What is the gradual increase of the average air temperature in the earths lower atmosphere?

The gradual increase of the average air temperature in the Earth's lower atmosphere is known as global warming. This is primarily caused by the release of greenhouse gases into the atmosphere, which trap heat and lead to a rise in temperatures. Human activities, such as burning fossil fuels and deforestation, are the main contributors to this phenomenon.

What are then two main gases found in earths atmosphere?

The two main gases are Nitrogen (N2) and Oxygen (O2), which comprise around 78% and 21% of the atmosphere by volume respectively. The remaining 1% is mostly Argon (Ar), followed by Carbon Dioxide (CO2) as well as several other gases present in trace amounts. All of these figures are for dry air, however water vapour (H2O) is also present in air at levels of up to 4%, but this is highly variable depending on localised conditions, and it makes up a lower percentage of the atmosphere as a whole.
