Final answer:
The primary contributors to climate change/global warming are the emission of greenhouse gases, such as carbon dioxide and methane, released through human activities like the burning of fossil fuels. Human influences, particularly the release of greenhouse gases, are the major causes of climate change.
Step-by-step explanation:
The primary contributors to climate change/global warming are the emission of greenhouse gases, such as carbon dioxide (CO2) and methane, which are released through human activities. The main source of these emissions is the burning of fossil fuels for energy consumption. Other factors, such as deforestation, agriculture, and manufacturing, also contribute to these emissions. In addition to greenhouse gases, manmade changes like the increase in near-surface ozone and aerosols can raise the surface temperature. Overall, human influences, particularly the release of greenhouse gases, are the major causes of climate change.
