What Are The Gases Of Greenhouse Effect
Since an understanding of greenhouse gases is important to understanding climate change and global warming, it is helpful to answer the question, “What are greenhouse gases?” And then dive deeper into the topic: How much is too much? Are they so bad for the planet? What role do they play in climate change? With this article, you will learn a definition of greenhouse gases, more about what greenhouse gases are, what they do and how they affect our world.
The Primary Problem With Greenhouse Gas Theory
Greenhouse gases refer to the gases that absorb and emit radiant energy in the thermal infrared range, which traps heat in the atmosphere. The phenomenon of trapping solar radiation and absorbing infrared radiation is known as the greenhouse effect – a term inspired by the greenhouses that often sustain life in colder months by absorbing radiant energy from the sun and retaining it in a glass enclosure. Thus, the greenhouse effect helps our planet stay warmer than it would be without an atmosphere.
To some extent, greenhouse gases like methane and nitrous oxide benefit the planet by creating a layer of protection that holds on to heat instead of allowing it to escape from our atmosphere. Without greenhouse gases, life would not be possible. The temperature of the planet would drop to below 0˚F, creating an inhospitable environment for plants and animals to survive.
However, the opposite is also true: if too many GHGs are in the atmosphere and greenhouse gas concentrations increase, the planet can become too warm. This influx of greenhouse gases is what many scientists believe to be the leading cause of climate change.
Greenhouse gases impact the planet in different ways, depending on their ability to absorb energy (their “radiative efficiency”) and how long they stay in the atmosphere (their “lifetime”).
The Greenhouse Effect And The Global Energy Budget
To help compare the global warming impact of the various greenhouse gases, a measurement called the Global Warming Potential (GWP) was created. The global warming potential measures how much energy the emission of 1 ton of a gas will absorb, compared to the emission of 1 ton of carbon dioxide (CO2) over a given period, usually 100 years.
The higher the GWP, the more that gas contributes to global warming compared to CO2 at the same time. By creating this common unit of measurement, analysts and policymakers can make accurate emission estimates for the various gases, and compare carbon emissions and reduction opportunities in different sectors.
Greenhouse gases have been around longer than human life. They are part of the reason life on Earth was able to flourish, because the gases made it warm enough for plants and animals to thrive. However, if Earth becomes too warm or too cold, it can harm animal and plant life, so the greenhouse gases must remain in the right proportions in the atmosphere.
Since the beginning of the industrial revolution, humans have started releasing more greenhouse gases into the earth’s atmosphere than needed to maintain a healthy greenhouse effect. The increased concentrations of greenhouse gases have occurred through activities such as modernized manufacturing, transportation and agricultural practices. Even worse, our industrial actions have led to the creation of new greenhouse gases that only harm the atmosphere, which has increased the speed of global warming.
Global Warming & Greenhouse Gases
Carbon dioxide (CO2) is the most common greenhouse gas, accounting for almost 75% of all greenhouse gas emissions. Atmospheric CO2 is released by natural events such as volcanic eruptions, and humans exhale it when we breathe.
The problem with carbon dioxide is that the planet has experienced a massive jump in the amount of CO2 in the atmosphere over the last two hundred years. The increase in CO2 concentrations can primarily be traced to the burning of fossil fuels to run factories and power vehicles.
Reducing our reliance on fossil fuels and switching to clean energy can help to reduce the emission of carbon dioxide gas.
Methane (CH4) occurs naturally through decomposition. When organic matter decomposes, it releases methane into the atmosphere, and this natural process has been occurring for millions of years.
What Are Greenhouse Gases And Where Do They Come From?
The increase in atmospheric methane in the last two centuries comes from human activities such as cattle farming, rice production and raising organic matter in landfills. Unfortunately, although methane is only 17% of greenhouse gases, it is much more harmful than CO2 because the GWP is about 28 times higher.
We can help reduce methane emissions by cutting back on meat consumption and reducing the amount of waste we send to the landfill.
Nitrous oxide (N2O) is another naturally occurring greenhouse gas that has recently spiked out of proportion in the atmosphere due to fossil fuel combustion. This increase can be attributed to a rise in the use of nitrous oxide in both commercial and organic fertilizers.
While nitrous oxide is only 6% of greenhouse gases, it is 265 times as powerful as CO2 when it comes to its ability to warm the planet. This makes it a much more harmful gas to release into the atmosphere, especially when the levels get out of proportion.
Carbon Dioxide (co2)
We can reduce the amount of nitrous oxide in the atmosphere by reducing our use of fertilizers and fossil fuels.
Industrial gases, or fluorinated gases, are GHGs created exclusively by human activities. The leading culprits include hydrofluorocarbon (HFC), perfluorocarbon (PFX), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3). Industrial gases are primarily generated by refrigerants, air conditioning and solvents used in manufacturing.
While these gases currently account for only around 2% of total greenhouse gas emissions in the atmosphere, they are particularly powerful in their ability to warm the planet. Industrial gases are thousands of times stronger than CO2, and they will remain in the atmosphere for hundreds (and maybe even thousands) of years because they are not a natural part of our environment.
This means that even a small concentration of these chemicals and greenhouse gases in the atmosphere can lead to significant effects on global warming. Emissions of these industrial gases increased by 86% in the United States between 1990 and 2019, a trend that was very dangerous for the planet.
What Is The Anthropogenic Greenhouse Effect?
To counter these numbers, we need to develop methods to contain and eliminate manufacturing byproducts before they enter the atmosphere.
Although water vapor (H2O) and ozone (O3) are technically greenhouse gases, climate scientists do not track their numbers because they are not typically considered to be harmful.
Water vapor, technically the most abundant greenhouse gas, only stays in the atmosphere for a couple of days before it returns to Earth in the form of precipitation, such as rain or snow.
Ozone is another greenhouse gas that can be useful or harmful, depending on where it is in the atmosphere.
Greenhouse Gas Concentrations Further Increased In 2022, Finds Analysis Of Global Satellite Data
While many GHGs are naturally present in the world at certain levels, climate change can occur when the proportion of these gases in the atmosphere gets out of balance. If the concentration of GHGs in the atmosphere becomes too high, it traps too much heat on the Earth’s surface, and this leads to rising temperatures.
A majority of scientists believe that human activity is the leading cause of increased levels of greenhouse gases. Thus, an overreliance on fossil fuels, overuse of industrial fertilizers and under-regulation of manufacturing processes all have an impact on climate change.
The earth has always had greenhouse gases, and many greenhouse gases are naturally occurring and do not bother the planet when they are kept in the proper proportions to maintain our greenhouse effect.
However, when more greenhouse gases are in the atmosphere than should be, they directly accelerate global warming. This typically happens because of human activity, especially since the most powerful greenhouse gases are created artificially.

Many of the chemical compounds in the Earth’s atmosphere act as greenhouse gases. When sunlight strikes the Earth’s surface, some of it radiates back to space as infrared radiation (heat).
