yes the factories and stuff like that are making the air horrible
A:Global warming is a very big issue in the world today. Global warming is when the earth's temperature rises. The cause of global warming is when greenhouse gases trap heat and light from the sun [in the atmosphere of the earth] causing the earth to heat up. Global warming affects animals and our environment, such as rise in sea levels which will cause extinction for more than a thousand species.
Increasing levels of carbon dioxide and other greenhouse gases
Increasing levels of carbon dioxide and other greenhouse gases
Global warming has already started. If we stopped carbon dioxide emissions today, there is still enough additional greenhouse gases in the atmosphere to continue warming for some years. We can prevent the worst case of global warming, but governments have to take serious action first to reduce, and then to ban carbon emissions altogether.
Climate scientists have studied the effects the enhanced (or accelerated) greenhouse effect which is causing global warming and they are worried. They are worried because they have spread the message to the world but very few governments are prepared to take serious steps to combat the problem.
While we do not fully understand the mechanisms that have caused the years of warming, we do believe that man has contributed to the situation. We should try to find legitimate ways to reduce our use and dependance on fossil fuels.
We are adding more and more carbon dioxide to the atmosphere. This is causing global warming and climate change.
well it want has bad as it was today because of us how we are using alot of heat we are causing the temperature to rise
The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
The greenhouse effect is the way the greenhouse gases (water vapour, carbon dioxide, methane etc) in the atmosphere trap the sun's heat to keep the planet warm. This effect is supported by the water and carbon cycles of the earth, and has been going on since life began.Global Warming is the warming of the earth during the past 200 years but especially since about 1970. Man discovered and started burning fossil fuels (coal, oil and natural gas) which releases carbon dioxide into the atmosphere that had been hidden away for millions of years. This extra CO2 is disrupting the natural greenhouse effect and is causing the enhanced greenhouse effect.It is this enhanced, or accelerated, greenhouse effect that is responsible for global warming.A:Global warming, as the word has been used in recent years, is an increase in average temperature of the earth due to an increase of greenhouse gases. Greenhouse gasses are gases that trap a great deal of heat. These include CO2 and Methane. Anthropogenic global warming is a certain type of global warming caused by human production of greenhouse gases through the burning of fossil fuels and by deforestation.The Greenhouse effect is the phenomenon of heat from the sun being trapped by greenhouse gases in Earth's atmosphere.
Man, unfortunately, causes most of the present global warming, because for the last 200 years we have been burning fossil fuels (coal, oil and natural gas) which release extracarbon dioxide into the greenhouse gases in the atmosphere. We have also been seriously cutting down the great forests of the world, which used to be able to absorb enough carbon dioxide from the atmosphere to keep the temperature comfortably steady.
The earth is surrounded by an atmosphere of air, made up of a number of gases. These greenhouse gases prevent some of the sun's heat (infrared radiation) from reflecting back into space. If this greenhouse blanket was not there the surface of the earth would be about minus 18 degrees C (0ºF), instead of its present average temperature of 15 degrees C (59ºF). So this natural greenhouse effect is very useful. One of these greenhouse gases is carbon dioxide (CO2). About 200 years ago humans started pumping extra carbon dioxide into the atmosphere, when the first factories began. Today the concentration of carbon dioxide is 35 per cent greater that it was in the 18th century. We have increased other greenhouse gases too, like methane, nitrous oxide and ozone. These increased amounts of greenhouse gases trap more infrared radiation and the earth's lower atmosphere is warming up. This is known as the enhanced greenhouse effect and is causing global warming, which, in turn, is causing climate change. This is made worse by deforestation because plants take in CO2 and without them, less carbon dioxide is taken in, which in turn traps more heat.
