1
Climate change has become a huge issue lately, to the point where it's not only rocking the world of science, but politics as well.
2
Yet, many people are still unaware of what climate change is and what some of the potential implications are.
3
So, in this video, we'll be going over the basic concept of climate change.
4
The sun's rays take roughly 8 minutes to travel that 93 million mile distance to Earth, where it will light up our beautiful skies.
5
The thing is that the sun doesn't just release those golden rays of light we see in the morning.
6
It releases radiation in other parts of the electromagnetic spectrum, like UV or the infrared radiation we feel in the form of heat.
7
Sometimes the emitted infrared radiation will be reflected back into space when it hits
8
Earth, but other times that reflected infrared radiation can be trapped by a layer of gas in our atmosphere called greenhouse gases,
9
which typically consist of water vapor, methane, nitrous oxide and most infamously carbon and carbon dioxide.
10
Imprisoned by that pesky greenhouse gas the infrared radiation has nowhere else to go
11
and remains on earth where it begins to heat up the planet, a phenomena we have come to call global warming.
12
Global warming can have many implications.
13
For example, it can melt glaciers which can result in sea levels rising.
14
It can also cause more evaporation leading to more precipitation
15
which can change the weather patterns in certain areas causing to become wetter or drier.
16
This This change in overall weather patterns in certain regions is called climate change.
17
Climate change isn't just wreaking havoc via droughts and rising sea levels.
18
In Siberia, for example, the permafrost is now thawing out and may potentially release many bacteria and viruses that are trapped inside.
19
Of course, that's just one of the many problems we're facing now.
20
In our climate change series, we'll be taking a look at the more complicated consequences of climate change,
21
as well as some of the solutions scientists are working on to give our blue rock a second chance.

需要注意的發音
說話人用了 6 次縮略和弱讀形式，例如 we'll, doesn't, don't。請按聽到的簡短形式來說。
- “th” 音: methane /ˈmiːθeɪn/, thaw /θɔː/
- “sh” 和 “zh” 音: radiation /ˌɹeɪ.diˈeɪ.ʃən/, implication /ˌɪmpləˈkeɪʃən/, potentially /pəˈtɛnʃ(ə)li/, precipitation /pɹɪˌsɪpɪˈteɪʃn̩/, glacier /ˈɡleɪ.ʃɚ/
- 長單詞——注意重音位置: radiation /ˌɹeɪ.diˈeɪ.ʃən/, implication /ˌɪmpləˈkeɪʃən/, complicated /ˈkɑm.plɪˌkeɪ.tɪd/, potentially /pəˈtɛnʃ(ə)li/, phenomenon /fəˈnɒm.ɪ.nən/
中文母語者容易讀錯的音：

- 詞尾子音 — 要讀清楚，後面不要加母音: infrared /ˌɪnfɹəˈɹɛd/, reflect /ɹɪˈflɛkt/, trap /tɹæp/, greenhouse /ˈɡɹːnˌ(h)aʊs/, complicated /ˈkɑm.plɪˌkeɪ.tɪd/

- 錄下自己的聲音並與原聲對比，特別注意 radiation, infrared, reflect 這類單詞。
什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
