Human activity is increasing the greenhouse effect.
A:The greenhouse effect is caused by greenhouse gases which trap warmth on the earth's surface. Increases in greenhouse gases, particularly carbon dioxide result in enhanced global warming, or a rise in average global temperatures.Since the beginning of the Industrial Age, human activities have increased the concentration of atmospheric carbon dioxide by around 35 per cent, from its long-term average of 260-280 parts per million (ppm) to the present 380 ppm. This has chiefly resulted from burning fossil fuels such as coal, oil and natural gas, manufacture of cement and deforestation.
Carbon dioxide concentrations in the atmosphere have gone up by approximately 35 percent since the 1900s, rising from 280 parts per million by volume to 387 parts per million in 2009. ChaCha and you know!
The burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).
The increase is in greenhouse gases (CO2. methane) in the atmosphere. These gases and others are produced both naturally and by industrial activities including burning of fossil fuels.
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.

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.
They slow the loss of heat
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.
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).
The increase of greenhouse gases in the atmosphere, particularly carbon dioxide, is causing global warming.
