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.
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.
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.
Humans began adding significant amounts of greenhouse gases to the atmosphere during the Industrial Revolution in the mid-18th century. This period marked the widespread use of fossil fuels such as coal, oil, and gas, leading to a rapid increase in carbon dioxide emissions.
When humans burn fossil fuels, such as gasoline or coal, they release carbon dioxide and other greenhouse gases into the atmosphere. These greenhouse gases contribute to global warming and climate change by trapping heat in the Earth's atmosphere.

CO2; Carbon Dioxide
Humans affect the production of greenhouse gases in the atmosphere, and have done since the beginning of the Industrial Age (1750s).Examples of this would bedeforestation, cutting down or burning trees, which adds carbon dioxide to the air, and prevents its reabsorption.burning fossil fuels (coal oil and natural gas) to generate electricity or to drive transport, which adds carbon dioxide.raising cattle, which belch methane, a greenhouse gas 21 times more dangerous than carbon dioxide.
When humans burn fossil fuels, carbon dioxide (CO2), methane (CH4), and other greenhouse gases are released back into the atmosphere. These gases contribute to the greenhouse effect, trapping heat and causing global warming and climate change.
