Global Warming is the increase of temperature on Earth which is caused by human activities and will have very serious consequences for life on Earth if humans don't start to do something about it now. Global Warming is caused when the Greenhouse Gases combines with the atmosphere and traps heat. It is strongly related to pre-human and pre- industrial global warming, it is also weakly related to depletion of ozone layer, which was caused by the CFC (Chlorofluorocarbons) gas. The effects of global warming on the environment are dangerous, such as: rising of sea level because polar caps melt, changes in the pattern of precipitation, floods, droughts, heat waves, hurricanes and tornadoes. These effects would take away life and destroy houses or anything else human made.
The Problem of Global Warming "The climate of the Earth is changing" (Melillo 1999:183). These words sum up exactly what is happening to the environment today; it is changing. Yet, what has brought on this change? There are many factors that contribute to climate change, however, the most important one that has become a very relevant issue to humans today is global warming. Global warming is the increase in the Earth's average surface temperature from an increase of greenhouse gases (primarily Carbon Dioxide) in the atmosphere.
Also, ocean acidification is also affected by global warming. Carbon dioxide is one of the greenhouse gases that cause global warming. So due to the rise in sea levels and precipitation, the carbon dioxide is mixed more with sea water, and this is a major concern for our aquatic life, especially for our corals. Most importantly, global warming affects the weather. Global warming affects the weather by making the climate hot or cold, or switching it back and forth (National Geographic).
With the rising temperatures the stretch of the deserts would increase. Carbon dioxide increases the evaporation of water into the atmosphere. Since water vapour itself is a greenhouse gas, this causes still more warming. The warming causes more water vapour to be evaporated. The C02 level is expected to rise in future due to ongoing burning of fossil fuels and land use change.
It is very difficult to reverse this process once it is started. If we want to live like we are now and have been we have to stop this process. Emissions of fossil fuels by humans is a big factor of global warming. The reason being is because of the amount of carbon dioxide released from the fossil fuels. Controlling these emissions is one huge step of many steps required to slow down and stop global warming.
Scientists blame the greenhouse gas effect in combination with societies greenhouse gas emissions for the rising temperature. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is emitted back towards the earth’s surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases (Intergovernmental Panel on Climate Change).

Because these things will affect society, there are important decisions that have to be made in the present as well as in the future to secure people’s lives and lifestyles.
Jose Gaxiola Edson Ferreyra April 24, 2014 Period. 5 Economics Global Climate Change Global climate change has been a very controversial topic due to the effects it has caused in the world. Scientists believe that if global climate change is not controlled, it will have a greater impact on the world and its people. Global warming is the rise in temperature around the world’s atmosphere caused by greenhouse gases and the excessive amounts of carbon dioxide. Many of earth’s features have been affected and rearranged due to higher temperatures in climate change.
There are people in the world that believe that there is another reason why this is happening; earth is experiencing a natural cycle of evolution. Global warming is a very serious part of the world and a solution needs to be found immediately. The greenhouse effect is the cause of global warming in the world. The greenhouse effect is a topic of discussion throughout the world; it needs to be contained immediately. “Our effect on the environment, and in particular on climate change, is large and growing” (Tony Blair) The greenhouse effect is when sunlight and solar radiation enters the atmosphere and hits the earth and bounces back, but with the greenhouse effect it then goes back up into the atmosphere and is deflected back down and trapped in the atmosphere (Energy and the Environment).
Some of these threats include the altering of crop seasons and even effect the way organisms survive on the planet. The first thing I think I should discuss when talking about global warming is what causes it to occur. Gases such as carbon dioxide, methane and nitrous oxide, which are known as greenhouse gases, all build up in the atmosphere of the earth. All these gases make it so that it becomes harder for the radiation that the sun shines into the atmosphere to escape. The heat continues to build up and this is what causes the temperatures to increase.
Global warming is the gradual rise of the earth’s surface temperature, caused by the release of greenhouse gases that become trapped in the earth’s atmosphere. These trapped gases are responsible for the changes in the global climate patterns. Greenhouse gases are considered any gas that is absorbed into the atmosphere such as carbon dioxide, methane, and water vapor while preventing the sun’s solar rays from escaping back out into space. There is a natural process called the greenhouse effect that is required to keep our planet sustainable, without this process Earth would be uni... ... middle of paper ... ...eel the calamity in the coming years. Rising temperatures will drastically change our climates and ecosystems into something far removed from the natural we have seen over centuries before us.
