“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 Discuss the extent to which you agree with this statement. (40 marks) Climate change is often considered either a real issue or simply a natural phenomenon. However it is clear that recent pattern in the Earth’s temperature and climate has risen to that which has never occurred before in history. Even the extensive evidence that high amounts of greenhouse gases do have an impact on the rising temperature many still think all of this is part of the Earth’s natural cycle. During the last century temperatures have increased on a global scale, known as global warming. There has been a sharp rise in average temperature being 0.7°C between 1900 and 200. Scientists believe that this rise in temperature is mainly due to human factors and the increase of industrialisation and the revolution. These industrial activities have raised atmospheric gases such as carbon dioxide which contribute to greenhouse gases. The extra amount of these gases mean there is a thicker layer, meaning the gases absorb outgoing long-wave radiation which traps in too much heat. Increasing amounts of CO₂, methane, nitrous oxide, water vapour and ozone all contribute to this. The main cause in this rise is the burning of fossil fuels such as coal, oil, natural gas and petrol. Since the industrial revolution the levels of atmospheric CO₂ have increased from 280 parts per million to 380ppm for the past 10,000. Globalisation has also had an effect to some degree on the climate, as third world countries have been able to develop due to the cheap and easy access to fossil fuels, they now have the technologies to
