how does human activity contribute to greenhouse gases?
351177
Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gas- es, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.

Climate Change. ... In addition to its local effects, burning organic materials on a large scale, like what is done with slash-and-burn agriculture, emits greenhouse gases, which contribute to global climate change. It is estimated that 25% of the world's total greenhouse gas production comes from deforestation alone.

Gases which contributes in greenhouse effect are carbon dioxide, methane, nitrous oxide, ozone, water vapour, Chlorofluorocarbons (CFCs) and, Hydrofluorocarbons (HCFCs and HFCs). Hydrogen is not a greenhouse gas. Hence, the correct answer is 'Hydrogen'.

Those scraps of energy, and the associated greenhouse gases emitted with each online activity, can add up. The carbon footprint of our gadgets, the internet and the systems supporting them account for about of global greenhouse emissions, according to some estimates.

Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down rainforests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.

Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem.

Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2018, CO2 accounted for about 81.3 percent of all U.S. greenhouse gas emissions from human activities.

Indeed, carbon dioxide, a byproduct of fossil fuel combustion, is the principal greenhouse gas contributing to global warming. However, other greenhouse gases including methane, nitrous oxide, and a number of industrial-process gases also are important contributors to climate change.

Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.

A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming.
1462187
Properties of Nitrous Oxide. In 2018, nitrous oxide (N2O) accounted for about 6.5 percent of all U.S. greenhouse gas emissions from human activities. Human activities such as agriculture, fuel combustion, wastewater management, and industrial processes are increasing the amount of N2O in the atmosphere.

The main greenhouse gases are: Water vapor. Carbon dioxide. Methane.

Agriculture contributes to climate change both by anthropogenic emissions of greenhouse gases and by the conversion of non-agricultural land such as forests into agricultural land. In 2010, agriculture, forestry and land-use change were estimated to contribute 20–25% of global annual emissions..

Many greenhouse gases occur naturally in the atmosphere, such as carbon dioxide, methane, water vapor, and nitrous oxide, while others are synthetic. Those that are man-made include the chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs) and Perfluorocarbons (PFCs), as well as sulfur hexafluoride (SF6).

The enhanced greenhouse effect is the increasing amount of greenhouse gases in the atmosphere as a result of human activities, while on the other hand, global climate change is the change in the global pattern of climate precipitation, temperature, winds, and pressure systems.
907245
Sources of greenhouse gases Some greenhouse gases, like methane, are produced through agricultural practices, including livestock manure. Others, like CO2, largely result from natural processes like respiration and from the burning of fossil fuels like coal, oil and gas.

One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, or CO2.
