The carbon cycle moves carbon in and out of the atmosphere, the land, plants and animals, and the oceans. Carbon dioxide in the atmosphere is a greenhouse gas that keeps the planet warm. Too much carbon dioxide in the atmosphere, from humans adding it by burning fossil fuels, is causing an accelerated greenhouse effect, global warming.
They have increased the levels of greenhouse gases.
No, global warming began when humans seriously started burning fossil fuels in the Industrial Revolution, adding additional greenhouse gas (carbon dioxide) to the atmosphere.
It depends on the gas. Greenhouse gases will tend to warm the troposphere. Aerosols such as black carbon will tend to block out the sun and cool the atmosphere, though these are generally not gases. Adding ozone-depleting gases will destroy ozone in the stratosphere, allowing more UV radiation to reach the surface which is harmful to life.
Humans have affected the ozone layer in the past by making CFCs (chlorofluorocarbons). The Montreal Protocol has since banned production and the ozone layer is repairing itself.Humans have affected the greenhouse gas layer of the atmosphere by burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity. This releases carbon dioxide (CO2), a greenhouse gas which is now building up in the atmosphere.
All of it . . . the largest amount of greenhouse gas is plain old water vapor. (Humidity) Without the greenhouse gasses, the Earth would be an icy ball with no animals, plants, or humans.
The greenhouse effect occurs when certain gasses in the atmosphere trap infrared radiation. This effect makes the planet warmer than it would be without a greenhouse effect.The greenhouse effect is caused by greenhouse gases; the most important greenhouse gasses in Earth's atmosphere are: water vapor, carbon dioxide, and methane.Recently, the greenhouse effect has gotten stronger. Scientists believe this is because humans have been using large amounts of fossil fuels, which release carbon dioxide when they are burned. Since carbon dioxide is a greenhouse gas, it has caused the planet to warm over the past 150 years.

Everyone contributes to the accumulation of greenhouse gasses, which cause global warming, which causes the ice to melt. If humans were able to remove the greenhouse gasses, then the effect would most likely be reversed.
Geologic refers to rocks, and it certainly isn't caused by rocks. It isn't directly caused by humans, either, though our effect on greenhouse gasses present in the atmosphere is thought to have contributed to an increased number of droughts in recent years.

The enhanced, or accelerated greenhouse effect, is the increased heat in the atmosphere. It is caused largely by humans burning fossil fuels and cutting down forests. Both these activities Lead to more carbon dioxide (a greenhouse gas) in the atmosphere.
