Ah, those crys­tal-clear moun­tain streams. Turns out they emit a lot more CO2 than expect­ed. The pre­vail­ing the­o­ry is that, despite pick­ing up less car­bon as they flow, moun­tain-streams’ tur­bu­lence means they “exchange gas with the air more quick­ly than placid streams do.”

In fact, in their study “The team found that by area, most moun­tain streams were net sources of CO2.”

Next up: How will this affect cli­mate and car­bon models?
