1、1One of the effects of global warming is the destruction of many important ecosystems.Changing 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 a
2、nd biological systems. 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 migr
3、ating to better suited geographical 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 (b
4、ig floods), drought, wildfires, ocean 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
5、planet. 2 Another important effect that global 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 11.5 degrees Fa
6、hrenheit. These mass extinctions will be due to 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 th
7、e world where they can survive. A good example of that 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 ri
8、se. Desertification will also be a problem for humans, food 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
9、 for example, in that region global warming has played an important 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
10、 started during a time of intense drought. Scientists and military analysts 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 fac
11、t that ecological crisis and violence are both linked. 4Economic calamities are 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 mil
12、lions of dollars in damage. When severe storms and floods occur, crops, homes, businesses, 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$ billi
13、on in property damage. That really hurt the economy that year. When severe weather does damage 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
14、 economy can be disastrous. 5 Drought is an effect of global warming that we are already seeing 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 Sci
15、entific American predict that drought conditions could increase by as much as 66 percent. Drought will 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
16、 famine on their hands. Currently, India, Pakistan, and some parts of Africa are already experiencing droughts. 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
17、. When you look at the scientific data concerning storms and floods in the last 30 years, you will see that category 4 and 5 hurricanes have nearly doubled in occurence. What many people don't know or realize is that warm waters give hurricanes their strenght and power. Many scientists today are
18、 associating the increase in ocean and atmospheric temperatures to the rate of violent storms. Between the years 1905 and 2005 the frequency of hurricanes has been on the rise. From 1905 to 1930 there were an average of 3.5 hurricanes per year, 5.1 between 1931 and 1994, and 8.4 between 1995 and 200
19、5. 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 recently, Australia has seen the worst flooding they have had in a long time. 6Heat waves are also an effect of global warming. It is no secret that temperatures are
20、breaking records in the US and Canada and abroad. More extremely hot summer days are in store for North America and elsewhere if global warming 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
21、people having heart attacts, strokes, and asthma attacks. Children, the elderly, poor, and people of color are more vulnerable to the effects of a heat 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
22、 effect of global warming is the shrinking of glaciers, this is happening wherever there are glaciers worldwide. Mountain glaciers have been in retreat for a long time now as global warming continues to effect us. What many people don't realize though is that it is happening more rapidly now the
23、n previously believed. Glaciers don't only recede they also shrink vertically. The lakes this melting produces can also lead to more melting. These lakes are like a cancer that is consuming our world's glaciers. Here is a fact that may surprise you: Even if all the world's mountain glaci
24、ers 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. 8Global warming will also bring a rising of sea levels around the world. As glaciers and polar ice sheets melt, the sea levels
25、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,our world is becoming hotter and hotter.And we called it“Global Warming”which is to describe the rise of temperature
26、.The Global Warming has two sides of effect to the worlds creature.First,the Global Warming means there is more carbon dioxide in our atmosphere.So some plants can grow faster and stronger than before.This is its good effect.But on the other hand,the Global Warming will bring us more disasters than
27、fortune.Because of the more and more carbon dioxide in the atmosphere,the earths temperature is rising day by day.The high temperature will cause many serious problems.Like the ice of Antarctica and Arctic Ocean begin to melting.After that happen, the height of sea level will lift.Then some terrible
28、 disasters will coming,like tsunami and so on.Maybe 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 atmosphere.Especially methane and
29、carbon dioxide.These gases make the temperature rise day afteer day.And that will cause many natural disasters.Like tsunami,flood, drought and so on. Finally ,if we dont stop, the world will become a death world without lives.Our fate will like the dinosaurs.Another main reason of Global Warming is
30、the fast growing of the worlds population.So if we dont control the speed of growing population,the situation will be worse. So is it already too late to prevent the Global Warming?I think it is still not too late.If we plant more trees,produce less greenhouse gases like methane and carbon dioxide,a
31、nd to control the growing of population.The situation of Global Warming will be better.And we must to do it first in our daily lives.Go to work by bus or on foot I think,is the best way to prevent the worse situation of Global Warming.全球氣溫變暖的主要原因: 人類活動(dòng)對(duì)氣候變化肯定是有變化和影響的。人類燃燒煤、油、天然氣和樹木,產(chǎn)生大量二氧化碳和甲烷進(jìn)
