Pennsylvania Congressman Scott Perry of the Fourth District rejects the
scientific fact of anthropogenic global warming. In a September 20, 2012
debate, then-candidate Perry (R-Penn.) said he “take[s] exception”
that global warming is “man-made” and is “concerned” that the “theory”
of global warming is not “proven.” His
comments
were transcribed by the York Daily Record’s Ed Mahon for the paper’s
political blog.
“I do believe global warming is occurring. …However, I do take exception, whether it’s man-made or not. I learned in public school, the scientific theory. …You have a theory and it has to be proven. And I’m concerned anytime that a nation, or the world, makes up policy based on a theory that … has gained consensus but” does not have proof, he said.
In reality, the carbon-dioxide greenhouse effect is a physical fact known since the 1800s. The only scientifically plausible systematic explanation – what the word “theory” means in scientific jargon, despite Rep. Perry’s confusion – for the rapid warming of the planetary climate since 1950 is industrial greenhouse pollution. Because of the hundreds of billions of tons of industrial carbon dioxide added to the atmosphere, the global climate is continuing to warm, with every decade since the 1970s warmer than the last, and the impacts of global warming are accelerating faster than scientists projected.
