According to a more report conclusive from the Intergovernmental Panel on Climate Change, and internationally renowned climatologist, Dr. Raymond Bradley, global temperatures have risen rapidly in the last 100 years, especially in the last 50 years. Experiments have also proven that greenhouse gases do create more heat in the atmosphere.

In addition to raising temperatures, greenhouse gases change precipitation patterns, meaning some areas that usually have heavy rainfall experience dry spells, and other areas get extremely heavy rainfall. Bradley says these effects will continue to occur more often if greenhouse gases continue to fill the atmosphere.

Before exploring the issue of creating green jobs in the 21st century economy, Essential Pittsburgh took the time to air some answers to environmental questions from listeners.

In response to a question on why the energy conversation won't embrace the possibility of more drastic advances in alternative energy such as nuclear fusion, James Clad, a consultant and distinguished research fellow at the National Defense University acknowledged that the energy conversation had been turned into a one note discussion on fossil fuels. 

"The energy world is defined by oil and gas and everything else is just an add on." said Clad

United Nations Report Examines "Climate Extremes" Over Past Decade

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.
