Or try refuting global warming. Temperatures have stopped warming for more than a decade? That's just a temporary "pause" in the warming that we just know is going to come roaring back any day now. Antarctic ice is growing? That's actually caused by the melting of ice, don't you know. A vicious cold snap that sets record low temperatures? That's just because the North Pole is actually warming. So if the winter is warm, that's global warming, but if the winter is cold, that's global warming, too. If sea ice is disappearing, that's global warming, but if sea ice is increasing, that's global warming.
Now we can see what they mean when the warmthers say that global warming is supported by an ironclad scientific consensus. The theory is so irrefutable that it's unfalsifiable!
Which is to say that it has become a cognitive spaghetti bowl full of ad hoc rationalizations, rather than a genuine scientific hypothesis.
