This information can be used to explain why there is not much being done in an effort to conserve the environment for the purpose of the future generations. The patterns on climate change that have been observed and documented indicate that this is a process that began a long time ago (Adler, Matthew. 2001, p.23). Precisely, it is not something that the present generation can be blamed of starting. However, the present generation is doing more harm to the environment which makes it inexcusable as far as environmental degradation is concerned. Since the industrial revolution, the atmosphere has been altered adversely, an action that has brought about climate change. The carbon dioxide concentration has increased by more than 30% since 1750 (Alley, Richard, 2000, p.13). This makes the present concentration to be the highest in 420000years. The main contributant of carbon IV oxide is the burning of fossil fuels which constitutes a 75% portion. The other reason as to why carbon IV oxide concentration in the atmosphere has risen so considerably over the years is the change in the way land was used where deforestation is the major culprit. Methane is another gas whose concentration has contributed to climate change. Reports place the figures at around 150% rise in the atmospheric methane gas which can also be attributed to the use of fossil fuels, agriculture, cattle, and landfills. Methane is more potent in bringing about global warming as compared to carbon IV oxide. However, the average concentration of carbon IV oxide in the atmosphere is in addition to its ability to stay in the atmosphere longer than methane. .
The computer simulations that are employed to predict the future climate places the figures at a very alarming position. Considering that aspects such as population, technology, and economic positions of the world are bound to change, the results would be expected to depict a much warmer and worse future climate.
