I'm trying to figure out whether there's an inexpensive filtration method that'll catch particles that small.

You should be able to get pads that can filter down to 1 micron at your local tropical fish store, and they're usually under 10 bucks. I don't know if you'd want to pour something you'd drink through them, but brand new out of the box I don't think there would be anything wrong with them.

What you would look for are replacement pads for aquarium filters and then cut it open and put it over whatever you want to pour over. Hope it helps.

You learn SO much about a person from what he chooses to do when he thinks he's anonymous

I agree. How a person acts when they think they can get away with it says a lot about them.

I believe that meteorologists think that global warming might be a part of natural shifts in weather patterns. They might be right, I'm sure weather patterns change on their own, but it seems clear to me that humans are driving the most significant changes.

On the bright side the British made it clear to the UN that climate change is a key issue, especially over the next ten years. We can't afford to put this off any longer.

We've got to get back on track with the Kyoto protocol. According to the Economist EU countries and Japan will meet their goals, but the US and Canada won't. And things are going to get a lot worse if we don't act; China and India will overtake the US as the biggest producers of greenhouse gases, and they won't even think about slowing down unless the US does first.

When concerns about the economy trump the environment every election few politicians are willing to risk a drop in global output, even if realistic models put it at below 1%. Bottom line, there will have to be a major priority shift among voters for this to fly.
