I'm collecting a Mr Johnstone from the States.

我正在去接一位美国来的约翰·斯通先生。

Jill Johnstone has been studying boreal forest ecology for decades.

吉尔·约翰斯通几十年来一直在研究北方森林生态学。

And here's where Johnstone and her colleagues discovered an unexpected twist.

约翰斯通和她的同事在这里发现了一个意外变化。

Johnstone says the change in vegetation regime might help bring the system back into “control” —at least for a bit.

Johnstone 说植被组织的改变，有助于将系统恢复到“可控”状态——至少能控制一点点。

Johnstone says this new kind of boreal forest is storing carbon four times faster than it would have before it burned.

Johnstone 说这种新北方针叶林存储碳的速度，是未过火时的4倍。

The added carbon accumulation, as the forest regime regenerates and shifts from coniferous to deciduous trees-that's like putting the parking brake on while driving the bus, says Johnstone.

约翰斯通表示，随着森林环境更新，针叶树转变到阔叶树，增加的碳积累就像在驾驶公共汽车时踩刹车一样。

Ecologists like Johnstone have worried for years about the amount of carbon that could be lost to the atmosphere from wildfire in the boreal forest, because that could lead to what she calls a " runaway feedback loop with climate change."

多年来，像约翰斯通这样的生态学家一直担心北方森林野火可能会导致大量碳流失到大气中，因为这可能会导致她所说的“气候变化的失控反馈循环”。
