Global warming means a gradual increase in the Earth’s average lower atmosphere due to emissions and build up of greenhouse gases . Global warming is when the earth heats up and the temperature rises. It happens when greenhouse gases such as carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. Greenhouse gases are released mostly by the burning of fossil fuels for transportation‚ heating‚ electrical

Many people wonder if global warming is happening at all and if it is happening‚ can it really hurt us. Many scientist claim that the human race is to blame for global warming‚ while others claim that the human race

Global Warming Global warming is the rise in temperature (warming) of the entire planet and oceans. The rising temperatures affect our climates in such that droughts will happen more often‚ deserts will become bigger‚ heat waves will happen more often‚ and snow will lessen in areas. Also storms and hurricanes will happen more often. Global warming happens very slowly‚ the environment goes through natural periods of cooling and warming. Global warming causes changes in the

Global warming You have probably heard about the phrase “global warming” hundreds of times. But what exactly does global warming means? Global warming is not about having a hot day or week or month in one part of the world. It has to do with the average temperature worldwide. Simply put‚ global warming is the unusual rapid increase in earth’s average temperature worldwide. The warming of the earth began in the mid 1800’s. In the beginning it was small and very slow but then in the 1980’s the

Global Warming Global warming ; a growing problem that affects people‚ animals and the environment all over the world. What is it and what can we do to stop it? What is global Warming? Many scientists are still arguing that the causes of global warming are natural and not humans fault. Their main statement is that in the past the earth’s temperature has declined and risen. This happened even before humans inhabited the earth. Some argue that the rotation speed and axis of the earth can

GLOBAL WARMING AND CLIMATE CHANGE Uzochukwu Chekwube BSC2011 Professor Bloodworth July 21‚ 2014 Global warming is still a debate between us. Most people do not believe that our world is warming up‚ they believe the climate is in a cycle‚ and that humans do not contribute to the warming of our climate. Research supports the fact that Global warming is a huge factor in climate change and that

Global warming W hat is global warming? The changes in the surface air temperature‚ referred to as the global temperature‚ brought about by the enhanced greenhouse effect‚ which is induced by emissions of greenhouse gases into the air. How Global Warming Works Carbon Dioxide (CO2) Fossil fuels (coal‚ oil‚ natural gas) Example of the Greenhouse Effect The Sun’s energy passes through the car’s windshield. This energy (heat) is trapped inside the car and cannot pass back through the windshield

January 14‚ 2013 Gases such as carbon dioxide‚ methane and nitrous oxide are sometimes called Greenhouse gases‚ are increasing into our atmosphere causing climate changes. Scientists call this climate change – Global Warming. Sea levels are rising‚ glaciers are melting‚ and storms are raging fiercer than ever before such as Hurricane Katrina in 2005 and Hurricane Sandy in 2012. As the Earth spins each day‚ the new heat swirls with it‚ picking up moisture over the oceans‚ rising here‚ settling

a moral issue‚ it is your time to cease this issue‚ and it is our time to rise again to secure our future‚” said former Vice-President Al Gore. Al Gore made a speech about global warming and said how to keep it healthy. The earth can be kept healthy and exist longer without global warming. Global warming is becoming a popular topic around the world. “Global Warming and the Greenhouse Effect” discusses what global warming is. This is how global warming is caused.

of the light energy from the sun is emitted in wavelengths shorter than 4‚000 nanometers (.000004 meters). The heat energy released from the earth‚ however‚ is released in wavelengths longer than 4‚000 nanometers. Carbon dioxide doesn’t absorb the energy from the sun‚ but it does absorb some of the heat energy released from the earth. When a molecule of carbon dioxide absorbs heat energy‚ it goes into an excited unstable state. It can become stable again by releasing the energy it absorbed.
