Greenhouse Effect & Global Warming

Definition:

• The enhanced greenhouse effect refers to the increased trapping of heat in the Earth's atmosphere due to higher concentrations of greenhouse gases, resulting in global warming.

Causes of the Enhanced Greenhouse Effect:

• Increased Greenhouse Gas Emissions: The burning of fossil fuels (coal, oil, and natural gas) for energy, transportation, and industrial processes releases large amounts of carbon dioxide (CO2) and other greenhouse gases into the atmosphere.
• Deforestation: The removal of forests reduces the planet's capacity to absorb CO2 through photosynthesis, contributing to higher greenhouse gas levels.
• Industrial Processes: Certain industrial activities release potent greenhouse gases such as methane (CH4) and nitrous oxide (N2O).

Consequences of the Enhanced Greenhouse Effect:

• Global Warming: The Earth's average temperature is rising, leading to climate change, which includes more frequent and severe heatwaves.
• Melting Ice: Higher temperatures are causing glaciers and polar ice caps to melt, contributing to rising sea levels.
• Sea-Level Rise: Rising sea levels threaten coastal communities, causing erosion and increased flooding.
• Extreme Weather Events: An increase in the intensity and frequency of extreme weather events, such as hurricanes and droughts, is observed.
• Ocean Acidification: Elevated CO2 levels also lead to ocean acidification, harming marine life and ecosystems.

Mitigation and Adaptation:

• Efforts to mitigate the enhanced greenhouse effect include reducing greenhouse gas emissions, transitioning to renewable energy sources, and reforestation. Adaptation measures are also needed to cope with the changes that are already occurring.
