全球气候变暖影响英文版

1．One 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 and 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 migrating 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 (big 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 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 Fahrenheit. 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 the 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 rise. Desertification will also be a problem for humans, food may become scarce.

3．One 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 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 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 fact that ecological crisis and violence are both linked.

4．Economic 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 millions 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$ billion 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.
