â€Å"Up and down, up and down – that is how temperature and climate have always gone in the past and there is no proof they are not still doing exactly the same now. In other words, climate change is an entirely natural phenomenon, nothing to do with the burning of fossil fuels† (David Bellamy). To what extent do you agree with this statement? The idea of climate change, for many, is an opinionated subject with much discussion of whether it is a real issue or just a natural phenomenon. However in recent years it is clear to see that trends in the Earth’s climate and surface temperature has spiked to levels never seen before. Despite all the evidence of the high levels of greenhouses gases and the rise in temperature, many still believe that†¦show more content†¦Nevertheless several lines of evidence show that current global warming cannot be explained by changes in energy from the sun, as if the warming were caused by a more active sun, then scientists would expect to see warmer temperatures in all layers of the atmosphere. Instead, they have observed a cooling in the upper atmosphere, and a warming at the surface and in the lower parts of the atmosphere. Thats because greenhouse gasses are trapping heat in the lower atmosphere. Therefore it is highly unlikely that the change in solar output has caused the climate change experienced on Earth. Volcanic activity has also been associated with climate change as volcanic eruptions release gases and particulates into the atmosphere. Eruptions large enough to affect climate occur on average several times per century, and cause cooling, by partially blocking the transmission of solar radiation to the Earths surface, for a period of a few years. The volcanic eruption in Iceland, Eyjafjallajà ¶kull, in 2010 is thought to have released enough ash and gas to cause a change in the Earth’s climate. In spite of this, the data shows that the change in the climate caused by volcanic activity is only short term, and therefore cannot be to blame for the trends that we are experiencing on Earth over the last century. Regardless of how climate change has been caused, there is clear evidence that it is a real issue.
