What greenhouse gas has over 100x the efficiency of carbon dioxide to reflect light back to the earth?
A methane molecule has 25 times the global warming potential of a CO2 molecule. A single nitrous oxide molecule has 298 times the global warming potential of a CO2 molecule.
Which of the following contribute the most to global warming?
In the effort to understand and address global climate change, most analysis has focused on rapidly rising emissions of carbon dioxide (CO2) and options for reducing them. Indeed, carbon dioxide, a byproduct of fossil fuel combustion, is the principal greenhouse gas contributing to global warming.
Is water Vapour a more potent greenhouse gas than carbon dioxide?
Andrew Dessler and colleagues from Texas A&M University in College Station confirmed that the heat-amplifying effect of water vapor is potent enough to double the climate warming caused by increased levels of carbon dioxide in the atmosphere.
What percentage of the total greenhouse gas effect is caused by man made carbon dioxide?
Global Manmade Greenhouse Gas Emissions by Gas, 2015 CO2 accounts for about 76 percent of total greenhouse gas emissions.
Why is water vapor considered a greenhouse gas?
Water vapour is also an effective greenhouse gas, as it does absorb longwave radiation and radiates it back to the surface, thus contributing to warming. When compared to other greenhouse gases, water vapour stays in the atmosphere for a much shorter period of time.
Which of the following best describes why water vapor a greenhouse gas is not considered a significant contributor to global climate change?
Which of the following best describes why water vapor, a greenhouse gas, is not considered a significant contributor to global climate change? Water vapor is inefficient at absorbing heat and does not absorb much of the infrared spectrum.
What is the most common source of carbon monoxide?
Most Common Carbon Monoxide Poisoning Sources
- Gas space heaters.
- Furnaces and chimneys.
- Back-drafting.
- Gas stoves.
- Generators and other gasoline-powered equipment.
- Automobile exhaust from attached garages.
Where does carbon monoxide sit in the air?
Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance.
