Global Warming & Greenhouse Effects

• The greenhouse effect is the process by which gases in Earth's atmosphere trap heat from the sun, keeping our planet warm enough to support life.
• Greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), fluorinated gases (HFCs, PFCs, SF6), water vapor (H2O), ozone (O3), and chlorofluorocarbons (CFCs).
• Carbon dioxide (CO2) is the most important greenhouse gas, accounting for about 75% of all human-caused emissions.
• Carbon dioxide (CO2) is released into the air when we burn fossil fuels like coal, oil, and gas or drive cars that run on these fuels.
• Methane (CH4) comes mainly from livestock farming and rice paddies.
• Water vapor (H2O) is a natural greenhouse gas that plays an essential role in regulating Earth's temperature.
• Nitrous Oxide (N2O): Nitrogen fertilisers used in agriculture are one of the main sources of this gas.
• Fluorinated gases are synthetic chemicals used as refrigerants, solvents, and propellants.
• Global warming refers to the gradual increase in average temperatures around the world caused by human activities such as burning fossil fuels and deforestation.
• Greenhouse gases trap heat in the atmosphere, leading to global warming and climate change.
