MAIN BODY
A. What is the climate change and cause
1.Definition
The term ‘Climate Change’ commonly refers to influence s on climate resulting from human practices. Increases in the concentration of so-called greenhouse gases in the atmosphere resulting largely from burning of fossil fuels and deforestation, have led to an observed and projected warming of the earth, known as the enhanced greenhouse effect. It is not easy to distinguish this anthropogenic climate change from the natural variations in the drivers described above.
The Intergovernmental Panel on Climate Change (IPCC) says many parts of the planet will be warmer. Droughts, floods and other forms
of extreme weather will become more frequent, threatening food supplies. Plants and animals which cannot adjust will die out. Sea levels are rising and will continue to do so, forcing hundreds of thousands of people in coastal zones to migrate

1.Summary : Expert’s view
The current scientific consensus is that the build-up of greenhouse gases such as carbon dioxide will lead to a significant warming of the Earth over the next 100 years.
The economic effects of global warming could be very significant, especially for the agricultural sector of the economy.
The potential solution to global climate change falls into two categories: adaptation and mitigation.
•Adaptation is the alteration of consumer and business behavior to reduce the damage from global climate change.
–This approach uses price increases and the resulting incentives to minimize the harm from global warming.
–The impact on some groups in the society could be high.
•Mitigation includes policies to significantly reduce emissions of greenhouse gases.
–This approach also prefers to use price signals to slow down the emission of greenhouse gases.
–One proposed means for reducing the incentive to burn fossil fuels is a carbon tax.
–The tax rate would vary for different fuels according to their carbon content.
The other proposed alternative is to use the cap-and-trade system
