Speakers at a climate-focused conference on Feb. 23-25 were generally upbeat about efforts the government, states, non-profits and corporations have been making to address climate change over the past decade.
Carol Browner, a former U.S. Environmental Protection Agency administrator, pointed to the nation's ability to improve air quality through the Clean Air Act, which was enacted in 1970. "It is because of government and the private sector working together that we have made the progress that we have made in terms of cleaner air and cleaner water," she said at the Climate Leadership Conference in Arlington, Va. "We've got to show people that there is a path forward."
