And scientists now think that this climate shift had effects far away-including causing a megadrought in Southeast Asia.

科学家现在认为，这种气候变化产生了深远的影响，包括在东南亚造成特大干旱。

Ancient climate shifts might've had something to do with it.

古代气候变化可能与此有关。

Dr. Posth speculated that another climate shift could explain this new wave.

波斯特博士推测，另一次气候变化可以解释这一新浪潮。

Species are sometimes introduced into new habitats through natural factors, like storms, ocean currents, or climate shifts.

Professor: Well, yeah, considering that other climate shifts take thousands of years, this one is pretty abrupt.

教授：嗯，是的，考虑到其他气候变化需要数千年，这个变化非常突然。

But as Antarctica drifted towards the South Pole and the levels of CO2 in the atmosphere decreased, global climate shifted from greenhouse to icehouse conditions.

As the climate shifted, more productive environments with more food began to take shape closer to the poles, so whales started to spend a lot more time there and became more migratory.

随着气候的变化，更多的食物开始在靠近极地的地方形成更多产的环境，所以鲸鱼开始在那里花费更多时间，并开始更多得迁移模式。

Over the last 100,000 years of the Ice Age cycling, we have had a couple dozen of these large,abrupt, widespread climate shifts, almost as if the Earth was bungee jumping off the climate roller coaster.

在过去 100,000 年的冰河时代循环中，我们经历了几十次这样大范围的、突然的、广泛的气候变化，几乎就像地球在气候过山车上蹦极一样。

We listened to them, but we also listened to other facts and arguments: the large international support to the Paris Agreement, science with robust data, and more data every year, the evidence of climate shifting all around us.

我们听取了他们的意见， 但我们也听取了其他事实和论点： 国际社会对《 巴黎协定》 的大力支持、我们周围气候变化的证据。
