OSHKOSH, Wis. (WTAQ) - Republican U.S. Senate candidate Ron Johnson says global warming is “unproven,” and it shouldn’t be used to set government policies.
The Oshkosh businessman first said in August that climate change was probably caused by sun spots or other natural variations. But he took a tougher stand yesterday, telling a media outlet there’s insufficient evidence that global temperatures are rising – and even if they are, he’s not sure people can do anything about it anyway.
NASA says the world’s average temperature has risen by almost 1.5 degrees in just over a century. And over 300 scientists in 48 nations cited 10 indicators in July which showed that global warming is undeniable.
But some scientists have disagreed – and Johnson says the dissent demonstrates his point that the science of global warming is unproven. The Senate remains deadlocked on smokestack emission limits, after the House approved them.
Johnson’s opponent, incumbent Democrat Russ Feingold, has said he favors climate change legislation. But Feingold opposes mandatory limits on greenhouse gas emissions because it would hurt states like Wisconsin which rely heavily on coal-generated power.
The proposals include tax hikes on larger polluters, but Johnson says now is not the time to raise taxes with the economy in such bad shape.
