The earth 's climate is generally defined as the average weather over a long period of time. A place or region 's climate is determined by both natural and anthropogenic (human-made) factors. As the rapid increase of population of the world the energy requirements of people are also increasing gradually. In the most part of the earth naturally and sometimes people burnt fossil fuels such as (coal, oil, green houses gasses) to meet their energy needs which release carbon dioxide, nitrous oxide, water vapours and methane which helps in change of climate of earth. What causes climate change? Our weather is always changing and now scientists are discovering that our climate does not stay the same either. Climate, the average weather over…show more content…
Since the industrial revolution, human activity has increased the amount of greenhouse gases in the atmosphere (shown in the graph to the right). The increased amount of gases which absorb heat, has directly lead to more heat being retained in the atmosphere and thus an increase in global average surface temperatures. This change in temperature is known as global warming. The increase in temperature is also leading to other effects on the climate system. Together these affects are known as anthropogenic (human caused) climate change. There are there important factors that change the climate. The main greenhouse gases include: • Water vapour. The most abundant greenhouse gas (GHG) • Carbon dioxide (CO2). Is actually only a small part of the atmosphere • Methane. The second most important GHG, is produced both naturally and through human activities • Nitrous oxide. A very powerful greenhouse gas which is heavily produced in the agriculture sector, specifically in the production and use of organic fertilizers. • Chlorofluorocarbons (CFCs). These man-made compounds were produced for industrial use, mainly in refrigerants and air conditioners. They are now regulated under the Montreal Protocol due to their adverse affect on the Ozone Layer. Water Vapour The water vapours (H2O) is the one of most important greenhouse gas. We understand it when we get a fall evening or spiring evening and the sky is clear, the heat will escape and the temperature gets low
