Para 1
CLIMATE CHANGE REQUIRES THE WORLD'S ATTENTION
（1.）We have known about climate change for decades. There is little doubt that Earth is getting warmer and warmer (see the graph). A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate.

There is little doubt that...
along with
provide evidence
a dramatic change
para 1
1.气候变化
2. 毫无疑问...
3. 和；连同
4. 提供证据
5. 一个巨大的变化
1. There is little doubt that Earth is getting warmer and warmer.
There is little/no doubt that... 几乎没有疑问的是……
There is some doubt whether ... 毫无疑问的是……
that引导同位语从句，解释说明doubt的具体内容
注意：doubt前有否定意义的词修饰时，其后的同位语从句由that引导；doubt前有肯定意义的词修饰时，其后的同位语从句由whether或if引导。
Para 2
（2）In 2013, a lot of people were shocked by a news photo of a dead polar bear that was found on Norway’s Arctic island of Svalbard. According to the scientists who found its dead body, all that remained of the polar bear was "skin and bones ". An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died. Experts claimed that low sea-ice levels caused by climate change meant that the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earth’s ecology.
be shocked by
appear to do =seem to do
in order to do...
the alarming case
have an impact/effect/influence on
para 2
1. 被...震惊
2. 似乎
3. 目的是
4. 令人震惊的案例
5.对...产生影响
2. According to the scientists who found its dead body, all that remained of the polar bear was “skin and bones”.
who引导的定语从句，修饰先行词scientists
that引导的定语从句，修饰先行词all, that不能用which代替
句意：根据发现北极熊尸体的科学家的说法，这只北极熊只剩下了“皮和骨头”。
3. …the bear appeared to have starved and died.
本句中appear是系动词，to have starved and died是不定式作表语。starve这个动作发生在appear之前，所以用完成式的形式来表达。
e.g. Thousands of people will starve if food doesn't reach there.
The schools are starving for funding.
starve to death 饿死
be starving of/for 缺乏/急需……
（3）Then what is causing the increase in the global average surface temperature Climate scientists often mention a key climate process called the "greenhouse effect " which has two common meanings: the "natural greenhouse effect and the "man-made greenhouse effect. The "natural "greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth's surface as short-wave radiation. The heat is released back into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earth's climate warm and habitable. Without this process, Earth could not sustain life. However, the "man-made greenhouse effect" has now become a big problem. When people produce huge amounts of extra greenhouse gases by burning fossil fuels, more heat energy is trapped in the atmosphere and causes Earth's surface temperature to rise quickly.

过去分词作后置定语，修饰名词process

句意：气候学家经常提到一个被称为“温室效应”的关键气候过程，它有两个常见的含义：“自然”温室效应和“人为”温室效应。
5. When people produce huge amounts of extra greenhouse gases by burning fossil fuels…
huge amounts of + 不可数名词 大量，许多
修饰名词作主语时，谓语动词用复数形式
a huge amount of +不可数名词 大量，许多
修饰名词作主语时，谓语动词用单数形式
eg A huge amount of money has been spent on this project.
eg Huge amounts of damage have been done in a short time.
（4）There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay. In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves causing deaths and economic losses。

eg The interview was broadcast live across China.
broadcast v. to tell sth. to a lot of people使广为传播，散布
eg Don’t broadcast the fact that he lost his job.
Para 5
（5）Continued greenhouse gas emissions will result in further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce our "carbon footprint" by restricting the amount of carbon dioxide our lifestyles produce. It is our responsibility to seize every opportunity to educate everyone about global warming, along with its causes and impacts, because this is the most serious issue affecting all of us on this planet. So what will you do to help

eg In future we will restrict class sizes to 20 students.
I'm restricting myself to a piece of candy a day.
省略了that/which的定语从句，修饰先行词carbon dioxide
10. It is our responsibility to seize every opportunity to educate everyone about global warming,…
seize vt. to take hold of something suddenly and violently 抓住
