There have been a lot of upward trends in the past 100 years - population, industrialization, use of motor vehicles - each of thee contributes to GHG emissions, particularly carbon dioxide.
In addition, the deforestation of many areas of the world either through logging, climate shifts or the increasing need for agricultural land has reduced the ability of the eco-system to absorb carbon dioxide. Still in the carbon dioxide sequestration area, changing farming practices have reduced the amount of carbon retained in the soil.
Even more, the thawing of much of the permafrost in North America and Europe/Asia has liberated methane, a potent GHG with 21 times the impact of carbon dioxide.
Then again there are new GHGs which were not even thought of 100 years ago - substances like CFCs and SF6 - which are very potent GHGs.
What else can I help you with?
Which part of the greenhouse represents greenhouse gases in the atmosphere?
The glass or plastic walls of a greenhouse represent greenhouse gases in the atmosphere by trapping heat energy inside, much like how greenhouse gases in the Earth's atmosphere trap heat.
What is the beneficial effect of the greenhouse gas?
If it weren't for the Greenhouse Effect, the Earth would be very cold. But it is only good to a certain point. We humans are throwing high levels of greenhouse gases into the air that is causing what we have labeled Global Warming.
Are greenhouse gases helpful?
Greenhouse gases are helpful because they keep the earth warm enough for life. They are essential.Too much greenhouse gases are unhelpful because they make the earth too hot. Global warming is causing climate change which may make the world very uncomfortable for our children and grandchildren.
What if you did not have greenhouse gas?
Without greenhouse gases, Earth would be much colder and unable to support life as we know it. Greenhouse gases, like carbon dioxide and methane, trap heat from the sun and keep our planet at a temperature suitable for living organisms to thrive.
What does greenhouse gases trap?
they absorb it and reach states of higher energy much like the earth does. later they release this energy to the surroundings which means about half of it (statisticly) would be sent back to earth
What greenhouse gases do in the atmosphere?
Greenhouse gases keep the earth warm.Too much greenhouse gas is causing global warming.

How are greenhouses gases helpful?
Greenhouse gases are helpful because they trap heat in Earth's atmosphere, which keeps the planet warm enough to support life. Without greenhouse gases, Earth would be too cold for humans, plants, and animals to survive. However, an overabundance of greenhouse gases can lead to climate change and negative impacts on ecosystems.

How much has the average temperature changed in the last 140years?
The average global temperature has increased by approximately 1.2 degrees Celsius (2.2 degrees Fahrenheit) over the last 140 years. This rise in temperature is primarily attributed to human activities, such as the burning of fossil fuels and deforestation, which have increased the concentration of greenhouse gases in the atmosphere.

Where do greenhouses gases trap energy?
Greenhouse gases are very light but they change how sunlight is reflected back out into space in that greenhouse gases do not allow as much sunlight to be reflected. This increases the amount of energy held within the atmosphere and warms the planet
How do greenhouse gases maintain earth's temperature of earth?
Greenhouse gases trap heat from the sun in the Earth's atmosphere, preventing it from escaping into space. This trapped heat warms the planet, creating a stable temperature range that supports life. Without greenhouse gases, Earth would be much colder and uninhabitable.
What would the Earth's temperature be if there were no greenhouse gases present in the atmosphere?
If there were no greenhouse gases in the atmosphere, the Earth's temperature would be much colder than it is now. Greenhouse gases trap heat from the sun, so without them, the Earth would lose more heat and the average temperature would be significantly lower.
What are the GreenHouse Gas emissions in Antarctica?
Truly, there aren't enough machines producing greenhouse gases on the Antarctic continent to have much effect at all.
