Global warming, pollution cuts have kicked up rainfall

The combination of warmer global temperatures in a decrease in air pollution has increased rainfall 3.4 millimeters per year, reports New Scientists. Less pollution means more sunlight is getting through to the Earth's surface (an average .21 watts per square meter to be exact). That combined with warmer temps mean more water is evaporating, thus the increased rainfall. And that's good.

The bad news: rainfall is not evenly distributed. "Local factors" like wind patterns have caused some places (like the southwest US and southern Asia) to get drier.

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
