Impenetrably ignorant Republican Senate candidate Ron Johnson, last seen at LGF when he said global warming is caused by sunspots and CO2 is harmless because it’s “sucked down by trees,” has made the news again with another outburst of anti-science idiocy: Wis. US Sen. hopeful: Global warming ‘unproven’.

MILWAUKEE — Wisconsin U.S. Senate candidate Ron Johnson said Thursday that global warming was an “unproven” science that shouldn’t be used to dictate U.S. policies.

The Republican business owner said domestic efforts to reduce global warming would hurt American businesses and send jobs to countries that have fewer restrictions. Johnson said it would be irresponsible to build U.S. policy on the basis of unsubstantiated theories.

“The point is, because we’re not certain, because it’s not proven, the last thing we should do is penalize our economy,” he told The Associated Press during an interview.

“I’m not even sure if, if it were a fact, whether we could do anything about it anyway,” he added later.

“Idiocy” may be the wrong word for this kind of nihilistic ignorance; future generations are going to judge these right wing science deniers very harshly, when the consequences of their deceptions become apparent to all.
