  What is GlobalWarming? • Definition – Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases like carbon dioxide (CO2). • Main Contributes - • Fossil fuel burning (coal, oil, natural gas) • Deforestation • Industrial processes • Key Greenhouse Gases - • Carbon dioxide (CO2) • Methane (CH4) • Nitrous oxide (N2O)
• 3.
  Causes Of GlobalWarming • Human Activities - • Burning of Fossil Fuels : Power plants, cars, and factories emit CO2. • Deforestation : Trees absorb CO2; removing them reduces Earth's ability to regulate CO2. • Agriculture : Livestock production emits methane, and fertilizers release nitrous oxide. • Natural Factors - • Solar radiation variation (less significant than human impact). • Volcanic activity (short-term effect on climate). 12/28/2024 3

  Impacts of GlobalWarming • Rising temperatures : Average global temperatures are increasing, leading to more frequent heatwaves. • Melting Ice Caps : Arctic and Antarctic ice is melting, contributing to sea-level rise. • Extreme Weather Events : More intense storms, floods, and droughts. • Ecosystem Disruption : Threatens biodiversity, alters habitats, and affects food security. 12/28/2024 4

  Solutions to CombatGlobal Warming • Renewable Energy : Transition to solar, wind, and hydroelectric power. • Energy Efficiency : Improve buildings, transportation, and industrial practices to reduce energy consumption. • Reforestation : Plant trees to absorb CO2. • International Agreements : Global efforts like the Paris Agreement to reduce emissions. • Personal Actions : Reduce waste, use public transport, and adopt a sustainable lifestyle. 12/28/2024 5
