A deadlock over the issue of global warming has drawn the city of Seattle, 14 leading climate scientists and several groups of Native Alaskans to file a lawsuit against the Environmental Protection Agency (EPA).
Two of the plaintiffs, John M. Wallace and David Battisti, are UW atmospheric scientists.
The lawsuit aims to make the U.S. Supreme Court obligate the EPA to regulate automobile emissions and recognize how they contribute to global warming.
The scientists believe carbon dioxide released from vehicles needs to be regulated to slow down the effects of worldwide climate change.
The groups want the Supreme Court to reevaluate a 2005 federal appeals court decision that granted the EPA freedom to ignore the issue of climate change and dowplayed the link between carbon dioxide emissions and global warming.
