The Effects of Global Warming
The facts
Together we can save the planet.
We Have the Power to Impact Our Future, and We’re Doing Something About It
They have planted crops according to seasonal rainfall and frost and colonized islands, thinking them pristine and safe from outside interference. In the 20th century, however, these certainties have been called into question. The effects of global warming will likely cost human society dearly.
Over the last 10,000 years, temperatures have remained remarkably stable across the globe-changing by little more than 2F (1 ‘F equals approximately 1.8C) on average. Even during the Little Ice Age, which lasted from the 14th to the 19th century and left a legacy of advancing glaciers, stunted crops, and death from exposure in Europe, mean temperatures were little more than 2F ( older than (hey are today. The effects of global warming could change average temperatures five times as much as the Little Ice Age did-though in the opposite direction.
Over the next century, the rate of The effects of global warming should follow a steep upward curve-heating up just a bit in the 1990s and progressively more each decade thereafter-until the earth’s temperature rises to the sweltering levels that occurred hundreds of thousands of years ago. Such catastrophic temperature changes do occur every 80,000 or 90,000 years, when the earth’s orbit swings it far enough away from the sun to create an ice age, but the biosphere has thousands of years to prepare for it.
Although most scientists agree that the globe will heat up between 2f and 9F by the year 2050, the computer climate models that generate these warming predictions are still too clumsy and simplistic to predict regional climates. A typical model can predict climate change across an area of hundreds of thousands of square miles. All the countries of central Europe might be subject to the same climate prediction even though each country’s seasonal temperature, rainfall, and snowfall patterns are unique. Using even the best climate model to make such specific forecasts is a hopeless task at present.
Computer climate models can, however, predict climate trends across the globe under higher temperatures.
They can determine that The effects of global warming will make summers drier in mid-latitude areas across the planet-even though they might not be able to foretell the average summer rainfall in California in the year 2050. These predictions sketch a general picture of how The effects of global warming will affect climates across the face of the globe and how such changes might disrupt civilization and the biosphere.
The earth’s northern latitudes should feel the most dramatic effects of The effects of global warming. As the Arctic and Antarctic ice packs shrink and the exposed tundra and seas absorb heat that was once reflected back into space, the poles will probably heat up at an accelerated rate. Climate models predict that if The effects of global warming raises temperatures by 3.5�F on average, then temperatures in the Arctic could warm up by as much as 7�F. (Where as Arctic winters will be especially warm, Arctic summers will grow only slightly warmer.) The equatorial regions, on the other hand, will be less subject to The effects of global warming, perhaps heating up a degree less than the global average. As the world’s oceans are fed by melting glaciers and ice caps, sea levels will rise by as much as 3 feet (1 meter) within the next 100 years.
As temperatures rise, the oceans will evaporate more quickly, creating more clouds and more rainfall. According to Jonathan Wiener, author of The Next One Hundred Years, 500,000 cubic kilometers of water rise and fall between the oceans and sky every year-an amount that could increase by 25,000 cubic kilometers under The effects of global warming. (One cubic kilometer is equal to a volume of space about 12 city blocks long, 12 blocks wide, and 12 blocks high.) However, this extra rain may fall when and where people least need it. Subtropical areas, such as India, may be hit with heavy floods and monsoons, and vulnerable farmlands in temperate climates will experience droughts.
At high latitudes, in areas such as Canada, warmer temperatures will mean longer growing seasons and more rainfall. Soviet climatologist Mikhail Budyko, one of the earliest investigators of The effects of global warming, believes that this process will bring food and prosperity to vast areas of the globe that have been desolate for thousands of years. Central Asia, he predicts, will receive 50% more rain, and the Sahara may receive 12 inches (30 centimeters) more rain every year by the late 1990s. Altogether, he believes that increased rainfall and agricultural productivity (rising CO2 levels will also increase the rate of photosynthesis) should raise world food production by 50% in the year 2050. Such optimism is rare among scientists studying The effects of global warming.
Whereas mountain snow packs in latitude areas such as California and Colorado should melt earlier-meaning more rainfall and river water in the spring-midsummer, when crops need the water most, will be drier. Together with the increased probability of heat waves, these conditions could lead to frequent droughts and spreading deserts in areas such as the Great Plains and Western Europe.
Given these general outlines, it is possible to imagine endless environmental disasters caused by The effects of global warming. Will Antarctica’s western ice shelf drop into the ocean? Will California become a true desert? The initial effects of The effects of global warming need to be looked at in more detail.
Opposing Viewpoints global warming is a threat?
Some scientists believe that global warming is not a threat and the world is essentially cooling. They argue that the factors causing the problem and the measures are not fully understood, and it is impossible to draw conclusions if global warming is a purely natural event. These people believe that the trend is a hoax and that is not a sign of a global disaster ahead. In addition, the strengths of the industry assert that human beings can adapt to the changes caused by global warming, but they refuse to talk about something about the environmental impact of climate change.
