Nature of Science, J. Terfil All these are increasing our numbers, making our houses warm, and decreasing the chance that we will die prematurely. As the success of humankind suggests, the more knowledge we have about the world around us, the more equipped we are to make changes and advance. Thus it is necessary to examine the issue of climate change from a scientific and unbiased point of view. There is much to be said about the climate change phenomenon, but the best way to go about the examination of the matter is by starting with the simplest explanation.
The atmosphere is a protective layer of gasses surrounding the earth. It is transparent and therefore admits the radiation coming from the heated surface of the sun oC , which provides warmth and light for the survival of all living organisms on the planet.
The atmosphere is not as transparent to this infrared energy and thus water particles and CO2 retain it, not permitting it to radiate out into space Nature of Science, J. There is a necessary amount of carbon dioxide in the atmosphere, but once its balance has been disturbed by introducing excessive quantities of greenhouse gases, nature begins to act out in unexpected and dangerous ways, causing hurricanes, floods and other events which endanger life on earth.
All these issues make climate change a topic of great importance to society and the scientific world. His formulation of the concept set the stage for further research and nearly four decades later an Irish colleague of Fourier, John Tyndall explored the retention of infrared energy by CO2 and water particles.
This discovery contributed to the building up of the concept of climate change, but it was not until that the issue of the human impact was raised. A timeline of climate change science, www. It was the Swedish chemist Svante Arrheinus who first suggested that climate change was a man-made phenomenon.
While he proposed that the increase in coal burning of would raise the amounts of carbon dioxide contained in the atmosphere and thus raise temperatures, he considered this a desirable event in light of the threat of another ice age. The first statistical comparison of temperature and CO2 levels was carried out by Guy Stewart Callendar in His research yielded conclusive results.
It showed that there was a ten percent increase in levels of CO2 over the past century, and that average temperatures had risen noticeably. The year was an important milestone in the development of climate change science, Professor Gilbert Plass proved that increased carbon dioxide content in the atmosphere could cause temperature increases. In the same year chemist Hans Suess detected the fossil carbon produced when burning fuels.
The measurements showed a visible increase and lead to the formation of the Keeling graph, which is used to this day to document increases in levels of carbon dioxide. A timeline of climate change science, cnn. Prior to the documentation of the hottest year to date in , the scientists at the World Climate Program conference in Austria predicted that the continued increase in CO2 emissions would cause a significant rise in the mean surface temperatures of the planet.
In it he stated that computer models and temperature models unambiguously prove that the human caused greenhouse effect is already underway. Shortly after this, the IPCC presented its first report, which predicted a 0. In light of all these events there were a number of summits and attempted regulations of the level of emissions each country is allowed to produce.
Results were not significant, as it was necessary to sacrifice some of the economic prosperity of developed countries in order to achieve emission targets. Almost all conclusions in the field of climate change are linked to experimentation and scientific discoveries. His hypothesis was that light and heat radiation have the same properties and that gasses in the atmosphere absorb radiant energy. He was the first to measure the absorption potential of water vapour, CO2, oxygen, etc. Irish Physicist, Naturalist, and Educator.
These two hypotheses have been proven time and time again and emphasise the human impact on climate change and how it is progressing. The findings of Tyndall and other researchers in the field are constantly subject to speculation and intended refutation.
Nature protectionists and sustainability specialists focus primarily on the human contribution to global warming, and what science can do in order to save the environment. This approach seems to be the most appropriate, because it provides humanity with the chance to analyse and amend its actions and find solutions. This direction of thought is however highly dependent on a misconception about the nature of science, namely that science is eventually capable of answering all questions, providing solutions for all problems Misunderstanding the Nature of Science MSTA Journal Spring, This is untrue especially when dealing with human beings.
Science might have gotten us so far, but it is unlikely that it will be able to provide us with an appropriate course of action in salvaging the climate. There are many non-testable aspects of human behaviour and social structure. Science can help, but it will not be able to provide an answer to the climate crisis, because it is primarily of social character, thus, science does not have an answer to all questions. Another misconception about the nature of science which we may disprove in the context of climate change is that science can only confirm events which have been observed unfolding Misunderstanding the Nature of Science, Our temperature depends on both these factors.
The point is that when the heat reaches the Earth and then is reflected back to the atmosphere, the certain amount of it is stopped by the so called greenhouse gases. They are vital for keeping the right amount of heat on the Earth so that all the living creatures can exist on our planet.
However the increasing amount of it changes the average temperature which can lead to unprecedented changes in our climate. The greenhouse gases include water vapor, carbon dioxide, methane, and nitrous oxide. Their number has increased due to burning of fossil fuels, which has become the primary source of energy for people nowadays.
It is difficult for most of us to understand why a slight increase in the average temperature on the planet can somehow influence us. In addition, such climate changes can result in longer period of droughts in some regions, the increasing number of wildfires, and the bigger number of tropical storms. That being said, we are going to make an in-depth analysis of all the factors that cause the greenhouse effect, the consequences, including the potential ones, and the ways of solving this problem.
