Since 1990, the Clean Air Act has reduced emissions of six common pollutants by 41%, but according to a handful of environmental groups, Pennsylvania is not doing its job when it comes to haze.

Earthjustice, on behalf of the Clean Air Council, the National Parks Conservation Association, and the Sierra Club, has filed a second lawsuit against the EPA for its approval of a haze plan that they say does not meet the requirements of the Clean Air Act.

DEP Urges EPA To Change Clean Air Act

The Pennsylvania Department of Environmental Protection (DEP) has proposed what it believes to be a “win-win” situation for the environment and existing power plants.

The DEP wants to make some changes to the New Source Review (NSR) provisions under the Clean Air Act.

Extreme weather, greenhouse gases, carbon monoxide and glacial melting; all these buzzwords have increasingly entered the public vernacular in the past 20 years. 

Following a UN report by the World Meteorological Organization, scientists expect that the topic of global warming and climate change will continue to be a hot issue.  The report, “The Global Climate 2001-2010: A Decade of Extremes,” cites that the past decade has seen an abundance of greenhouse gas emissions that has caused increased temperatures on both hemispheres, all oceans and an accompanying rapid decline in arctic sea ice and glaciers. 

Director of Science at the Carnegie Science Center, John Radzilowicz, has been following the topic of global climate change and was not necessarily surprised by the UN report.  He was optimistic, however, that the report was gaining attention and combined a multitude of data pointing to the extremes in weather conditions throughout the world.
