Greenhouse gases affect the heat flow into and out of the Earth's atmosphere by selectively allowing certain wavelengths of radiation to pass through while absorbing and re-emitting other wavelengths. This process alters the balance of energy in the atmosphere, contributing to the greenhouse effect.

Here's how it works:

Now, to address the difference between greenhouse gases and global warming:

• Greenhouse Gases: These are gases in the Earth's atmosphere that have the property of absorbing and re-emitting infrared radiation. They include carbon dioxide (CO2), methane (CH4), water vapor (H2O), and others. Greenhouse gases naturally exist in the atmosphere and are necessary to maintain a habitable climate. However, human activities, such as burning fossil fuels and deforestation, have led to an increase in their concentrations, intensifying the natural greenhouse effect and contributing to global warming.
• Global Warming: This refers to the long-term increase in the average global temperature due to the enhanced greenhouse effect caused by the increased concentrations of greenhouse gases in the atmosphere. Global warming is a consequence of human activities releasing excessive amounts of greenhouse gases, primarily CO2, into the atmosphere. It leads to various impacts on the Earth's climate, including rising sea levels, more frequent and severe heatwaves, changes in weather patterns, and disruptions to ecosystems.

In summary, greenhouse gases affect the heat flow into and out of the Earth's atmosphere by absorbing and re-emitting infrared radiation, leading to the greenhouse effect. Global warming is the outcome of human-induced increases in greenhouse gas concentrations, resulting in the Earth's average temperature rising over time.

Burning fossil fuels like coal and oil puts more carbon dioxide into our atmosphere. NASA has observed increases in the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth's atmosphere to trap more and more heat. This causes Earth to warm up. The added greenhouse gases absorb the heat. They then radiate this heat. Some of the heat will head away from the Earth, some of it will be absorbed by another greenhouse gas molecule, and some of it will wind up back at the planet's surface again. With more greenhouse gases, heat will stick around, warming the planet. Conduction, radiation, and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere. Greenhouse gas molecules in the atmosphere absorb light, preventing some of it from escaping the Earth. This heats up the atmosphere and raises the planet's average temperature. Earth's greenhouse gases trap heat in the atmosphere and warm the planet. The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor. In addition to these natural compounds, synthetic fluorinated gases also function as greenhouse gases. Certain gases in the atmosphere absorb energy, slowing or preventing the loss of heat to space. Those gases are known as “greenhouse gases.” They act like a blanket, making the earth warmer than it would otherwise be. This process, commonly known as the “greenhouse effect,” is natural and necessary to support life. Greenhouse gases are transparent to incoming (short-wave) radiation from the sun but block infrared (long-wave) radiation from leaving the earth's atmosphere. This greenhouse effect traps radiation from the sun and warms the planet's surface. On its own, methane is 30 times stronger than CO2. It contributes between 10-25% of global warming and though it remains in the atmosphere for less time than CO2 does methane eventually turns into more CO2. Greenhouse gases affect our environment by absorbing high amounts of heat from the sun. Greenhouse gases trap heat from the rays of the sun and warm the atmosphere. As the amount of greenhouse gases are increasing in the atmosphere, they are trapping more and more heat. Global warming is the change in the climate of the earth causing it to heat up whereas the greenhouse effect is a naturally occurring phenomenon, constantly occurring due to the atmosphere and sunlight. As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world in the atmosphere, on land, and in the oceans. The Greenhouse effect is when the heat goes up into space, Greenhouse Gases, block the heat going into space and it goes back to earth. Global Warming is when the earth being overheated by Fossil fuels and Greenhouse gases causing Greenhouse effect. Greenhouse gas = one of the causes of global warming, adding a “blanket” so the Earth cannot lose heat (as infrared) to space as fast as it comes in (as visible light) without warming up.

Greenhouse gases are transparent to incoming (short-wave) radiation from the sun but block infrared (long-wave) radiation from leaving the earth's atmosphere. This greenhouse effect traps radiation from the sun and warms the planet's surface. The greenhouse effect is the heat that escapes in space, the greenhouse gases block this escaping heat and hence it enters the earth. Global warming is the phenomenon in which the earth gets overheated by greenhouse gases and fossil fuels leading to the greenhouse effect. As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world in the atmosphere, on land, and in the oceans. Greenhouse gas = one of the causes of global warming, adding a “blanket” so the Earth cannot lose heat (as infrared) to space as fast as it comes in (as visible light) without warming up. Global warming = what happens when heat arrives faster than it can leave, globally.
