Moniz: Mother Nature could persuade climate change deniers; will it be in time?

For a while now, I’ve puzzled over something: Why does a segment of the population – and an even larger portion of Congress – disavow the evidence for anthropogenic (human-caused) global climate change?

Weather records show temperatures are increasing, with each year seeming to set a new record. Oceans are rising. Violent storms, droughts, wildfires and other weather-driven phenomena are happening more often and with greater force. Scientists who study the climate overwhelmingly agree we’re changing the atmosphere for the worse.

So why do so many people deny the evidence? And, more importantly, how do we change people’s minds and get them to take action before it’s too late?

I don’t have many answers and my small forum can’t do much to correct the situation, but last week I talked to someone who does have answers – and the power to do something about it.

When U.S. Energy Secretary Ernest Moniz came to Iowa, I got a moment to ask him about this. While his answer was reasonable, it was a bit disappointing.

Those wild and crazy snails are back, with lessons about sex

 In a study involving multiple generations of a freshwater snail in New Zealand, researchers at the University of Iowa found that polyploidy doesn't appear to be an asset—nor is it a drawback—for females bearing offspring without the help of a male. Instead, it's the snails' sexuality that creates the advantage: Asexual females, the study found, grew twice as fast during the late juvenile phase and reached reproductive maturity 30 percent faster than female snails that mated with males.

The snails are back. Or more precisely, researchers using snails as a model to understand the biological benefits of sexual reproduction are back with results.

I wrote about the research about two years ago, when conservative news outlets began ridiculing an $876,000 National Science Foundation grant to study “snail sex.” Two University of Iowa researchers, Maurine Neiman and John Logsdon, were among those receiving the grant.

Although multiple conservative outlets had reported and commented on the grant, none had asked the researchers to explain its significance. I was the first writer to contact them for any more than a cursory question. To me it was an example of a gap in science reporting in Iowa and conservative bias against government spending.

The bottom line: The tiny New Zealand snails are good models to study the evolutionary benefits of sexual reproduction, the true purpose of the study. The snails, Potamopyrgus antipodarum, have two genetic lines, one that reproduces sexually and another asexually, allowing the scientists to compare their genes for signs of advantages or disadvantages to sex.

Now results are coming out of this and related snail research, and the results are surprising. Sex and its biology, it turns out, aren’t as simple as scientists thought.

Ernest Moniz is coming to Iowa next month. Here’s why you should care.

I’m not a fan of Bill Nye. I certainly endorse his science advocacy and education efforts, but he’s of my sons’ generation, not mine, and his lack of deep academic credentials leaves him open to the kind of challenge Sarah Palin recently made. (I’m not saying Bill Nye isn’t a scientist, as Palin did. I’m saying there are other science spokespeople with stronger resumes and greater accomplishments.) So I didn’t make a big deal out of Nye lecturing at Drake University April 14.

But I am excited about the pending visit of a real science superstar: U.S. Energy Secretary Ernest Moniz. He’s coming to Ames on Friday, May 6 to speak at the dedication of the Ames Laboratory’s Sensitive Instrument Facility. (I wrote about the SIF and the high-tech tools it houses earlier this year.) He’ll stay overnight and deliver the undergraduate commencement address at 1:30 p.m. in Hilton Coliseum on Saturday, May 7.

It’s exciting because, as I’ll explain, Moniz is probably the most consequential energy secretary in history – a big influence on world peace and climate stability.
