Canadian Ice Shelves Halve In Six Years

There are 2 basic threads to anti-anthropogenic global warming arguments...

The first is, "It's not really happening, you've cherry-picked your data and/or misinterpreted it." and the refutation usually seems to consist of cherry-picked data with very specific interpretations.

The second is, "It's not anthropogenic, it's natural, because of..." with some reason or other.

For the moment I won't take sides on either thread, but I'm going to take very serious issue with the second. However I get the very distinct feeling with both threads that the real message is, "Since global warming is not real / not anthropogenic, we don't need to modify our actions. We can keep our fossil-fuel-based energy and transportation, unmodified." (and business models, might I add...)

But assuming you're on the second thread, and assuming you're saying that global warming is real, just not man-caused, it must be apparent that we simply cannot keep going the way we are. We must come to grips with a changing environment. Global warming means more energy into the atmosphere, and that means more water evaporates and moves from place to place. Some places get even more water, some places get even less, storms get stronger, and it's not even a smoking-gun kind of thing, it's statistical. No new killer drought or killer flood or killer tornado, just a slow ramp on the severity and frequency of the ones we have.

All the while people living in marginal areas get stressed, our agricultural systems get stressed, our emergency response systems get stressed. It's not "a disaster", it's more of the disasters we've had all along.

Not planning for it, not studying it very carefully to understand the extent, not taking some action to mitigate it, is hiding our head in the sand, and waiting to get smacked in the butt.

When you get flattened by a giant rock, you're just as dead if the rock rolled off a cliff as if it was dropped by a crane. One is "natural", the other "anthropogenic", but you're still dead.
