There is a lot of debate centered on the challenges brought by global warming and the effects that would result in further increase in global temperatures. Various scientists have given out varied explanations on the major causes of climate and global warming in the world today. Rosalind Peterson claims that human activities are not to blame for global warming and climate change because they are as a result of natural processes that take place on the earth however; global warming and climate change are man-made.
According to Peterson, who is the President of California and well known as the initiator of agriculture defense alliance, climate change and global warming are issues that results from the natural processes due to the natural causes. Here, he strongly opposes the idea that no human activity is responsible for the formation of climate change and global warming on the earth. In his arguments, Peterson asserts that human activities are not totally to blame for any climatic change in the environment today. He argues that the public should be educated so that they do not let the programs of climate change affect their activities. Supporting to his ideas, he explains that the temperature changes that are being experienced presently are not new as they have been seen in the past according to research conducted by NASA.
Peterson puts more emphasis on the fact that human activity should not be blamed for the many problems that the world is facing as a result of global warming. In fact, he claims that there is a lot of misleading scientific research data from various highly reputed scientists and organizations indicating that they are man-made. For instance, he points out that World Metrological Organization (WMO) and the Intergovernmental Panel on Climate Change (IPCC) are wrong in their conclusions that global warming and climate change result from human. This is because various other activities for example when the sun gets brighter it warms the planet, eruption of volcanoes also contribute to this fact. Furthermore, the author dismisses the organizations’ views with a lot of support from the current temperature statistics. However, the facts about the increase in the amount of carbon dioxide are a clear indication that it causes global warming.
Besides, he points out that this is strengthened by the statement that “emerging evidence pointing directly to other natural phenomena”. Here, he argues the rising amount of greenhouse gas emissions, particularly carbon dioxide, is not responsible for intensity of global warming on earth today. He further says that current statistics, according to NASA, ascertain that only 0.025-0.037% of gas emissions can be pointed to be the cause of global warming and climate change. With these results, Peterson puts forward his view that climate change is not greatly attributed to man’s activities though some of these activities contribute. In addition, a great increase in global warming happened a hundred years ago before man started his activities.
Peterson also opposes other scientists’ claims that carbon dioxide is a major contributor to global warming because the gas is known to have a very small concentration in the atmosphere at only 0.04%. He puts more emphasis on the fact that global warming sources are natural, he indicates that solar changes, including both magnetic fields effects and irradiance; atmosphere-ocean interactions, instead of carbon dioxide and other greenhouse gases, are possible causes of temperature changes. Peterson makes many valid points but by contrast, other credible scholars report that global warming is caused by human activities. Therefore, with most of the research findings pointing towards the increase in the greenhouse gases, climate change and global warming are caused by a combination of factors.
While study show the future debate that the current raise in global temperatures are not unusual as they have been experienced in the past. Goldstein claim that global warming is brought about by human activities; that it is manmade.
Contrary to what the society points out, research has shown that GHGs, especially carbon dioxide has been the lead cause for increase in global temperatures. According to Goldstein, all GHGs have been on the rise within the atmosphere since the beginning of the industrial revolution. ‘The awareness that Earth’s climate might be responsive to the atmospheric concentrations of gases that generate a greenhouse effect is more than a century old’. Due to their nature, these gases in the atmosphere absorb some of the solar energy as well as thermal energy radiated from the earth; a factor that leads to trapping heat energy (WMO). It would suffice to say, as already indicated by research, that further increases in the level of these gases in the atmosphere would translate to more heat being trapped within the atmosphere.
According to Mark Maslin GHGs emitted from industries and combustion engines have been listed to include carbon dioxide, Sulfur dioxide, nitrogen dioxide, methane and CFCs. Thus as pointed out by UN IPCC, the rise in carbon dioxide and other GHGs in the atmosphere, has directly led to the increase in heat trapped within the planet’s atmosphere. The rise in atmospheric carbon dioxide, as are all other GHGs, has been attributed to increased human activities that emit the gas as part of their byproducts according to Fleiming, 2008. Therefore, most of the GHGs are all released into the atmosphere due to the burning of fossil fuels which include crude oil and coal which contributes to the fact that global warming is not manmade. Moreover, the use of this nonrenewable type of energy causes emission of various GHGs including dioxides of sulfur, nitrogen and carbon. Additionally, gradual rise in the global temperature have been pointed to begin the start of the industrial revolution in the 18th century, when the demand for energy grew to accommodate more economic development. The use of fossil fuels began at this time as pointed out by Maslin, leading to gradual increase in the global composition of GHGs.
Peterson’s asserts that global warming is caused by natural processes and not only manmade activities. The fact that there is an increase of carbon dioxide emissions in the environment today is an indication that the human activities are causes of global warming. Statistics explicitly demonstrate that thee emissions of gases by vehicles in the environment are other causes of global warming. With advancing industrialization, greenhouse gases contribute to climate change in the world. According to the IPCC reports, greenhouse emissions increased during the preindustrial era and since then, there has been an increase in the of carbon dioxide by 30% ; that is from 278-358 ppmv. For the case of Methane, it has risen by 2405 from 700-1721ppbv. Consequently, this increase strengthens the idea that greenhouses effect causes global warming in the world. With this understanding, Petersons arguments can be opposed by that global warming is purely man-made.
In addition, Peterson’s idea that global warming is stimulated by natural processes is unsuitable. The claim that carbon dioxide is cannot be blamed as the cause of global warming climate change is dismissed by research findings by the UN IPCC. The organization established that the methane and carbon dioxide have higher ability to contain significant amounts of heat energy within the atmosphere. More so, carbon dioxide has been found to directly correlate to the temperature rises by the IPCC, particularly with the increased release of more carbon through deforestation and mass destruction of all carbon sinks around the world. On the contrary, Peterson opposes the organization reports of being one sided; a position that holds little strength in view of the overwhelming statistics indicating otherwise as illustrated by the IPCC .
