Global Warming Paper


Why is Climate change a natural rather than a man-made process?

Global warming, natural or manmade?
There has been a number of contradicting arguments whether global warming is caused by man or not. Throughout this article I will argue for why the current change in global climate could not, in any way, have been caused by human activity. I will go over the points which prove that global climate change is all natural and the reasons why assuming that we have caused it are unrealistic. In the following paragraph I will look at how climate change has changed in the past and how that proves we are not the cause of todays global warming. 

The primary reason for which we know that it is impossible for human activity to be playing a role in the current rise of temperatures is the fact that the earth has always been experiencing a change in climate, it is just the way the our planet adapts. Rising temperatures have been present long before human existence and have allowed for the development of complex organisms to exist on our planet now. Not only have there been rising temperatures but falling ones too, there were numerous ice ages in the past which simply serve to show that what we are experiencing now is all natural. As there were higher temperatures long after the ice ages, we can only assume that the earth is simply warming up. It is common sense to anyone and everyone that this is the cause of what we are experiencing today. More than half of the population in developed countries know that global is a natural phenomenon, hence there is no reason to worry. The thermal maximum was in fact experienced between the Palaeocene and the Eocene which was around 55 million years ago, where the average temperature of the ocean was 3x as high as ours (14 degrees celsius). 

Secondly what scientists assume is that the rise in temperatures is caused by the higher concentration of greenhouse gasses which are released into the atmosphere by the human population, mostly by the burning of fossil fuels. However simply because gasses such as carbon dioxide absorb heat and there is a higher concentration of them in the atmosphere, scientists are wrong to assume this is the direct link to global warming. It is wrong to assume that the use of cars or agricultural breeding of cows is what will destroy our planet. They are wrong to assume so because CO2 is in fact great for plant life and has (similarly to temperature) carried greatly throughout the history of our planet. Just like temperature it has carried however not accordingly. Throughout history there is no clear link between gasses like CO2 and the overall temperature of our planet. Besides that, there has always been a layer of greenhouse gasses in our atmosphere as it is a vital component that allows life of earth. Besides  this, there was a large increase in CO2 emissions in the atmosphere after the second word war, however there was a fall in temperatures recorded for a long 4 decades after that. The evidence contradicts itself hence why it is a myth that human activity is melting glaciers and killing the ecosystem.

Lastly I will focus on what scientists intentionally miss most of the time. Which is the suns activity, after all the primary source of heat in our galaxy is the sun. They all spend too much time focussing on human activities whereas in reality they all should be looking at the one thing which is the source of almost all heat, the one thing without which we would not be able to survive at all. Which is the sun. Again throughout the past, increased activity on the surface of the sun has shown an increase in the earths temperatures. Solar activities are believed to vary, on average, in 11 year cycles. A more specific factor in which a clear correlation between global temperature can be seen is the change is solar radiation. Changes in solar wavelength is believed to have a higher kinetic energy. However again the scientists have not been focussing on solar radiation changes and therefore do not know much of what this could mean for our planet. For all we know, solar changes could be the end for planet earth. Not only does the radiation impact the earth's temperatures but so do solar flares. There is a peak in these solar flares, called the solar maximum, which is achieved every 11 years or so. This can be a large contributor to global warming since these solar flares are very high in kinetic energy as well as in magnetic activity. 

In conclusion I believe it is not up to us, the citizens, to be worried as to what contributes to global warming. The real reason lies in the research being carried out by our scientists. In order for us to understand what further steps to take we have to firstly know what is causing this rise in temperature. As of right now, we can assume that this is all natural and will not further affect the human population. We can stop worrying and take further actions once they, the scientists, give us a direct link as to what is causing global warming and whether this is even a threat. Let alone if the precautions we should be taking will even help reduce the temperatures and whether even that is good.
