I guess they're not really worried that CO2 will cause their children to die with kidney stones and AIDS during fiery floods: Iowa Senate has their "once a year" debate on climate change; most of them laugh when it's over

State senators disagree over “climate change” (audio)

That prompted Republican Senator David Johnson of Ocheyedan to ridicule the idea that humans are the main cause of climate change.

“With all due respect to our religious leaders…how much are you willing to spend to reverse what you call global warming?” Johnson asked. “…The country of Spain made a huge transition to their economy for green energy. What was the result of that? Bankruptcy?”

...At the mid-way point Senate President Jack Kibbie called the 40-minute episode a “wonderful discussion” about climate change. Near the end, Senator James Seymour and Kibbie joked about their looming retirement from the senate.“This has been a great debate this morning and I suspect, Mr. President, you — like myself — are going to miss this place terribly,” Seymour said, as most in the senate began laughing. Kibbie laughed heartily, too, and his chuckles were amplified because he laughed right into his microphone.

Others like Republican Senator Randy Feenstra of Hull suggested it was time for legislators to quit talking about climate change and move on to more productive tasks.
...“Once a year we do this,” Feenstra said of the Iowa Senate’s climate change debate.
