January 5, 2010

Scientists met in Washington, D.C. recently to discuss how to deal with the effects climate change is already having on critical ecosystems.


Climate change today. I’m Bob Hirshon and this is Science Update.

At a series of meetings in Washington entitled Beyond Copenhagen, climate scientists discussed practical issues beyond agreements to limit carbon emissions. Steve Murawski is chief science advisor for the National Marine Fisheries Service.

STEVE MURAWSKI (National Marine Fisheries Service):
A lot of these climate oriented issues are happening right now. We’re starting to see major ramifications of the warming of the oceans as well as their increasing acidification.

He says fish stocks are already fleeing the warmer water by moving deeper and closer to the poles. Carbon gases are making the oceans increasingly acidic, harming corals and shellfish. And sea level rise and violent storms are destroying wetlands. So while nations work to limit greenhouse gases added to the atmosphere, scientists worldwide face a daunting task, dealing with global warming already underway.
