Global Warming Explained by Jonathon Hardcastle
Global warming is thought of as one of the biggest threats to world security in modern times, and it is arguably already taking its toll in our weather system. By a combination of natural cyclical progression, and the impact of human behaviour and activity over the last century, the Earth is steadily seeing the effects of the global warming phenomenon. But what exactly is global warming, and exactly what impact could it have on our environment?
Global warming can be defined as an overall gradual increase in world temperature over time. This is measured by averaging Earth and Ocean temperature, and has shown a steady upwards trend over recent decades. Furthermore, it is thought that over the last half a century, this has been a result of human civilisation and industrialisation. One of the major contributors to global warming is what is known as greenhouse gas, which comprises largely of carbon dioxide from general human activity.
Global warming as a process is thought to be highly devastating in terms of its effect on the climate. 'Climate change' is a phrase which is often use in association with global warming, and it has potentially catastrophic consequences for the world in which we live. 'Climate change' also covers global cooling, which can also occur as a result of human activity and greenhouse gases, and reflects a substantial change in the world's climate, which could change our habitat beyond recognition. This could be characterised by unusual weather patterns, resulting in more frequent natural disasters, which could in turn lead to political and social chaos in the decades and centuries to come.
There are a number of international political treaties which have been set up to change the progress of global warming, although their tangible upshots still remain to be seen. Through political cooperation, it is hoped that environmental targets can be met on an international scale, to make a real difference to the environment. However, at a personal level, there is significant scope for helping, rather than hindering the world in which we live, including recycling household waste, and reducing personal carbon emissions.
Global warming is arguably one of the biggest threats to human civilisation, and it is something which requires a drastic change in lifestyle to reverse. However, with a personal and political impetus, it is hopeful that the damage done to the planet can be reversed for future generations to enjoy
