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
Premium Global warming Carbon dioxide Greenhouse gas
Global warming is called the greenhouse effect because the gases that are gathering above the earth make the planet comparable to a greenhouse. By trapping heat near the surface of the earth‚ the greenhouse effect is warming the planet and threatening the environment. Many scientists criticized Mr. Hansen’s report‚ and the debate over global warming continues today. Current fears stem largely from the fact that global warming is occurring at such a rapid pace. Models are predicting that over the

PLAN Ways to Slow Down Ozone Depletion Global warming refers to an increase in the average temperature of the Earth as a result of the greenhouse effect‚ in which gases in the upper atmosphere trap solar radiation close to the planet’s surface instead of allowing it to dissipate into space. Both natural and human-made conditions can contribute to global warming‚ but human beings can do several things to reduce the effects. The biggest cause of global warming is the carbon dioxide released when fossil

Global warming is currently the most controversial issue.The debate over global warming has been going all around the world and it seems endless. Depending on one’s political view‚ whether a person is a liberal or a conservative may consider global warming as the biggest challenge facing humanity or one may dismiss‚ saying it is not real or may simply claims global warming is a hoax. However‚ there are strong‚ credible evidences that indicate the extreme and unpredictable weather pattern we have

the only planet we can live in and it’s the only planet we have so we have to take care of it. Knowing this we are still hurting it‚ whether it is through degrading the soil or through CFC’s. Global Warming is real and its hurting our environment and it’s entirely our fault. It’s true that Global Warming happens naturally however because of the human race we have increased how fast it’s happening. There have been many meetings with other nations to control the amount of carbon-dioxide released.
Premium Greenhouse gas Earth Global warming
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

the hysteria‚ all of the fear‚ all of the phony science‚ could it be that man-made global warming is the greatest hoax ever perpetrated on the American people? It sure sounds like it‚” said James M. Inhofe a member of the U.S. Senate. Could this be the true? Many facts behind the controversial issue of global warming prove this statement to correct. Global warming is not caused by human activities. Global warming cannot be completely caused by human’s emission of greenhouse gasses.” In the last

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
