Greenhouse gases have been increasing in concentration primarily due to human activities, such as burning fossil fuels for energy, deforestation, and industrial processes. These activities release significant amounts of carbon dioxide, methane, and nitrous oxide into the atmosphere. Additionally, increasing agricultural practices and land-use changes contribute to the rise in these gases. As a result, the enhanced greenhouse effect leads to global warming and climate change.
There have always been greenhouse gases keeping the planet comfortable for life. They are part of the water cycle and the carbon cycle. Greenhouse gases hold back some of the sun's heat to keep the planet from freezing.The greenhouse effect that scientists are worried about now is the enhanced, or accelerated greenhouse effect, which has been warming the planet steadily for the last 200 years, since man started burning fossil fuels (coal, oil and natural gas). Burning these releases extra carbon dioxide that has been stored away for millions of years in the coal and oil. This extra carbon dioxide is causing the present greenhouse effect.
The largest contributor of greenhouse gases into the atmosphere is the oil and gas company Saudi Aramco. They have consistently been identified as one of the biggest emitters of carbon dioxide globally.
Nitrogen and oxygen are the most abundant gases near Earth's surface, making up about 99% of the atmosphere. Water vapor can also have high concentrations, especially in humid environments. Carbon dioxide, although present in much smaller quantities, has been increasing in concentration due to human activities.

The Earth has always has a greenhouse effect, it has kept our planet warmer than it should have been given its albedo and distance from the sun. The present concern is due to the enhanced greenhouse effect caused by the emission of carbon dioxide and a limited number of other gases into the atmosphere due to human activities.

The main objective of the greenhouse effect is to keep the earth warm. It has been doing this successfully for millions of years. Unfortunately we have caused an enhanced (or accelerated) greenhouse effect which is causing global warming.
The greenhouse effect has been a natural phenomenon on Earth for millions of years. However, human activities, such as burning fossil fuels, have significantly increased the concentration of greenhouse gases in the atmosphere since the Industrial Revolution, intensifying the greenhouse effect and leading to global warming.
Well in the past 100 years or so there have been increasing amounts of greenhouse gases in the atmosphere due to anthropomorphic reasons like the industrial revolution and the burning of fossil fuels.
Yes, levels of greenhouse gases, such as carbon dioxide and methane, have been increasing steadily in the Earth's atmosphere over the past century due to human activities like burning fossil fuels and deforestation. These gases trap heat and contribute to global warming and climate change.
Greenhouse gases in the atmosphere capture heat. We are continuing to add extra greenhouse gases (by burning fossil fuels) and this is causing the warming. The great forests that used to remove carbon dioxide (one of the greenhouse gases) from the atmosphere have been destroyed.
Sulfur hexafluoride (SF6) is a greenhouse gas that has a relatively short atmospheric lifetime compared to other gases like carbon dioxide and methane. It is a potent greenhouse gas and is used primarily in electrical transmission and distribution systems.

Carbon dioxide and methane are naturally occurring greenhouse gases, but are also man made. CFCs previously used as propellants for aerosol and as refrigerants were really damaging greenhouse gases. These have since been replaced.
Some "greenhouse gases" have been reduced (or at least attempts have been made to limit their production in the future).
