Frank Smead makes a very bold assertion that man-made global warming is a scam. He is putting his own opinion up against that of the vast majority of climate scientists with volumes of evidence accepted by virtually all of the world's governments. Further, average temperatures continually increase, sea levels rise, glacial and polar ice is regularly melting, ice shelves collapse and extreme weather events become more prominent. Who should we believe, Frank and his skeptical colleagues, or the preponderance of scientific and observational evidence?
I wonder whether Frank has grandchildren to whom he will have to explain his contribution to leaving the planet in the sorry state it is developing into. Actually, I don't think many of us are off the hook on that one with our consumptive lifestyles.
