Question
Write about greenhouse gases.
Answer
Greenhouse gases are those gases that trap heat in the Earth’s atmosphere, contributing to the greenhouse effect and causing global warming. The major greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases such as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). These gases are released into the atmosphere through various human activities such as the burning of fossil fuels, deforestation, agriculture, and industrial processes. The concentrations of these gases have been increasing rapidly over the past few decades, leading to significant climate change and its associated impacts on ecosystems and human societies.
