sea levels were 70 feet higher than present due to global warming !!!
    http://www.sciencedaily.com/releases/2009/02/090209205314.htm

    This is higher than predictions for our future by "human caused" global warming "experts" !

    Now, since according to "human caused" global warming "experts" ONLY/PRIMARILY humans are to blame for increasing global warming, than does that mean humans will find a way to pump huge amounts of CO2 back in time 400,000 years ago ?
    After all, "only" humans can cause global warming, so humans must have something to do with the global warming 400,000 years ago.

    But our predictions are based on a relatively short time span of 100-200 years, not the tens of thousands of years it took back then at a pace where animals could adapt. No one is saying only humans can cause global warming, but that we are the primary cause today.

    Well there is one other possiblity I forgot to consider; perhaps some advanced Capitalist alien species came to Earth 400,000+ years ago to dump all their CO2 pollution into our atmosphere in order to save their own planet !

    Again, as spidergoat said, the global warming back then was very slow-paced and animals could adapt. Perhaps if the aliens had done what you have said, we wouldn't be here to talk about it and earth would be venus-like already!

    No no no no no, according to present day political correctness "only" or "primarily" humans are to blame for global warming. Applying this "logic" to past global warming events, there's no other conclusion than humans will find a way to time travel, and will pump enormous amounts of CO2 back in time 400,000+ years ago and create global warming back then. Or perhaps, Capitalist aliens 400,000+ years ago are to blame for dumping their CO2 into the Earth's atmosphere.....

    ???? How many spieces died out, before man ever was a factor, due to climate change.

    90% if I remember correctly.

    http://www.learnnc.org/lp/editions/nchist-twoworlds/1671

    The first single-celled life forms appeared as early as 3,800 million years ago. It then took 2,000 million years for the first cells with nuclei — simple bacteria — to develop, and another 500 million years for multi-celled organisms to evolve. As life forms grew more complex, they diversified. Plants and animals became distinct. Gradually life crept out from the oceans and took over the land. Seed-bearing plants developed, then flowering plants, and finally grasses. Animals developed hard exterior shells for protection, then interior skeletons. Flying insects, amphibians, reptiles, dinosaurs, birds, and finally mammals emerged. Sudden changes in climate caused mass extinctions that wiped out most of the species on earth, making room for new species to evolve and take their places. The ancestors of humans began to walk upright only a few million years ago, and our species, Homo sapiens, emerged only about 120,000 years ago. The first humans arrived in North Carolina just 10,000 years ago — and continued the process of environmental change through hunting, agriculture, and eventually development.

    To help you understand the vastness of the time scales we’re talking about, consider this: If the history of our planet were condensed into a single day, humans would have emerged just 2.3 seconds before midnight, and would have arrived in North Carolina two tenths of a second before midnight — literally the blink of an eye. And if that last two tenths of a second of human habitation were expanded into a full day, Europeans would have arrived at 11:02 pm, and a student now in eighth grade would have been born at 11:58 pm!

    Most of that climate change was cooling though wasn't it? Not global warming which is what we're talking about

    I don' think so. According to present day political correctness "only" or "primarily" humans are to blame for current global warming

    There used to be more volcanic activity in the past. Anyway, whatever nature puts out is in addition to what humans are releasing. Of course, there were greenhouse gasses before the industrial revolution, it is what keeps our planet warm. Your argument is a classic strawman.

    Yes, and when they're faced with the fact that there are other causes of global warming (not humans), it's brushed off with more excuses....

    So we're left to conclude that humans must create a time machine in the future that will pump unimaginable amounts of CO2 into the Earth's past (like 400,000 years ago).

    I don't think the politicians brush off the fact there were causes of global warming other than human 400,000 years ago.

    Mainly because it would be very hard to defend that position considering it is well known that our hominid ancestors were not releasing vast amounts of carbon dioxideo the atmosphere

    Care to show a chart of volcanic activity for the last 4 billion years to prove your point ? and more importantly, does it match global warming events ?
    I know there was more volcanic activity wayyyy back millions and billions of years ago, but the question is, does it match global warming events like the one 400,000 years ago ?

    Correct me if I'm wrong but isn't the volcanic activity question one of those big red herrings like solar cycles and solar activity? Hasn't that been factored in for about the last decade or so?

    That's for modern day global warming. It is not for past. Human's are causing global warming to be much higher than usual as far as the cycle goes. And there is a cycle.

    And shouldn't this belong in the pseudo science or cesspool?

    400,000 years ago carbon releases were most likely caused by volcanic activity. Thus the fundamental cause of the warming is unchanged, only the source.

    Evidence please.
    According to "expert" "human-caused" global warming "experts", humans are the primary or complete reason for global warming....

    who's saying that methane, carbon dioxide, and water vapor aren't greenhouse gases?

    Today, they are, since they are the ones burning off massive amounts of coal and other fossil fuels. Your premise that past global warming disproves anthropocentric global warming is ridiculous, quite the opposite. Past warming proves that our climate is very sensitive to CO2 levels, whatever the source of that CO2 happens to be.

    That alien looks like he's got a bad case of astigmatitus (cross-eye) or something.

    If the current global warming trend is indeed mostly caused by human activity, if runaway warming is indeed a possibility, face it, humanity is screwed, damn human condition. There is no way mankind will reverse its locust-like nature. Intelligent locust clones of topic starter, Buffalo Roam, etc. don't comprehend the idea that Bible's promise of endless happy-go-lucky plunder could be wrong. Why all the right wingers have well developed locust mentality I wonder

    To summarize:

    1) If global warming is indeed a viable, human induced threat - we are screwed one way or another due to the inherent, irreversable mankind's locust like nature. Let's keep on fighting for the best Titanic quarters, damn the warming we can't change our nature to survive, can we?

    2) If global warming is a myth we can do nothing about, if mankind can burn all the coal, oil and gas to survive in 10% CO2 atmosphere, hell, what's the deal, let's go back to the locust thing, don't forget about creativity and dance, and please don't let male ducks (if any will be left) to rape unsuspecting female ducks
