But none of this works unless the energy balance is in check.

但除非能量平衡得到控制，否则这一切都无效。

Having less weight to shift, they may be able to run for longer before the energy balance tilts against them.

其体重轻，跑动快，相比于成年熊，它们可以奔跑的时间更长。

And we expect that energy balance to match.

我们期望能量平衡能够匹配。

In general, changes in climate occur when the energy balance of the Earth is disturbed.

一般来说，当地球的能量平衡被打破时，气候就会发生变化。

Since no one burns the same exact number of calories that they eat every day, the key is to maintain energy balance over the long term.

因为没有人每天卡路里的摄入与消耗恰好相等，所以关键是要长远地保持能量平衡。

And these are super abstract things that, you know, when you read a biology textbook, you don't remember the words, but you start, you know, what's mitochondria, what are organelles, what's the energy balance.

这些都是超级抽象的东西，你知道，当你读一本生物学教科书时，你不记得这些词，但你开始，你知道，什么是线粒体， 什么是细胞器，什么是能量平衡。

But the modelling suggested that such drastic changes in the energy balance in the upper atmosphere could play havoc with tropical monsoons, the seasonal rains on which the agriculture and economy of many countries depend.

但模型表明， 高层大气能量平衡的这种剧烈变化可能会对热带季风造成严重破坏，热带季风是许多国家农业和经济所依赖的季节性降雨。

Mr. Cayan says heat-trapping greenhouse gasses are causing temperatures to rise. " Sea level rise will not end in 2100. It's an ongoing problem, as the planet adjusts to a new, essentially a new energy balance because of greenhouse gases."

Cayan 先生说，吸热的温室气体正在导致温度升高。 “海平面上升不会在 2100 年结束。这是一个持续存在的问题，因为由于温室气体，地球正在适应新的、本质上新的能量平衡。”