Other opponents of the global warming theory believes that most of the changes are due to the sun’s energy is fluctuating. Large sunspot activity is held partly responsible for the \ “Little Ice Age \” from 1450 to 1850. This climate change is well documented in history, with many effects on civilization in Europe, including famines. Fluctuations in temperature was only 2 degrees Fahrenheit. Also, some researchers believe that the smoke from the burning of tropical forests and meadows leads to a cooling of the strong force on the climate. The cooling effect could almost as much as your brain power built by greenhouse gases created by the fires.
Furthermore, as regards the question sea level rise, it is important to realize that increases in various coastal areas are rising and sinking due to geological factors. Thus, the oceans can not increase as much as we think, as a continent may be sinking.
In addition, some researchers believe that global warming is foreshadowing a future ice age. The last glaciation occurred when the Earth \ ‘is global warming. In the Arctic regions, larger quantities of water evaporate in the summer and fall to the ground as snow in winter. Winters would not be as warm as to melt all this snow, which would increase the glaciers. In addition, some compounds of carbon dioxide are released into the atmosphere can help prevent global warming. These particles reflect sunlight, which is redirected into space.
Effect of Global Warming – The way to reduce global warming.
There are several things you can do directly after reading this document. However, some of the actions that we must all take a slight decrease in your current standard of living.
First, since most of the electricity in the United States is produced by burning coal, we should try to cut down on our electricity demand. (See chart No. 4) coal creates the largest quantity of CO2 per unit of energy of a fossil fuel. Coal and oil together represent 80% of the U.S. supply of fuel used to generate electricity. When we reduce the use of electricity, we save money, breathe cleaner air, and to help reduce the problem of global warming. Every kilowatt-hour of electricity saved retains 1.5 to 2 kilograms of CO2 from the atmosphere. Americans waste more energy than any other country. I think it is time to take our lives, factories, houses and more efficient. Look around at home and in your workplace, and there are many ways in which you can reduce the use of electricity. For example, planting trees on the south side of your home where they can provide shade during the hot summer months. Also, installing a thermostat for energy efficiency, with a timer day and night.
ECONOMIC ASPECTS:
Global warming is big business. Some economists argue that global warming could benefit from some crops and farming communities. However, although insurers are worsening forecasting storms caused by global warming could eventually the insurance industry into bankruptcy. Insurance companies are now trying to form strategic alliances, and to pool resources that could bring serious economic losses from climate change.
In addition, the cost worldwide to implement a plan to reduce the production of CO2 and other gases that contribute to global warming would cost approximately 3 percent of the world \ ‘total GDP . However, there is a dispute whether the industrialized world should be responsible for the major economic contribution to clean this planet. It is important to realize that many less industrialized countries can not afford measures to avoid an increase in CO2 emissions, and the fact that they have no incentive to reduce carbon emissions causing \ “Greenhouse \”. Many less industrialized countries argue that the developed world has been authorized to use nature in the creation of well-being, and that it is morally right now for them to do the same. I believe that the funds provided under the former Cold War must be used for the Global Ecology.
Second, reduce the use of your car. If you can \ ‘t afford to buy a new car fuel-efficient in the coming years, consider selling or junking your gas demanding and buying a smaller car, effectively used car. In addition to saving money on gas, oil, tires, parts and repairs, you can help reduce greenhouse gases. In addition, regardless of the vehicle type, remember to function effectively, try to carpool to work or ride the bus, keep your car tuned up, walk or ride your bike for short distances, and the park on foot are not using \ “Cross” services.
Thirdly, try to follow the aftermath of the environmental policy of \ “Reduce Reuse …. ….. Recycle. \ “Reuse of all is the easiest and the best way to recycle. Save containers, bags, anything you can use in the future. Also, the use of toilet and cloth napkins instead of paper, and the use of rechargeable batteries instead of disposable ones.
In addition, you can reduce the need to recycle paper down on junk mail lists. Why trees should be destroyed for messages that you do not even want to receive? In addition, always remember that recycling is only effective when you purchase products made from recycled materials. Otherwise, what’s the point of recycling?
Also, remember that every time you make a purchase, you either strengthen poor product, or you encourage a good thing. I think people should try to buy quality products that can be used for a long time, buy products with minimal packaging and not buy disposable products. We certainly have to make up our minds that our success as an individual must not be based on the quantity of our consumption, or the quality of our natural environment.
I think it is time to revisit our moral values. To examine our attitudes with regard to our natural world. Each of us must ask the question: What makes us really happy? What makes us feel safe? It is very questionable if the money and other items make us happier, it is even possible that we tend to be less satisfied with our life \ ‘s where we have a lot of money and other maintenance . Our research has increasingly materialistic consumption caused us to forget that we are living human beings? We must realize that we have much more in common with plants, animals, air and water that we have with the mechanical, chemical and electronic world, we have created around us.
