I believe Global Warming to be a fact. Here in Hilo, HI there's a volcano, Mauna Kea, that used to have snow every winter. There's been no snow for the last 6 or 7 years, except for the occasional winter storm that blows through.
The winters have been warmer and the summers hotter and drier, especially during El Nino years.
What I don't believe, and I don't believe that science has proved, is that Global Warming is a man-made phenomenon. And it's that fact that the leftist media, the U.N., and the enviro-whackjobs constantlly get wrong.
My teachers in the 60s (grammer and high school) taught us that we were coming out of an ice age that that climate would get warmer. Maybe they were correct...
