Greenhouse gases (GHGs) are gases that trap heat in the Earth’s atmosphere and contribute to global warming and climate change. They act like a blanket around the Earth, trapping heat that would otherwise escape into space. Some examples of GHGs include carbon dioxide, methane, and nitrous oxide.
How GHGs affect the climate change
While some amount of GHGs in the atmosphere is necessary for life on Earth and forming naturally (e.g., water vapor), human activities like burning fossil fuels, deforestation, and industrial processes have increased GHG emissions to unsustainable levels. This causes the Earth’s temperature to rise, resulting in more frequent and intense heat waves, droughts, storms, and other extreme weather events.
The harmful effects of GHGs also include rising sea levels due to the melting of polar ice caps, which can lead to flooding of coastal areas and loss of habitats for marine life. Changes in temperature and rainfall patterns can also affect crop yields and food production, leading to food scarcity and insecurity.
Therefore, it is important to reduce GHG emissions by adopting sustainable practices such as using renewable energy sources, improving energy efficiency, reducing waste, and conserving natural resources. This can help mitigate the impacts of climate change and ensure a sustainable future for all.
The major greenhouse gases (GHGs)
Carbon dioxide (CO2): This is the most common and well-known GHG, emitted primarily from burning fossil fuels for energy, transportation, and industrial processes.
Methane (CH4): This GHG is emitted primarily from agriculture and waste management, including livestock production and the decomposition of organic waste.
Nitrous oxide (N2O): This GHG is emitted primarily from agriculture and industrial processes, including the use of fertilizers, livestock production, and the production of certain chemicals.
Hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6): These are synthetic GHGs emitted primarily from industrial processes and the use of refrigerants, solvents, and other
