You never know you're in a bubble until it pops.

I'm trying mostly to ask questions. And not just trying to stake out a position on something, but also trying to define the stuff we agree on. I'm having battles with comment posters trying to insert a little sense of order so it's not just a long pissing match between the edges, which is what I think a lot of the blogosphere is tending to do.

The responsibility of the scientist or journalist is to convey the context. If you're talking about the Arctic Sea ice, you have to embrace the reality that there's a huge number of other things that influence that on a year-to-year basis.

There are still people who essentially live in intellectual silos and either read Mother Jones or watch Fox News, based on their worldview. And they pick information out that reinforces it rather than keeping an open mind.

Additional federal studies are under way to see if any contamination reaches taps or ground water used for drinking, but the program under which they are conducted, the toxic substances hydrology program of the geological survey, is slated to be eliminated under budget cuts proposed by the Bush administration, government officials said... estrogens and similar compounds are increasingly the focus of research by the Environmental Protection Agency and many scientists because of hints that they alter sexual characteristics in fish and other aquatic species.

The things that happen are an earthquake, another bomb in Iraq, some big jolt on Wall Street in oil prices, and then you have some new study on drought patterns from climate change. Or another little incremental improvement in photovoltaics. Where do those fit in to the daily stream? They don't.

The aspects of global warming that matter most to people - how rapidly will the seas rise? Are hurricanes already getting stronger? How strong will they get as a result of warming? Those are still immersed in complexity. So in those realms that catch people's attention most, or that get used as symbols by environmental campaigners, those facets really do come with significant back-and-forthing.
