Questions abound

In your editorial "In Denial: A Fog of Misinformation on Warming Confuses Some" (Oct. 26), you indicated that 47 percent of Americans polled do not think evidence of global warming is irrefutable. Later you note that half of the public favors carbon emissions while still being "unsure of many aspects of the debate."

I would definitely say I'm part of both groups, even though you praise one group and criticize the other. PG, am I so ignorant? It's puzzling to me that it's so unbelievable to you that I might question the science that to this point has been anything but irrefutable regarding mankind's effect on the Earth's temperature. A couple of thousand years ago the leading evidence was irrefutable that the Earth was flat.
