Technical report on global warming WJR Alexander Professor Emeritus‚ Department of Civil and Biosystems Engineering‚ University of Pretoria‚ South Africa. Email alexwjr@iafrica.com 23 November 2005 I have just completed my technical report An assessment of the likely consequences of global warming on the climate of South Africa. (The extended summary of the report is now available. It consists of 92 pages‚ 14 tables‚ 16 figures and 50 references.) The conclusion is that there are no scientifically

Global warming what is it? Global warming refers to an average increase in theEarth’s temperature‚ which in turn causes changes in climate. So what’s the big deal you ask? Well the big deal is‚ if temperatures rise above normal levels for a few days‚ it’s no big deal‚ the Earth will stay more or less the same‚ but if temperatures continue to rise over a longer period of time‚ then the Earth may experience some serious problems! What causes global warming? The Earth’s atmosphere contains gases that

Global warming to some individuals is something fake that others say. However‚ global warming is a threat to us. Most people think of this as a scientific fantasy‚ but it can be a huge danger for later generations. We can’t be egocentric and only think about us. Global warming isn’t only effecting us‚ but it’s also effecting animals. Some species might even go extinct because of global warming. We need to do something to prevent or at best slow the process down a bit. I believe it’s vital that we

Global Warming And Climate Change – An Issue Over the past ten years global warming and climate change has become an issue. Although is it an issue that people need to be concerned about? I believe that it is something that humans should pay attention to and be concerned about‚ but I feel that we have no impact or control over this issue. Instead of blaming people we should pay attention to the sun making a difference on global climate then maybe it could prove that it has a bigger impact than

‘The Implications For Health In Global Warming’ This essay will discuss global warming and the degree to which it will negatively affect people’s health and well being. Negative global warming related health effects will vary greatly due to geographical location and socio-economic status. Generally developed countries will be far better placed to confront the health challenges of climate change‚ than the developing word that already experiences a lower average state of health and less developed

GLOBAL WARMING AND IT’S EFFECTS ON GLACIERS Global Warming The average global temperature has raised more than expected in the past few decades. Many prefer to use the milder term ’climate change’ instead of the harsher ’global warming’ to describe this change in average global temperature. The main cause of global warming is thought to be the ’greenhouse effect’ that is mainly caused by us humans. With an increase in temperature glaciers worldwide are melting faster than the time taken for

People are all carrying an umbrella when they step out of house as they cannot stand the blistering heat. This is caused by global warming‚ isn’t it? Global warming has resulted many negative effects and they are mainly caused by human activities. Hence‚ we‚ humans should stop global warming. Human activities produces 75% of annual carbon dioxide emissions. Firstly ‚the greenhouse gases has caused temperatures to increase. Since 1861‚ the average temperature has increased by 0.6 Degree Celsius

A GLOBAL PROBLEM: RESPONSIBILITY FOR CLIMATE CHANGE Climate change is a tangible problem and its existence can no longer be denied. It is one of the most important scientific‚ economic threats facing to the earth. There are many factors lead to climate change‚ such as greenhouse gases‚ carbon dioxide‚ fossil fuels. Although it would be self-deception to believe that humans had nothing to do with it‚ the fact is that human activities caused negative effects on climate change. More people exploit

Global warming Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane) trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. This hurts many people‚ animals‚ and plants. Many cannot take the change‚ so they die. The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat

is a problem that is affecting americans right now. Whether it means increased flooding‚ greater vulnerability to droughts‚ more severe wildfires--all these things are having an impact on americans as we speak.” - U.S. President Barack Obama. Global warming is an issue filled to the brim with side effects‚ spilling all over the world right now. When people talk about it‚ they seem to take it a lot lighter than it is truly. It is causing more extreme weather‚ including droughts‚ hurricanes‚ floods
