The principal greenhouse gases are carbon dioxide contributing the major share along with other trace gases as stated earlier. Plants are considered as the main source of consuming CO2 from atmosphere however deforestation by the human being for urbanization or other purposes is reducing the number of plants and increasing the concentration of CO2.
EPA uses national energy data, data on national agricultural activities, and other national statistics to provide a comprehensive accounting of total greenhouse gas emissions for all man-made sources in the United States. Thus major driving force of climate change of 21st century will be enhancement of GHGs.
The rise of CO2 level have immediate effect on the rise of global temperature. There are steps being taken at this moment to reduce the gases put into the air, but it still is not enough.
Carbon dioxide CO2 is a green house gas emitted by both natural and human activities. The increase in transportation is directly due to the growing population and the need for jobs and the growing congestion on our highways. If this is not met, force the business to pay a monetary fine.
The climate change hazards are given in Table Plant a tree, or take a bus or carpool to work instead of driving your own car. More people will likely be affected on the globe by tropical diseases, in coming decades as globe will become warmer in future.
This is often called carbon trading. There is also a prediction of regional climate changes along the ecosystem. More efficient use of fuels conserves the shrinking supplies of energy resources.
The world community should strive to achieve a low energy future of the kind spelt out by the end-use global energy project, with a world energy conservation of not much more than around 12 terawatts TW bybut spread through the world more equitably than the 10 TW consumed today, so the developing countries can enjoy standards of living akin to those enjoyed in the industrialised countries.
Another approach to the problem is to increase the amount of CO2 removed from the atmosphere. Global Warming and Greenhouse Gas Emissions Essay 5 words Green house gases are the gases in the atmosphere trapping heat from various sources which ultimately causes greenhouse effect.
The greenhouse effect is one of the most important factors and is one which humankind has the capacity to change. If enough biomes is present the excess CO2 can be used by vegetation during photosynthesis, thereby reducing the impact of CO2 released by fossil fuel burning.
Although changes in sea-level have received much publicity, problems of water availability are likely to be more serious and perhaps more expensive to solve. The United States government should also make public transportation more appealing and efficient.
They have ability to absorb heat from atmosphere and emit radiations within the thermal infrared range to the atmosphere causing more heated earth surface. The glass lets the sunlight in to make heat, but when the heat tries to get out the gases absorb the heat.
Some of the natural processes maintain the balance of green house gases on the earth however variety of human activities have already disturbed this balance in the atmosphere which has created global warming.
Emissions of carbon dioxide, which account for about three-fourths of total emissions, increased by 42 percent over this period.
The Cretaceous period occurred over a hundred million years ago. The earth is naturally heated by the greenhouse effect. The main routes to surviving the greenhouse threat are energy efficiency, renewable forms of energy production of all CFCs and related gases, less greenhouse gas-intensive agriculture, stopping deforestation and reforestation.
Seasons become more extreme when the opposite happens. This pattern of consumption should be achieved by massive investment in energy efficiency in the industrialised countries and large-scale transfer or up to date energy efficiency and non-CFC dependent technologies from the industrialised countries to the developing countries, to enable them to leap-frog the kind of energy-intensive, polluting routes which the developed countries took during industrialisation.
There is a natural carbon cycle in the atmosphere managing CO2 level however various human activities are altering this by adding more CO2 gas to the atmosphere by reducing natural sinks like forests. The details of EL Nino climate events are given in box Thermal expansion, mountain glacier melting, Greenland ice sheet melting and Antarctic ice sheet melting.
Though the GHGs effect on climate is slow and imperceptible immediately but its impact on climate change in the long run become alarming and irreversible.
The emission of CO2 and other green house gases have been increased in the atmosphere since the industrial revolution. The details of warming potential are: Thus approaches to dealing with climate change involve technological change coupled with political will and economic realities.Essay on Climate Change.
Climate Change Two of the main human causes of climate change are greenhouse gases and land use changes. Greenhouse gases trap heat in our atmosphere and can remain there for thousands of years. Certain of these gases will block heat from leaving the atmosphere.
Warming and Greenhouse Gases The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide.
- Global Warming and Greenhouse Gases The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily.
Greenhouse gases from human activities are the most significant driver of observed climate change since the mid th century. 1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere.
The Simple Global Climate Change Essay Formula. An essay on climate change is not overly difficult to write, as long as you enjoy the topic. There are many climate change essay topics you can choose from, so make sure you pick an interesting topic that fits in your area of expertise.
carbon dioxide is a greenhouse gas – it absorbs. The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car.
The glass lets the sunlight in to make heat, but when .Download
