global warming and its affects

Extracts from this document...

Introduction

Climate change affects us all. Climate change is now happening at a much faster rate than before due to more countries developing industrial revolutions. This means that additional countries will be using carbon-emitting machines. The changing climate is a steady rise of temperature and the earths heat is predicted to continue to increase. This is known as Global Warming. There is a lot of evidence supporting the fact that the climate is changing. There are a variety of sources, which can be used to restructure precedent climates. Most of the evidence discovered are natural, indirect indicators that reflect the climate. These include vegetation, pollen analysis, ice cores, sea level change and glacial retreat and geology. Data has been collected proving that the climate is changing globally by stating the increase in temperature (see figure 1). The clearest sign that our planet is heating up are the disappearing Glaciers. Ice has always been melting around the world but, if present warming trends continue, every glacier in Glacier National Park could have melted by 2030. Storms are on the increase; the global frequencies of high winds are greater than ever. Tropical Storms also seem to be escalating. This is linked to the oceans rise in temperature. This has meant that floods have been on an increase as well. The green house effect is occurring all the time. ...read more.

The rainfall could decrease over Southern Europe, Australia and the nothern part of South America. But this could also be the complete oposite in some situations. The sea level has been rising in every ocean (see Figure 3) and in some areas flooding could be a major issue. For every one degree the sea heats up by the sea level rises by two meters. Another spin-off effect is the increased rainfall in Central Africa, East Asia and Eastern South America. The I.P.C.C. predict that by 2025 the number of people living in areas where water is sparse will grow from 1.7 billion to 5.4 billion. Of course, the rise in temperature will mean that glaciers and ice caps will melt. But the common misconception of this is that this will cause the sea level to rise. It doesent because most of the ice is under water at icebergs and sea ice. This would mean that the ice that has melted will displace the ice it was before as it does not disapear once melted. Only a tiny part of the percentage of ice actually causes the sea level to rise. Global warming could also influence ocean currents which could effect countries by a change in temperature. Disease would increase, for example the warmer environment means that mosquitoes would become more active and spread more disease around through blood. ...read more.

Conclusion

Several companies deforesting in the tropics have decided to make it a sustainable business not just for the environment and reducing climate change but also to make it a more profitable business. There are are also lots of things you could do youreself to help stop global warming. Recycling is the easiest way to renew waste. Using sustainable transport is great for preventing the unneeded use of the car and is nearly always cheaper. You could share a lift to work or even better, cycle to work. Using public transport is better than using the car. It is very important that you don't waste energy in your home as most homes create more carbon dioxide than the average car. The fact is that houses are not very energy efficient, but we can change that. You can insulate your house more effectivly and that way you wont need to use the heating as much. Take a shower instead of a bath to preserve warm water. There are also many other ways to save energy but you could also use a renewable energy like solar power. To summarise climate change is one of the most important issues that the world has to deal with today. It's not just humans that influence the climate but also animals and plants. Global warming will almost certainly have life threatening effects on the world. Above is a graph (see Figure 4) showing you just what has happened to the climate. If this continues, the predictions will become real. Axel Larsson ...read more.
