1、 1 1One of the effects of global warming is the destruction of many important and erratic climate conditions will put our ecosystems to the test,the increase in carbon dioxide will increase the problem.The evidence is clear that global warming and climate change affects physical and biological syste
2、ms.There will be effects to land,water,and life.Already today,scientists are seeing the effects of global warming on coral reefs,many have been bleached and have died.This is due to warmer ocean waters,and to the fact that some species of plants and animals are simply migrating to better suited geog
3、raphical regions where water temperatures are more suitable.Melting ice sheets are also making some animals migrate to better regions.This effects the ecosystems in which these plants and animals live.Several climate models have been made and they predict more floods(big floods),drought,wildfires,oc
4、ean acidification,and the eventual collapse of many ecosystems throughout the world both on land and at sea.There have been forecasts of things like famine,war,and social unrest,in our days ahead.These are the types of effects global warming could have on our planet.2 Another important effect that g
5、lobal warming will bring is the loss and endangerment of many species.Did you know that 30 percent of all plant and animal species alive in the world today are at risk of extinction by the year 2050 if average temperatures rise more than 2 to degrees Fahrenheit.These mass extinctions will be due to
6、a loss of habitat through desertification,deforestation,and ocean warming.Many plants and animals will also be affected by the inability to adapt to our climate warming.Some species will survive though because they will migrate to other parts of the world where they can survive.A good example of tha
7、t happening is the red fox that has already done it.The red fox used to live mainly in North America,but has migrated now to the Arctic.People like you and me are also in danger,people living in coastal areas will be badly hit if sea levels rise.Desertification will also be a problem for humans,food
8、 may become scarce.3One very disappointing effect of global warming is war and conflicts.With a decline in the amounts of quality food,water,and land,it could bring an increase in global security threats,and war.Take the country Sudan for example,in that region global warming has played an important
9、 role.There is conflict in Sudan,global warming is not the only cause,but it has played its part.The roots of the problem in Sudan can be traced back to climate change,and the scarcity of natural resources.The conflict in Sudan started during a time of intense drought.Scientists and military analyst
10、s are predicting that climate change and the devastation it causes could bring war and conflict.When sufficient amounts of water and food are running short that is when war can come about.What this brings to light is the fact that ecological crisis and violence are both linked.4Economic calamities a
11、re another effect that global warming could bring.Take hurricane Katrina for example,one thing that climate change does is that it brings us more extreme storms like Katrina.Hurricane Katrina resulted in millions and millions of dollars in damage.When severe storms and floods occur,crops,homes,1 bus
12、inesses,and more all fail,and that costs a lot of money,and it hurts the economy.When severe floods occur you also need to make sure that the threat of disease is controlled.Hurrican Katrina resulted in 135$billion in property damage.That really hurt the economy that year.When severe weather does da
13、mage it can also raise the price of insurance,and this hurts the everyday person.Cleaning up a disaster area also costs a lot of money.If too many extreme storms hit in a certain time frame the impact on the economy can be disastrous.5 Drought is an effect of global warming that we are already seein
14、g right now.Many countries are finding that they are currently receiving more storms and rising waters,while other countries are suffering from drought.As the climate of the Earth warms,experts from Scientific American predict that drought conditions could increase by as much as 66 percent.Drought w
15、ill mean a shrinking water supply and a decrease in crops.Drought can mean a danger for global food production and supply.This also mean that several countries experiencing drought could have a major famine on their hands.Currently,India,Pakistan,and some parts of Africa are already experiencing dro
16、ughts.It is sad to say but experts are predicting that it will get much worse.One important effect global warming is having on our planet,is that it is producing more intense storms and floods.When you look at the scientific data concerning storms and floods in the last 30 years,you will see that ca
