1. Greenhouse gas emissions: The burning of fossil fuels, deforestation, and industrial processes release carbon dioxide, methane, and other greenhouse gases into the atmosphere. These gases trap heat and contribute to the warming of the planet.
2. Land use changes: Deforestation, urbanization, and agriculture practices can alter the Earth's surface and impact the climate. For example, deforestation reduces the number of trees that can absorb carbon dioxide from the atmosphere, leading to increased greenhouse gas levels.
3. Changes in solar radiation: Variations in the sun's energy output can affect the Earth's climate. While natural changes in solar radiation have occurred throughout Earth's history, human activities are currently the primary driver of climate change.
4. Natural factors: Natural processes such as volcanic eruptions, ocean currents, and variations in Earth's orbit can also influence the climate. However, human activities have significantly amplified these natural factors, leading to more rapid and severe climate change.

1. Greenhouse Gases: Greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, are released into the atmosphere through human activities (e.g., burning fossil fuels, deforestation). These gases trap heat in the atmosphere, leading to an increase in global temperatures.
2. Deforestation: Clearing forests reduces the amount of trees available to absorb carbon dioxide from the atmosphere. This results in a net increase in greenhouse gas emissions, contributing to climate change.
3. Agriculture: Methane and nitrous oxide emissions from agriculture (e.g., livestock farming, fertilizer use) contribute to greenhouse gas concentrations. Additionally, the conversion of forests into agricultural land removes carbon sinks and exacerbates climate change.
4. Industrial Processes: Industrial activities, such as manufacturing and electricity generation, release large amounts of greenhouse gases into the atmosphere. For example, the burning of fossil fuels for energy production is a major contributor to climate change.
