Climatologists offer evidence – and encourage action – on climate change

When you want to learn about climate change, talk people who study climate.

SciLine, the science information service for journalists, did just that. As part of a science essentials boot camp for political reporters, the nonprofit (associated with the American Association for the Advancement of Science) gathered three state climatologists before a Science Center of Iowa audience earlier this month.

The climate mavens from Iowa, Nebraska and North Carolina were unequivocal in their assertion that man-made climate change is real. Doubts among the public, especially farmers, are fading as bouts of extreme weather become more common, they said.

The three experts varied somewhat, however, in their thoughts on how we should respond to the climate change threat. And it seemed to me that the discussion mostly missed the point in a substantial way.

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

Cornfields might not understand it, but they're messing with our weather.

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. Read the rest of this entry »
