A warming ocean and atmosphere along with① melting② ice and rising sea levels③ provide evidence of a dramatic change in the global climate.

UNIT 3　ENVIRONMENTAL PROTECTION 英语　选择性必修　第三册　R 返回导航 ❷that引导定语从句，先行词是a dead polar bear。 ❸all后接that引导的定语从句。 ❹appear后接不定式的完成式作表语。 UNIT 3　ENVIRONMENTAL PROTECTION 英语　选择性必修　第三册　R 返回导航 Then what is causing the increase in the global average⑫ surface temperature? Climate scientists often mention a key climate process ❺called the “greenhouse effect⑬”， which has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect.The “natural” greenhouse effect refers to⑭ the fact ❻that heat from the sun enters the atmosphere and warms Earth's surface as short­wave radiation．The heat is released⑮ back into space at longer wave lengths.Greenhouse gases in the atmosphere，such as methane and carbon dioxide⑯，trap some of the heat， UNIT 3　ENVIRONMENTAL PROTECTION 英语　选择性必修　第三册　R 返回导航 ❼keeping Earth's climate warm and habitable⑰.❽Without this process，Earth could not sustain⑱ life.However，the “man-made” greenhouse effect has now become a big problem.When people produce huge amounts of⑲ extra greenhouse gases by burning fossil fuels⑳，more heat energy is trapped in the atmosphere and causes Earth's surface temperature to rise quickly. UNIT 3　ENVIRONMENTAL PROTECTION 英语　选择性必修　第三册　R 返回导航 ❺过去分词短语作后置定语。 ❻that引导同位语从句。 ❼现在分词短语作状语。 ❽介词 without 可用于表示条件，引出虚拟语气，与 but for 大致同义，意为“若无；若非”，此处相当于If there were not this process。 UNIT 3　ENVIRONMENTAL PROTECTION 英语　选择性必修　第三册　R 返回导航 There is strong and comprehensive evidence ❾that 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. UNIT 3　ENVIRONMENTAL PROTECTION 英语　选择性必修　第三册　R 返回导航 ❾that引导同位语从句。 that引导宾语从句，此处that虽然在从句中不作成分，但不能省略，因为其后还有一个if引导的条件状语从句。 UNIT 3　ENVIRONMENTAL PROTECTION 英语　选择性必修　第三册　R 返回导航 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?
