The World Conference on Climate Change meets this month, once again sparking debate about whether global warming is a real and imminent threat to our existence. This Saturday on Up For Debate, Julie Roys will discuss the issue with eco-evangelical Rusty Pritchard, who believes in global warming — and Cornwall Alliance founder, Calvin Beisner, who’s a global warming skeptic. Is the sea level rising and threatening to flood the earth? Are greenhouse gases created by human activity to blame? Listen and join the discussion this Saturday at 11 a.m. Central Time on Up For Debate!
