Why have greenhouse gases levels increased in the atmosphere in the last 200 years?

200 years ago was the start of the Industrial Revolution, when we discovered that we could burn coal in steam engines to run machines. Since then we have been burning fossil fuels (coal, oil and natural gas) all over the world in industry, transport and domestic use.
This has added carbon dioxide to the atmosphere that had been hidden away for 300 million years. The carbon cycle can remove part of this, but not all, and levels have been rising slowly from around 280 parts per million (ppm) to the present levels (2018) of more than 400 ppm.

How humans change the atmosphere of the planet in the past 200 years?
They have increased the levels of greenhouse gases.
Why would increased levels of greenhouse gases contribute to higher temperatures?
Greenhouse gases trap the heat rising fom the earth. Increased levels of greenhouse gases mean that global warming will get worse.
What is the effect of higher levels of greenhouse gases?
More greenhouse gases trap more heat in the atmosphere, causing a global warming and climate change.
What happens to greenhouse gases at natural levels in the atmosphere?
At natural levels of greenhouse gases in the atmosphere (before the Industrial Revolution), the carbon cycle moved carbon dioxide in and out of land, sea and air. Enough carbon dioxide remained in the atmosphere to keep the earth comfortably warm, warm enough for life.
What is the purpose of reducing greenhouse gases?
If we don't reduce the levels of greenhouse gases in the atmosphere the earth will get warmer and warmer. Greenhouse gases trap the sun's heat. Whenever we burn fossil fuels, that is, for transport or to produce electricity, we are adding more and more carbon dioxide into the atmosphere. This is what is causing global warming.

The temperature of the Earth is rising due to the increase of what?
Increased levels of greenhouse gases in the atmosphere are causing global warming.
Why would increased levels of greenhouse gases contribute to higher temperatures?
Greenhouse gases trap the heat rising fom the earth. Increased levels of greenhouse gases mean that global warming will get worse.
Why would increased levels of greenhouse gases contribute to higher tempertures on earth?
Greenhouse gasses 'trap' the warmth of the sun inside the atmosphere. This causes the air temperature to rise.
Global warming is the result of increases in what?
Global warming is the result of increased levels of greenhouse gases (carbon dioxide and methane, largely) in the atmosphere.
On which planet have greenhouse gases increased the temperature to lethal levels?
Venus
How does the increase in greenhouse gases support the theory of global warming?
Part of the theory of global warming is that greenhouse gases capture the earth's heat. If more greenhouse gases are added to the atmosphere then more heat will be retained.We can measure that levels of greenhouse gases have increased, and we can measure that temperatures have risen. These measurements thus support the theory of global warming.
What does the greenhouse do to the gases from the atmosphere?
The greenhouse effect warms the gases in the atmosphere.
What is the effect of higher levels of greenhouse gases?
More greenhouse gases trap more heat in the atmosphere, causing a global warming and climate change.
