    So most of earths history suffered from global warming?
    Even the hundreds of millions of years before this stupid term was invented by useless scientists.

    Wonder how life was able to survive this in the past million years,
    especially polar bears.
    Easily i guess,as money scams don’t effect climate or lives but the wallets of the dumb who rather trust the deceiver(and pay him) than the spoil sport who exposes their dumbness.

    This is exactly opposite of what I’ve always read: that the current warm interglacial is the anomaly, not the normal. Am I misunderstanding something, especially given the graph which shows what the global temperature was like over the past 850K years?
