What are Greenhouse Gases and the Greenhouse Effect?
WHAT ARE GREENHOUSE GASES?
Greenhouse gases are any gas that has the property of absorbing infrared radiation (net heat energy) from the earth’s surface and returning it to the earth’s surface.
Gases that trap heat within Earth’s atmosphere are called Greenhouse gases. They allow sunlight to pass through the atmosphere but prevent sunlight from escaping.
Like the glass of a greenhouse, the gases in the Earth’s atmosphere stop the heat of the sun and sustain life. These “greenhouse gases” allow sunlight to pass through and warm the planet, but prevent this heat from escaping from the atmosphere into space. Without them, the earth would be too cold to sustain life as we know it.
The major greenhouse gases are:
- Water vapor
- Carbon dioxide
- Methane
- Ozone
- Nitrous oxide
- Chlorofluorocarbons
Greenhouse gases are heat traps. They got their name from the greenhouse. A greenhouse is full of windows that allow in the sun. This sunlight creates warmth. The great strategy of the greenhouse is that it cannot survive that heat.
This is how greenhouse gases work. They allow sunlight to pass through the atmosphere but prevent sunlight from escaping. Overall, greenhouse gases are a good thing. Without them, our planet would be very cold and life would not exist as we know it. But this is a very good thing. Scientists are concerned that human activities are releasing more of these gases into the atmosphere.
HOW DOES THE GREENHOUSE EFFECT WORK?
As the name suggested greenhouse effect, affects works like a greenhouse! The greenhouse is a building with glass walls and a glass roof. Greenhouses can grow plants like tomatoes and tropical flowers.
A greenhouse will remain warm even in winter. During the day, sunlight illuminates the greenhouse and warms the plants and the air. At night, it is cold outside, but the greenhouse stays very warm inside. This is because the glass walls of the greenhouse trap the warmth of the sun.
The greenhouse effect works similarly on Earth. Atmospheric gases, such as carbon dioxide, dissipate heat like the glass roof of a greenhouse. These hot trap gases are called greenhouse gases.
During the day the sun shines within the atmosphere. The Earth’s surface is heated by sunlight. At night, the earth’s surface cools and the heat is released back into the air. But in some hot climates, it is trapped by greenhouse gases. This is why our earth warms up to an average of 58 degrees Fahrenheit (14 degrees Celsius).
HOW DOES THE GREENHOUSE EFFECT IMPACT HUMANS?
Human activities are changing the natural greenhouse effect of the earth. The burning of fossil fuels such as coal and oil causes more carbon dioxide in our atmosphere.
NASA has increased the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Because of the high levels of these greenhouse gases, the Earth’s atmosphere will become more and hotter. It warms the earth.
WHAT IS THE DIFFERENCE BETWEEN “GREENHOUSE EFFECT” AND “GREENHOUSE GAS”?
A greenhouse is a structure usually made of glass in which the temperature and humidity can be controlled for the cultivation or protection of plants. A greenhouse is designed to trap heat from the sun’s rays, and it works to keep plants warm even when it is cold outside. Although the Earth does not have a clear layer of matter, some molecules in our atmosphere absorb the Earth’s heat, which basically traps less energy. This is called the greenhouse effect and the molecules that trap heat are called greenhouse gases.
Although greenhouse gases do not create a greenhouse-like surface, they have a similar effect on keeping our planet warm, so the term greenhouse effect is a good description. The greenhouse effect makes our planet’s temperature brighter and more favorable to living things.
Greenhouse gases (GHGs) include carbon dioxide, water vapor, methane, ozone, nitrous oxide, and fluoride gases. These molecules in our atmosphere are called greenhouse gases. Some of these gases may not be present in our atmosphere, but they can have a profound effect. These molecules eventually release heat energy and often absorb another greenhouse gas molecule.
More technically: Atmosphere and clouds are similar gases because greenhouse gases effectively absorb the thermal infrared radiation emitted from the Earth’s surface. Atmospheric radiation is emitted on all sides, including the bottom of the Earth’s surface. Therefore, greenhouse gases trap heat within Earth’s atmosphere. This is called the greenhouse effect.
WHAT IS REDUCING THE GREENHOUSE EFFECT ON EARTH?
Like a glass greenhouse, the earth’s greenhouse is full of plants! Plants can balance the greenhouse effect on the earth. All plants – from giant trees to small phytoplankton in the oceans – take in carbon dioxide and release oxygen.
The ocean absorbs a lot of carbon dioxide in the air. Unfortunately, the increased carbon dioxide in the ocean replaces water and makes it more acidic. This is called ocean acidification.
More acidic water is harmful to some marine life, such as shellfish and coral. Warm oceans – from the vast majority of greenhouse gases in the atmosphere – are also harmful to these organisms. The main cause of coral bleaching is hot water.
Now you can understand what the greenhouse effect is and how it contributes to the effects of climate change. Did you know that man-made greenhouse gases contribute the most to global warming?
Not everyone has the same effect, they do not come from the same source, and in this way, each atmosphere lasts for a different time. To teach you a little more about these gases, we have created a static infographic that lists all these data on greenhouse gases.
We avoided other variables such as anthropogenic origin and black carbon in ice due to their low efficiency.
HOW DO GREENHOUSE GASES CONTRIBUTE TO GLOBAL WARMING?
Human gas contains five gases, which contribute to global warming – up to 95% of the total. Here you will find the source of their expulsion, how much time they spend in the atmosphere, and what percentage they contribute to the greenhouse effect.
Carbon dioxide accounts for 53% of global warming. It is the result of processes such as fuel consumption, deforestation, and the production of cement and other materials. Its length in the atmosphere varies, but it is always very high: 80% may take 200 years and the other 20% may take 30,000 years to disappear.
Methane is the boundary of greenhouse gases that have the greatest impact on global warming (15%). It is derived from activities such as livestock production, agriculture, wastewater treatment, natural gas, and oil supply. Coal mining, fuel consumption, and waste tips are also excluded. It lives in the atmosphere for an average of 12 years.
Halogenated compounds such as CFC, HCFC, HFC, PFC, SF6, NF3, refrigeration, air conditioning, electrical and electronic equipment, medicine Global warming is the result of the production of chemicals from various fields. Metallurgy, etc. Their duration in the atmosphere varies from a few months to thousands of years, depending on the type of compound.
Tropospheric ozone affects 11% of global warming. It is the result of a reaction between carbon monoxide (CO), nitrogen dioxide (NO), and VOCs (volatile organic products). These gases do not remain in the atmosphere like other months, for most months.
Finally, nitrous oxide contributes 11% of global warming. It comes mainly from fertilizers, fuels, chemical production, and wastewater treatment, and can persist in the atmosphere for up to 114 years.
HOW TO AVOID CREATING GREENHOUSE EFFECT GASES?
It is necessary to reduce greenhouse gas emissions to avoid global warming. The best approach is committed to renewable energy that generates clean electricity without harming the environment or polluting the air. The upgrade will also help protect the oceans and forests, which are natural carbon sinks that absorb some carbon dioxide.
