News from this month

August seems to be full of news on the global warming front. From today, three bits. A CNN article says Arctic sea ice expected to hit record low. This is not particularly news as it's been predicted widely, but it's one of the global warming affects we really don't want to see happen even faster than current models predict. This is one of the feedback loop problems - the more ice you have, the more sunlight reflects away from the earth, and the more ice you keep (or gain). The less ice you have...well, you get the idea. And there are a lot of feeding grounds up north for key animals in the food chain which depend on typical (cold) conditions.

There is, of course, Hurricane Dean. While we had hurricanes before global warming, they are expected to be be stronger and more frequent as they like warm water. Dean is approaching Jamaica at a category 4 as I write this, and may hit Cancun at a category 5.

And in today's PI, a more upbeat editorial called Global warming: The race is on in our state, by Joe Copeland. He lauds our leaders who have taken strong stances related to global warming and talks about Bracken Hendrick's and Jay Inslee's new book, Apollo's Fire, which according to Copeland suggests that tooling up for new, clean energy will bring up many good things - economically and for the planet. That's the attitude we need - that we can make this better.

A couple of things. The alarmism over the lowest ice mass since the '70s fails to point out that the same media outlets (Time, The nYTimes, etc.) were bemoaning the fact that we were facing an inveitable ice age in the '70s since it was a period of global cooling. Second, the alarmists also fail to point out that while they harp on 1998 as being the warmest year on record that if that is so, then it has been cooling for the last 9 years.
