Global warming is a significant increase in Earth's average temperature caused primarily by human activities, especially the burning of fossil fuels and deforestation, which release greenhouse gases like carbon dioxide. These gases trap heat in the atmosphere, leading to a rise in global temperatures that result in major climate changes, such as melting ice caps, rising sea levels, and more extreme weather events. These shifts threaten ecosystems, human health, and agriculture, making immediate collective action to reduce emissions, transition to renewable energy, and adopt sustainable practices essential for a healthier planet and future generations
