For global climate change the issue is burning fossil fuels to produce energy for a huge number of purposes (heating, industry, transportation, electrical energy, etc.). Unless countermeasures are in place every time that fossil organic material is oxidized (burnt) the products end up as CO2 and other harmful gasses (SO2, NO3 etc) in the atmosphere.
Note that it is not only the atmosphere that takes all this anthropogenic CO2 (man-made CO2), it also enters the ocean where it is present as dissolved CO2, CO3-- and HCO3- and leads to a phenomenon called ocean acidification, which is extremely harmful to all organisms that produce carbonate shells or edifices like corals and mussels.
Because this CO2 has been hidden underground for 300 million years, releasing it now means the carbon cycle cannot deal with it, and it is building up in the atmosphere causing global warming and climate change.
By burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).

The greenhouse effect warms the gases in the atmosphere.
Of course, greenhouse gases keep the Earth from being one large popsicle. The newest studies of the atmosphere indicate that the atmosphere is pretty stable, now. The reason is that nearly all of the greenhouse gases are water vapor mostly evaporated from the oceans.
True. The increase or decrease of greenhouse gases does affect the atmosphere. This includes globally cold or hot temperatures, along with shifts in the climate and weather the world over.
They slow the loss of heat
The increase of greenhouse gases in the atmosphere, particularly carbon dioxide, is causing global warming.
No, greenhouse gases do not reduce the hole. In the contrary, they increase the size of the hole.
The greenhouse gases are increasing global warming.
The greenhouse effect warms the gases in the atmosphere.
It means there is more greenhouse gases in the air. Greenhouse gases absorb and hold the sun's heat. So an increase means that the atmosphere gets warmer, globally (global warming).
When greenhouse gases like carbon dioxide increase in the atmosphere then the temperature rises. Greenhouse gases capture heat rising from the surface of the earth and prevent it escaping to space.

That means that due to the presence of an atmosphere, and specific gases in the atmosphere, the average temperature on the planet is higher than it would have without an atmosphere - or without specific gases. Greenhouse gases, that increase the average temperature, include carbon dioxide (CO2) and methane (CH4).
