EPA is scheduled to announce by March 12, 2008, its final rule for a new ground-level ozone standard, last updated more than a decade ago.
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.
