Greenhouse gases (GHGs) are compounds crucial to Earth's climate system. They are essential for maintaining the planet's temperature, but human actions have greatly raised their levels, causing global warming and climate change. Comprehending these gases and their effects is key to creating effective climate change mitigation strategies.<br><br>The main greenhouse gases are [https://www.institutocervantesguerrero.edu.mx/perfil-de-lp/josephvyin/ Low carbon] dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. Each of these gases has different sources and varying capabilities to trap heat in the atmosphere, known as their global warming potential (GWP).<br><br>Carbon dioxide (CO2) is the most common GHG, mainly released from burning fossil fuels like coal, oil, and natural gas for energy and transportation. Deforestation and specific industrial processes also emit large quantities of CO2. Although CO2 is less potent on a per-molecule basis than other GHGs, its abundance makes it the leading contributor to human-induced climate change.<br><br>Methane (CH4) is a highly potent GHG, with a GWP over 25 times greater than CO2 over a century. Methane is released during coal, oil, and natural gas production and transport, and from livestock, agriculture, landfills, and waste treatment. Though methane stays in the atmosphere for less time than CO2, its high GWP makes it essential to target in mitigation efforts.<br><br>Nitrous oxide (N2O) is emitted from agricultural and industrial activities and during fossil fuel and waste combustion. With a GWP nearly 300 times that of CO2, nitrous oxide is a powerful greenhouse gas, though it is present in the atmosphere in much smaller concentrations.<br><br>Fluorinated gases encompass hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF8), among others. These synthetic gases are used in a variety of industrial applications, including refrigeration, air conditioning, and electronics manufacturing. Fluorinated gases possess very high GWPs, making even minor emissions major contributors to climate change.<br><br>The effects of greenhouse gases go beyond just warming the planet. They cause extreme weather events, sea level rise, and changes in ecosystems and biodiversity. Reducing GHG emissions needs a unified global effort, including policy changes, technological innovation, and shifts in consumer behavior.<br><br>Greenhouse gases are central to the discussion on climate change. While they are necessary for life on Earth, human activities have disrupted their natural balance, leading to significant environmental challenges. Tackling these challenges demands a thorough understanding of GHGs and coordinated efforts to cut their emissions and mitigate their impacts.
