What Comes From Alaska & May Save Us All?


Oudemansiella_nocturnum.JPG No, not these miraculously fast fruiting bodies but these ones: mushrooms. That’s right. The fungi growing in the dry spruce forests of Alaska, Canada, Scandinavia and other northern regions are fighting global warming in unexpected ways. When temps rise and soils warm, fungi are not increasing the rate at which they convert soil carbon into carbon dioxide—as many feared. Instead they dry out and produce significantly less CO2.

Northern forests contain an estimated 30 percent of the Earth’s soil carbon. That’s equivalent to the amount of atmospheric carbon. Which means that mushrooms are not contributing to a vicious cycle of warming in dry boreal forests. Instead, they’re actually preventing further warming from occurring. Possibly giving us a teensy bit more time to implement responsible policies to counteract warming globally. . . Starting with responsibly electing the next president of the United States. The study, btw, appears in the journal Global Change Biology.

WE DON'T KNOW

What's going to happen next as the headlines grow crazier and more disconcerting by the day. But we do know the job of an independent, unrelenting press is more important than ever—and the ongoing commitment of MoJo readers to fight for a democracy where facts matter and all can participate is absolutely vital.

If you feel the urgency deep in your bones like we do, please consider signing up as a monthly donor during our fall pledge drive to support Mother Jones' fair and fearless reporting for the long haul (or make a one-time gift if that works better for you). The headlines may fade, but the need to investigate the powerful never will.
