The Global Climate Change Debate Essay examples
Climate is defined by the Oxford Dictionary (University, 2015) as the average weather conditions prevailing in an area in general or over a long period. It includes patterns of temperature, precipitation (rain or snow), humidity, wind and seasons (Adelsman, 2012). When there are changes in long-term averages of daily weather this is called climate change. Scientists believe that climate change is linked to the increasing concentrations of carbon dioxide (CO2) along with other gases in our atmosphere. The consequences of climate change include rising sea levels, extreme weather, melting ice, and impacts on animal and plant life. There are also people who are sceptical about global warming, the causes and effects.
Shorter term changes are referred to as climate variation; this includes events such as the Mini Ice Age and Medieval Warm Period (Dunbar, 2014).
When explosive volcanic eruptions occur, they force dust and gases such as carbon dioxide sulphur dioxide into the atmosphere. We would expect that the increased amount of carbon dioxide in the atmosphere to cause warming (the greenhouse effect) however this is usually not the case. This is because the sulphur dioxide rapidly turns converts to highly reflective sulphuric acid aerosols (minute particles suspended in the atmosphere) which scatters sunlight causing a “reduction in the solar beam” therefore having a cooling effect on the Earth.
