Global warming is primarily caused by human activities, such as the burning of fossil fuels and deforestation, which release large amounts of greenhouse gases into the atmosphere.
The industrial revolution and the subsequent increase in the use of coal and other fossil fuels for energy production have significantly contributed to global warming.
Land-use changes, including deforestation and urbanization, play a crucial role in global warming by reducing the earth's capacity to absorb carbon dioxide and altering the balance of natural greenhouse gases.
The release of methane, a potent greenhouse gas, from activities such as agriculture, landfills, and the extraction of fossil fuels, is a significant contributor to global warming.
The depletion of the ozone layer, caused by human-made substances, contributes to global warming by allowing more solar radiation to reach the Earth's surface.
While natural factors, such as volcanic eruptions and variations in solar radiation, have influenced climate change in the past, the current global warming trend is primarily driven by human-induced greenhouse gas emissions.
