Weather chills March for Science Iowa turnout but can’t freeze plans to hold politicians accountable

By Thursday of last week, it was becoming clear that the 2018 version of the March for Science Iowa would suffer from the state’s bizarre spring weather. Over the previous few days, the forecasts sank from 60 degrees and sunny to the low 40s and rainy.

Organizers (including your correspondent) hung onto hope that the situation would change, but by Saturday morning it appeared almost certain to be a miserable day.

It wasn’t the best outcome, yet march leaders had already decided that the event’s purpose would endure past a single annual event. They’re determined to give voters the information they might have gotten had the event gone as planned.

Science marches on – with some conspicuous absences

Plans are shaping up for the 2018 version of the March for Science Iowa, a more overtly political version of last year’s event, when more than 3,000 Iowans flooded the Capitol grounds.

With elections coming up, organizers (including your humble correspondent) have invited candidates to appear on Saturday (the event starts with the march at around 1:00, followed by candidate forums and speeches at 2:00) to detail their views on publicly supported research, science education and evidence-based policy.

The march is nonpartisan: We want to hear from politicians and candidates from both parties. But it is not nonpolitical: We demand that our elected officials and contenders uphold science.

We invited candidates for governor, the Third Congressional District, agriculture secretary and secretary of state. Most will attend.

But only from one party. Guess which.

Cooler, wetter weather: Thanks, corn and beans … I think

About now, farmers in Iowa and across the Corn Belt get itchy. As the weather warms, they start tuning plows and planters, preparing to put another crop of corn and soybeans in the ground.

Within months, the rural Midwest will largely be a sea of towering stalks filling out ears and squat bean plants putting on pods.

But this sea of biomass has unforeseen effects on Midwestern climate, a study from the Massachusetts Institute of Technology suggests – and, I would argue, contributes to global climate change.

When you’re driving past those carpeted fields this summer, you can thank them for countering higher temperatures driven by greenhouse gas emissions, but curse them for more frequent drenching, violent thunderstorms and tornadoes.

It stands to reason that agriculture – which has never been more intense or widespread in human history – is doing something to our weather. But there are bigger questions about its impact.