17、tegory 4 and 5 hurricanes have nearly doubled in occurence.What many people dont know or realize is that warm waters give hurricanes their strenght and power.Many scientists today are associating the increase in ocean and atmospheric temperatures to the rate of violent storms.Between the years 1905
18、and 2005 the frequency of hurricanes has been on the rise.From 1905 to 1930 there were an average of hurricanes per year,between 1931 and 1994,and between 1995 and 2005.In 2005 there was a record number of tropical storms that came about,and in 2007 the worst flooding in 60 years hit Britain.More re
19、cently,Australia has seen the worst flooding they have had in a long time.6 Heat waves are also an effect of global warming.It is no secret that temperatures are breaking records in the US and Canada and abroad.More extremely hot summer days are in store for North America and elsewhere if global war
20、ming continues unabated.Here are some heat waves facts for you:air pollution in urban areas could get worse with the increased heat.This could result in more people having heart attacts,strokes,and asthma attacks.Children,the elderly,poor,and people of color are more vulnerable to the effects of a h
21、eat wave.Scientists have confirmed that the frequency and duration of heat waves has definitely increased by a lot over the last 50 years.7 One obvious effect of global warming is the shrinking of glaciers,this is happening wherever there are glaciers worldwide.Mountain glaciers have been in retreat
22、 for a long time now as global warming continues to effect us.What many people dont realize though is that it is happening more rapidly now then previously believed.Glaciers dont only recede they also shrink vertically.The lakes this melting produces can also lead to more melting.These lakes are lik
23、e a cancer that is consuming our worlds glaciers.Here is a fact that may surprise you:Even if 1 all the worlds mountain glaciers were to melt,the effect on sea levels would be small.However,the disappearance of mountain glaciers would have other impacts on nature aside from raising sea levels.8Globa
24、l warming will also bring a rising of sea levels around the world.As glaciers and polar ice sheets melt,the sea levels will rise more and more,and the sea temperatures will also warm.This means more hurricanes,and more flooding due to the rise of the sea level.The Effects of Global Warming Nowadays,
25、our world is becoming hotter and we called it“Global Warming”which is to describe the rise of Global Warming has two sides of effect to the worlds,the Global Warming means there is more carbon dioxide in our some plants can grow faster and stronger than is its good on the other hand,the Global Warmi
26、ng will bring us more disasters than of the more and more carbon dioxide in the atmosphere,the earths temperature is rising day by high temperature will cause many serious the ice of Antarctica and Arctic Ocean begin to that happen,the height of sea level will some terrible disasters will coming,lik
27、e tsunami and so some countries,for example like Japan and some coastal cities will be submersed.One reason of Global Warming is that too much industrial emissions and poisonous gases which were made by human beings vented to our methane and carbon gases make the temperature rise day afteer that wil
28、l cause many natural tsunami,flood,drought and so on.Finally,if we dont stop,the world will become a death world without fate will like the main reason of Global Warming is the fast growing of the worlds if we dont control the speed of growing population,the situation will be worse.So is it already
29、too late to prevent the Global WarmingI think it is still not too we plant more trees,produce less greenhouse gases like methane and carbon dioxide,and to control the growing of situation of Global Warming will be we must to do it first in our daily to work by bus or on foot I think,is the best way
30、to prevent the worse situation of Global Warming.全球气温变暖的主要原因：人类活动对气候变化肯定是有变化和影响的。人类燃烧煤、油、天然气和树木，产生大量二氧化碳和甲烷进入大气层后使地球升温，大气中二氧化碳排放量增加是造成地球气候变暖的根源。The main reason for global warming:human activities definitely have an impact on climate change.Human burns coal,oil,natural gas which produced a large amou
31、nt of carbon dioxide and methane,and it warmed the earth.The cause of global warming is the increased carbon dioxide emissions into the atmosphere.造 成的危害:首先是自然生态会发生变化；土地荒漠化，森林退向极地，雨量增加，冬天更湿，夏天更旱，旱涝灾害增加，热带将酷热无比，人类难以生存。其次是两极冰块大面积熔化，使海平面上升，那将使生活在沿海的占世界 1/3 的人口无家可归，世界许多港口 1 城市 淹没于一片汪洋之中。Harms:first,to c

42、 affect the safety of the Qinghai-Tibet Railway.人们过去一向认为，多种植树木有助于减缓全球气温升高的现象。不过，科学家如今指出，如果地球气温再升高 2 摄氏度，森林反而可能成为二氧化碳的净排放来源。植物会吸收也会排放二氧化碳；健康的森林，尤其是热带地区的森林所吸收的温室气体，会比它们排放的来得多。不过，如果这些森林受到破坏、生病或是死亡，蓄积在这些森林里的二氧化碳就会被释放出来。人 类砍伐森林时进行的焚烧和摧毁所释放的温室气体，占了总碳排放量的 20%森林可吸收四分之一的总碳排放量，随着它们日益消失，或是成为净排放来源，空气中的二氧化碳将大幅度增
