Discussion 9For sometime now, human impact on environmental change has become the focus for scientists and environmental conservatives. The risks resulting from climatic change have attracted mixed reactions. Accordingly, some of the firms argue that their revenues will be seriously affected by the carbon dioxide emissions’ controls and therefore, has poured cold water on the global warming findings. According to the Intergovernmental Panel on Climate Change (IPCC) scientific consensus has been arrived at concerning the present global warming trend. This is due to increased greenhouse gas emissions, which have anthropogenic climate changing effect. The United Nations Development Programme (UNDP) in a report, the human development report 2007/2008 indicates that human development challenges of this century are partly due to anthropogenic change.
The assertion here is that the inability to reduce the global warming impact will result in increased poverty among the poorest countries that ironically are the least contributors to the problem. Human beings are involved in climate change processes. Their activities, which include burning, coal, gas, oil, and deforestation is the main reason for temperature changes. Accordingly, heat-trapping emissions also known as greenhouse gases have increased steadily over the years with CO2 gas as the biggest driver in this change.
Statistics indicate that CO2 is the leading contributor in surface warming influence from as far back as the year 1750 followed by methane and halocarbons. Apparently, more CO2 emission remains in the air today unlike it was fifty years ago. The issue of anthropogenic change remains emotive. Some companies such as Exxon Mobil have gone to lengths to try to confuse the public concerning this issue. The Union of Concerned Scientists (UCS) in the US reported that Exxon Mobil had spent $16 million to accomplish skeptical campaign on the global warming issue.
Concerns about anthropogenic change have led to a number of campaigns by both activists and conservatives. One such campaign utilizes the ecological footprint, which is a measure of how much demand on the earth’s ecosystem is being exerted by human beings. The footprint calculator derives measurements for nations and activities. The former measures the global hectares required by a definite population regardless of their location. This differs between countries. The other measure covers the types of products or service provided by a global hectare.
This measure covers areas of greatest strain on the earth’s ecosystem. The footprint calculator as a method calculates the climate change impact for an individual. Hypothetically, if: I live in the United Kingdom traveling mostly by car. Holiday close to home and have a medium sized house. Stay with three other people and buy electricity from non-renewable resources. Am a regular meat eater as well as fresh convenience food and produce an average amount of domestic wasteMy footprint according to the calculator is 11.2 tons CO2 with a footprint of 5.7 hectares.
If everyone would be living like me, it would require four planets to support global consumption. Ascribing to the global citizenship concept is increasingly becoming important for all those who are environmentally conscious. The forum is keen on addressing inequalities and actions that compromise others’ well being. Environmental degradation is one such consideration. Cutting down on coal, oil, and gas energy sources help to reduce CO2 emissions. The dependence on cleaner energy sources such as nuclear compared to hydro or coal will ensure considerable reductions with a 3.10g/kWh, 10g/kWh for nuclear compared to 11g/kWh for hydro.
