Introduction

Global warming What is Global Warming? The term Global Warming refers to the observation that the atmosphere near the Earth's surface is warming. This warming is one of many kinds of climate change that the Earth has gone through in the past and will continue to go through in the future. It is reasonable to expect that the Earth should warm as the amount of greenhouse gases in the atmosphere increases. It is known for certain that atmospheric concentrations of greenhouse gases are rising dramatically due to human activity. It is less well known exactly how the increases in these greenhouse gases factor in the observed changes of the Earth's climate and global temperatures. What causes these global warming effects? Global warming effects have and will always vary for natural reasons. However, human activities are increasing drastically the concentrations of some gases in the atmosphere, such as greenhouse gases (mainly CO2), which warm the earths surface Although more research is needed, understanding of global warming effects processes and computer models have improved. ...read more.

I believe volcanoes contribute to the greenhouse gases because they release enormous amounts of gases in a small period of time, animal waste, also adds to the greenhouse gases, the west German chemists suggest that the world's cattle emit into the atmosphere approaching 100 million tonnes of methane each year, enough to warm up the planet. As this graph suggests, the world is producing more methane than ever before, this rise could explain the rise in temperature over the last few years and negate belief that CO2 emissions is the main cause for global warming. This graph also backs up the point that Carbon dioxide Is one of the culprits for global warming, as you can see in the graph CO2 is closely linked within the temperature. And here is the Methane graph, this also shows that this is also a contribution towards global warming, as you may see within the graph. My opinion on the causes of global warming is that it is a natural cause Yes, climate fluctuation happens naturally but natural changes occur over thousands of years. ...read more.

Conclusion

Government Government regulation: Government can require desired behaviors (e.g., force auto companies to build more efficient cars). An advantage of regulation is that it specifies the desired outcomes and can force action. However, regulation can be inflexible and discourage innovation. Prices and markets: Higher prices for fossil fuels encourage people to save energy by promoting energy efficient devices and behavior (e.g., expensive gas prompts companies to make and people to buy more fuel efficient cars). Government subsidies and taxes can also influence behavior. An advantage of using prices is that they present a constant incentive to innovate. However, using prices can have undesirable side effects, such as imposing a relatively larger burden on the poor. Information and education: People often do not know how to improve efficiency or reduce emissions. Government can provide them with the information they need to make better choices. Research and development: Government and industry can support research to demonstrate and improve existing technology, and to develop new technologies that use less energy or emit no carbon dioxide (e.g., refrigerators that use less electricity, cheap practical solar water heaters, and inexpensive solar/hydrogen technology). ...read more.

  1. Is global warming human induced or is it a natural phenomenon?

    So the truth is, the temperature is rising naturally and it would have done so with or without human interference. The temperature increases, however, would have been at a lot slower rate, but because of human interference the rate of temperature increase is a lot higher.

  2. The Truth about Climate Change

    Here's what I got, top ten countries that emitted the most carbon dioxide in total, with the amount they emit in metric tones, and the CO2 it emitted compared to the total CO2 emitted in the whole world in %, and also how much CO2 on average each person in that country emitted.

Scientists generally believe that the combustion of fossil fuels and other human activities are the primary reason for the increased concentration of carbon dioxide.
