LAQ : Discuss briefly the greenhouse effect



The greenhouse effect is a natural process that occurs when certain gases in the Earth’s atmosphere, known as greenhouse gases, trap heat from the sun and prevent it from escaping back into space. These gases include carbon dioxide, methane, nitrous oxide, and fluorinated gases.

While the greenhouse effect is a natural phenomenon, human activities, particularly the burning of fossil fuels, have significantly increased the number of greenhouse gases in the atmosphere, leading to an enhanced greenhouse effect and global warming.

The consequences of global warming can be severe, including rising sea levels, more frequent and severe weather events such as hurricanes, floods, and droughts, loss of biodiversity, and negative impacts on human health.
