Global Warming and Greenhouse Gases

Definition and Causes

• Global warming refers to the long-term rise in the average surface temperature of the Earth due to the increasing levels of greenhouse gases in the atmosphere.
• These gases, such as carbon dioxide and methane, trap heat from the sun and prevent it from being released back into space, leading to a warming effect.

Greenhouse Gases

• Carbon dioxide (CO2): primary contributor to global warming, released through human activities like burning fossil fuels, deforestation, and land-use changes.
• Methane (CH4): released through agriculture, natural gas production and transport, and landfills.
• Water vapor (H2O): most abundant greenhouse gas, but its concentration is largely controlled by temperature.

Effects of Global Warming

• Rising Sea Levels: melting of glaciers and ice sheets, leading to coastal erosion and flooding.
• Extreme Weather Events: increased frequency and intensity of heatwaves, droughts, and heavy rainfall.
• Changes in Precipitation Patterns: altered patterns of rainfall and snowfall, leading to droughts and floods.
• Loss of Biodiversity: extinction of species, disruption of ecosystems, and changes in migration patterns.

Consequences of Global Warming

• Food and Water Security: impacts on agricultural productivity, food availability, and water scarcity.
• Human Health: increased risk of heat-related illnesses, respiratory problems, and the spread of disease.
• Economic Impacts: damage to infrastructure, increased costs for healthcare and emergency response, and loss of productivity.

Solutions to Global Warming

• Reduce Greenhouse Gas Emissions: transition to renewable energy sources, increase energy efficiency, and implement policies to limit emissions.
• Carbon Capture and Storage: technologies that capture and store CO2 emissions from power plants and industrial processes.
• Sustainable Land Use: practices like reforestation, agroforestry, and sustainable agriculture to sequester carbon dioxide.
