What are the major factors affecting global climate change?.

Global climate change is influenced by several major factors:

Key Facts

• Greenhouse Gases: Human activities, particularly the burning of fossil fuels, have significantly increased the concentration of CO2 in the atmosphere, reaching over 400 ppm in 2023.
• Deforestation: About 13 million hectares of forests are lost annually, contributing to increased carbon emissions and reduced biodiversity.
• Industrialization: Since the mid-20th century, industrial processes have released large quantities of pollutants, affecting air quality and climate.
• Agricultural Practices: Livestock farming generates methane, a potent greenhouse gas, accounting for approximately 14.5% of global emissions as of 2021.

Examples or Use Cases

• Countries implementing renewable energy sources, such as solar and wind, show a decrease in greenhouse gas emissions.
• Deforestation reduction initiatives in the Amazon are crucial for biodiversity and climate regulation.

FAQs

• What role do oceans play in climate change? Oceans absorb about 30% of CO2 emissions, but their capacity is diminishing.
• How does urbanization contribute to climate change? Increased urban heat islands exacerbate local temperatures and energy consumption.
