Swift as the boreal light which flies, At midnight through the startled skies.

迅捷犹如扑面的灯火，掠过惊悚的星空夜半。

The boreal forest, also known as Taiga, is the largest terrestrial biome on the planet.

北针叶林也被称为泰加林，是地球上面积最大的陆地生群系。

Black spruce and fir are the dominant tree species in the boreal forest.

黑云杉和冷杉是北森林的优势树种。

Jill Johnstone has been studying boreal forest ecology for decades.

吉尔·约翰斯通几十年来研究北森林生。

Zephyr was a west wind but when you're talking about a north wind your speaking in boreal terms.

Zephyr指西风，而北风用boreal表示。

I'm walking my dogs through the boreal forest.

我带着我的狗穿过北森林。

When the boreal forest burns, it has the potential to release gigatons of carbon into the atmosphere.

北森林燃烧时，它有可能向大气中释放数十亿吨的碳。

The boreal forest is the largest terrestrial biome in the world.

北针叶林是世界上面积最大的陆地生群系。

This past spring, Randi Jandt and her colleagues published a paper in Nature about wildfires that overwinter in the boreal forest.

今年春天，Randi Jandt 和同事《自然》上发表了关于北针叶林越冬野火的文章。

They may be frightening and destructive forces of nature, but wildfires are also vital to the existence of healthy boreal forest ecosystems.

野火可能有点可怕， 并对大自然有破坏力，但它们对于维持健康的森林生系统却有着重要的意义。

The boreal forest is the largest terrestrial biome in the world. It covers 14 percent of the land on earth.

北森林是世界上最大的陆地生物群落。 它占地球陆地面积的14%。

But this feedback of vegetation change in the boreal forest is at least pushing back against that acceleration to slow us down.

但这种北森林植被变化的反馈至少会把加速的速度往回推，让我们减速。

This past spring, a group of scientists released their findings from a 15-year study that looked at how boreal forests regenerate after wildfire.

今年春天，组科家公布了他们对北森林野火后如何再生的15年研究的发现。

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

Johnstone 说这种新北针叶林存储碳的速度，是未过火时的4倍。

Wildfire is a normal part of the lifecycle for a boreal forest, but as the climate warms, this ecosystem is becoming increasingly vulnerable.

野火是北森林生命周期中正常的部分，但随着气候变暖，这个生系统变得越来越脆弱。

And what we're concerned about is that as far as climate warming leads to more fire weather, we get more severe and active fires burning in the boreal forest that releases more carbon.

我们担心的是，只要气候变暖导致更多的火灾天气，北森林的火灾就会更严重、更活跃，从而释放更多的碳。

In the last two fire seasons, other parts of the world dominated by boreal forest have also seen overwintering fires and Jandt says that may be where some of her research goes next.

过去的两个火灾高发季，北针叶林为主的其它地区已经出现了越冬火灾，Jandt 说她接下来可能去研究那些地。

Well, one of the things that we've been noticing in the past couple of decades is that fires are burning differently in the boreal forest than we understand them to have burned in the past.

过去的几十年里，我们注意到的件事是，北森林中燃烧的大火与我们过去所理解的不同。

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家担心北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”。
