red-rumped parrot 紅腰鸚鵡
emission 排放
Global warming is a big challenge for warm-blooded animals, which must maintain a constant internal body temperature. As anyone who’s experienced heatstroke can tell you, our bodies become severely stressed when we overheat.
全球暖化對溫血動物來說是一大挑戰，牠們必須保持穩定的內部體溫。任何經歷過中暑的人都會告訴你，當我們過熱時，我們的身體會感受到嚴重的壓力。
Animals are dealing with global warming in various ways. Some move to cooler areas, such as closer to the poles or to higher ground. Some change the timing of key life events such as breeding and migration, so they take place at cooler times. And others evolve to change their body size to cool down more quickly.
動物正在以各種方式應對全球暖化。有些會遷移到較冷的區域，例如更靠近兩極或是地勢較高的地方。有些改變關鍵生命事件的時間，如繁殖和遷徙，讓它們在較冷的時候發生。而其他透過演化來改變牠們的體型，以便更快地降溫。
Our new research examined another way animal species cope with climate change: by changing the size of their ears, tails, beaks and other appendages.
我們的新研究，考察了動物物種應對氣候變遷的另一種方式:透過改變耳朵、尾巴、喙以及其他附屬器官的大小。
We found most documented examples of shape-shifting involve birds – specifically, increases in beak size. This includes several species of Australian parrots. Studies show the beak size of gang-gang cockatoos and red-rumped parrots has increased by between 4% and 10% since 1871. We found clear evidence that birds with smaller beaks are also less likely to survive hotter summers.
我們發現大多數記錄在形狀的例子都涉及鳥類-特別是鳥喙尺寸的增加。這包含好幾種的澳洲鸚鵡。研究顯示，從1871年以來，紅冠灰鳳頭鸚鵡和紅腰鸚鵡的喙大小增加4%到10%。我們發現明確的證據顯示，喙較小的鳥類比較不可能在炎熱的夏天存活。
So while predicting how wildlife will respond to climate change is important, the best way to protect species into the future is to dramatically reduce greenhouse gas emissions and prevent as much global warming as possible.
雖然預測野生動物如何應對氣候變遷很重要，但保護物種可以存活到未來最好的方式，就是大幅減少溫室氣體排放，並盡可能防止全球暖化。
