Nice Article on the Alaska Heatwave

Via Bruce Sterling’s Twitter feed, and thus opening yet another opportunity to get Bruce to actually show up here and liven things up:

There’s an interesting article on New Scientist about the Alaska heatwave. One may object to:

As to whether global warming is what is causing the jet stream to deviate, Petrescu says there is too little data as yet. “Right now, we can’t say yes or no,” he says.

Or

Meteorologists at the US National Oceanic and Atmospheric Administration (NOAA) warned last week that it is far too early to link the freak Alaskan weather to climate change. “The jury is out on any individual events and their relationship to specific long term drivers,” said Deke Arndt, chief of climate monitoring at NOAA’s National Climatic Data Center in Asheville, North Carolina, during a routine monthly climate teleconference. “It takes time to connect the dots.”

This of course tells only half the story, and the scientists in question are toeing the line and not painting targets on their backs. (Which way was the funding pressure supposed to work again?)

But this is exactly the misuse of the phrase “global warming” that drives me crazy: “As to whether global warming is what is causing the jet stream to deviate, Petrescu says there is too little data as yet.” It is not the rise in the mean surface temperature that is causing the jet stream to deviate.
