Question

how are humans making greenhouse gases of our own

Answer 1

The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. ... Approximately 62 percent of our electricity comes from burning fossil fuels, mostly coal and natural gas.

Answer 2

Answer:

Man-made greenhouse gas:

Major greenhouse gases encompass carbon dioxide, methane, nitrous oxide, and diverse artificial chemicals. Carbon dioxide is extensively mentioned because the maximum critical anthropogenic greenhouse gas as it presently accounts for the best part of the warming related to human activities.

Explanation:

There are each natural and human-caused greenhouse gases. Natural sources consist of breathing and decomposition of vegetation and ocean launch of greenhouse gases to the surroundings. Many natural GHGs arise evidently withinside the surroundings, which include water vapour, carbon dioxide, methane and nitrous oxide.

Some greenhouse gases are artificial, human-made. These consist of for instance chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). They may be found, for instance in aerosol sprays, air conditioning and refrigerants and electronics.

Human-induced emissions come from burning fossil fuels, including oil, coal and herbal gas, and activities like deforestation, agriculture and cement production. According to the  Intergovernmental Panel on Climate Change (IPCC), human activities are answerable for nearly all the growth in greenhouse gases withinside the surroundings during the last a hundred and fifty years.

ICOS measures the maximum critical greenhouse gases withinside the surroundings, ecosystems and ocean: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and water vapour (H2O). In addition, there are different greenhouse gases which include halocarbons, ozone and new artificial greenhouse gases, for instance, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).
