Radio Smart Talk for Friday, June 7:

Dr. Michael Mann, one of the world's renowned climate scientists, will appear on Friday's Radio Smart Talk. 

Last month, the National Oceanic and Atmospheric Administration reported that the amount of carbon dioxide in the Earth's atmosphere had passed 400 parts per million on average.  Scientists have long viewed that as a milestone on the way to a warmer climate.  To put the reading into context, scientists said it could be the highest level of CO2 in the air in three million years -- even before humans evolved.

It also left many in the science and environmental communities saying steps being taken around the world to reduce the burning of fossil fuels are not having as much impact as needed to cut CO2 levels.

Dr. Mann will explain how the Earth could be affected by the rising carbon dioxide levels and if there still is time to reverse climate change.

    Can those who believe man is responsible for the increase in our air temperature state with absolute certainty that the temperature of "space" surrounding earth has not fluctuated over the past (blank) thousand years? Also, can they state with absolute certainty that the BTU output of the sun has not fluctuated over the past (blank) thousand years?

    If Pennsylvania were to suffer a severe drought.
    Given our vast woodlands.
    I believe our forest fighting resources would be stretched with all of our rural development.
    However with all of the gas sites, have they been factored in the staffing and cost to protect them from a spreading fire.
    Are there safety protocols,do the drilling companies gave their own staff.
    With climate change I'm afraid this day will come.

    I am not convinced. I do believe there is climate change is real, but there are so many"henny pennys" droning on from their respective ends of the argument of what is causing it that it is impossible to understand what is really going on!
