An almost nuclear winter had arrived.

一个近乎核武器的冬天已经到来。

Or the black rain of a nuclear winter.

或是核冬天的尘雨所带来的窒息般的袭击。

But why should I worry about nuclear winter when nobody in their right mind would ever start a nuclear war?

但既然头脑正常的人都不会发动核战争，我为什么要担心核冬天呢？

The ozone would be depleted, we'd have acid rain but we'd also have flash burns, incineration of vegetation, perhaps something resembling nuclear winter.

臭氧层将被消耗尽，我们（的地球）就会有酸雨，就会有光辐射烧灼，植被焚化，或许就类似核冬天。

But if there's ever a nuclear war that's larger, the ensuing nuclear winter might be even more devastating.

但如果发生更大规模的核战争，接下来的核冬天可能更具破坏性。

Consideration of the impact of nuclear winter or searching for possible Earth-impacting asteroids would not have occurred if we were ignorant of past biological catastrophes.

如果我们不了解过去的生物灾难，就不会考虑核冬天的影响或寻找可能撞击地球的小行星。

Researchers suspect that the impact caused the extinction by kicking up a cloud of dust and tiny droplets called aerosols that plunged the planet into something like a nuclear winter.

研究人员怀疑，撞击是由一团被称为气溶胶的尘埃和小水滴组成的云引起的，这些云使地球突然进入了类似核冬天的状态。

We also can't say for sure whether a global nuclear war would cause a nuclear winter so severe it would pose an existential threat to humanity.

我们也不能确定全球核战争是否会导致严重的核冬天，以至于对人类的生存构成威胁。

A portion of the particles will flow to the edge of space for years and cause a nuclear winter that could lower global temperatures by a few degrees for a few years.

一些粒子则会留在大气边界，导致“核冬天”，几年之内，地球上的气温都会下降几度。

And during the nuclear winter that follows, 75% of species — plant and animal — are wiped from the face of the Earth, including the largest creatures ever to walk on its surface.

在随之而来的核冬天里，地球上 75% 的物种——植物和动物——都被消灭了，包括有史以来在地球表面行走过的最大生物。

Crypto is kind of like a cockroach in that it's very hard to kill. It's immune to the nuclear winter of a crash like we're currently seeing in crypto.

加密货币有点像蟑螂，很难杀死。它不受我们目前在加密货币中看到的崩溃的核冬天的影响。

The resulting fallout--massive wildfires, tsunamis, and a " nuclear winter" effect caused by the dust and soot blocking out the sun--created a hostile environment where many species could not survive.

由此产生的后果——大规模野火、海啸，以及灰尘和煤烟遮挡阳光造成的“核冬天”效应——造成了许多物种无法生存的恶劣环境。

Very rough guesses put the risk of existential catastrophe due to nuclear winter and climate change at around 0.1%, with the odds of a pandemic causing the same kind of collapse at a frightening 3%.

粗略估计，生存灾难的概率关系到核冬天和气候变化在 0.1% 左右，而一场疾病大流行导致类似灾难的概率是可怕的 3%。

I think that crypto is kind of like a cockroach in that it's very hard to kill, it's immune to the kind of the nuclear winter of a crash like we're currently seeing in crypto.

我认为加密货币有点像蟑螂，因为它很难杀死，但是它又对我们目前在加密货币中看到的核灾冬季免疫。

A 1 km asteroid strikes Earth about every half million years, and anything larger could put enough dust into the atmosphere to cause long-term climate change … nuclear winter, asteroid edition.

大约每 50 万年就有一颗 1 公里长的小行星撞击地球，任何更大的小行星都可能将足够多的尘埃带入大气层， 导致长期气候变化… … 核冬天，小行星版。

Most recent work on the atmospheric effects of nuclear war support the earlier models of nuclear winter and prolonged reduction in sunlight that would lead to massive starvation, billions of deaths.

最近关于核战争对大气影响的研究支持早期的核冬天模型和阳光的长期减少，这将导致大规模饥饿和数十亿人死亡。

One thing that's different from historic collapses is that humanity now has unprecedented destructive power: Today's nuclear arsenals are so powerful that an all-out global war could cause a nuclear winter and billions of deaths.

和以往历史崩溃不同的地方是，人们今天有空前的破坏力：今天的核武库如此强大，一场全面的全球战争可能导致核冬天以及数十亿人口死亡。

Because of all the ash and ejecta that was pumped into the atmosphere from the crash, the earth would enter into a deep years-long nuclear winter where temperatures around the world would be freezing without any other seasons.

由于所有的火山灰和喷射物因为撞击被泵入大气层，地球将进入漫长的含核冬季，世界各地的温度将达到冰点，没有任何其他季节。

In fact, crops are going to have a really hard time because there will be less rain during a nuclear winter and there will be less time for the crops to grow because of killing frosts.

事实上，农作物将很难过，因为在核冬天，降雨量会减少，而且由于致命的霜冻，农作物的生长时间也会减少。
