11: Global Warming
Global Warming The greenhouse effect, in environmental science, is a popular term for the effect that certain variable constituents of the Earth's lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the “ ...
12: The Greenhouse Effect
The Greenhouse Effect The greenhouse effect is another alarming problem that we have encountered through our own negligence. The earth's atmosphere consists of mostly nitrogen along with oxygen and small amounts of other gases. One of these gases, ...
13: Could the Greenhouse Effect Cause More Damage?
Could the Greenhouse Effect Cause More Damage? John Harte is an ecologist from the University of California at Berkley. He is trying to find out whether heat stimulates further trace-gas from solid or not. He is going to conduct an experiment that will tell him if the greenhouse effect could start a cycle that would cause the effects to be worse than already predicted. The experiment will begin December of 1996 and will run for no less than three years. Harte has ...
14: Greenhouse Gases And Consequences
Greenhouse Effect The greenhouse effect is a natural phenomenon that warms the earth and enables it to support life. Without it, the average temperature on earth would be around -18 degrees C, instead of the current +15 degrees ...
15: Fire 2
... days or hours. Climatologists use some of the same information to describe climate in various regions by figuring out the long-term averages for conditions like rainfall, humidity and temperature ([On- line], 1998). The Natural Greenhouse Effect On a planet with no atmosphere, the infrared radiation emitted by its surface would go straight out to space. But on Earth, things are very different. The Earth's atmosphere has several gases that have ... is captured before it gets out to space. As they absorb long-wave energy from the surface, these gases heat up, making the air warmer. This is roughly the same thing that happens inside a greenhouse on a sunny day, and why it is called the greenhouse effect. As you might expect, the gases that do this are called greenhouse gases ([On-line], 1998). The atmosphere's main greenhouse gases ...
16: Global Warming
Global Warming In recent years, the term global warming has been associated with such phrases as “impending environmental disaster”, the “greenhouse effect” and “the most serious environmental threat of the 21st century” (Newton xi; Newton 87). Global warming is defined as an increase in the average temperature on Earth. The increase was first detected in the 1980’s. The cause of global warming is believed to be the greenhouse effect. This is the process of trapping heat with the Earth’s atmosphere due to the presence of large amounts of carbon dioxide, chlorofluorocarbons, methane and nitrogen oxides (“Global”). Despite much media coverage of ...
17: Global Warming
... media. If anything comes from this project, it is a hope that it will shed some light onto the hot topic of global warming with some cold science! Global warming occurs when the levels of greenhouse gasses rise and less infrared light, or heat, escapes the earth's atmosphere. Thus, the temperature experienced on Earth begins to rise. Climate change is a part of the Earth's history. There have been ... 0.03% of the gas content within the atmosphere. However, it has a disproportionate impact on the earth's temperature. Thus, minor fluctuations in the percentage of atmospheric carbon dioxide will likely have a significant effect on the global temperature. The percentage of atmospheric carbon dioxide has risen over the past century at an alarming rate. Industrial civilization essentially driven by fossil fuels such as coal, oil, and gasoline all major ... cyclic nature of the carbon cycle, would change little if not for human activities that produce so much every year. The present addition of 3% annually to emissions is enough to throw off the balancing effect of the carbon cycle. The result is a build up of carbon dioxide in the atmosphere, which is currently at about a third higher than pre-industrial levels worldwide. Throughout the last century our ...
18: Global Warming
... the radiation of the sun was trapped in the carbon dioxide the temperature of the earth would increase by 1-2 degrees. In 1988 James Hanson, a respected scientist, told the U.S. Congress "the greenhouse effect is occurring now and it's changing global climate."(1989 Koral). After the 1900's people started making factories and started using fossil fuels like coal, oil, and aluminum. It was the industrial revolution and ... The Road Ahead With all these obvious scourges plaguing us now, it seems that things cannot get any worse. However, the current droughts, floods, and storms are just the tip of the iceberg. If the greenhouse effect continues unabated, then the inhabitants of Planet Earth have some surprises in store. Scientists estimate that the global temperature will rise between 5 and 9 degrees by the middle of the 21st century, ...
19: Greenhousing the Wrong Way
Greenhousing the Wrong Way Exactly what is the "Greenhouse Effect?" The "Greenhouse Effect" is the common name given to global warming. The effect is named so due to its similarities to the function of a greenhouse. Heat from the sun is allowed into our atmosphere, and ...
20: Rainforests
... them being very simple. One major reason is that the plants in the forest turn carbon dioxide into clean air, which helps us fight pollution. Also, by absorbing carbon dioxide, the rainforests help deter the greenhouse effect. The trees of the rainforest store carbon dioxide in their roots, stems, branches, and leaves. The plants and animals of the rainforest also provide us with food, fuel wood, shelter, jobs, and medicines. "Image losing ... night… …major climatic and other environmental changes will occur if this continues." (Costa Rica Rainforests Outward Bound School, 1996) The destruction of the rainforests cause carbon dioxide to be released, which in turn allows the greenhouse effect to occur. The greenhouse effect raises the temperatures all around the world, and can cause ice caps to melt. When ice caps melt, the sea level rises, causing major flooding around the world. ...
