Babbling brooks adding to climate change?



Studying stream bubbles isn’t exactly a walk in the park. What, with the mud and ticks, the long days hiking and swimming through mucky streams, the sun exposure and scratching brush.

But in the end, it may prove to be insightful. The bubbles coming from freshwater sources, new research suggests, may be a key and currently unaccounted for source of methane, the second-largest greenhouse gas contributor to human-driven global climate change.
