Yes, a scam, right up there with the Great Depression, the Holocaust, and the Easter Bunny. I'm sure Mr. Powell has the education and credentials to back up his statement too, which goes against what 95% of climate researchers are telling us. But of course that's just a bunch of scientist talking and what have they done for us, besides giving us life saving vaccines, cures for many diseases, and countless inventions that have improved our lives? Compare these scientist with the Republicans who've recently given us two wars, the worst recession since the Great Depression (which of course was a hoax too!), and are dismantling a health care system which covers more Americans than at any other time in history!  

And then again, we should do as Mr. Fregger suggests and 'follow the money' though we only have to look to the White House to see where the big bucks lie (and I do mean lie).  Trump promised to bring our country together, but is instead selling it off to the highest bidders.
