Most news about ground-level ozone pollution focuses on its considerable impacts to human health. But there may be a far broader and potentially bigger story: Ground-level ozone pollution significantly impairs plants' ability to absorb CO2 - which in turn exacerbates climate change, reduces agricultural yields (think: food shortages), and damages ecosystems.

Hot on the heels of the announcement of EPA's controversial revised ground-level ozone standard, the agency is required by court order to release its proposal for a revised airborne lead standard no later than May 1, 2008. A final rule is required by Sept. 1, 2008.

A wet, snowy winter has set the table for spring flooding in much of the eastern US and a few western states. NOAA published a forecast on March 20, 2008, of the areas most likely to get swamped. Among the states at risk are "much of the Mississippi River basin, the Ohio River basin, the lower Missouri River basin, Pennsylvania, New Jersey, most of New York, all of New England, and portions of the West, including Colorado and Idaho."

In the past few years, there have been several instances in which disturbance of sites containing naturally-occurring asbestos, via construction or other land use changes, has posed a potential health threat. As one tool for reducing such problems, on March 13, 2008, USGS released its fourth in a series of reports on US sites with naturally-occurring asbestos, covering 121 locations in AZ, NV, and UT.
