Examples of greenhouse gases in the following topics:
-
- Greenhouse gases are probably the most significant drivers of the climate.
- When heat energy from the sun strikes the earth, gases known as greenhouse gases trap the heat in the atmosphere, similar to how the glass panes of a greenhouse keep heat from escaping.
- The greenhouse gases that affect earth include carbon dioxide, methane, water vapor, nitrous oxide, and ozone.
- Greenhouse gases, however, reflect much of the thermal energy back to the earth's surface.
- Greenhouse gases, as they absorb and emit radiation, are an important factor in the greenhouse effect, or the warming of earth due to carbon dioxide and other greenhouse gases in the atmosphere.
-
- The greenhouse effect is an elevation in surface temperatures due to atmospheric gases absorbing and re-radiating thermal energy.
- Gases known as greenhouse gases, including water vapor, carbon dioxide, ozone, and methane, absorb and trap this heat as it tries to escape from the atmosphere.
- Greenhouse gases then re-radiate this energy back to Earth, elevating atmospheric temperatures even when the surface is not being directly irradiated by the sun.
- The cloud layer can also absorb infrared radiation and contribute further to the greenhouse effect.
- This increase in greenhouse gases is producing the phenomenon known as global warming, a rapid increase in atmospheric temperatures that may produce a number of environmental consequences, such as more extreme weather.
-
- Greenhouse gases raise the Earth's equilibrium temperature by absorbing radiation that would otherwise be emitted into space.
- The 9°C discrepancy is due to the greenhouse effect.
- The gases in the atmosphere, primarily CO2 and water vapor are highly absorbent in the infrared part of the spectrum.
- On the other hand, greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are characteristically strong absorbers of the energy radiated by the Earth's surface.
- (If greenhouse gases increase, then temperature increases, and higher temperatures cause the Earth to radiate more, compensating for the greater energy absorbed in the atmosphere. ) With light radiation, we find the entropy carried by the photons decreases as temperature increases, $S \propto \frac{1}{T}$.
-
- The Earth's atmosphere is a layer of mixed gases that is trapped near the surface due to gravitational forces.
- In the 1800s, scientists, including John Dalton, realized that the atmosphere was composed of a variety of gases.
- These minor components are the major contributors to phenomena like weather, the greenhouse effect, and global warming.
- Carbon dioxide, water vapor, and other greenhouse gases are adept at stopping heat from leaving the atmosphere, causing the Earth to heat up.
- Some greenhouse gases are beneficial—without them, Earth would be as cold as the moon—but the recent increase in carbon dioxide has upset the precise balance between too cold, too hot, and just right.
-
- This warning of the climate system is unequivocal, and scientists are now more than 90% certain that it is primarily caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels.
- The ranges of these estimates arise from the use of models with differing sensitivity to greenhouse gas concentrations.
- Parties to the UNFCCC have adopted a range of policies designed to reduce greenhouse gas emissions and to assist in adaptation to global warming.
-
- The 2010 United States federal budget proposes to support clean energy development with a 10-year investment of US $15 billion per year, generated from the sale of greenhouse gas (GHG) emissions credits.

- This diagram shows how the greenhouse effect works.
- Some of the infrared radiation is absorbed an re-emitted by heat-trapping "greenhouse" gases in the atmosphere.
-
- One aspect that has been identified as important in slowing down climate change is the reduction in greenhouse gases, also referred to as carbon emissions.
- This is a market-based system that would see limits, or caps, set on the amount of greenhouse gasses that could be emitted.
-
- Unlike a cap-and-trade system, which allows markets to stipulate the amount of emissions that are tolerated (and which allows for the price of carbon to vary), a greenhouse gas tax would set a fixed price and let it determine the amount of emissions put forth.
- In other words, the higher the tax on greenhouse gases, the greater the incentive to reduce emissions.

- The greenhouse effect: an elevation in the Earth's surface temperature due to the absorption of electromagnetic radiation by atmospheric gases.
-
- Volcanoes can cause environmental damage due to the hot lava, ash, and gases that are released during an eruption.
- Volcanoes can also cause more delayed damage through the gases and particulate matter that are released into the atmosphere.
- Carbon dioxide is a greenhouse gas, and sulfur dioxide, hydrogen chloride, and hydrogen fluoride are all components of acid rain.
- Often, eruptions are preceded by an earthquake or the release of new gases from the volcano.
- Recall that volcanoes release toxic gases, including sulfur dioxide, hydrogen sulfide, hydrogen chloride, and hydrogen fluoride.
