Since the Industrial Revolution, humans have been releasing larger quantities of greenhouse gases into the atmosphere. In the past century that amount has increased dramatically, with the knock-on effect of global warming. Global temperatures have accelerated in the past 30 years and are now the hi...
What are Greenhouse Gases ?Gillenwater, Michael
The definition of a greenhouse gas is at the same time very simple and very complicated for the ordinary man (or woman !) : such a gaz is “just” a gas mixed in the atmosphere thatabsorbs the infrared radiation emitted by the earth’s surface. We are not accustomed to these gases bec...
Fluorocarbons.The fluorocarbon gases that contribute to the greenhouse effect include chlorofluorocarbons, or CFCs; hydrofluorocarbons, or HFCs; perfluorocarbons; and sulfur hexafluoride. They are commonly used to provide refrigerants. While each gas constitutes a tiny proportion of greenhouse gases, thei...
1. Definition of Greenhouse Gases (GHGs): Greenhouse gases are gases in the Earth's atmosphere that have the ability to absorb and re-radiate infrared radiation. This process contributes to the greenhouse effect, which leads to global warming. 2. Mechanism of Action: The key characteristic of ...
"natural" greenhouse effect that keeps the Earth's climate warm and habitable. There is also the "man-made" greenhouse effect, which is the enhancement of Earth's natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels (mainly petroleum, coal, and ...
The atmosphere is the layer of gases that surround the earth, and it provides the air that we need to stay alive. Although the majority of the atmosphere is made of nitrogen and oxygen, there are other gases found in trace amounts that are known as greenhouse gases....
Here we shall learn what the greenhouse gases are, how it is emitted by human activity and also how to reduce such emissions.They are Carbon dioxide , Methane, Nitrous oxide, Some industrial gases such as hydro fluorocarbons, Per fluorocarbons, Sulphur h
Greenhouse gases are naturally occurring gases, such as CO2, methane, and sulfur dioxide, that trap heat on Earth—like a greenhouse traps heat to grow tomatoes in cold climates. According to NASA, without greenhouse gases, the average temperature on Earth would be 0°F (–18°C), rather ...
Even if we didn’t have greenhouse gases, were going to have to move away from fossil fuels, as we’re going to run out. They’re finite, whereas solar and wind are infinite. ~Ted Turner Consequences of increased levels of greenhouse gasses due to human activity ...
