The climate change debate and governments

Final essay

Nowadays, famous scientists such as Nicholas Stern or Trenberth, claim that climate changes are in the heart of big debates. An example of that is the current conference in Copenhagen, Denmark, and this is what people consider as the biggest and most important environmental discussion there has ever been. The main factor for theincrease of climate change is the Greenhouse effect which has a direct impact on the human’s life. The Greenhouse effect is a natural phenomenon which leads to a warming of the planet (Oxford dictionary). As a consequence, the increase of global temperatures entails climate changes (Copenhagen consensus).

At the present time, some people think is more important to focus on other priorities such aseconomic recession, however, there are several reasons showing why addressing climate change should be a priority for every governments. A major reason is because of climate change, according to scientists, has a direct impact on the human life and also the world economy; another reason is that natural disasters are more and more violent and frequent. Moreover public opinion has shown moreinterests in climate debates.

Firstly, one of the main reasons why every government should address climate change as a priority is because climate changes will affect people’s life in different part of the word but it will especially have an impact on the world economy. Indeed, according to Sir Nicholas Stern in his review “The economics of climate change”, our economy which is based on theglobalization’s system (import/export of goods) will be affected because of changes of our environment and the lacks of water. Climate changes will also have a wide range of effects on the agriculture, which will affect the food productions. Crops and forests across the world are threatened by an increase of 17% bigger possibility of fires in 2020 as reported by Stern Review. According to Munich Re groupin “Natural Catastrophes 2004”, the 2003 European wildfires are essentially due to global warming which have led to a lost of 15 billion of US$ per year because of the crops destruction. Another issue is that it will affect the pollination which is essential for reproduction of species and for sustained agricultural productions. As a result of pollination decrease, the International Panel onClimate Change has estimated an economic downfall worldwide at 30-60 billions of US$.
In accordance to Professor JBC Jackson, rising of acidification of oceans is due to an increase of carbon dioxide (greenhouse effect) which has already had an impact on the fishing industry. According to Food and Agriculture Organisation of the United Nations, one billion people worldwide rely on fish as theirprimary source of animal protein and 2.9 billion people need this. Furthermore, in accordance with the SOFIA, An estimated 43.5 million people are directly involved, either full or part time, in capture fisheries and aquaculture. So, in order to limit impacts of climate change on the world economy, governments should address more regulations together.

In recent years, extreme weather events have hitours continents. According to Trenberth who is professor in the National Center for Atmospheric Research of the United States, said in the Policy Department Economic and Scientific Policy of the European Parliament: “it is likely to have more intense wind and produce more rainfall than without global warming during hurricanes”. This phenomenon is due to rise of sea surface temperatures which aremore determinant for strength of storms and produce more water vapour and so, more energy (WHO, Trenberth, 2005). So this phenomenon is influenced by the climate change. There is also a theory is that the climate changes has affected the dry and warming stream phenomenon called “El Niño” along the Latin America coasts. As reported by the National Oceanic and Atmospheric Administration (NOAA),...
