CLIMATE CHANGE Let’s first begin with “what is climate change?” – it is a significant and lasting change in the statistical distribution of weather patterns over periods of decades to millions of years [1]. Climate change is caused by several factors [2]: * Internal forcing mechanism (Natural processes of the climate system itself) * Ocean variability * External forcing mechanism (A process that alters the balance of the climate system [3]) * Orbital variation * Solar variation

ahead 20 to 50 years‚ which are the societies likely to be most hit by climate change‚ and which the least? What are the most important impacts likely to be? The evolving global problem of climate change looms large with inevitable social‚ economic and ecological challenges for the world. The process of global warming and its consequences vary from region to region‚ but the nature of these variations is uncertain. The changes will not occur in a fast way‚ nor will they only exert a negative effect:

Climate Change in Victoria What is Climate Change? The Earth’s climate has changed over the last century. Increases in average temperatures have been seen around the globe and there is new and stronger evidence that most of the warming observed of the last 50 years is due to human activities. While climate change is a global issue‚ it will affect us all. Climate change has the potential to adversely affect our environment‚ our communities and our economy unless we take action now to reduce our

in the world today‚ its break off from the ancient supercontinent Gondwanaland 30 million years ago‚ played a crucial role in stabilizing the climate for human life. In particularly‚ Its separation from South America created water gaps which allowed winds to sweep around the world.In addition‚ the separation created a cooler climate more stabilized for human life (Linden‚ 35). It was not until 5‚000 years ago when urban societies developed laying the foundations for civilizations. A civilization

Greenhouse gases are the cause of global climate change. The main greenhouse gasses are water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and chlorofluorocarbons. Although most of these gases are natural‚ they are all being put into the air at a much more dangerous rate than normal. Water vapor‚ the greatest natural contributor to global warming‚ and lasts about nine days in the atmosphere. Water vapor is in the atmosphere more recently‚ because there has been more water that has evaporated because

The average temperature of the earth’s surface is rising. According to the Natural Resources Canada: Overview of Climate Change in Canada‚ “the influence of anthropogenic climate change on Canada is evident in observed trends and temperatures simulated by global climate models” (Government of Canada)‚ which can have devastated impacts on humans (e.g. humans can die of heat stroke). The summer issue of Statistics Canada’s EnviroStats (2011) has a nation-wide survey on air conditioning. Surveys demonstrate

of Climate Change Relating To Polar Ice Climate changes occur naturally over long periods of time on Earth‚ and it has been this way throughout Earth’s history. Currently‚ anthropological influences on earth have triggered a quickening rise in global temperatures and this in turn is causing a rapid change in earth’s climate. One of the major changes currently happening on earth is the melting of the polar ice caps. Major impacts relating to the melting of the polar ice caps include changes in ocean
