There is increasing awareness of the role that greenhouse gas emissions play in global climate change. How do greenhouse gases affect our environment and how can worldwide greenhouse gas emissions be controlled?

Most people now agree that carbon dioxide, methane and other emissions contribute significantly to climate change. These ‘

greenhouse

’ gases prevent sunlight from escaping

Although

the American government has chosen not to support the Kyoto treaty, other countries are working together to reach targets set by the UN for the reduction of emissions and the stabilisation of world temperatures. Despite setbacks, there has been some success in

area, and provided America can be convinced of the reality of global warming,

hopefully they, too, will join in the struggle to control

emissions. Another solution might be the encouragement of investment in alternative energy sources. Wind

However

, especially now that the world seems to be exhausting its supply of these non-renewable sources of energy. In the wake of the Kyoto Agreement, many wise governments have begun to prioritise investment in these new industries. In conclusion, the
