A Simple Question For Climate Alarmists
earth burning up“What physical evidence supports the contention that carbon dioxide emissions from burning fossil fuels are the principal cause of global warming since 1970?”
(Remember back in the 1970s, climate scientists and media were predicting a return to an “ice age.”)
I have posed that question to five “climate scientist” professors at the University of Arizona who claim that our carbon dioxide emissions are the principal cause of dangerous global warming.
Yet, when asked the question, none could cite any supporting physical evidence.
Some of the professors would claim that computer models, when corrected for natural variation, required carbon dioxide emissions to correlate with observed warming of the late 20th century.
