If you think the Superfreaks had demonstrated the truth of the Dunning-Kruger effect well enough, especially after this further hammering, and their attempt to gain everyone's esteem by having NewsCorp send out copyright nastygrams, think again.
Here's some science, via Lou Grinzo's blog. We've been taking very, very thin samples of the leafmould in the bottom of a rather special Irish lake (peat - not much oxygen, so things *last*), and it's possible to draw some interesting conclusions about the Younger Dryas event, which flipped the planet into an ice age 13,000 years ago after a huge ice barrier in North America collapsed and let vast amounts of fresh water pour into the Atlantic.
The killer detail, literally: the new ice age kicked off within months. We had thought it took decades, but instead it tore in within a year. A year. No time to adjust; not even that much time to flee.
This should surely kill off any daft ideas of fiddling with the atmosphere. Shouldn't it?
