What cnsequences may the climate change cause?
Befre yu read，lk at the graph and the picture belw and discuss these questins in grups.
1 What is the graph abut? What infrmatin can yu get frm it?
The graph shws the change in the Glbal Surface Temperature between 1920 and 2016. It shws the temperature anmaly，which shws hw much the temperature has risen abve what it wuld usually be at a base level.
2 Have yu ever seen the pht befre? What might be the stry behind it?
I haven’t seen this pht，but I have seen phts like it. The stry is that theplar bear starved t death because it culd nt find enugh t eat.
1 What happened t the plar bear in the pht? Why did the writer write abut it? 2 Why is the “natural” greenhuse effect imprtant and necessary?
Read the text and answer the questins.
The plar bear in the pht died f starvatin. The writer wrte abut it because it shwed ne f the effects f rising temperatures due t climate change.
The “natural” greenhuse effect is imprtant because it warms the Earth’s surface and keeps it habitable.
3 What are the cnsequences f high greenhuse gas emissins?4 Why did the authr mentin the climate scientists’ warning?5 What is the authr’s purpse f writing this text?
High greenhuse gas emissins lead t mre heat energy being trapped in the atmsphere and rising temperatures.
The authr mentined the climate scientists’ warning because it is essential that we take actin and s it needs t be brught t everyne’s attentin.
The authr’s purpse is t infrm the readers and inspire them t d whatever they can t deal with this prblem.
CLIMATE CHANGE REQUIRES THE WORLD’S ATTENTION
CLIMATE CHANGE REQUIRES THE WORLD’S ATTENTIONWe have knwn abut climate change fr decades. There is little dubt that Earth is getting warmer and warmer（see the graph）. A warming cean and atmsphere alng with melting ice and rising sea levels prvide evidence f a dramatic change in the glbal climate. In 2013，a lt f peple were shcked by a news pht f a dead plar bear that was fund n Nrway’s Arctic island f Svalbard. Accrding t the scientists wh fund its dead bdy，all that remained f the plar bear was“skin and bnes”. An expert wh has studied plar bears fr many years said that frm the psitin f its dead bdy，the bear appeared t have starved and died. Experts claimed that lw sea-ice levels caused by climate change meant the bear culd nt hunt seals as befre，s it had t travel greater distances in rder t find fd. This alarming case shwed hw the increase in temperature had an impact n Earth’s eclgy.
Then what is causing the increase in the glbal average surface temperature? Climate scientists ften mentin a key climate prcess called the“greenhuse effect”，which has tw cmmn meanings：the “natural” greenhuse effect and the “man-made” greenhuse effect. The “natural”greenhuse effect refers t the fact that heat frm the sun enters the atmsphere and warms Earth’s surface as shrt-wave radiatin. The heat is released back int space at lnger wave lengths. Greenhuse gases in the atmsphere，such as methane and carbn dixide，trap sme f the heat，keeping Earth’s climate warm and habitable. Withut this prcess，Earth culd nt sustain life. Hwever，the“man-made”greenhuse effect has nw becme a big prblem. When peple prduce huge amunts f extra greenhuse gases by burning fssil fuels，mre heat energy is trapped in the atmsphere and causes Earth’s surface temperature t rise quickly. There is strng and cmprehensive evidence that the rise in temperature has led t an increase in extreme weather and natural disasters wrldwide，nt nly causing serius damage，but als csting human lives. Climate scientists have warned that if we d nt take apprpriate actins，this warming trend will prbably cntinue and there will be a higher price t pay. In fact，news reprts are frequently bradcast abut extreme rainstrms and heatwaves causing deaths and ecnmic lsses.
Cntinued greenhuse gas emissins will result in further warming and lng-lasting changes t the glbal climate. This requires the attentin f peple all ver the wrld. Gvernments need t cnsider making plicies and taking apprpriate actins and measures t reduce greenhuse gas emissins. We as individuals can als reduce ur“carbn ftprint” by restricting the amunt f carbn dixide ur lifestyles prduce. It is ur respnsibility t seize every pprtunity t educate everyne abut glbal warming，alng with its causes and impacts，because this is the mst serius issue affecting all f us n this planet. S what will yu d t help?
